Developer Portal | Bug in .NET SDK with "Tag event" option?

Hello!

We use FX7500 along with C# .NET SDK but even when we use your compiled genuine .exe from SDK suite and when checking this option "Tag event" after some minute of scanning, Actv and Pwr bulbs go DIMMED-green and connection with RFID reader is lost (see screenshot).

Sometimes we get some "Reader ExceptionEvent Reset NGE due to error type (2)" message also with disconnection event immediately afterwards!

It looks like when it comes to some 1000-2000 "tag-seen events", your exe just breaks down?

Is there some workaround on this , is this bug or?

Regards...

ADDITION: I tried with PowerSession app as well and same thing happens after some minute of reading: see the 2nd screenshot..

This issue also happens with

This issue also happens with inadequate power from a PoE port as well.

Scenario:

FX7500 on PoE port with 12000 mW limitation. When an RFID tag inventory was started the FX7500 stopped communicating completely (via ICMP PING / ARP, etc).

FX7500 on P4 (restricted to 12000 mW)

Sitting idle is OK because it draws only 7200 mW
Running RFID inventory is NOT OK because it runs at 17000mW or higher

FX7500 on P3 (restrictedto 22000 mW)

Sitting idle is OK
Running RFID inventory is OK (doesn't surpass the 22000 mW restriction)

FX7500 running RFID tag inventory (with one antenna) - this was within the Port 3 power restriction, but surpassed the Port 4 power restriction
