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.

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