The
half-Y
serial protocol is as follows:
q
9600 baud
q
8 data bits
q
1 stop bit
q
No parity
All BCS entries must be complete commands. Terminate any
incomplete or erroneous commands with an ‘X’ (Cancel) and
then re-type the command. Typing a space or a backspace
does not cancel a previous command.
The following table shows the BCS commands available for
your
half-Y
.
To make a switch using BCS commands:
Enter the correct string of BCS commands for the switch you
want to make. Every switch command must begin with ‘C’
and end with ‘T’. 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.
One advantage of using BCS commands is that you can enter
multiple commands in the same string. For example, you can
switch level 1, input 1 to level 1, outputs 1 and 2 with one
command string. That command string would look like this:
CL1I1O1 2T
C-4
