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. The NPort connects to the network
through the same PoE switch as the JCU.
Refer to the manufacturer’s documentation for configuration and wiring information about the serial ports
on the NPort server and on the radar. Specifically, ensure that both sides use the same signalling standard
(RS422 or RS232), baud rate, and so on. Ensure the transmitted signals from the radar go to the receive
side on the NPort.
Since the radar does not connect directly to the camera, the camera must be able to pull in the radar data
from the network. The Radar Server makes use of a UDP Terminal to make a connection with the NPort
serial server. The Radar Server will listen for UDP communication packets (called datagrams) that are sent
to a particular port number; in this case, port number 10001 will be used. The Moxa NPort server will also
be configured to send datagrams to that same port number.
