Automation Control
Image Servers can be controlled by leading broadcast automation systems, instant replay
panels, video switchers, and many remote control devices. The Image Server accepts VDCP, Sony
BVW and Odetics commands on three 9-pin serial connectors. To provide compatibility with
simple controllers and push buttons, the server also provides six GPI (contact closure) inputs, and
six programmable-command outputs.
Remote Serial Control
The Image Server’s three 9-pin serial control ports permit independent control of its three
video channels. Each port can also respond to channel ID numbers that are equal to, or multiples
of, its base number. For example, channel 1 will also respond to 4, 7, 10, etc. This can be helpful
when an automation system needs to control a number of Image Servers at once.
The server’s multiple serial ports allow simultaneous connection of an automation
controller and a desktop editing controller. This way, one could configure an edit controller on
Channel 1 for record, playout, and editing; while an automation controller on Channel 2 manages
play-to-air operations. Alternatively, a single controller could control the operation of all Image
Server channels.
Controller Priority
Only one serial controller can control a given video channel at a time In general, the first
controller to gain control of a video channel will have exclusive command. This prevents
conflicting instructions that would cause unexpected behavior. The only exception is that the
graphic user interface can immediately take control of a channel by selecting
Local
mode in that
channel’s dialog window (by deselecting
Remote
).
External controllers are prohibited from seizing command from the GUI, the
Remote
mode
must be checked in the channel dialog window before a remote control device can communicate
with that channel.
Communication Protocol Setup
Image Servers support VDCP, Sony BVW and Odetics command protocols. Set the desired
protocol for each server serial port with the Serial Ports dialog box of the GUI, as shown in the
following illustration. From the main menu, select
Configure
, then
System
,
then the
Control
tab. Select
VDCP
, or
P2 (9-pin)
for Sony BVW / Odetics.
