(Instruction
& Qualifier)
Response to Query
AUPC
Parameters
APP= 6 bytes
Command or Query.
Defines AUPC operating parameters. Has the form abc.cd, where:
a=Defines action on max. power condition.
(0=do nothing, 1=generate Tx alarm)
b=Defines action on remote demod unlock.
(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 1 st
character, ie 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.
APP=

APP# APP? APP=abc.cd
(see description of
arguments)
Remote
Eb/No N/A 4 bytes
Query only.
Returns the value of Eb/No of the remote demod.
Responds 99.9 = remote demod unlocked.
Responds xx.x if EDMAC is disabled.
xx.x=02.0 to 16.0
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
Source 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)
TCK=
TCK?
