W2K-1 Intro & Features

The W2K-1 is a compact and low-power NMEA 2000 to Wi-Fi Gateway with data logging. It transfers data from an NMEA 2000 backbone to any compatible device (e.g. laptop, tablet or smartphone) connected to it via Wi-Fi.
It has built-in conversion of NMEA 2000 messages into NMEA 0183 sentences thus allowing a wide variety of vessel data (e.g. position, speed, course, wind speed, depth, engine data, AIS messages etc.) to be shared with NMEA 0183 compatible software applications running on connected devices.
All the data received can be logged to its internal micro SD card for later downloading to use for analysing the voyage. This is very useful for analysing race data, generating logbooks, diagnosing problems or even sharing your voyage details. Approximately 16 days* of data can be stored on the pre- installed industrial grade micro SD card, which can be upgraded should the user require more storage.
The W2K-1 has the legendary Actisense “Reliability Built In” along with useful diagnostic LEDs, internal antenna, enhanced password security, full certification and all packaged in an extremely rugged IP67 case.

• NMEA 2000 to Wi-Fi Gateway and data logging in one device

NMEA 2000 Network Basics

Minimum Requirements
A correctly powered and terminated NMEA 2000 network is required before installing the W2K-1. The minimum requirements for any NMEA 2000 network are:
Either
An Actisense SBN-1/2 (a NMEA 2000 self-contained network)
Or
Power insertion point, or `Power T’ (Actisense A2K-MPT-2)
2x T-Pieces (Actisense A2K-T-MFF)
2x Termination resistors. One at either end of the NMEA 2000 Network (Actisense A2K-TER)

And
2x NMEA 2000 Devices (The W2K-1 is one of these devices)

NMEA 2000 Network Cable Limitations

Cable Type| Max Length| Max Amp| Power Pair| Data Pair
---|---|---|---|---
Drop Cable| 6m| | |
Sum of all drop cables| 78m| | |
Micro backbone (terminator to terminator)| 100m| 3 Amps| 22 AWG| 24 AWG
Mid backbone (terminator to terminator)| 250m| 4 Amps| 18 AWG| 20 AWG
Mini backbone (terminator to terminator)| 250m| 8 Amps| 15 AWG| 18 AWG

Powering the W2K-1
The W2K-1 receives its power from the NMEA 2000 backbone and is compatible with 12VDC and 24VDC supplies typically using 70mA (2 LEN) at 12 VDC. Once powered, the LEDs inside the case will illuminate.
Minimum NMEA 2000 ® Micro Cable Network (2 devices)

All wiring should be in accordance with the regional code of practice for installations.
Refer to the ‘Troubleshooting’ section of this manual for a full description of the W2K-1 LED behaviour.
The W2K-1 has been designed to connect directly to an Actisense “T” piece (A2K-T-MFF) without the need for a drop cable, however a drop cable (A2K-TDC) can be used to improve the installation.
The maximum length for any instrument drop from the NMEA 2000 backbone is 6 metres. The NMEA 2000 network should always be fused according to the maximum capacity of the cable used. See `NMEA 2000 Network Cable Limitations’ above.

The W2K-1 measures the bus voltage at its micro connector and reports this via:

• The NMEA 2000 bus using PGN : 127508 : Battery Status.
• The Web Interface status page
• The Actisense-i gauge and graph

Set Up
The W2K-1 has a built in, web based configuration tool compatible with the latest versions of all popular web browsers. To access it, a Wi-Fi connection is required between a compatible device and the W2K-1.

Connecting to Wi-Fi
The initial connection to a W2K-1 must use the Access Point Method, and it will broadcast it’s SSID as “w2k-”. This ensures that, by default, every W2K-1 has a unique Access Point.
The serial number of your device can be found printed on labels, both on the front and rear of the case. (e.g. If your serial number is 123456, then your the SSID for your W2K-1 will be w2k-123456) The default Wi-Fi password is printed on the rear of the device.
Note : the password is 8 characters consisting of 1…9, A…Z (excluding I & O), a…z (excluding l) A spare password sticker is also provided which can be kept in a safe & convenient location to avoid having to physically access the W2K-1.(e.g. if more devices need to be connected to the W2K-1)
This Wi-Fi password can be changed at any time, but if it’s lost or forgotten, the W2K-1 password can be reset back to its default after gaining physical access to the unit, see Password Recovery.
The W2K-1’s SSID will be visible using the network settings (show available networks) of your PC, or usually under settings / connections / Wi-Fi on your mobile device. Selecting it will prompt a connection and request the user to enter the Wi-Fi password listed on the rear of the device. Once the password is entered, the Wi-Fi enabled PC or device should connect within a few seconds (dependant on operating system).
Note: The connection manager will report “No Internet” which is correct as your device is now connected directly to the W2K-1 Access Point which does not provide internet access.
The W2K-1’s built-in configuration can always be accessed by typing in the IP address:192.168.4.1 into the address bar of your Wi-Fi enabled PC or devices web browser.

