EX2000 Exciter Bulletin – Firmware Upgrade Required
An EX2000 Exciter firmware upgrade is currently required to prevent compatibility issues of certain tags not responding to Exciters.
All customers who have EX2000 Exciters are required to upgrade the Exciter firmware to DSP223. In addition, if you have Cisco Context Aware Engine for Tags (CLE), you are required to upgrade the CLE to version 18.104.22.168 or above.
Please refer to article #2178 on http://support.aeroscout.com for complete details. You can also reply to this email or call us at U.S. +1-877-AERO-555 (or +1-650-292-4953), EMEA & APAC +49-302-5555-094.
Determining the Exciter model can be done by one of the following methods:
a. The label on the back of the Exciter would say “EX2000” (not “EX2000B”)
b. Open AeroScout System Manager, right-click on the Exciter icon and select “Get Status” from the menu. For the EX2000, the HW version would be “2”.
