4.2.1.2 COM2
The PPC2 AF COM2 RS232 interface is located on the back of the unit. It can be
used to allow the Host computer to communicate with another device through the
PPC2 AF. This allows the user to use one Host COM port to communicate with
the PPC2 AF and an additional RS-232 device. Refer to the “#” remote
command for details.
It is a 9 pin female DB-9F connector configured as a DTE device. Data is
transmitted out of the unit using pin 3, and is received on pin 2. This allows a
normal “pin to pin” DB-9M to DB-9F RS232 cable to be used to connect to a DCE
device. Handshaking is not required or supported.
