System Overview

WaveCAST provides true, professional audio quality over Wi-Fi , and features DSP audio processing. Setting up and configuring the WaveCAST for the Wi-Fi network is straightforward and simple. Up to four WaveCAST systems can be connected to the same  Wi-Fi network to provide multiple listening channels, supporting 45 connections in unicast mode, or 1500+ in multicast mode with a strong network configuration (see “Router and Network Equipment Selection” on page 7).
The WaveCAST audio processor offers multiple preset audio options. The high quality audio can be optimized for hearing assistance, music can have high- fidelity playback, and voice can be set for maximum speech intelligibility. Custom presets can also be  created to meet specific performance needs.
The new WaveCAST app provides an easy-to-use, intuitive user interface and will be available in iOS or Android. The app allows listeners to easily select their channel and volume level once their personal device is connected to the Wi-Fi network.

Quick Setup Instructions

1. Position the WaveCAST transmitter near the sound system or mixer from which it will receive audio. We do not recommend wall or ceiling mounting, or putting the device on a cart.

2. Connect the power supply to the Power Supply connector located on the back of the WaveCAST. Press in the power button on the front of the WaveCAST. The power button should light up. If not, go back and check the power connections.

3. Choose and configure the audio source. The audio source must be configured in the menu before plugging the source into the jack (except Dante Audio – skip to step 7). Push the Menu button and push the > button once to display AUDIO SOURCE on the  screen. Push the > button to access the audio sources. Using the ^ or v menu buttons, choose between ANALOG LINE IN, MIC, PHANTOM MIC +12V, or DANTE.
   When the desired audio source is displayed, it is active. Press the Menu button to exit the menu.

4. Push the power button to turn the unit off.

5. Connect the audio source to the audio input jack on the rear of the WaveCAST.

6. Push the power button to turn the unit on.

7. If Dante audio is being used, the Dante source must be connected, must be playing audio, and the Dante Controller must be used to route audio from the Dante source to the WaveCAST.

8. With the audio source playing, adjust the Audio Level on the WaveCAST so that the green 0 dB LED generally lights and the red +9 dB LED lights occasionally. To do this while on the main info screen, press the ^ button to increase the audio level in 1.0 dB  steps, or press the v button to decrease the audio level in 1.0 dB steps.

9. Select an Audio Preset. The WaveCAST has three pre-configured Audio Presets to choose from: Hearing Assist, Music, and Voice. A Custom preset is also available. The performance of the WaveCAST is optimized for each of the pre-configured Audio Presets. Using the menu and control buttons on the front of the WaveCAST, push the Menu button, the display will change to show Audio Settings. Use the forward > button to display Audio Source in the selection box. Push the down v button twice to show Audio Presets. Now press the > button to display the list of Presets. Use the ^ and v buttons to alternate between Hearing Assist, Music, Voice and Custom selections. When the desired Audio Preset is displayed, it is active. If Custom is desired, push the > button to enter the custom settings; or, press the Menu button to exit the menu.

10. Connect a CAT 5e Ethernet cable from your local area network, or Wi-Fi router to the connector on the transmitter labelled Ethernet. This network will be used to broadcast the audio.

11. (WaveCAST D only) Connect a CAT 5e Ethernet cable from the Dante network to the connector labelled Dante on the transmitter. Note: Dante IP Address and other settings are configured externally through Dante Controller; there are no settings in the transmitter for Dante, other than choosing Dante as the input source).

12. Once the transmitter detects an active network is present (either Ethernet or Dante), the WaveCAST’s Ethernet control IP address will be displayed in the Add-on module part of the home screen.

13. Open a web browser on a computer or mobile device that is also connected to the same local network as the WaveCAST. In the address bar of the browser, type in the IP address that is shown on the front of the transmitter’s main info screen, and push the enter key on the keyboard. (Note: it is not necessary to type “http://” or “www.” preceding the IP address, just the characters following “IP:”, including the periods)

14. The browser will open the transmitter’s web page, displaying a Login button. Click the log-in button and enter the user name “admin” and the default password “admin”.

15. The web browser will now show the transmitter’s Home Page, which shows the current WaveCAST status info. The tabs at the top navigate to different pages that allow adjustment of the transmitter’s settings.

