Query
5 bytes
Command or Query.
Sets or returns the threshold for the low forward power alarm/fault in the form xx.xx:
Default Value: 00.00 – Setting this parameter to 00.00 effectively disables the threshold.
NOTE: If the forward power drops below the specified value, the alarm/fault will be indicated.
COMMAND EXAMPLE: <0001/LPT=00.00{CR}
17 bytes
Query only.
Returns the read-only MAC address of the unit, reported in hexadecimal in the form xx-xx-xx-xx-xx-xx.
EXAMPLE: <0001/MAC?{CR}
>0001/MAC=00-06-B0-00-D2-A7{CR}{LF}
5 bytes
Command or Query.
Sets or returns the alarm mask conditions in the form abcde where:
0 = Fault, 1 = Alarm, 2 = Masked
a = Low Forward RF Power
b = External Reference Lock detect
c = Fan Speed
d = LNB Current Detect (NOT USED)
e = LNB 22V Power Supply (NOT USED)
NOTES:
1) Default Value = 2x1xx
2) If the value is set to 'Fault' (MSK=0) for a parameter, then the fault condition will be logged as a fault if
specified hardware conditions are not met.
3) If the mask value is set to 'Alarm' (MSK=1), then the fault condition will only log as an alarm.
4) If the mask value is set to 'Masked' (MSK=2), then the fault condition will not be reported to the user.
COMMAND EXAMPLE: <0001/MSK=2x1xx{CR}
1 byte
Command or Query.
Sets or returns the unit muting in the form x, where:
0 = Disable (Not Muted)
1 = Enable (Muted) (DEFAULT)
2 = Unit muted due to HW mute signal (SEE NOTE)
NOTE: This value is only shown in the response to a query, and cannot be issued as a command. When MUT=2
this means that one of the "hardware" mute conditions is present. Additionally, certain faults can generate a
hardware mute, e.g., BUC Lock Detect. If MUT=2, you must check the active faults and the status of the auxiliary
mute.
COMMAND EXAMPLE: <0001/MUT=1{CR}
3 bytes
Query only.
Unit returns the Number of Unread stored Events in the form xxx.
EXAMPLE: <0001/NUE?{CR}
>0001/NUE=126{CR}{LF}
