Wolfpack Component Video Matrix Switch
[?S,C]
The fault message contains a fault code number as shown below. This number
must be processed by the control system software to determine what faults are
present. Here is an example:
[S,C,12345]
Once the actual fault has been resolved, the system will then transmit the
following:
[S,C,0]
To convert the code into useful information, do the following:
1) Convert the ASCII string of numbers to a 16 bit integer value.
2) Lookup each bit position in the following table to determine what fault
or faults are present:

Tip - A simple way to program for faults is to
query "[?S,C]" and look for the response string
"[S,C,0]". If the code is not zero, there is a fault
present.
The verbosity setting [S,V,x] also has an affect on fault messaging through the
serial ports. In the default state of verbosity ON (1), the system will transmit
faults as they occur and clear themselves. With verbosity turned OFF (0), the
system will only send a fault message as a response to a fault query [?S,C].
When using the USB port, the matrix switch will be installed as a virtual COM
port. This means that any control program capable of controlling a device
