Introduction
This section details the addition of the Parameter-Based Command Set
(PBCS), to the original switcher protocol. The PBCS consists of three
commands (read, set and trim), which allows a remote controlling device
the ability to query the current state of selected parameters, and to change
those states as required.
Examples include:
■
Ask the switcher what the current crosspoint selection is on the Key 1
bus for M/E 2.
■
Query the E-MEM system for current register and enables status.
■
Query the Keyers for the current On Air and Next Transitions mode
status.
■
Query the conÞguration database for information about current system
setup parameters.
The initial implementation of PBCS occurs with the release of switcher
software version 5.3 and contains a subset of the entire command set. Each
description of a particular command that follows includes the software
version in which that feature will be released.
NOTE:
Note that with software version 5.3, set and trim commands are not
implemented at this time.
