Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) If trouble does not clear, call Notifier Technical Support.
During the normal DIB polling/response cycle, which is explained above, this
trouble will be generated if the response received by the DIB is invalid or corrupt.
Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) If the trouble does not clear, call Notifier Technical Support.
Each time the system is powered up or reset, the DIB performs a test of both the
static RAM and nonvolatile RAM chips. This involves alternately writing zeros and
ones to each memory location on these chips and reading the information back. If
any of the chips fail the test, this trouble will be generated.
Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) If the trouble does not clear, call Notifier Technical Support.
Each time the system is powered up or reset, the DIB performs a test of the
operating system EPROM on the DIB board by looking at the checksum. This
trouble is generated if the EPROM fails the checksum.
Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) Replace the EPROM on the DIB with the one of the same software number or
one of a compatible set.
3) If the trouble persists, call Notifier Technical Support.
This message is generated if the Liquid Crystal Display on the Display Interface
Assembly "hangs up" and refuses to process any information. This is generally
caused by either a static discharge to the DIA or a failure on the DIA.
Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) If the trouble does not clear, call Notifier Technical Support.
DUART is an acronym for Dual Universal Asynchronous Receiver/Transmitter.
