Description of Arguments
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
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
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
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)
