Controlling an External Player
The second major function of the control area of the I/O Tool – besides
reviewing an already captured clip (see chapter “Administrating Clips”
on page 3-1) – is to control an externally connected player with the
DVS system. For this the DVS software uses the RS-422 9-pin control
protocol and you can control any equipment that understands this pro-
tocol with the I/O Tool, such as telecines, VTRs or digital disk recorders.
With an externally connected player you can provide a signal at the sys-
tem’s inputs which can then be recorded by the I/O Tool (see chapter
“Capturing Clips” on page 5-1).
This chapter explains in detail the possibilities at hand to control an ex-
ternally connected player. First, the user interface of the RS-422 mode
is described, as this is the only place where you can control an external
player manually. After that follows a description of how to use the
RS-422 mode to search for video material and how to initiate a play-
out of the external player in this mode.
The parameters of the externally connected player such as pre-
roll or edit lag can be changed via device profiles in the Con-
figuration Tool (see “CLIPSTER Configurations” user guide for
more information).
