Appendix C — Configuring the RS-232 Interface
In order to communicate with the Electronics Module, you need a
standard serial interface card installed in your computer. If your
computer has one serial card, it is addressed as COM1. If there is a
second serial card, it is addressed as COM2. You must also have a
cable with the following connectors:
• A 9-pin male D-sub connector for the Reference Port
• A 9-pin female D-sub connector for the computer (some com-
puters use a 25-pin connector, requiring an adaptor)
