In the latest firmware for the FX7500 reader, 1.3.13, there was a new API provided, containing the RFIDAPI32PC.dll version 22.214.171.124
The firmware upgrade for the FX7500 reader works smooth however, when i try to use the same dll for a firmware upgrade at a FX7400 model, i get this error:
Error Code: 65535, Error Description: RM Server not running
Then the reader gets a red light blinking which does not stop until i manually reset the reader.
Should this newer dll support also the FX7400 reader?