Wi-Fi Modes
The W2K-1 can be used in either Access Point Method or Client Method (also referred to as Station or STA mode) Both modes can also be used simultaneously.

Access Point Method
This method can also be used where other Wi-Fi devices need to connect to / exchange data with the W2K1 in the absence of an existing Wi-Fi network. The W2K-1 will, by default, use channel 1 in this mode.

Client Method
This is where the W2K-1 will become a “client” on an existing Wi-Fi enabled network, enabling the W2K-1 to connect to / exchange data with other devices connected to that existing network. The W2K-1 will switch to the Wi-Fi channel of the client network in this mode. See Wi-Fi Client settings.
Note: Log files will download faster if only a single access point is connected to the W2K-1.
The W2K-1 default channel for access point mode is channel 1, however when the W2K-1 is used in client mode, the Wi-Fi channel of the client (e.g. Wi-Fi router) will be adopted by the W2K-1 for all modes. The device which is browsing will need to re-connect to the access point or connect via the client using the client IP address. The W2K-1 remembers client status, so even on a power cycle it will then automatically join the client on its channel.

Configuring the W2K-1

Make sure you have connected the W2K-1 Access Point via Wi-Fi with your PC or device. You can now access the W2K-1 configuration page from any web browser. Enter the IP address : 192.168.4.1 into the address bar and you will be presented with the W2K-1 home page. Note: Pages which allow configuration changes are password protected and will prompt the user to “Login”. Note: The web browser will automatically test its connection to the W2K-1 and display a warning if the connection is lost.

Information Page
Use this page to access important product information such as device status, serial number, MAC address and firmware version. Client and access point status are also available from this page.

Settings Menu Page

Login Page
The default login details for the W2K-1 configuration tool are:
Username : admin Password : admin

Wi-Fi Access Point Setting
The Wi-Fi Password can be changed here. It needs to be a minimum of 8 characters, and a max of 50.

Note: If the password is forgotten, it can be re-set back to the default after gaining physical access to the unit, to remove and restore the micro SD card. See Password Recovery.
The Access Point can be set to “Hidden” in which case the SSID will not be broadcasted. If it is set to ”Hidden”, you will need to use the “join hidden network” function on your PC or device in order to connect to the W2K-1. The SSID of the W2K-1 will then need to be manually typed in when prompted.
The authentication mode can be set by “Authmode”. By default this is “WPA2-PSK”, which is supported by most modern PCs and devices.
Warning: It is NOT recommended to set this to “Open” as this will allow any Wi-Fi enabled PC or mobile device to access the W2K-1 without entering a password.
The Access Point uses Wi-Fi channel 1 be default, however when a client is joined, the Wi-Fi channel of the client will be adopted for all modes. If a user is connected to the W2K-1 Access Point and then joins a Client network, the link to the Access Point will be dropped if the Client network is set to a different Wi-Fi channel. In this case, simply reconnect to the Wi-Fi Access Point if needed, and your PC or device will adopt the correct Wi-Fi channel.
The maximum number of simultaneous connections to the Access Point is 4.

Wi-Fi Client Settings

Scan for Client networks and then either join or disconnect from these networks.
Note: The connection will be interrupted during a scan.
This page shows the current connection status and Client SSID (if connected) in the top status bar. When a Client network is joined, the Wi-Fi channel of the Client will be adopted for all modes. The W2K-1 will be issued with an IP address by the Client network, and this IP address should then be used to connect to and access the W2K-1 via the Client network.
The W2K-1 Access Point will still be active and you can find out the IP address allocated to the W2K-1 by connecting to the Access Point and entering the default IP address 192.168.4.1 in a web-browser and checking the Information Page.
Note: The W2K-1 remembers the Client’s connection details and will use those to automatically join the Client after a power cycle, or when the connection is dropped for some reason. Click the “Forget” button to remove a client’s connection details from the W2K-1’s memory.

