  • Page 3: Overview

    This document provides a brief guide to connecting and configuring the necessary components for using NMEA 0183 devices with the FLIR camera. The user should have a basic understanding of the installation of these devices and the cables and interconnections between them. Complete details about the NMEA communications, configuration of cameras, IP networks and so on are generally beyond the scope of this document.

  • Page 4: References

    It is common to integrate a FLIR camera with other devices that use NMEA 0183 communications. The camera, as a listener device, can receive position data from a GPS and compass that allows it to calculate its position relative to other objects such as radar tracks.

  • Page 5: System Connections

    The Ethernet interface on the camera is a PSE device. In a simple installation, the FLIR JCU is connected directly to the camera Ethernet and draws its power from the camera. In this example, a PoE switch is used instead to power the JCU and interconnect it with the camera.

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Multiple Nexus Servers By default, the MV cameras have a configuration that includes two Nexus Servers: one for the camera and one for a radar. The Camera Server controls and monitors the various devices in the camera, such as the pan/tilt platform, the IR thermal cameras, the DLTV and LLTV visible cameras and other devices.

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Geo-Referencing of the Sensors The Camera Server and the Radar Server can each have a georeference location. When the camera is installed on a vessel, the location information can come from a GPS and gyrocompass and the information is available as NMEA data directly from those devices or through the radar device.

  • Page 8: Radar Communications

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Radar Communications The radar device communicates NMEA 0183 sentences over a serial connection. For the first example, a Moxa Nport 5150 server serial port is connected to the serial interface of the radar, and allows the NMEA data to then be sent via the Ethernet over the network to the camera.

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Moxa NPort Server In order to use the NPort server on the network, it will need to have an IP address that is compatible with the IP address of the camera, so it is likely it will need to be changed. In this example the NPort is assigned IP address 192.168.250.97.
  • Page 10 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Select the Operating Mode tab to set up the UDP Terminal. Select the Modify checkbox and then the Settings button to change the UDP Mode settings.
  • Page 11 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Set the UDP Mode Settings Destination Begin and End IP addresses to the IP address of the camera, and set the port number to 10001. These correspond to the UDP Terminal that is configured in the Radar Server.
  • Page 12 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Once the UDP Mode is set up, it is possible to use the Port Monitor feature to confirm if the radar data is received by the NPort server. Select the Port Monitor Option, then select “Add” at the top. Once the NPort device is displayed, select the checkbox next to it and click OK.
  • Page 13 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Use the Port Monitor settings (right click on one of the column headings) to add a column that displays the number of transmitted and received packets – for example, “Tx/Rx after Mon”. Select the “Go”...

  • Page 14: Radar Server Configuration Changes

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Radar Server Configuration Changes Warning: do not make any changes to the configuration file other than the changes listed here in this document. Open the server.ini configuration file with a text editor. Some parts of the file contain parameters that relate to Sensor 0 (the Camera Server) and some contain parameters that relate to Sensor 1 (the Radar Server).
  • Page 15 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Use the joystick to move down to “Special Modes”, and select that option. In the Special Modes Menu, select “NMEA Modes”. In the NMEA Modes Menu, select the “Track NMEA Mode: Disabled” line to enable tracking. Confirm the camera responds to radar tracks.

  • Page 16: Multiple Nmea Devices

    432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note Multiple NMEA Devices In the next example, multiple NMEA talker devices are able to send NMEA sentences to the camera. In this case, the GPS, gyrocompass, and radar are connected to an NMEA multiplexer (also known as mux), and the output port of the NMEA multiplexer is connected to serial port of the Moxa NPort server used in the previous example.
  • Page 17 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note An alternative solution allows provides the same type of connectivity and combines the Serial Ethernet server and the NMEA Multiplexer into a single device. The ShipModul MiniPlex-2E operates on 12-24VDC rather than PoE, and can connect up to 4 NMEA talkers. Connect the ShipModul mux to power and to the switch.
  • Page 18 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note The ShipModul uses port number 10110, which is a registered port for NMEA data. Therefore the UDP Terminal of the Radar Server configuration is also set up to use port 10110. Open the camera server.ini configuration file with a text editor, as in the first example.
  • Page 19 432-0007-00-28-en-US v100 Integration with NMEA Devices – Application Note In the ShipModul software, select the Connect button to connect to the MiniPlex mux. Verify if the mux is receiving NMEA data from the devices. The image above shows $GPGLL sentences from the GPS and $RATTM sentences from the radar.

  • Page 20: Troubleshooting

    Integration with NMEA Devices – Application Note Troubleshooting The FLIR Sensors Manager software is a convenient tool for monitoring and troubleshooting the camera and the Radar Server. If it has not already been done, install and run FSM, and use Setup > Discovery to add the Camera and Radar Servers to the list of Active Sensors.

    Be sure to allow time for the camera and the display to fully boot up and for the MFD to “discover” the camera. When the camera is first powered on, it will temporarily display the FLIR splash screen on the video for a few seconds, and then the video will stop again until the JCU or MFD connects to the camera and brings it out of Standby mode.
