PROTOCOL TRANSLATION

The Protocol Translator within Interlinear allows a remote VTR controller to use Clipbox for playback and recording.  Interlinear's Remote Port uses industry standard RS422 VTR protocol.

Operation of Interlinear Remote Port

Connect Interlinear's Remote Port to the remote VTR or edit controller with a standard VTR cable.  Use Interlinear to select the clip for the remote VTR controller to play, or set the recording parameters and duration to use if the remote controller will record on Clipbox.  Press TRANSLATOR key to enable (or disable) the remote control facility.  The TRANSLATOR key lights to indicate that the Protocol Translator is enabled.  The remote controller now has access to the selected clip for playback, and can record on Clipbox if desired.  Please note that until a clip is selected, the Protocol Translation does not reply to the remote controller.