Data Server Settings

The W2K-1 has three separate data servers – “Server 1”, “Server 2” and “Server 3” which can work concurrently and can be enabled independently. The Data Server Settings need to be configured to correspond to that of the connected application software. To configure a data server for your application, you can setup the “Protocol”, “Format”, “Direction” and “Port”. There is also an independent “Check box” which can enable or disable a data server. This will not cause the W2K-1 to forget the other settings – it is an on/off switch which will start or stop that server.

Protocol
This is the “IP” protocol. Both TCP and UDP are supported, and this should be set according to the connected applications’ capabilities. TCP is recommended as it has built-in error correction.
Note: The W2K-1 currently only supports UDP transmit, (Not UDP receive). If a client network has been joined, then UDP will be available via both client network and Access point because UDP connections only require a Port Number.

Direction
This sets whether this data server will transmit, receive, or both receive and transmit data.

Format
Several data formats are provided. If the format required for your application is not currently available, please contact Actisense support to check availability – we might already have it on our development road map or be able to add it specifically for a customer application. The current formats are:

NMEA 0183
As most applications support the NMEA 0183 format, this provides universal compatibility, however please note that this involves conversion from NMEA 2000 PGNs to NMEA 0183 sentences and not every NMEA 2000 PGN field has a corresponding NMEA 0183 sentence field. Conversions for all popular sentences and PGNs are provided, please refer to the current W2K-1 Conversion List.

ASCII RAW
This allows the W2K-1 to send and receive raw CAN packets to and from the NMEA 2000 bus. Caution should be exercised when sending unformatted CAN data to the NMEA 2000 bus. It is supported by some other manufacturers as a means for receiving and sending CAN information in its simplest “Raw” form. ASCII Raw has the advantage of being human readable.

Actisense RAW
Like ASCII raw, this format allows the W2K-1 to send and receive raw CAN packets to and from the NMEA 2000 bus. Similar caution should be exercised as for ASCII Raw when sending unformatted CAN data to the NMEA 2000 bus. This format is not currently widely supported and will be used by Actisense data logging and simulation technology in due course. For user applications, this format is more bandwidth efficient than ASCII formats and will be fully documented for use by third party software.

ASCII N2K
This is a new Actisense proprietary encoding technique for transferring complete NMEA 2000 PGNs. This format can be sent and received by the W2K-1. If viewed on “IP port monitor” software such as https://www.aggsoft.com/serial- port-monitor.htm, the N2K “PGNs” are easy to read as a scrolling text display. The advantage of this format is that all PGN data is “assembled” from the raw CAN packets into an easier to use format for user applications. This format will be fully published on the Actisense website.

Actisense N2K
For transferring complete NMEA 2000 PGNs. This format can be transmitted and received by the W2K-1.
This is a pure binary format used by the future versions of Actisense Toolkit software to allow data logging and analysis of N2K data. It is more bandwidth efficient than ASCII N2K format. This format will be fully published on the Actisense website.

Actisense NGT
This format has been in use by the Actisense NGT-1 since 2007. Currently this format can only be transmitted from the W2K-1. This is also a pure binary format encoded in the same binary format as the Actisense NGT. For software applications that have been previously designed to be compatible with the NGT-1, this format will work directly with that software. There are third- party applications which can use this NMEA 2000 binary format now.

Filtering
For an enabled data server set to use an NMEA 2000 data protocol, you may click on the ellipses icon to open the filtering options page for that particular data server. Within this page you will find a list of all available PGNs with individual check boxes to enable them. The Tx (Transmit) Rate displays (in milliseconds) either the default Tx rate of a given PGN, “non- periodical” for “triggered” PGNs, and “0” for Tx disabled PGNs.
Once configured, you may “Save” your selection to return to the Data Server page and then click “Update” to apply your settings

