Communications Module

The communications module is the "brains" of the vehicle and coordinates vehicle control systems and provides data paths for sensors and accessories.

9 Pin Interface Connectors

Pin Male Connector (port 1) Female Connectors (ports 2-6)
1 NC ETH_RXP +
2 NC ETH_RXP -
3 24 V DC + 24 V DC +
4 M100 EOP + ETH_TXP +
5 GND GND
6 M100 EOP - ETH_TXP -
7 RS-485 A RS-485 A
8 RS-485 B RS-485 B
9 12 V DC + 12 V DC +

Power is rated at 300 Watts for the 24 Volt circuit and 120 Watts for the 12 Volt circuit. This is the total output of the internal DC/DC converters and is divided across all connections as demanded by each externally connected device. Each connector pin is rated to 5 Amps, which should not be exceeded. For any one connector, the maximum Watts should not exceed 120 Watts for the 24 Volt circuit and 60 Watts for the 12 Volt circuit.
