Automation Control
MAXX-2400HD’s serial control inputs connect 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 12 GPI
(contact closure) inputs, and 12 programmable command outputs.
Remote Serial Control
The server’s four 9-pin RS-422 serial control inputs permit control of their associated video
channels. The following serial protocols are accepted::
• VDCP
• BVW
• ODETICS Extension 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
CH4 - Channel 3, also referred to as COM4
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 5, 9, 13, 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. For example, one could attach an edit controller to Channel 1 for
record, playout, and editing; while an automation controller on Channel 3 manages play-to-air
operations. Alternatively, a single controller could control the operation of all server channels. A
single VDCP controller will commonly control multiple server channels.
It is also possible for a single VDCP controller to control multiple server channels.
