Why doesn't my CEI-520A function properly when using BusTools/ARINC?

First, make sure that version 3.80 or later of the CEI-x20-SW distribution is installed (see M-INFO-90220 below for details).

Next, make sure you're using the latest version of BusTools/ARINC:

 If you're currently using BusTools/ARINC v2.61 or earlier:
Upgrade to the latest version of BusTools/ARINC to support the CEI-520A. A downloadable upgrade from v2.61 is available on the BusTools/ARINC download page. If you are upgrading from a version of BusTools/ARINC prior to v2.61, contact Condor Sales (avionics-sales@gefanuc.com) for upgrade assistance.

If you're using the latest version of BusTools/ARINC:
Contact GE Fanuc Intelligent Platforms technical support (avionics-support@gefanuc.com) for assistance.
