2.4.2 Connecting to NMEA 0183 Interface
The Maretron SSC300 provides a connection to an NMEA 0183 interface through an eight pin
male connector (Figure 6). You connect the SSC300 to an NMEA 0183 network using the
optional MARE-004-1M-7 Maretron 10 meter cable by connecting the female end of the cable to
the SSC300 (note the key on the male connector and keyway on the female connector). Be sure
the cable is connected securely and that the collar on the cable connector is tightened firmly.

Connect the other end of the cable consisting of individual wires using recommended practices
for installing NMEA 0183 products. Please note that NMEA 0183 does not have a standard for
connectors and the customer/installer should contact the manufacturer of the equipment to
which the SSC300 is being connected for information on how to properly connect the device to
the SSC300. The individual wires found within the cable have the following color coding.
Wire Color Name Description
Gray TXA Transmit Differential Output A Signal
Brown TXB Transmit Differential Output B Signal
Blue RXA Receive Differential Input A Signal
White RXB Receive Differential Input B Signal

2.4.2.1 Power Connections
If the NMEA 2000
®
interface is connected, power is supplied to the SSC300 through the NMEA
2000
®
network connection.
If only the NMEA 0183 interface is used, power connections must be made via the NMEA
2000
®
/Power connector. Using the optional FA-CF-ST Micro Field Attachable Connector
(Female), connect a cable containing two power wires (not included) to pins 2 and 3 of the field
attachable connector (only the two power pins need be connected) as shown in Figure 4 on
