EXECUTING AND DISCONNECTING
SWITCHES USING BCS COMMANDS
You can use BCS with a device that connects to
the serial connector on the Precis CPU. BCS
commands are a subset of the X
N
Net
communications protocol.
EXECUTING SWITCHES
To execute a switch, enter the command using
the following command line format (where “#”
represents any valid level, source, or destination
number).
CL#I#O#T or CL#O#I#T
To cancel an incomplete BCS command, enter
the “X” command at any time.
Examples:
BCS
Command
Action
CL0I6O2T
Switches source 6 to destination 2
on Level 0 (default is audio and
video)
CL1I6O2 4T
Switches source 6 to destinations
2 and 4 on Level 1 (default is
video only)
CL2O2I5T
Switches source 5 to destination 2
on Level 2 (default is audio only)
CL2I6X
Cancels the incomplete command
Note: You can enter multiple destinations in
each execute switch command by including a
space between each destination number, but you
can enter only one source signal and only one
level.
DISCONNECTING SWITCHES
To disconnect a switch, enter the command
using the following command line format (where
“#” represents any valid level, source, or
destination number).
To disconnect a source from all destinations,
use the second format.
DL#O#T or DL#I#T
To cancel an incomplete BCS command, enter
the “X” command at any time.
Examples:
BCS
Command
Action
DL1O6T
Disconnects destination 6 on
Level 1 (default is video only)
DL1I2 4T
Disconnects sources 2 and 4 from
all destinations that are receiving
that signal on Level 1 (default is
video only)
DL2I6X
Cancels the incomplete command
Note: You can enter multiple sources and
destinations in each disconnect switch command
by including a space between each number, but
you can enter only one level.
See “BCS (Basic Control Structure) Commands”
on page 25 for a complete list of the BCS
command characters.
