Dynamics AX 2012 R2 ---- Real Time Service (Thanks You)

I am trying to confgure AX 2012 R2, Real time service (not the web service) and followed the below steps:

                1. Firewall is completely off.

                2. RTS conguration:

                                Server:AX12-Test

                                Port:1239

                                Protocol:net.tcp

                                Passphrase: i have tried all possbile passphrases.

                                language: en-us

                                Realtime service  version:  AX 2012 R2

                3. Service is listening on the 1239 port number.

                4. As soon as i click inventory lookup atp pos error appears:  error number: 13010 could not connect to the transaction service,

                5. then i looked into the eventlog which showed the following error:

                LSRetailPosis.TransactionServices.InvokeMethod: System.ServiceModel.ProtocolException: You have tried to create a channel to a service that does not support .Net Framing.  ---> System.IO.InvalidDataException: Expected record type 'PreambleAck', found '46'.

6. Below is the transaction service configuration file setting:
