Controlling a Video Deck
Avid editing systems provide video deck control through a serial control connector on most
decks. You can control a single deck by using an RS-232 to RS-422 serial adapter. The
adapter converts an RS-232 signal to an RS-422 signal to control a VTR from your Avid
editing workstation. An optional RS-232 to RS-422 serial adapter kit is available through
Avid.
The adapters include two diagnostic LEDs (power and data). The power LED glows steadily
when the adapter is receiving adequate power through the serial port. The data LED flashes
whenever data is being transmitted or received. This helps you confirm that the serial port is
active.
The optional serial adapter kit that contains the following:
• An RS-232 to RS-422 serial adapter
• Two serial cables with 9-pin male connectors at both ends
To connect a single deck to your system:
1. Locate the serial adapter kit.
2. Attach one end of a 9-pin cable to the end of the serial adapter labeled RS-232.
3. Attach the other end of the 9-pin cable to the serial port on the Avid editing system or to
the serial connector of the USB-to-serial adapter.

When you attach the cable to the serial port on the PC, note if you are using the COM1 or
COM2 serial port. You need to select the same port in the Avid editing application.
