nn = 00-12 are transfer switch modules.
Position “00” is for the Polarization switch module.

v.vvv = version of firmware
4.2.24 PASS-THROUGH COMMAND
Although the NSU Control unit provides monitor and control capabilities for the
converters connected to the Redundancy Chain, there may be instances where
additional converter monitor and control may be required. The Pass-Through command
allows either SET or QUERY commands to be passed through the NSU Control unit
directly to the converter connected to a given position in the Redundancy Chain. For the
NSU control unit to communicate with a converter in the Redundancy Chain the NSU-
Converter Serial Link for that converter must be enabled.
Remote Command Sequence: *nnConverter_command
Response: *nnConverter_response
Where nn = “00” through “12” are the converter positions in the
Redundancy Chain represented by two digit ASCII numeric characters
The converter command and converter response are listed in the applicable manual for
the device being communicated with.
Example: Set the attenuation of 9700/9800/9900 style primary converter in redundancy
chain position one, to 4.2 dB. When sent directly to the converter the command to set
the attenuation is as follows:
Remote Command Sequence: $ATT042
Response: $ATT
When sent through the NSU Control unit to the converter in Redundancy Chain position
one would be as follows:
Remote Command Sequence: *01$ATT042
Response: *01$ATT
For 9400 and 9600 style converters the following example applies. When sent directly to
the converter the command to set the attenuation is as follows:
Remote Command Sequence: T042
Response: T
When sent through the NSU Control unit to the converter in Redundancy Chain position
one would be as follows:
