Serial Interface Specifications COM1
Introduction
This interface is used to connect GC4000 series to remote equipment, via an RS-
232C cable. The connector used is a D-Sub 9-pin male connector.
By using a long PLC cable to connect to the panel, it is possible that the cable can
be at a different electrical potential than the panel, even if both are grounded.
The panel’s serial port is not isolated. The SG (signal ground) and the FG (functional
ground) terminals are connected inside the panel.
