Troubleshooting

Problem: Possible Solution:
Scanner is in sync with
the IBM, but there is no
communication with the
I/O racks
Check status of LED's at the ASB remote adapters: Red Light ON
indicates a Rack Fault Green Light ON indicates normal operation in
RUN mode. Green Light BLINKING indicates normal operation in
PROGRAM or TEST mode.
Check baud rate at the ASB and the setup_6008() routine.
Perform an AUTOCONFIGURE management request from either
your program, or the U_D1 diagnostic program. Determine whether
the adapter numbers returned by the cfg_info() routine corresponds
to those of the remote adapters. Use this formula to determine
adapter number:
Adapter # = 4 * rack + starting group / 2
Check remote I/O cable is made correctly and securely at both
sides:
C S B (clear, shield, blue) 15-pin D-shell 6 7 8
swing arm 3 2 1
Check power at the remote I/O rack.
Make sure that the host_active() routine is disabled during testing,
or is being called frequently enough to ensure the host watchdog
does not time out.
Problem: Possible Solution:
Scanner does not
communicate with the
IBM/ U_D1 diagnostic
program does not run.
Check specified interrupt vector. The vector must match the
hardware jumper setting discussed in chapter 3.
