BCS Serial Control Protocol
AutoPatch has developed a command language, BCS (Basic Control Structure), for
operating the system through an external device and for diagnosing problems. The
Precis
LT
uses a subset of this language for switching, disconnecting, and verifying
status of commands. BCS command lines are entered into a terminal emulation
program (e.g., Windows HyperTerminal) from an external control device which
sends commands to the system. Control devices must be able to send and receive
ASCII code via an RS-232 port. For more information on external control devices,
see page 14.
Getting Started
General Rules for Using BCS Commands
ä
Command lines are not case sensitive.
ä
All command lines must end with the Take command “
T
” which tells the system
to execute the command.
ä
Command lines cannot be edited. If you make a mistake, enter an “
X
” and then
reenter the command.
ä
Entering “
X
” at any point in the command line cancels a command. A command
cannot be canceled after the “
T
” has been entered.
ä
If the level “
L
” designation is omitted, the command is performed on the default
level which is Level 0 for Precis
LT
models.
ä
To designate multiple inputs or outputs, enter a space between each number.
ä
Only disconnect commands accept multiple inputs; however, you cannot enter
multiple inputs and multiple outputs in the same command line.
ä
When verifying signal status, if a signal is only routed on one level, checking the
status on both levels will show the signal as not routed.
