TS-7180 COM Ports

The TS-7180 provides three standard RS-232 COM ports, and one RS-485 COM port. The latter has auto-transmit-enable. All of these ports are presented on the P5 connector. The RS-485 port has an on-board terminator that may be enabled by installing the "485" jumper.

UART	TX	RX
ttymxc1	P5-5	P5-6
ttymxc4	P5-2	P5-3
ttymxc6	P5-7	P5-8

UART	485+	485-
ttymxc3	P5-13	P5-14

Note:

The RS-232 transceiver chip on the board must be enabled before the COM ports can be used. This is done by running the command "tshwctl -a 21 -w 3"