16. Use a personal device with the WaveCAST App installed to listen to the audio and test that device is working and sounds correct.

Wi-Fi Network Required

The WaveCAST connects to the installation location’s Wi-Fi Network. It does not provide a network on it’s own. The Wi-Fi network will need to be installed and established before the WaveCAST can be used.
You may connect the device to a computer via a hardwired connection to help troubleshoot any networking problems.

Router and Network Equipment Selection

The WaveCAST does not come with its own router or networking equipment. It is intended to be set up on an already existing Wi-Fi network; however, upgrades to your network equipment may be necessary depending on the performance desired from the  WaveCAST. For instance, a higher-end, more powerful router will allow more users to connect to your audio stream than using a cheaper, less powerful router.
The WaveCAST system will put a demand on the network. If the network cannot handle the demand, whether because it is being used for other networking needs or because the networking hardware is not strong enough, the WaveCAST will be unable to reach it’s maximum audience.
When streaming to a small or medium sized audience, a basic networking configuration may suffice. When streaming music using multiple channels (such as having several WaveCAST units on your network), a powerful router and network configuration is more
likely to be required.

Wiring and Connections

Power Supply Connection
Connect the power supply to the Power Supply Jack located on the rear of the WaveCAST server.
Ethernet and Dante RJ-45 Connection
If connecting to a network or directly to a PC, a CAT 5e cable must be used. In some cases, (like older PCs) a crossover cable may need to be used.
Audio Source Connections
IMPORTANT: When a suitable audio source has been determined, you MUST configure the audio source in the menu of the WaveCAST before plugging that source in.
The WaveCAST transmitter will accept the following audio sources:

1. Balanced/Unbalanced Microphone with 12 volt phantom power (DIN 45596) on a 3-pin (XLR) connector.
2. Balanced/Unbalanced microphone with or without phantom power on 1/4 inch (TRS) jack.
3. Balanced/Unbalanced Line on a 3-pin (XLR) connector without phantom power.
4. Dante on an RJ-45 jack (optional).

WARNING:
The WaveCAST is not designed to accept 70 volt speaker signals! This may result in damage to your system. The sound source should come directly from the system mixer or Dante source as a low-level or unprocessed signal.

Multi–Channel Sources
By constructing a simple resistive mixer, stereo (or 3 channel) sources can be connected to the WaveCAST. Additional channels can be accommodated by adding a resistor for each source.
Note: The Dante audio input will automatically mix the left and right channels.

Connecting Additional Sound Systems
The Analog Audio Line Output (RCA) jack can be used for monitoring, recording, or routing the WaveCAST’s processed audio into another sound system. For help connecting your sound system, contact Williams AV’s TechBlue technical support team.
Otherwise, audio output is only available over the Wi-Fi network.

Avoiding Hum in the Audio (as a Result of a Ground Loop)
A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the transmitter’s ground. This method also maintains good radio frequency shielding. Determining the effectiveness of this method for your installation usually requires some experimentation.

Selecting an Audio source Appropriate for Hearing Impaired Listeners
The WaveCAST transmits audio with excellent fidelity. Therefore, the audio source signal should be of the highest audio quality and not subject to a compressor, limiter, reverberation, or other signal processing equipment. While compressed audio is available through the WaveCAST, excessive compression is not helpful to the hearing impaired and can contribute to excessive noise in the audio.
The WaveCAST audio source signal is usually connected to a mixer’s line output signal which is behind the mixer’s parametric equalizers but ahead of any equalization used for house loudspeakers.
If audio delay is available for use in large auditoriums, it’s usually best to use it. Because radio signals travel faster than sound, delaying the transmitted audio so that an average listener (in the middle of the listening area) hears the transmitted audio a few milliseconds after audio from the main sound reinforcement system speaker is helpful. This will also help audience members who lip read.

