List of 07-09-2020
Error code Unit 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 external reference signal.
08065-0 ADM WARNING GNSS data Missing GNSS 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. 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 to the satellite modem.
0806C-0 ADM ERROR VMU frequency setup There is a mismatch in the frequency setup. Probably
the satellite 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 satellite modem.
0806D-0 ADM ERROR Antenna power The antenna supply voltage is outside the allowed
limits. This may happen if the PSM fails to provide the
requested supply voltage.
0806E-0 ADM ERROR VMU reference signal There is no VMU Rx or Tx reference signal. Whether
this is Rx or Tx reference depends on the user's
selection on the modem profile page in the web
interface. Make sure the VMU Rx/Tx cable is
connected and that the VMU is configured to output
the RX/TX reference signal.
0806F-0 ADM WARNING ROSS synchronization The ACU has become out of sync with the ROSS
device, most likely because the ACU has been
replaced, or the ROSS satellite profile is new. A manual
(forced) handoff sequence must be initiated from the
ROSS, refer to the ROSS manual.
08073-0 ADM WARNING Slave connection The system is configured as a dual antenna master,
but no dual antenna slave is connected to it. Either
disable the dual antenna master in the web interface
or configure a another system as a dual antenna slave.
