Controller)
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)
DAT* (message OK,
but not permitted in
current mode) DAT?
DAT=mmddyy
(same format as
command
arguments)

enabled)
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 EAM=(message OK)
EAM?(received OK,
but invalid arguments
found) EAM?n EAM=nm
(same format as
command
arguments)
Operating
RF Frequency FRE=xxxxx.xxx BDC
BUC
9 bytes,
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)
FRE? (received OK,
but invalid arguments
found)
FRE* (message OK,
but not permitted in
current mode)
FRE! (command not
accepted by MBT-
4000 base unit. It
must be addressed
to BUC or BDC sub-
units) FRE? FRE=xxxxx.xxx
(see description
of arguments)
