3. Check that the DIP switches on the AS-HV side panel are set correctly
(see Section 2.2 ).
4. Check that the AS-HV and the Chromeleon PC have the same serial port
parameters. Refer to Section B.3.14 for the correct settings.
5. Initialize the AS-HV to verify that it is in a working state. (Turn off the
power, wait 10 seconds, and turn on the power again.)
6. Send some commands from Chromeleon to the AS-HV; while the
commands are being sent, observe the HOST LED on the AS-HV:
If the
HOST
LED flashes while commands are being sent, it confirms
that the AS-HV has received a character from the PC. The AS-HV
always responds when a carriage return (the
Enter
key) is received,
regardless of the success of the message. This confirms that the baud
rate is correct.
If the HOST LED does not flash while commands are being sent,
confirm that the AS-HV is functioning by watching for the
CPU
LED
to flash. If the CPU LED does not start flashing within 10 to
15 seconds, press the
Reset
button to implement the reset sequence
and then wait until the CPU LED flashes. If this is successful, try
again to send commands from Chromeleon to the AS-HV. If the
HOST LED still fails to flash, contact Dionex for assistance.
Cause:
The AS-HV firmware detected an invalid setting for a configuration variable
in Chromeleon.
To troubleshoot:
1. Check that the AS-HV and the Chromeleon PC have the same serial port
parameters. Refer to Section B.3.14 for the correct settings.
2. Check that the cable between the AS-HV and the PC is firmly connected
and screwed into place.
3. Initialize the AS-HV to verify that it is in a working state. (Turn off the
power, wait 10 seconds, and turn on the power again.)
Invalid configuration variable.
