Discrete Remote Control Commands

The GFR-700HD can be controlled via its serial RS-232 port. The serial port can be connected to a media con- trol center, PC, or ‘dumb terminal’ via a straight-through standard 9-pin serial port cable (MALE on one end and FEMALE on the other end). When using a PC, a terminal emulator program (e.g. HyperTerminal), can be used to control the GTP-870HD. The communications parameters should be set as follows:

•9600 baud, 8 data bits, no parity, 1 stop bit, and Flow Control: Hardware.

•All serial port control commands are structured as a four byte packet or string “<SOP>, <cmd>, <data>, <EOP>”.

•SPECIAL RESERVED CHARACTERS: <SOP> Start Of Packet = 0x7B = “{“ (The Left Curly Bracket); <EOP> End Of Packet = 0x7D = “}” (The Right Curly Bracket).

•Example syntax for the Discrete Remote Control Command for ‘Main Volume UP’ expressed as a hexadecimal string: 0x7B, 0x44, 0x2B, 0x7D
