GFP-815 Serial Port
Command Set
INTRODUCTION
The Adcom GFP-815 can be controlled via the serial RS-232 port. The serial port can be connected to a sys-
tem controller, PC or ‘dumb terminal’ via a straight-through standard 9-p
in serial port cable (MALE on one end
and FEMALE on the other end). When using a PC, a terminal emulator program (e.g. HyperTerminal or Pro-
Comm), can be used to control the GFP-815.
The communications parameters should be set as follows:
9600 baud, 8 data bits, no parity, 1 stop bit and Flow Control: Hardware
