TANDBERG GW Data port Command Interface User Guide

2.Connecting to the Data port Command Interface through the RS-232 port.

The RS-232 port is a 9-pin, female, D-sub connector located on the front of the GW. The port is configured as a DCE (Data Communications Equipment). The RS-232 port is default set to 115200 baud, 8 data bits, none parity and 1 stop bit from factory. The RS-232 port is also referred to as the Data port.

2.1.Hardware and Cabling

The pin outs for the RS-232 are defined in the following table (the DTE, Data Terminal Equipment, could be a PC or other device capable of serial communication).

Pin no	Signal	Description	Direction
1	CD	Carrier detect	To DTE
2	RD	Receive data	To DTE
3	TD	Transmit data	From DTE
4	DTR	Data terminal ready	From DTE
5		Ground
6	DSR	Data set ready	To DTE
7	RTS	Ready to send	From DTE
8	CTS	Clear to send	To DTE
9	RI	Ring indicator	To DTE

NOTE! A straight through cable should be used between the TANDBERG GW’s RS-232 port and the DTE.

The figure below illustrates the recommended cable-wiring scheme for connecting the GW to a PC through RS-232.

TANDBERG GW		PC
	DCE, 9 pin	DTE, 9 pin
1	CD	1	CD
2	RD	2	RD
3	TD	3	TD
4	DTR	4	DTR
5	GND	5	GND
6	DSR	6	DSR
7	RTS	7	RTS
8	CTS	8	CTS
9	RI	9	RI

DTR and RTS are ignored. DSR, CD, and CTS are always asserted, while RI is not used.
