Metcom- Connect meters in daisy chain over RS485

Hi,
Thanks for all your support till now!
Now, I am prototyping the Metcom meter connectivity. We have Building Management System which exposes an IP and port which is connected to the series of Metcom meters in daisy chain using RS485.
I am using GURUX java client example (somewhat modified for us) to connect to this Metcom meter. Adding the sample code.

****************************************
GXDLMSSecureClient2 dlmsClient = null;
GXDLMSReader reader = null;

String meterType = "Metcom";
String ipAddress = "100.100.100.100"; // -h dummy IP
String portNumber = "61001"; // -p
String clientAddress = "1"; // -c
String serverAddress = "10181272"; // -s
String authenticationLevel = "LOW"; // -a
String password = "XXXXXXXX"; // -P
// Boolean shortName = true; // -r
Boolean useLogicalName = true; // -r - Metcom uses Logical name but LG uses short name
InterfaceType communicationInterfaceType = InterfaceType.WRAPPER; // -i Metcom uses WRAPPER but LG uses HDLC

// Create connection
GXNet connectionMedia = new GXNet();
connectionMedia.setHostName(ipAddress);
connectionMedia.setPort(Integer.parseInt(portNumber));

// Create Client
dlmsClient = new GXDLMSSecureClient2(true);
dlmsClient.setUseLogicalNameReferencing(useLogicalName);
dlmsClient.setInterfaceType(communicationInterfaceType);
dlmsClient.setAuthentication(Authentication.valueOfString(authenticationLevel));
dlmsClient.setClientAddress(Integer.parseInt(clientAddress));
dlmsClient.setServerAddress(Integer.parseInt(serverAddress));
if ( dlmsClient.getServerAddress() != 1 ) {
dlmsClient.setServerAddress(GXDLMSClient.getServerAddress(Integer.parseInt(serverAddress))); // setting 2272
}
dlmsClient.setPassword(password);

// Initialize reader
reader = new GXDLMSReader(dlmsClient, connectionMedia, TraceLevel.INFO, null);
// Open connection
connectionMedia.open();
reader.initializeConnection();
// Read association view
reader.getAssociationView();

I couldn't connect to the meter and getting Invalid connection error Adding the trace file.

Exception in thread "main" java.lang.RuntimeException: Invalid connection.

Could you please help me out to put the proper configuration and connect the meter.
