21 bytes
Query only.
alphanumeric
Used to query the utility status of the MBT-400 Base Unit,
response is comma delimited, where:
aaaa=Physical Address
bbbb=Remote Baud Rate
Example: <0001/CUS?
6 bytes,
Command or Query.
numeric
A command in the form mmddyy, where;
dd = day of the month, between 01 and 31
mm = month of the year, between 01 and 12
yy = year, between 00 and 96 (2000 to 2096)
Example: DAT=042503 would be April 24, 2003.
n=1 AUX
Command or Query.
COMM1
EAM controls monitoring of external fault logic inputs to Aux
2=AUX
Comm connectors (J8/J9 pin F). If enabled and external fault
COMM2
input is at Logic 1 ( > 2.6 vdc) a fault will be reported.
m=0
Note: The inputs may be driven by a contact closure relay.

numeric
Valid Operating RF frequency, in MHz.
For Ku BDCs:
FRE values: 10950-11700 MHz an LO of 10000 MHz is activated
FRE values: 11701-12250 MHz an LO of 10700 MHz is activated
FRE values: 12251-12750 MHz an LO of 11300 MHz is activated
Example: FRE=11300.000
Query only
Gets the Firmware Number of the unit.
Example: FRW=FW12001'cr''lf'
