Software installation

The HDMI distribution kit features video control software that helps you manage your IP video distribution and video wall configuration. The software is available on iOS for your iPhone or iPad, Android™ for your smartphone or tablet, and for the Google Chrome™ browser.

Visit http://www.StarTech.com/ST12MHDLAN4K, using the device you intend to install software on.
Under the overview tab, select the link for the store that corresponds with your device.

Select the option to download and install the software from the store page.

Open the software, to verify that it has installed correctly.

Software operation

Connecting your transmitters and receivers to the software

Note: To ensure the application functions properly, your router must support IGMP snooping. Please refer to your network switch or router documentation to ensure IGMP snooping is supported and enabled.

Ensure your computer, smartphone or tablet that the software has been installed on is connected to the same network as your transmitter(s) and receiver(s), and launch the application.
Once launched, the application will open on the Devices tab, and will automatically search for transmitters and receivers on your network and list them within the Devices tab.

Note: you can re-initiate the device search, by selecting the refresh button in the top right-hand corner of the Devices tab.

By default, each video device will have an IP address in the range of 169.254.x.x with a subnet mask of 255.255.0.0.
Each transmitter and receiver must have an IP address in the same range, and have an identical subnet mask as each other, and the tablet, smartphone or computer you have the software installed on.
For example: If your transmitter has an IP address of 169.254.10.10 with a
subnet mask of 255.255.0.0.
You must ensure the tablet, smartphone or computer you have the software installed on and each receiver has an IP address that starts with 169.254.x.x (with a varying last two digits represented here by xx) and a subnet mask of 255.255.0.0.

**To adjust the IP address and subnet mask of your transmitter(s) and

a.** Select the transmitter or receiver you’d like to adjust from the Devices tab.

b. Click the edit Icon listed in the IP address section.
c. Select Static IP and type an IP address and mask for the device.

Or
Select DHCP and your network automatically assign an IP address and mask tofor the device in the range of the rest of your network devices.

Note: DHCP must be enabled on your network to automatically assign an IP address and mask in that range.

**Switching your remote displays between video sources

**

Once the application is launched, select the Switches tab.
A list of each connected receiver will be displayed with all available transmitters displayed beside them. The transmitter that is currently selected for each receiver will be highlighted in yellow.

Note: if the receiver is part of a video wall it will be indicated with a button that lists the wall configuration and the location of the receiver.

To assign a video source, or change your video source, select the transmitter listed next to your receiver that you’d like to display.
The transmitter will turn yellow and your video source will switch on the remote display.
Note: If a receiver that was part of a video wall configuration is altered, that display will no longer be part of the video wall configuration.

Configuring your remote displays for a video wall application

Once the application is launched, select the Walls tab.
Select the + icon to launch a wizard that will walk you through your video wall creation.

No Walls have been created on this device.
To create a wall , press the +icon above.

The first page in the wizard enables you to specify the walls name as well as the number of rows and columns you would like to use in your video wall. Each row and column will represent a display in your video wall. Type your preferred name and specify the number of rows and columns, then click next.

Note: a Wall Name will be listed by default, once you type a new name the default name will be overwritten.

The next page in the wizard will create an example of the video wall with the number of rows and columns you specified.

You will need to use this example to specify which receivers are represented
within your video wall configuration. Select the receiver from the video wall
example to display a list of all connected receivers, then choose the receiver that corresponds with the proper location within your video wall configuration.

Note: If you would like to see the receiver device name on each screen, so you can easily identify which display is connected to each receiver, please select the show device names on screen switch. This can be deactivated once you have identified your displays.

(Optional) If the displays in your video wall configuration have large bezels or
empty space between them, you can scale the image on the displays to create a more natural, seamless look by specifying the bezel compensation. Click the Bezel Compensation button to open the window.

On the bezel compensation window, enter the following measurements in millimeters (mm): screen width of each display (ScreenX), screen height of each display (ScreenY), total width of each display (DisplayX) and total height of each display (DisplayY). Then click the Save button.

The wizard is now complete and your created video wall configuration will appear
on the Walls tab.
You can select or switch your video source for each created video wall configuration clicking transmitters listed below each created video wall configuration.

Notes:

The display indicators will show the status of the current wall. Blue indicates that the display is active, Grey indicates it is being used for another wall or switch.
You can adjust the settings defined for each video wall configuration or delete your video wall configuration by clicking the arrow next to each video wall.

Advanced operation and help

You can access the software menu from any screen by clicking the menu icon in the
top right-hand corner of the application.

Help:
Lists information and walk-throughs regarding operation of the application.
Device Search Mode:
Enables you to define your preferred method of transmitter and receiver identification
over your network that the software uses. You can choose between two methods of identification: Multicast DNS or Target IP for your transmitters and receivers.

Multicast DNS: is the default setting and will search automatically for devices over
the network.
Target IP: is an advanced setting that enables you to specify an IP address that
the remote devices are set to in order for the software to identify them. This is a
good option if you’d like multiple set ups with different displays and transmitters on different subnets and IP address ranges.

Clear All Settings:
Restores your software to default settings.
Demo Mode:
Creates a virtual environment with multiple transmitters and receivers that enables
you to configure a virtual setup without connected transmitters and receivers to test the functionality of the software.
