2.3.2 RS232 Communication Loop
RS232 communication loop is connected with a PC for running GstGMC2.0 Graphic
Monitor Center (GMC) system PC through a DB9 port.
Recommended Wiring: Standard RS-232 interface. The 2
nd
pin (for sending data), the
3
rd
pin (for receiving data), and the 5
th
pin (ground) are connected with PC through
three-core shield cable.
Note: Wire length should be less than 15m; the screening layer and computer’s
enclosure should be earthed.
