DVC-3 Data View Communications Cable

The Extron DVC-3 Data View

Communications Cable can be inserted

between two RS-232 devices for

troubleshooting and monitoring (listening

into) the serial communications between

the two devices, without interrupting the

communications. The DVC-3 Cable is

terminated with female to male 9-pin

D-sub connectors for data pass through, with two additional female 9-pin D-sub connectors

used as the monitoring connections to your PC or laptop.

Using the cables

To use the Extron DVC-3 Data View Communications

Cable, unplug the RS-232 cables between the host

and controlled unit, and connect the DVC-3 cable

labeled with “Device A” and “Device B” connectors.

Connect one of the two monitoring cables to the PC

or laptop. The monitoring cable used will depend on

the communication line intended to be monitored.

The connector labeled “A Tx/B Rx” is for monitoring

the Tx (transmit) line of device A, which is also the

Rx (receive) line of device B, and the cable labeled

“A Rx/B Tx” is for monitoring the Rx (receive) line

of device A, which is also the Tx (transmit) line

of device B.
