Query:
PEI?
Returns: PEI192.168.1.10 where 192.168.1.10 is the IP Address of the
Amplifier.
Query:
PHX<?>
H = Heater
X = parameter you wish to query -- V for heater voltage, I for heater current.
Query:
PHV?
Returns: PHVnn.n where nn.n is the measured heater voltage in volts.
Query:
PHI?
Returns PHInn.n where nn.n is the measured heater current in milliamps.
Query:
PKn<?>
K = Firmware checksum.
1 = Test Firmware checksum.
2 = Calculate and return Firmware checksum.
Examples:
Query:
PK1?
Returns: PKs where s is a string: “OK” or “FAIL” (note white space around
strings.)
Query:
PK2?
Returns: PKXXX, where XXX = 8 bit checksum value (0-255)
Query:
PX?
X = Transmit Power-up state
Returns: PXn where n is the power ON state: 0 = NORMAL (the last state
before Power OFF); 1 = OFF (Power-up into Standby mode); 2 = ON (Power
-up into Transmit mode).
Reference Frequency Fine Tuning Word
Command String: “
PBM?”
Function:
Query for reference frequency tuning word.
Response: “
PBMxxxx”
Where: xxxx = 0-4095
Compatability:
Not supported by all amps. If feature is not supported, the
command will be NAK’d.
Status LED Mode
Command String: “
PBW?”
Function:
Queries amplifier for the operating mode of the status LED.
Response: “
PBWx”
‘x’ is a ‘0’ or ‘1’, indicating the operating mode of the status LED. ‘0’ = normal
mode; ‘1’ = disabled mode (LED off).
Compatability:
Only applies to Outdoor amplifiers. Not supported by all
ODU amps. If feature is not supported, the command will be NAK’d.