Controls and Features

Power Button
Latching push-button switch turns the transmitter on or off. The desktop power supply provides power to the unit at all times.
OLED Display
This shows current operation settings and is also used with the menu control buttons for configuring the WaveCAST. Each time the power of the unit is turned on, the OLED Display shows a Williams AV start-up screen. After seven seconds, the default Main Info Screen screen will be displayed. The WaveCAST is now fully operational.
( NOTE: If the transmitter’s internal tests fail, the transmitter will attempt to auto-recover by rebooting itself.)
Audio Input Level Indicator
The bar graph indicator shows audio level in 3dB steps at the input of the audio level processing circuit. The indicator is peak responding and is calibrated so that optimum level is reached when the 0dB LED lights up often and the +9dB only lights occasionally. Use the Audio Level settings in the menu to set the audio levels.
Input Overload Indication
The OLED Display shows an overload warning screen each time the audio signal exceeds the capacity of the input circuit. Either the source of the audio coming in to the WaveCAST needs to be adjusted to correct this or the Audio Input Gain needs to be adjusted.
Menu Controls
The menu system can be navigated via the buttons on the front panel of the device. See “Navigating the Menu” on page 10 for more details.
Headphone Jack
A headset plugged into the headphone jack allows monitoring the WaveCAST audio output after it gets processed.
Main Info Screen and Screen Navigation
The Main Info Screen will show the following information: Device Description, Audio Source, Audio Preset, Audio Input Gain Setting. The IP address will be displayed if the device is connected to the network.
Multiple Channels
Up to 4 WaveCAST systems can be used on the same Wi-Fi network for multi- channel operation. Multi-channel operation will work better on more powerful networks and routers.

Main Info Screen
While navigating through the menu, directional arrows (<, >, ^, v) will show up, indicating that parts of the menu exist off-screen to the left, right, above or below. Use the corresponding buttons on the front panel to navigate the menu.

Navigating the Menu

• While the transmitter is displaying the Main Info Screen, the Up ^ and Down v buttons adjust the Audio Input Gain.
• The Menu button is a Enter/Exit Menu function only. It does not select anything within the menu. It allows the user to quickly return to the Main Info Screen from any place in the menu.
• While the transmitter is displaying the Menu on the screen:• The Up ^ button navigates upward in the menu, changes a setting, or acts as a page up on info screens.
  • The Down v button navigates downward in the menu, changes a setting, or acts as a page down on info screens.
  • The Left < button backs out of the menu one step at a time.
  • The Right > button navigates forward in the menu or selects a setting. When entering a Description, IP Address, or Subnet Mask for the Transmitter, this button advances to the next character.

Screen Time Out
When in the menu system, once a setting is selected, no additional action is necessary.
If no buttons are pressed, after 5 minutes the OLED will return to the Main Info Screen, then after another 10 minutes show a screen saver, then go blank after an amount of time set in the Screen Time-Out preference (see “Screen Time-Out” on page 12).

System Settings

Settings can be selected using the arrows on the front panel of the WaveCAST to navigate the OLED menu system or be set via the web interface by using a computer.
Not all settings are available in the front panel menu or through the web interface, and using both may be necessary for your initial set up.
Audio Settings
The Audio Settings provide the ability to change the audio characteristics for different listening applications, choose the input source, adjust the input level, set audio presets, and adjust the headphone volume.
Audio Source
The Audio Source menu is used to configure the WaveCAST for the audio source jack and type of source that will be used. The audio source must be configured in the menu before plugging the source into the jack.
The Audio Source menu has four possible selections to choose from: Analog Line In, Mic, Phantom Mic +12V, 400 Hz Test Tone or Dante (optional).
Audio Input Gain
The Audio Input Gain adjusts the incoming audio level into the WaveCAST. Changes to the input level will affect the level indicated by the front panel LED’s when audio is present. Audio Input Gain is adjustable from 0 dB to -50 dB in 1 dB steps.
Audio Presets
The Audio Presets allow the user to quickly and easily configure the WaveCAST for common applications. In some cases, the Audio Presets may be the only setup needed for properly configuring the WaveCAST server.
There are three pre-configured and one custom Audio Preset to choose from: Hearing Assist, Music, Voice and Custom. When one of these selections is made, the performance of the WaveCAST is immediately optimized for the needs of that application (an adjustment is automatically made to the Low-pass Filter, High- pass Filter, and Compression). Refer to the chart below for a comparison of the Audio Preset configurations.
By default, the WaveCAST is shipped in the Music mode.

Audio Preset Configuration Table

For music, concerts, and other applications where the highest audio quality is desirable, Music is the recommended mode of operation.
For hearing assistance applications, or applications where the message is critical for listening, Hearing Assist is the recommended mode of operation.
For speaking and other voice applications, Voice is the preferred mode of operation.

