Response to
Query
AUPC
Parameters
APP=
6 bytes
Command or Query.
Defines AUPC operating parameters in the form abc.cd:
a=Defines action on max. power condition, where:
(0=do nothing, 1=generate Tx alarm)
b=Defines action on remote demod unlock, where:
(0=go to nominal power, 1=go to max power)
c.c=Target Eb/No value, for remote demod from 0.0 to 14.9 dB, where:
numbers above 9.9 use hex representation for the first character, i.e. 14.9 is coded as E.9.
d =Max increase in Tx Power permitted, from 0.0 to 9.0 dB
Example: APP=015.67 (Sets no alarm, max power, 5.6 dB Target and 7 dB power increase.)
In IP-ACM mode:
a=Defines action on max. power condition, where:
(0=do nothing, 1=generate Tx alarm when max power is reached, 2=generate Tx alarm when mimimum
ModCod is reached)
b=Defines action on remote demod unlock, where:
(0=go to nominal power, 1=go to max power, 2=hold)
c.c = Max increase in Tx Power permitted, from 0.0 to 9.9 dB OR when CnC mode is on, from 0.0 to 3.0 dB
d = Mode (0=Normal, 1=+/- Track), read-only

Remote
Eb/No
N/A
4 bytes
Query only.
Returns the value of Eb/No of the remote demod in the form xx.x, where:
xx.x=02.0 to 16.0
Responds 99.9 = remote demod unlocked.
Responds xx.x if EDMAC is disabled.
Example: REB=12.4
Note: For values > 16.0 dB, the reply will be 16.0
N/A
REB?
REB=xx.x
(see Description of
Arguments)
Tx Power
Level
Increase
N/A
3 bytes
Query only.
Returns the increase in Tx power level, in dB (from the nominal setting) due to the action of AUPC.
Responds x.x if AUPC is disabled.
Example: PLI=2.3
N/A
PLI?
PLI=x.x
(see Description of
Arguments)
Tx Clock

TCK=
1 byte, value
of 0 thru 3
Command or Query.
Tx Clock Source, where:
0=Internal
1=Tx Terrestrial
2=Rx Loop-Timed
3=Ext TT (ST=RxSat)
Example: TCK=0 (selects Internal)
