Connecting to NMEA 0183
If connecting the LT-1000 NRU to a NMEA 0183 device, then it is only required to connect the transmit part
of the NMEA 0183 wires TxD+ (Brown) and TxD- (Yellow) from the communication cable.
NOTE:
Make sure that the LT-1000 NRU is configured for the desired baud rate (4800 or 38400
baud), see DIP-switch and LEDs on page 21. Check that both the NMEA 0183 receive device
and the LT-1000 NRU have the same GND reference, as illustrated in Figure 32 and Figure 33.
IMPORTANT: It is recommended to connect the LT-1000 NRU with a balanced NMEA 0183 connection (RS-
422) as illustrated in Figure 32. An unbalanced connection (RS-232), as illustrated in Figure 33,
is less robust and should only be considered when using a short communication cable.
