Disconnecting Switches - AMX BCS Instruction Manual

Disconnecting Switches

The characters and numbers in a Disconnect command tell the system which input or output to
disconnect on which level. Command characters and numbers appear on the screen when the system
accepts them. A command string has successfully executed when the entered "T" command appears. If a
character or number is not accepted, a different character appears and all or part of the command is not
executed. For explanations of other possible responses, see page 5.
In disconnect commands, enter multiple levels and outputs or inputs by including a space between each
set of numbers. (You cannot enter multiple inputs and outputs in the same disconnect command.) Enter a
range of outputs or inputs by inserting a colon ":" between the lowest and highest numbers of the range.
If the level is not specified in the Disconnect command, the command is executed on the default level,
which is normally Level 0 (e.g., DO67T disconnects Output 67 on Level 0).
Important: If the level is not specified in a BCS command, the command is executed on the default
level (normally Level 0), which is defined in the configuration file. If the level is omitted and the
BCS command executes on an unexpected level, check the default level in the configuration file
(for systems without a configuration file, check the product documentation).
Caution: Disconnecting an input disconnects all the outputs receiving that source signal.
The following instructions provide command string formats for disconnecting switches by designating
either inputs (sources) or outputs (destinations).
To disconnect a switch:
1. Enter the Disconnect command below. Replace the "#"s with the level and output number(s) or
the level and input number(s).
DL#O#T or DL#I#T
