Additional Serial Port on CPC CardDescription The CPC-EX card contains an on-board serial port (Serial Port 2) which
can be used for Bus Monitor/ Remote Maintenance. This serial port
(labeled CN5) is located just above the LEDs on the front of the card (see
the illustration on Appendix A:-4). This additional serial port allows you to
dial directly into the system for remote maintenance, without having to
disconnect the SMDR cabling from the backplane serial port (Serial Port
1).
• Serial Port 1 (the backplane port) and Serial Port 2 have separa te controls
for baud rate, stop bit, parity, and data length
Installation Serial Port 2 requires the CPC-EX Serial Port Adapter Cable (VB-43890).
This cable connects to Serial Port 2 via a 10-pin connector, and to a
programming terminal via a DB25 connector.
