=== Serial Operation === | |||
(Straight form the old website) | |||
The mux has a standard RS232 serial port on it, as well as various other (standard but unusual) communications ports. The serial port is what is used to control the mux automatically from the NetMuxController. | |||
Information returned via the serial link into hyperterminal when the unit is switched on: | |||
BASIC COMMAND LINE ENTRY SYNTAX | |||
BUFFER [#] [OFF/CLEAR] . . . Set or reset Buffer Mode, clear Salvo Buffer | |||
CLEAR # [,#,...] . . . . . . Cancel crosspoint or clear crosspoint request | |||
DESTINATION # [,#,...] . . . Take crosspoints or set crosspoint request | |||
EXECUTE # . . . . . . . . . Take Salvo Buffer crosspoint requests | |||
INFORMATION . . . . . . . . List system status and operational parameters | |||
LEVEL # . . . . . . . . . . Set current Level number | |||
POLL # . . . . . . . . . . . Poll source connections | |||
QUERY . . . . . . . . . . . List basic Command Line entry syntax | |||
READ . . . . . . . . . . . . List current crosspoint status | |||
SOURCE # . . . . . . . . . . Set current Source number | |||
TERMINAL [ON/OFF] . . . . . Set or clear Echo Mode | |||
VERIFY # . . . . . . . . . . List Salvo Buffer crosspoint requests | |||
XPT [#:] #,# [,#,...] [/...] Set specified crosspoints | |||
ZERO . . . . . . . . . . . . Reset X-plus frame | |||
The key commands are: | |||
* READ to find out the current inputs selected | |||
* LEVEL N to control which of the 4 outputs are selected for alteration | |||
* BUFFER A to assign a buffer to load commands into | |||
* BUFFER CLEAR to empty it | |||
* XPT X,01 to add a command to the buffer for input X | |||
* EXECUTE A to execute queued commands | |||
All commands can be abbreviated to the single initial letter. | |||
A simple example would be: | |||
>BUFFER 02 | |||
>BUFFER CLEAR | |||
>LEVEL 01 | |||
>XPT 03,01 | |||
>EXECUTE 02 | |||
Which sets output 2 (of 4) to input 3. When the EXECUTE command is sent. | |||
A more complex example, setting outputs 1 and 2 to 5, output 3 to 7 and output 4 to 10, would be: | |||
>BUFFER 01 | |||
>BUFFER CLEAR | |||
>LEVEL 00 | |||
>XPT 05,01 | |||
>LEVEL 01 | |||
>XPT 05,01 | |||
>LEVEL 02 | |||
>XPT 07,01 | |||
>LEVEL 03 | |||
>XPT 10,01 | |||
>EXECUTE 01 | |||
Reading back the status of the cards after this gives us: | |||
>READ | |||
Level 00: 01,05; | |||
Level 01: 01,05; | |||
Level 02: 01,07; | |||
Level 03: 01,10; | |||
with the inputs selected (5,5,7,10) clearly visible. | |||
