Severity Description Explanation
08060-0 ADM WARNING Antenna modem ACU/Antenna communication error detected
(framing and parity). If the situation is persistent,
check if cable specifications comply (length and
attenuation).
08063-0 ADM ERROR Antenna connection The ACU has lost connection with the antenna.
08064-0 ADM ERROR ADM PLL lock The intermediate frequency PLL is not in lock.
Check the 10 MHz reference signal.
08065-0 ADM WARNING GNSS data Missing GPS data (fix).
08066-0 ADM WARNING Heading data Missing heading information. Check cable and
heading provider device.
08067-0 ADM ERROR PCB temperature ADM temperature too high. The ACU is not
equipped with a fan, so make sure there is
compliance with the environmental specifications.
08068-0 ADM ERROR PSM power The PSM fails to provide the requested supply
voltage.
08069-0 ADM WARNING Blocking Zone The antenna has entered a blocking zone.
0806A-0 ADM WARNING VMU connection The ACU has lost connection with the sat modem.
0806C-0 ADM ERROR VMU frequency setup There is a mismatch in the frequency setup.
Probably the sat modem is not configured
correctly to match the requirements of the ACU
and antenna. A common mismatch is the absence
of Rx or Tx LO parameter in the VSAT modem.
0806D-0 ADM ERROR Antenna power The antenna supply voltage is outside the allowed
limits. This could happen if the PSM fails to
provide the requested supply voltage or if the
voltage difference across the hotswap is
unacceptable high.
0806E-0 ADM ERROR VMU 10 MHz reference The VMU Rx or Tx reference signal is not present.
Whether this error Rx or Tx reference, depends on
the users selection on the modem profile page.
Make sure VMU Rx/Tx cable is connected and that
the VMU is configured to output the RX/TX
reference signal.
