Caution: Note that RTS and CTS signals are not active in RS-422 and RS-

Once you make a cable for communicating with COM2, you will need to set
the COM2 DIP switch settings.
COM2 is set to the RS-485 protocol by default. To change COM2 to the RS-
232 or RS-422 protocol, you must change the COM2 DIP switch settings.
The DIP switch for COM2 is located on the side of the PA PowerStation, as
shown in Figure 3-4 for the 15” unit.
