Executing Switches
A switch is an active connection between an input (source) signal and one or more output (destination)
devices. The signals connected in a switch command are either individual signals or groups of signals
coming through the connectors on the rear of the enclosure. When executing a switch, you must specify
a level that contains all the signals you want to route (or the switch will execute on the default level,
normally 0). Levels are determined in the configuration definition that has been loaded onto each CPU in
the system.
A switch command string begins with the character “
C
” which initiates a Change command for routing a
switch. The characters and numbers that follow the “
C
” command tell the system which inputs and
outputs to connect on which level. The last character is the Take “
T
” command which tells the system to
execute the command.
For example, the command string
CL0I102O39T
can be interpreted as follows:
[
C
] Change on [
L0
] Level 0, [
I102
] Input 102 to [
O39
]Output 39, [
T
] Take to execute the command.
For a complete list of command characters and their functions, see page 4.
Command characters and numbers are echoed back to the terminal screen as the system accepts them.
A command has successfully executed when the entered “
T
” command appears. If a command 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 each Change command, you can enter multiple levels and multiple outputs (destinations), but only
one input (source). To enter multiple levels and outputs, include a space between each set of numbers.
To enter a range of outputs, insert a colon “
:
” between the lowest and highest numbers of the range.
If the level is not specified in the Change command, the command is executed on the default level, which
is normally Level 0 (e.g.,
CI72O35T
routes Input 72 to Output 35 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).
The following instructions provide command string formats for executing switches by designating either
an input or one or more outputs first.
To execute a switch:
1.
Enter the Change command below. Replace the “
#
”s with the level, input, and output number(s).
CL#I#O#T
or
CL#O#I#T
