Troubleshooting GPIB Communications Problems

1. Check the PDLA Status Log
2. Ensure that GPIB cables are configured correctly.
3. Check the system GPIB Addresses.

If the PDLA application is running, check the PDLA Status Log
for any warnings or errors. Press
status messages.
Highlighting a message in the log may cause additional details to
be shown.
Check the GPIB cables; they should match
If the MWM is used, it must also be attached with another GPIB
cable.
The system is configured to work with predetermined GPIB
addresses for the tunable laser source and multi-wavelength
meter (when applicable). If the GPIB addresses for these
instruments have been changed, the PDLA application will not
be able to communicate with them.
The factory default address for an 8164B and an 86122A is the
same — 20. If both instruments are on the bus with the same
GPIB address, you may get confusing error messages, likely a
message that says the PDLA Application cannot contact the
tunable laser source.
Follow the details below to check and reset the GPIB addresses
on the tunable laser source and multi-wavelength meter. The
GPIB address cannot be changed from the PDLA software, but
must be altered on the individual instruments.
