Discrete Remote Control Commands
The GTP-870HD 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