Custom Audio Preset
If the three preset configurations do not meet the needs of the venue, the Custom audio preset can be used. The custom preset allows the user to adjust the High-Pass Filter cutoff frequency, Low-Pass Filter cutoff frequency, and choose the Compression Ratio. If the audio preset is changed from Custom to Music, Hearing Assist, or Voice, the Custom settings are overwritten.
High-pass Filter
A high-pass Filter cuts off low frequencies and lets high frequencies pass through. The pole frequency chosen is the point where the cutoff takes effect. The high-pass filter will help to remove low frequency noise from the transmitted audio signal, such as room noise, a line hum, or breath accents picked up from an improperly installed microphone. Available frequencies are: 31, 63, 80, 100, 125, 160, 200, 250, 315, 400, 500, and 630 Hz.
Low-pass Filter
A low-pass Filter cuts off high frequencies and lets low frequencies pass through. The pole frequency chosen is the point where the cutoff takes effect. The low-pass filter will help to remove high frequency noise from the transmitted audio signal, such as hiss in the audio line as a result of room noise, sharp speech sounds, or other uncomfortable high frequency sounds. Availablefrequencies are: 3.5, 4.0, 5.0, 6.3, 8.0, 10.0, 12.5, and 16 kHz.
Compression
Compression reduces the volume of loud sounds and amplifies soft sounds. It also limits loud sounds to a lower level, protecting sensitive hearing. Compression is typically used for voice and hearing assistance applications for a listener who has difficulty hearing the quiet sounds of an audio broadcast.
For listening to music programs, concerts, etc., lower compression ratios or no compression is generally used. The WaveCAST has three selectable modes of compression: 1:1 (compression off), 1.5:1 (low compression) or 2:1 (high compression).
For applications such as music and voice, where high audio quality is desirable, 1:1 is the recommended mode of operation. For hearing assistance or applications where the transmitted message is critical for listening, 1.5:1 or 2:1 is recommended.
NOTE: The WaveCAST is shipped from the factory at a 1:1 compression ratio (no compression).
NOTE: Some hearing impaired people cannot tolerate as loud of a sound as those with normal hearing. Using compression can help protect those users. However, compression also can make audio sound flat. Only use compression when it is the best choice for the listeners.
Headphone Volume
The headphone volume level can be increased or decreased by using the Headphone Volume setting in the menu.
Other Preferences
The Preferences Settings provide the ability to change the Screen Time-Out, User-Entered Description, or Restore Factory Default Settings.
Screen Time-Out
The Screen Time-Out setting determines how long the transmitter displays the screen saver. The transmitter waits for 10 minutes, after no front panel button pushes, then displays the screen saver. After displaying the screen saver for the period of time set with the Screen Time-Out Setting, the transmitter display will shut off to conserve energy.
This feature is not available on the web interface.
User-Entered Description
The Description field allows the user to easily identify the transmitter. This typically comes into play when multiple transmitters need to be distinguished from one from another. The description appears on the front main info screen, and also on the web page. In a rack, all the user has to do is activate the main info screen with a touch of any button on the front, and the description is displayed as one of the fields on the main info screen.
The description can only be edited from the web interface.
Restore Defaults
The Restore Defaults action will restore the transmitter to it’s original factory settings. Restoring defaults from the front panel of the WaveCAST will reset all settings.
Restoring defaults from the web page will reset all settings except Network and Dante connectivity settings (IP Address, Subnet Mask, IP Address Mode, and Web Password). This maintains connectivity between the Web Page and the WaveCAST, as well as the optional Dante source, after the WaveCAST reboots.
In the web interface, this feature is under the Admin menu. On the front panel menu, it is under Preferences.
Network Configuration
Network Settings can only be edited from the web interface. An IP address will be automatically assigned to the WaveCAST once an Ethernet cable has been connected to the device and network connection found. Additional configuration would need to be made through the web interface.
Adjusting Network Settings
The Network Settings screen where the IP Address Mode (Static or DHCP), the IP Address, and Subnet Mask are set via the web interface. See “Network Settings Page” on page 16 for details on how to use the web interface.
IP Address Mode Static or DHCP
IP Address If the IP Address Mode is set to Static, this is where the IP Address is manually entered
Subnet Mask If the IP Address Mode is set to Static, this is where the Subnet Mask is manually entered
DHCP IP Addresses are automatically created, and is usually preferred to a manual static IP address. To set up a static IP Address:

