Communications Problems
If the ODA application is running, check the ODA Status Log for any
warnings or errors. Press
Check the GPIB cables, they should match
The system is configured to work with set GPIB addresses for the tunable
laser source and multi-wavelength meter (when applicable). If the GPIB
addresses for these instruments have been changed, the ODA application
will not be able to communicate with them.
The 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 ODA 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 ODA software, but must be altered on the
individual instruments.
