Blackmagic HyperDeck Disk Recorders 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, nonlinear editors and broadcast automation products. All current HyperDeck models support this standard so can be integrated into broadcast automation, remote control systems, editing systems and any kind of custom control you might like to design yourself.

HyperDeck Studio also supports file based commands from the Advanced Media Protocol via RS-422. This lets you control your HyperDeck with an external device using AMP commands such as adding clips to a playlist, determining the filename of the next clip, looping a single clip or timeline, or clearing a playlist.

Using an External RS-422 Controller

All current HyperDeck models feature an industry standard Sony™ compatible RS-422 deck control port, which has the correct pin connections for a direct connection to any remote controller with RS-422, for example HyperDeck Extreme Control.

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 you would like to make custom cables, please refer to the accompanying wiring diagram.

You can remotely control your HyperDeck from HyperDeck Extreme Control instead of locally pushing buttons.

Connect a video signal to your HyperDeck’s video input.
Connect an RS-422 cable from your HyperDeck Extreme Control to your HyperDeck Studio.
Enable remote control by pressing the remote button on the front control panel, or via the LCD menu in HyperDeck Studio Mini, to allow remote deck control.

You can now remotely start and stop recording and playback of your HyperDeck as well as performing other common jog and shuttle functions. The full list of supported RS-422 commands is in the following section named ‘supported RS-422 commands’.

Receive (–)	Receive (+)	Transmit (–)	Transmit (+)	Ground Pins
2	7	8	3	1, 4, 6, 9

RS-422 remote pin connections

Make sure your HyperDeck has remote set to ‘on’ in the LCD menu, or via the front panel remote button, to enable RS-422 deck control

All HyperDeck models support remote control via the RS-422 port on the rear panel