1. Determine an appropriate static IP address for the WaveCAST.
   a. If someone set up your network, they may be able to help you determine an appropriate IP address (i.e. network system administrator).
   b. There should be no other device having this same address on the network.
   c. This will be an address on the same subnet as the router.
   For example, if the router’s address is 192.168.1.100, the first three sets of numbers will be the same (i.e. 192.168.1), and the last number will be the number you determine for the WaveCAST (i.e. .You can choose another number instead of .100).
   When you determine this address, remember or write it down. You will need it for a later step.

2. Set the Static IP Address for the WaveCAST by using the controls on the front of the WaveCAST.
   a. Enter the IP Address you determined earlier. (When entering/saving the new address, the WaveCAST will automatically change its IP Address Mode to STATIC)
   b. All settings in the WaveCAST take place immediately (they change when saved).

Dante Settings
Some Dante settings can be viewed through the web interface, but must be configured through the Dante system, not the WaveCAST. See “Network Settings Page” on page 16 for details on how to use the web interface. See your Dante device manual for information on setting up and working with your Dante network.
The Dante settings will only show up in the menu if the optional Dante feature is installed (WaveCAST D). It will not be present for other models.
The WaveCAST cannot provide Dante information until a physical connection to the Dante network is established through the Dante port on the back panel.

Web Control Interface

The WaveCAST provides a web interface to manage the device settings. These web pages can be accessed over either a hardwired or wireless network connection with most modern internet browsers.
Changes take effect when applied or saved. Any updates made through the front panel will show up on the web interface once the current page has been navigated away from, either by refreshing the page or going to a new page.

1. Open the web browser of your choice.
2. In the address bar of the browser, type in the IP address of the WaveCAST and hit Enter.
3. You should see the Login Page of the WaveCAST.
   • If you only see a page asking for a firmware update, your device may have been corrupted. See “Website problems” on page 19

Login Page

Check with your system administrator for the most recent login credentials.

Audio Settings Page
The Audio Settings page displays all current audio settings, as well as corresponding WaveCAST web-based controls. It is the first page to appear when logging into the website.
An audio monitor is visible at the top of the page. It is for informational purposes only, and does not set any settings.
Note: Network speed can affect the audio monitor updating and web page performance.
The transmitter information displays which device is being edited. If needed, the description can be adjusted on the Preference page.
Audio Input Gain is the increase in audio volume. It can be incremented one dB at a time.
The audio input source is the audio source that will be broadcast over the WaveCAST.
Audio Presets adjust the sound to specific settings to improve the audio quality depending on if you are broadcasting audio that is primarily voice, music, or for an audience requiring hearing assistance. The audio settings can also be manually adjusted in the custom presets section.
See “Audio Settings” on page 10 for more details on adjusting any of these settings.

Preferences Page
The Preferences page displays user preferences that can be tailored to each WaveCAST system.
The description sets the name of the device, which may be used to uniquely identify the device without referring to the IP address.
Other features may be available in different models of the WaveCAST, such as systems with Dante.

Network Settings Page
The Network Settings page displays network and Dante connectivity settings. Typically these are not needed after initial installation.
Changing a static IP address or subnet will not instantly take place. The changed IP address or subnet will only take affect once the device is rebooted. This can be done manually or from the Admin menu.
Note: If the IP address or subnet of the device was changed and the device is being rebooted, the website may not be available at the same URL location. Take note of the network information before rebooting the device.
Under Advanced Options, several settings for device performance can be adjusted.
TTL can be modified if there is a need to adjust the audio latency. The recommended setting for the least latency is 1, but it can be set up to 31. This setting should not be adjusted without proper consideration for your system setup.
Secure Mode can be enabled or disabled, and a 6-digit PIN number can be assigned. If enabled, users will need to use this PIN to log on to the audio stream. Users attempting to listen to the stream without the PIN will be unable to do so.
Audio TX Mode determines if the device is broadcasting in unicast mode or multicast most.
If the device is broadcasting in multicast mode, a multicast address can be automatically assigned. If a specific multicast address is required, the device administrator can enter the desired multicast address.
If available, Dante information will be displayed at the bottom of the page. This information cannot be edited via the WaveCAST and should be edited via your Dante or other audio setup.
Additional networking information is described in “Adjusting Network Settings” on page 12.

