Command or (note that all arguments are ASCII numeric codes, that is,
Response to ASCII codes between 48 and 57)
Query
6 bytes, Command or Query.
Defines AUPC (Automatic Uplink Power Control) operating
parameters. Has the form abc.cd Where:
a = Define action on max power condition:
0 = do nothing
b = Define action on remote demod unlock:
0 = go to nominal power 1 = go to max power
c.c = Target Eb/No value, in dB, for remote demod
d = Maximum increase in Tx Power permitted, in dB
Example: APP= 015.67
4 bytes, Query only. (AUPC feature)
numerical Returns the value of Ebi/No of the remote demod, if Framing
is enabled.
Returns 99.9 if demod is unlocked.
Returns xx.x if Framing is not enabled.
Range: between 2 and 16dB. Resolution 0.2 dB.
Example: REB=12.4 (which is Eb/No = 12.4 dB)
For values > 16.0 dB, the reply will be REB=16.0
3 bytes, Query only. (AUPC feature)
numerical Returns the increase in Tx power level, in dB (from the
nominal setting) due to the action of AUPC.
Returns x.x if AUPC is not enabled.
Example: PLI=2.3
1 = generate TX alarm
