Python DLMS example - Commands failing

Hi there,

I am trying to read the Landys-Gyr E650, via a Kocos optical eye. I have had success connecting with the GXDLMSDirector but I cannot connect using the python example. I am VERY new to this sort of thing so please bear with me.

I try to copy/ paste the command line given by the Director but the results are the following:

py Gurux.DLMS.Client.Example.python\main.py -S COM3:9600:8NoneOne -r sn -iHdlcWithModeE -n 95669535 -t Verbose

gurux_dlms version: 1.0.104
gurux_net version: 1.0.17
gurux_serial version: 1.0.15
Traceback (most recent call last):
File "C:\wamp64\www\Gurux.DLMS.Python-master\Gurux.DLMS.Client.Example.python\main.py", line 79, in main
ret = settings.getParameters(args)
File "C:\wamp64\www\Gurux.DLMS.Python-master\Gurux.DLMS.Client.Example.python\GXSettings.py", line 209, in getParameters
self.media.parity = Parity[tmp[2][1: len(tmp[2]) - 1].upper()]
File "C:\Python39\lib\enum.py", line 432, in __getitem__
return cls._member_map_[name]
KeyError: 'NONEON'
Ended. Press any key to continue.

I have tried a few other variations of commands with different results. But I still cannot connect to the meter.

Thanks :)
Dylan