Upload Image
An image can be uploaded that will display for any users listening using the WaveCAST app. This image can be used to easily distinguish the content of your audio broadcast. The image must be under 128kB and be in PNG or JPG format.
The image can be replace at any time. To completely remove the image, the device must be reset via the front panel menu.

Administration Page
The Admin page displays administrative controls that can be used for remote site troubleshooting purposes.
The login username and password for the website can be set from this screen. If the username or password is ever forgotten, it can be restored to its default value by restoring defaults via the front panel menu.
Limited Restore Defaults on the web interface will reset the devices settings that will not affect the website connectivity. Using the limited restore defaults from the web interface will not reset the username or password. For a full reset, the reset will need to be performed via the front panel of the device.

• The audio gain control may be set incorrectly on the transmitter. Correct the Audio Gain control setting by adjusting it until the sound level peaks between 0 and 6 dB.
• It could be that the audio input is not configured for the audio source being used. If not, correct the setting of the Audio Source control menu. See “Audio Settings” on page 10.
• Some users may not be helped by this system. Severe hearing loss may require using the system with a T-coil and personal hearing aid rather than headphones. Some phones and tablets have the ability to broadcast to a T-coil; research the phone model to see if this is an option.

Users complain of too much noise during soft audio. Dynamic range of music reduced too greatly.

• The device could be set for High Compression (2:1) when Reduced Compression (1.5:1) or No Compression (1:1) would be more suitable, given the program material. If so, set the Compression Ratio to 1.5:1 or 1:1 and see if this reduces the noise. See “Audio Settings” on page 10.
  Buzz in other equipment when transmitter is on or off

• This is likely caused by incorrect audio connections, a ground loop, or defective equipment. To remedy, use proper audio wiring practice to make connections.

• Make certain the transmitter chassis is connected to the equipment cabinet rails. Buzz/hum in system may be experienced when the WaveCAST chassis is insufficiently grounded. In this case, install a ground wire to the WaveCAST chassis and terminate to a verified ground source.

Device is not working over the hardwired Ethernet network
Note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself.
The following steps are things you can try on a small, non-managed network.
In this situation you have to check the entire signal path between the control device (laptop or desktop computer) and the WaveCAST. You can save some time by pinging the router and WaveCAST. Pinging allows you to verify the wiring path without physically having to trace the wires themselves.

1. In order to perform these steps you will need the IP address of the WaveCAST and the router. You can find the IP address of the WaveCAST via the menu on the front screen of the device.

2. Make sure the WaveCAST, Router, and any other devices that may be needed (such as an Ethernet switch) are all connected and powered on. You can save time tracing wiring/hardware paths with these next three steps:
   1. Open a CMD window on the computer. (For example, on Windows 10 computers, in the search box, type “CMD”. A black box should come up and the cursor will be blinking.)
   2. Type “ping” followed by a space, followed by the IP address of the WaveCAST, and hit Enter. If you see a “reply from…[IP address]” this means the hardwired Ethernet path is OK. If you see “request timed-out”, there is most- likely a break in the wiring path between the computer and the WaveCAST.

3. Try pinging the IP address of the router. If you can get a “reply from…” the router, but not the WaveCAST, the problem is either in the wiring between the router and WaveCAST, or the WaveCAST itself could be malfunctioning.

4. Check all of the wiring between the computer and the WaveCAST. Make sure every device in the signal path is plugged in, connected, and powered on. Unplug and plug back in firmly all Ethernet cables in the path between the computer and the WaveCAST. If you find one that was loose, plug it in and test the device connection again. If none are loose, you could also replace Ethernet cables.
   Note: When checking connections, make sure the WaveCAST Ethernet cable is plugged into one of the LAN ports on the router, not the WAN port.

