Serial Communications and Options

The rear panels of the VERTEX™ VC4 monitor allows installation of serial interface port. These ports are
designed to allow output to other devices, and two-way communication between the VERTEX™ VC4 monitor
and another device.
There are three serial interfaces available for the VERTEX™ VC4 monitor, each designed for a specific
communication application. The options are:
• RS-232 for remote bidirectional binary communication
• RS-422 for remote bidirectional binary communication
• RS-485 for remote multi-drop bidirectional binary communication via two-wire transmission
This port is a DB-9 female connector. This port is designed for bidirectional communications between the
Vertex™ VC4 and your equipment. Signals present at the port conform to RS-232, RS-422, or RS-485
specifications. This is based on which interface option was installed in your Vertex™ VC4 instrument. The pin-
out specifications for each option are as follows.
