2229 ! Mezzanine-module ID inva‐
lid
FID DPM Detector PIC: The mezzanine-
module ID value is not supported by this
DPM board. More specifically, the mod‐
ule value is pointing to a non-initialized
EEPROM region on the DPM. This may
indicate an invalid mezzanine module or
an older revision of the DPM that was
manufactured before the mezzanine
module was defined.
Verify the DPM revision level and re‐
place as needed.
Replace the mezzanine module on the
DPM.
2230 ! Mezzanine-module ID re‐
served
FID DPM Detector PIC: The mezzanine-
module ID value is set to a value re‐
served for future expansion.
Verify the DPM revision level and re‐
place as needed.
Replace the mezzanine module on the
DPM.
2257 ! Balance Failure FID on %4 FID DPM Detector PIC: A detector bal‐
ance sequence failed because of a hard‐
ware failure or because of an improper
configuration or sequence of events.
Some possible causes are:
The detector signal is not stable enough
and proper balance could not be ob‐
tained before the maximum number of
iterations was reached.
The A/D or D/A do not work properly.
The detector is not configured for acquis‐
ition or turned off.
SIMULATE_FID is set to 1 (the balance
cannot be done in detector simulation
mode).
The balance is disabled (DISABLE_BAL‐
ANCE_FID is set to 1).
The sampling period was changed dur‐
ing the balance sequence.
