Section 8. Diagnostic
The CE2000-H8S/2238 emulator is designed to have all possible protective measures, but it is still
subjected to damage by user system or other unforeseen means. The CE2000-H8S/2238 emulator has a
built-in test modes: Standalone Test, in which all the internal functions and pins are tested thoroughly.
8.1 Standalone Self Test
The test is implemented to allow user to have a quick check of the hardware, before linking it to the PC.
This will help user to isolate the cause of the PC communication problem. The testing steps are:
•
Power on the CE2000-H8S/2238 emulator (the POWER LED lights up in RED).
•
Ensure the USB cable is not connected between the PC and CE2000-H8S/2238 emulator.
•
Wait for 10 seconds.
•
The emulator will enter Self Test mode (POWER LED changes from RED to ORANGE colour). After
the tests are completed (about 2 minutes), the POWER LED will start to blink, whereas the adjacent
RUN LED will light up in RED if the self test fails. However, if the self test passes, the RUN LED will
not light up.
NOTE: During the self test, the RUN LED will be turned on to GREEN occassionally. This merely
indicates that the emulator is in RUN mode.
