RS-422 Control

What is RS-422 Control?

The RS-422 standard is a serial deck control broadcast standard and has been used by
broadcasters since the early 1980s and is found on many decks, linear editors, non linear
editors and broadcast automation products. Your Blackmagic Duplicator 4K supports this
standard so can be integrated into broadcast automation, remote control systems, scheduled
recording systems and any kind of custom control you might like to design yourself.

Using an External RS-422 Controller

Your Blackmagic Duplicator 4K features an industry standard Sony(tm) compatible 'remote'
RS-422 deck control port, which has the correct pin connections for a direct connection to any
remote controller with RS-422.
You can use pre-manufactured 9 pin cables as long as each end of the cable is wired 'pin for
pin' where the same pin numbers on each end of the cable are connected together. If your
equipment is wired differently and you would like to make custom cables, please refer to the
accompanying remote input wiring diagram so you can make sure the transmit, or Tx, pins are
wired to the receive, or Rx, pins.
By connecting an external RS-422 controller to your Blackmagic Duplicator 4K, you can control
the unit remotely instead of pushing buttons locally.
1 Connect an RS-422 cable from your external controller to your Blackmagic Duplicator
4K's remote input.
2 Press the remote button marked 'REM' on your Blackmagic Duplicator 4K's control
panel to enable remote deck control.
You can now start and stop recording, or start and stop an append record with your Blackmagic
Duplicator 4K remotely. A full list of supported RS-422 commands are provided in the following
section named 'supported RS-422 commands'.
