The current issue:
The background is that the c8100 is sending upon startup the masking status, due to the complexity of the masking available on the c8100 various maskings are being sent.
BRF1 Instrument Masking 00 = Masking inactive
BRF1 Module Offline 00
If the Instrument masking at the 8100 is set upon Startup on the c8100, cITm receives the
BRF1 Instrument Masking 01 = Masking active
However the next message is being sent to MW and this is the
BRF1 Module Offline 00
This additional message within the current driver causes the masking to be set to 00, the reason is that all masking messages from the c8100 are considered to be the same.
8100 Driver version:3.8.1.42
cITm serial number: 200152
