RFD2000 connection problem after restarting program.

When I try to connect to the collector (and the previous one has not been closed correctly), I am not able to do it in any way. I get the exception "com.zebra.rfid.api3.OperationFailureException" with the description: RFID_API_COMMAND_TIMEOUT

I am using TC20, RFD2000 and com.zebra.rfid.api3, RFID Manager

Is it possible to reconnect without restarting tc20 or reattach RFD2000

It seems to me that the problem is still the previous connection, but I do not know if I can force it to close
