Using VDCP protocol to control K2 systems

Video Disk Control Protocol (VDCP) commands are available via RS-422 serial ports.

Preroll is 1 second for mixed compression format playout. Preroll is 10 frames for same compression format playout.

The K2 AppCenter Recorder application in protocol mode allows a default bin to be assigned to each record channel.

In AppCenter, you must set a channel’s options to enable protocol control of the channel. Subsequently, when the K2 Summit system starts up, the channel is immediately available for protocol control. Manual log on is not required.

For channels in gang mode, the protocol must connect to the lowest numbered channel in the gang. This is required to support jog/shuttle of ganged channels.

Loop-play mode on the K2 Summit system is not supported under VDCP control.

The following categories of VDCP commands are not supported:

  • Deferred (Timeline) Commands --these are the basic timeline commands but use the time specified by the PRESET STANDARD TIME
  • Macro commands
  • Archive Commands
  • To control a given K2 channel, use only that channel’s specific RS-422 rear panel connector. Send the VDCP “Open Port” and “Select Port” commands only to the RS-422 connector that is associated with the channel being controlled.
