aces
4.1.4 Rx In and Tx Out connectors
The ACU has an Rx Out and a Tx In connector. Use these connectors to connect the ACU to
the modem.
4.1.5 NMEA 0183
1
connector
The ACU has an NMEA 0183 connector for the ship’s gyro.
1. Connect the pins according to the table above.
NMEA 0183
The NMEA 0183 connection supports EN 61162-1 (baud rate 4800, format 8N1) and EN
61162-2 (baud rate 38400, format 8N1). The ACU detects the baud rate automatically, you
cannot configure this interface.
