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.
