To disconnect a switch using BCS commands:
Every disconnect command string must begin with ‘D’ and
end with ‘T’. In a disconnect command string, specify the
level and input or output you want disconnected. If no level is
specified, the input or output is disonnected on all levels.
Enter the correct string of BCS commands for the input or
output you want to disconnect. To delete errors in your
string, enter an ‘X’ and re-enter your entire command string.
The ‘X’ cancels every portion of the command string that came
before it. You can disconnect level 1, outputs 1 and 2 with the
following command string:
DL1O1 2T
C.2.2 BCS Software Handshaking
All AutoPatch software provides software handshaking.
However, other software may not. If you are using something
other than AutoPatch software, make sure it implements the
following handshaking requirements.
Each character received by the distribution matrix CPU is
echoed through the DB-9 port. When a switch is completed in
the matrix, the BCS command ‘T’ is echoed. Your external
serial control software must wait until it receives the echoed
‘T’ back from the CPU before it sends the next command.
Waiting for the ‘T’ command prevents serial buffer overflow
when software handshaking is unavailable.
C.3 Software
Control software allows your to use a PC to control your
matrix through the DB-9 ports. AutoPatch offers control
software that executes switches manually and automatically.
Manual execution software implements commands as they
are entered. Automatic execution software implements
commands at the times they are scheduled to be executed.
The manual execution software package is YRoute. The
automatic execution software packages are AutoRoute Event
Scheduler and ScanPatch.
C.3.1
YRoute
YRoute is a DOS-based software package that simulates all
configuration operations, except checking the status of an
input or output. Implement operations by entering the
commands (at the top of the screen) at the option? prompt.
Before using YRoute, familiarize yourself with the operation
of your distribution matrix from the X/Y Control Panel.
YRoute can only be run on a PC that uses RS-232
communications.
Note:
Using YRoute requires an RS-232 cable with the
hand shaking pins shorted. See figures C.1 - C.4 in
the “Connecting Serial Controllers” section of this
appendix.
