Description of Arguments
to Query
Query only.
Unit returns the redundancy state of the unit, where
0=Offline
1=Online
Example: RED=1 (which is Online)
Query only.
Unit returns the value of the internal software revision installed in
the unit, in the form of x.x.x
Example: SWR=1.0.3
Query only.
Unit returns hardware revision level of both main circuit cards,
where xx indicates the main (bottom) card, and y indicates the top
(modem) card.
Query only.
Used to query the unit 9-digit serial number. Unit returns its S/N
in the form xxxxxxxxx.
Example: SNO=176500143
Query only.
Unit returns the checksum values for the Boot, Main, and FPGA
sections of firmware, in the form:
Boot:XXXX Main:YYYY FPGA:ZZZZ, where:
XXXX=the integer sum checksum for the Boot Block.
YYYY=the integer sum checksum for the Main Block.
ZZZZ=the integer sum checksum for the FPGA Block.
Example: FCS=Boot:5AB2 Main:81FE FPGA:C5AO
(Takes a few seconds to respond.)