Port Number
By default, the W2K-1 uses Ports 60001 – 60003, but can be set to any value corresponding to that of the application software. IP Ports can be set in the range 1-65535, although ports 1-1024 should be avoided, as they are used by special internet services. Setting a data server to use those ports could result in network problems.
Note: Some applications use the default setting for NMEA 0183 over Wi-Fi as port 10110, so in this case the W2K-1 data server settings should be set to 10110. Other vendors such as Navionics use port 2000 for the default NMEA Wi- Fi gateway.
To get an application to work with the W2K-1, the IP Address of the W2K-1 (see Wi-Fi Access Point and Client Settings) and the port settings need to correspond. For UDP, often only the port number is used, and it is possible to merge data across multiple applications by sending to the same UDP port. Thus, care should be exercised, as not all data formats are compatible. The W2K-1 has been tested with many popular PC and Device applications and configuring the connection and data format is similar across the different software applications.
Below shows an example of connecting to the popular OpenCPN application.

Administration
The Admin (Login) password can be changed here to a new one that’s between 2 and 30 characters long.
If the password is mislaid or forgotten, it can be reset back to the default after gaining physical access to the unit by opening the blank end-cap and ejecting the SD card, see Password Recovery.
Warning: Actisense strongly recommends changing the default password to reduce the chance of unauthorised access to the N2K network and the vessels systems.
The W2K-1 device can be conveniently restarted by clicking the ‘Restart’ button.

Firmware Update
Upload and install new firmware from a “.zip” file. Note: Do NOT extract files prior to upload. Firmware updates in the correct ‘.zip’ file format for the W2K-1 are available at www.actisense.com. The version of firmware currently installed in the W2K-1 can be found in the “Information” menu on the W2K-1 home page.
Note: Do not disconnect the unit from the NMEA 2000 bus or remove power until the firmware update process has completed and the unit has re-booted such that the PWR LED is pulsing. See LED Behaviour. Remember, you need to re- connect to the device after the firmware upgrade.

Logging Settings
The W2K-1 ships with an internal 8GB industrial rated micro SD card specified with a C10 continuous writing speed. Enable logging of data to that SD card via the ‘Logging setup’ button. The length of time before the SD card becomes full depends on the amount of data on the NMEA 2000 network. When the SD card is full, it will begin to write over existing log files, starting with the oldest.
The amount of data which can be logged on the 8GB micro SD is dependant on exactly how “busy” the bus is. On a “busy” bus, (approximately 50% loading), the user can expect at least 6 days of continuous data logging. On a “lightly loaded” bus, (approximately 5% loading), the user can expect in excess of 30 days continuous data logging.
If the W2K-1 is restarted or power cycled, it will create a new log file and the previous log file size will be dependant on when restart occurred.
The SD Card within the W2K-1 can be replaced by one with a larger storage space, up to 128GB.
Note: A GPS source on the NMEA 2000 bus needs to be used in order to provide UTC time stamps for the log files. If no GPS is available, default date and time will be used.
Log files can be downloaded using the ‘Download logs’ button. Each file is approximately 5MB in size and multiple files or an entire directory can be selected.

Mounting the W2K-1

The W2K-1 has an internal antenna which is located on the end opposite to the NMEA 2000 connector and should not be mounted on a metal surface. To ensure best range it should be mounted vertically and located centrally on the boat as high as possible, avoiding other metallic objects.
Warning: The W2K-1 should not be mounted within 5m of a compass or operated within 20cm of a human body. To avoid potential injury it should be mounted at a height of less than 2m from floor level.

Bulkhead Mounting
The W2K-1 can be secured to a bulkhead using the two screw holes on the side of the W2K-1 shown in the picture below.

Actisense-i

Actisense-I brings valuable diagnostic capabilities to your W2K-1. Monitor various facets of your NMEA 2000 network through a neat graphic interface. Actisense will be adding new functionality regularly through firmware updates. Stay updated via our blog and social media channels.
More information about Actisense-i can be found here.

The Smart Timer sets a period between parameter value checks, if a change has been found that is greater than the Smart Threshold then the value is logged. The Maximum Timer sets a maximum period between logs. Once this period has elapsed the value is logged regardless of any change. The Maximum Timer is reset if the Smart Timer triggers a log.

Alongside the battery monitoring capability, the W2K-1 with Actisense-i will also provide you with a detailed breakdown of the complete NMEA 2000 network, including device name, source address, LEN and device info. This feature enables the user to dive deeper into the network, and acts as a high level diagnostic tool.

LED Operation and Indication Trouble Shooting Guide

LED| Colour| Normal State| Description| User action (during abnormal state)
---|---|---|---|---
PWR| Blue| Pulsing| Indicates presence of power| Check power on NMEA2000 Bus / Check Fuses / Battery Voltage
Flashing Fast| Indicates Firmware Update (Approx 4 times per second)| Do not remove power while the Firmware update is in progress
Status| Yellow| Pulsing| Indicates Wi-Fi access point is active| Confirm SSID on connecting device is correct / Confirm Client network is active /Check password is correct
Flashing| Indicates active Wi-Fi connection in either Access Point mode or Client Mode (approx once per second)
RX| Green| Flashing| Indicates data is being received on the NMEA2000 bus| Confirm there is another device transmitting on the NMEA2000 bus
TX| Amber| Flashing| Indicates data is being transmitted on the NMEA2000 bus| Confirm there are at least two NMEA2000
devices present on the bus

First level W2K-1 diagnostics / fault finding can be performed by observing the LED behaviour.
The normal behaviour of the W2K-1 LEDs is described in the table below. If the LEDs are not behaving as expected, this will indicate a fault in either the device connected to the W2K-1, the NMEA 2000 network, or the W2K-1 itself.

Some common checks to perform on the W2K-1 if the correct LED behaviour is not displayed:

• Connectors are properly inserted and secure.
• If NMEA 2000 field fit connectors are used, all pins have been wired correctly and wires are terminated firmly.
• The NMEA 2000 network is properly terminated at each end, with a 120ohm resistor. The network should not have more than two terminators. Make sure that any devices  attached to the network do not contain any internal termination resistors.
• If using a client network then UDP will only be available via the client network.
  Note: Pulsing refers to the continuous “fading” mode of the LED

Note: If the W2K-1 does not re-direct to the home page and an error message is displayed, the likely cause is that the connection to the access point has been dropped during a re-start. This is dependant on the device connecting to the W2K-1’s connection settings, and is also dependant on the operating system.
The device should be set to automatically connect to prevent this situation, thus avoiding having to manually re-connect.

Technical Support and the Returns Procedure
The first point of contact for all technical enquiries should be the vendor / supplier where the device was originally purchased. All warnings in this manual must be adhered to and installation instructions followed prior to any support requests. If the troubleshooting guide or the supplier are not able to help resolve the problem and an error persists, please visit the Actisense help centre here you will find useful articles to aid further troubleshooting and a contact form for raising a support ticket. If the Actisense support engineer concludes that the W2K-1 unit should be returned to Actisense, a ‘Return Merchandise Authorisation’ (RMA) number will be issued. The RMA number must be clearly visible on both the external packaging and any documentation returned with the product. Any returns sent without an RMA Number will incur a delay in being processed and a possible charge. Any cables originally supplied with the product are to be included in the returned box.

Password Recovery

Password Recovery
It is not possible to reset the configuration username and password using the NMEA 2000 connection, as this would require an insecure transmission of the Wi-Fi password.
For additional security, the method used to reset the password to its default requires physical access to the unit. There is no reset button provided. The SD card switch is used as a method to invoke the password reset process:

1. Switch off the unit by disconnecting the NMEA 2000 cable and open the blank end cap, as shown in the picture below.

2. As the SD card holder is a “push-push” type, push the SD card in gently and the card will then release/ eject. There is no need to completely remove the SD card from the holder.

3. Switch on the unit (by reconnecting the NMEA 2000 cable). It will detect that there is no SD card present and use the default Wi-Fi password to create its Access Point.

4. Use the default Wi-Fi password in the device(PC, Mobile phone, Tablet) to connect to the unit.

5. Refresh the web browser to see the simple “fall-back” web page.

6. On the “fall-back” web page, click the “Reset Wi-Fi settings and passwords to factory default” button.

7. The Wi-Fi password will be reset back to the unique default password shown on the unit’s underside label and on the spare password sticker supplied in the delivery box.

8. The Web Config Username and Password will also be reset back to their factory defaults (refer to ‘Login Page’ section above for details).

9. Switch off the unit again, push the SD card in until it clicks and close the blank end cap, making sure the rubber end cap seal is still fitted correctly.

10. Switch the unit back on and change the Wi-Fi password, Web Config username or Web Config password as required
