COM1 Serial Port Connections

The COM1 port includes connections for RS-232, RS-422 and RS-485. There is a
setup parameter that must be selected to match the hardware connection used.
This parameter controls how the transmit and receive lines are controlled.
Figure 2-21 indicates which terminal carries which signal on the COM1 port. Make
the connections as necessary.