5. If no loose cables were found, try re-booting in this order
   1. the router
   2. the computer
   3. the WaveCAST (turn it off for 10 seconds then turn it back on)Wait at least two full minutes for the WaveCAST to re-establish itself on the network. Then try testing the connection again.
   4. Once you have verified that you can ping the WaveCAST from the computer, open an internet browser on the computer. Type the IP address of the WaveCAST into the address bar of the Internet browser.
   5. Verify the connection by changing a setting on the WaveCAST through the internet browser. If you can change settings and get feedback on the web page (or verify the change on the front display of the WaveCAST), you are now connected to the WaveCAST.

6. If you can make changes to the WaveCAST initially, but then lose that ability (get disconnected), you may have to look at network issues such as IP address conflicts, power issues, or even settings in the router.

7. You can try restoring the WaveCAST to factory settings. This will clear out any changes and allow you to start clean.

8. Try directly connecting the WaveCAST’s Ethernet cable to a PC to verify that the WaveCAST and Ethernet cable are operational.

9. If you have tried all of these steps and still can’t connect, call Williams AV for additional troubleshooting help. Note that Williams AV cannot help in all cases, as there are many variables within networks.

Device is not working over Wi-Fi
Note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself.
If you don’t have a system administrator, the following steps are things you can try on a small, non-managed network.
This situation is most often caused by the mobile device losing connection to the router when the Wi-Fi on the mobile device has been turned off (or the Wi- Fi reception is unstable).

1. In order to perform these steps you will need the SSID of the router, the router Wi-Fi connection password, and the IP address of the WaveCAST. You can find the IP address of the WaveCAST by going into the Menu on the WaveCAST itself (using the front buttons and display).

2. Make sure the WaveCAST and router are both ON.

3. Make sure the Ethernet cable going to the WaveCAST is plugged into one of the LAN ports on the router (not the WAN port).

4. Is the mobile device connected to the router? On the mobile device, go into the Wi-Fi Settings, and make sure Wi-Fi is turned on or enabled. More than one router may show up in the list of possible connections, depending upon how many routers are nearby. If you don’t see the router that is connected to the WaveCAST in the list, make sure the router is on and broadcasting it’s SSID.

5. If you see the desired router SSID in the list, connect to it by clicking on it. Usually there is a check mark or some other indication of which router/SSID you are connected to. You may need to enter the Wi-Fi password/passkey to the router to connect to it.

6. Once you have verified that you have connected the mobile device to the router, exit the Wi-Fi settings on the mobile device (without shutting off the Wi-Fi) and open an internet browser. Type the IP address of the WaveCAST into the address bar of the Internet browser and hit the Enter key. You should see the WaveCAST login web page come up.

7. Verify the connection by changing a setting on the WaveCAST through the internet browser. f you can change settings and get feedback on the web page (or verify the change on the front display of the WaveCAST), you are now connected to and controlling the WaveCAST.

8. Try re-booting in this order
   1. the router
   2. the computer
   3. the WaveCAST (turn it off for 10 seconds then turn it back on)
   Wait at least two full minutes for the WaveCAST to re-establish itself on the network. Then try testing the connection again.
   4. If you can make changes to the WaveCAST initially, but then lose that ability (get disconnected), you may have to look at deeper network issues such as IP address conflicts, power issues, or even settings in the router.
   5. If there is interference, or low Wi-Fi signal on the mobile device, try moving the router to a better location.
   6. Some mobile devices have known issues with certain routers. To fix this, you can investigate updating the operating system on the mobile device. Try a different mobile device just to verify that ANY wireless device can connect. If you can get one device connected, but not another, chances are the device that cannot connect has issues. A different brand/model of router may also fix the problem with certain devices not connecting.
   7. You can try connecting a computer directly to the WaveCAST with a standard Ethernet cable to verify that the Ethernet connection on the WaveCAST is working. Once this has been verified you can place the WaveCAST back on the network and begin troubleshooting back to the mobile Wi-Fi device.
   8. Try connecting to the WaveCAST using Wi-Fi on a laptop, rather than a mobile device, to verify that the mobile device is/is not the problem. If you can connect with a laptop, check the Wi-Fi settings on the mobile device and make sure Wi-Fi is turned On.

9. You can try restoring the WaveCAST to factory settings. This will clear out any changes and allow you to start clean.

10. If you have tried all of these steps and still can’t connect, call Williams AV for additional troubleshooting help. Note that Williams AV cannot help in all cases, as there are many variables within networks.
