1,2,3,4 - Serial Control Ports for channels 1,2,3 and 4
Each of the MAXX 2400’s four 9-pin “D” connectors permits independent control of any of the four
video channels. They can accept serial commands in VDCP, Sony BVW or Odetics protocol. The
multiple serial ports allow simultaneous connection of an automation controller and a desktop
controller. See the chapter on Automation Control for further details.
Most broadcast automation systems, and some remote control panels, employ the VDCP protocol.
A list of supported VDCP commands will be found in APPENDIX K - SERIAL COMMAND
PROTOCOLS. Many controllers used for transport, instant replay, and edit control employ Sony
BVW or Odetics protocol.
5,6 - GPI Control
The MAXX 2400 provides six GPI inputs for control of machine functions, which appear on the 25-
pin GPI connector. This “General Purpose Interface” can be connected to switch contacts or an
open-collector transistor output. GPI inputs are programmable, and can provide machine control
such as PLAY, STOP, or RECORD through simple external switches.
The MAXX 2400 also provides six GPI status outputs which may be used to confirm that a
command has been received, or for other purposes. The function of these open-collector outputs
are programmable, and may be used to operate an LED, or they can be connected to a suitable
logic input. The pin-out for the GPI connector will be found in APPENDIX I on Page130.
