I also get this same error message. can you both try commenting out the call to request_identity2 and see if it works? I'd also need the command levels of both scanner. the identity2 is probably not strictly required. the only network scanner I have is the CX11 which has level B7 (IIRC) where the identity2 command is configured out. > > The reason for the failure in code seems reasonable.
