Appendix
This chapter provides further details about the system, for example,
about the RS-422 control of the VENICE server.
A.1 RS-422 Control
The VENICE server provides one remote control port for each channel.
Its direction (In/Out, i.e. its pin-out) is determined by the selected
RS-422 mode in the VENICE client software.
For slave mode the DVS system supports the RS-422 9-pin control pro-
tocol and VDCP. When acting as a master, the DVS system uses the
RS-422 9-pin control protocol.
In case you want to control the DVS system in slave mode via RS-422,
the following specifications have to be set on the master device to en-
sure frame accurate editing:
preroll >= 1 sec.
edit lag (edit delay) 7 frames
postroll 1 sec.
