3.4.3.2 PC-to-GC, Front Panel Quick and Easy RS-232
The easiest way to connect a PC to the GC Controller is with an 'off-the-shelf', straight-through serial
cable connected to the GC Controller's front panel DB-9 serial port jack.
To connect a PC to the GC Controller's front panel DB-9 serial port jack, proceed as follows:
SERIOUS PERSONAL INJURY OR DEATH POSSIBLE
Do not operate a PC in a hazardous environment. Do not make or break front panel
wiring connections in a hazardous environment. In a hazardous environment, ensure
that field connections to the Analyzer or GC Controller (including serial port) are made
through explosion-proof conduit or flameproof glands.
Failure to observe all safety precautions could result in serious injury or death.
(1) Obtain a "straight-through" serial cable:
(a) 50 feet long or less,
(b) DB-9 or DB-25 female plug at one end (for PC connection), and
(c) DB-9 male plug at the other end (for GC connection).
(d) You can buy this type of cable, with plug-ends already installed, from most computer
supply retailers, so there should be no need to custom-wire a serial cable for this type
of connection. (If, however, it is necessary to custom-wire a cable because of
circumstances, see guidelines provided in Appendix A, this manual.)
(2) Connect the serial cable's plugs to the appropriate serial port jacks at the PC and GC (front
panel). Then use the software MON2000 to "Connect" and operate the GC as needed.
