MX610/MX612 Operator and Installation manual
NMEA 0183 output over junction box
NMEA port selection is available only when a MX61xJB junction box is detected in the N2K
network. The MX610JB has four RS-422 NMEA 0183 data ports while the MX612JB has twelve
RS-422 NMEA 0183 ports. When the MX610/MX612 CDU senses the presence of the MX61xJB
junction box, it will provide a list of port numbers based on the CDU model.
The junction box supplies the power used by devices connected to the NMEA 2000 bus. It
also provides the N2K termination when the DIP switch is set to ON.
When an MX smart antenna is connected in Ports 3 & 4 of the junction box and selected as
source of position, port 3 will be grayed out in the list. The operator will be able to control
ports 1 and 2 for the MX610JB data output and ports 1,2,5,6,7,8,9,10,11 & 12 for the MX612JB
junction box.
