Troubleshooting
The ADAM-5000 system provides two kinds of diagnosis:
hardware diagnosis and software diagnosis to help the user detect
and identify various types of system and I/O module failures.
7.1 Hardware Diagnosis
When the ADAM-5000 is first powered on, the system does a self-
diagnosis. The diagnosis information will be indicated on the LEDs
of the system module in the following sequence:
1. The LEDs will come on according to the following sequence: PWR
-> RUN -> TX -> RX,
2. Then all LEDs will go off
3. If the system self test is OK, the LEDs will follow the sequence
outlined in Steps 1 and 2. If the system has some problems,
the LEDs indicate errors as shown in the following table.
7.2 Software Diagnosis
The ADAM-5000 provides an ASCII command $AAE (Refer to the
command set in Chapter 6) to read the status of I/O modules through
the RS-232 port for field diagnosis or RS-485 port for remote diagnosis.
The response of such a command is !AAFFFFFFFF (FF represents the
error message of a slot from 0 to 3). The error messages are detailed
in the following table:
