TSS MINI Operations Manual
Most broadcast automation systems and some remote control panels employ VDCP
protocol. Many controllers used for transport, instant replay, and edit control employ BVW
or Odetics protocol.
Note that the server does not respond or provide status for all messages that are specific to
tape machines. As such it may not operate with editing systems designed for use with tape
machines.
Figure 2 – CXP-5 Module Connectors
GPIO Control
The CXP-5 module provides twelve GPIO inputs for control of machine functions, which
appear on two 25-pin
GPIO
connectors. These “General Purpose Inputs” can be connected
to switch contacts or to 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 CXP-5 also provides twelve GPIO Outputs which may be used to confirm that a
command has been received, to trigger operations on external equipment, or provide
warning indications for system errors. The function of these open-collector outputs is
programmable; they may be used to operate an LED, or they can drive a suitable logic input.
The pin-out for the GPIO connectors will be found in APPENDIX A.
