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:
