Summary Status
Command Byte : '1'
Response : "AB" formatted as follows:
Byte 'A'
Bit 7: Reserved
Bit 6: Complement of Bit 5
Bit 5: Power Supply Enabled
Bit 4: High Voltage On
Bit 3: Standby
Bit 2: Remote Mode
Bit 1: Constant Power On
Bit 0: RF Inhibited
Byte ‘B’
Bit 7: Reserved
Bit 6: Complement of Bit 5
Bit 5: Summary Fault
Bit 4: Heater Standby
Bit 3: Output Power changed 0.2 dB since last
Power Out query
Bit 2: Alarm Exists
Bit 1: High Voltage Level Reduced (If using a
XTC-100D which is configured for analog
ODUs , this bit means: AMP Not Connected)
Bit 0: Auto HV ON (HV selected, but HV not
ON)
Notes :
Power Supply Enabled is only defined for amplifiers connected to a controller. If you query an
amplifier through a controller, the controller generates the summary status response on behalf
of the amplifier. Thus it can indicate Power Supply Enabled status. Amplifiers cannot respond
to queries if power is off.
If High Voltage On and Standby are both zero, the amplifier is in "Filament Time Delay."
Outdoor Units are always in Remote Mode unless they are configured with a Local Override
switch.
RF can be inhibited through the user front panel or by serial command.
The High Voltage Level is Reduced/Restored via command 'N’. This bit is defined for Tri-Band
amplifiers with the Voltage Shift Option.
