Pin assignment of port C
Port C is an RS232 interface
Pin assignment of port C
Legend:
1) The pin is switched in parallel with pin 4 by port B. Total loading is 600mA.
When switched on, the terminal routes current to the farm equipment that is connected via the RS232 connector. The voltage of the RS232 connector is dependent on the operating voltage of the terminal.
When connected to a 12 V battery, the terminal will transfer approx. 11.3 V to the connected equipment.
When connected to a 24 V battery, the terminal will transfer approx. 23.3 V to the connected equipment.
The use of a GPS Receiver only requires the signals RxD and TxD as well as GND.
