A.2.2 DB-9 Serial Port of GC to DB-25 Port of PC

To make an RS-232 serial connection between one of the DB-9 serial ports of the GC, and a PC with
DB-25 serial port, you may be able to use a "straight-through" serial cable, terminated as DB-9 male
/ DB-25 female. This will work if the PC has a male DB-25 serial port, and its pin assignments are
identical to those found on an IBM PC.
The necessary "straight-through" serial cable can be obtained from most computer products
suppliers, so custom-building a cable normally is not necessary. Wiring and signal path are
illustrated as follows (see Figure A-4).
