Concise Utility
Status
N/A MBT 21 bytes
alphanumeric
Query only.
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?
>0001/CUS=aaaa,bbbb{cr}{lf}
N/A CUS? CUS=x…x
(see description
for details of
arguments)
Set RTC
(Real-Time-
Clock) Date
DAT=mmddyy All 6 bytes,
numeric
Command or Query.
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.
DAT= (message OK)
DAT? (received OK,
but invalid arguments
found)

Command or Query.
EAM controls monitoring of external fault logic inputs to Aux
Comm connectors (J8/J9 pin F). If enabled and external fault
input is at Logic 1 ( > 2.6 vdc) a fault will be reported.
Note: The inputs may be driven by a contact closure relay.
They have an internal pull-up resistor (4.7k) to +5 vdc.
Example: EAM=21

numeric
Command or Query
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
FRE=(message OK)
