Automation Control
MAXX-1200’s serial control ports allow operation with many broadcast automation systems,
instant replay panels, video switchers, and remote control devices.
For 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 server’s three serial control ports (9-pin, EIA-422) permit independent control of its three
video channels. The following protocols are accepted:
•
VDCP
•
BVW
•
ODETICS Extensions to the BVW protocol

CH1 - Channel 1, also referred to as COM1
CH2 - Channel 2, also referred to as COM2
CH3 -
Channel 3, also referred to as COM3
With VDCP, 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 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 server channels.
It is possible for a single VDCP controller to control multiple server channels through one
physical serial port. This is up to the design of the controller; it cannot be configured in the server
if the controller does not support it. When using a single port to control more than one channel,
be sure the
Assigned Serial Ports
option is unchecked. Do not attempt to use a different serial
port to control one of the video channels that is under multichannel control.
