Hi,
I am using gurux_dlms for python and I would like to know how to configure the translator properly
Here is my code

from gurux_dlms import *
from gurux_dlms.enums import TranslatorOutputType
from gurux_dlms.enums import Security
encrypted_data = "7EA03800021611F1544CC6E6E600DB0857534530303030311E30000000A96437FABDDBB43C3FE046C960BC9061849413AA1B68D45876B981E27E"
t = GXDLMSTranslator(TranslatorOutputType.SIMPLE_XML)
t.comments = True
t.security = Security.AUTHENTICATION_ENCRYPTION
t.systemTitle = bytes.fromhex("5753453030303031")
t.authenticationKey = bytes.fromhex("D0D1D2D3D4D5D6D7D8D9DADBDCDDDEDF")
t.blockCipherKey = bytes.fromhex("000102030405060708090A0B0C0D0E0F")
xml = t.messageToXml(encrypted_data)
print(xml)

and here is what I got
<HDLC len="37" >
<!--Logical address:1, Physical address:1416-->
<TargetAddress Value="4588" />
<SourceAddress Value="78" />
<!--I frame.-->
<FrameType Value="54" />
<PDU>
<GeneralGloCiphering>
<SystemTitle Value="5753453030303031" />
<CipheredService Value="30000000A96437FABDDBB43C3FE046C960BC9061849413AA1B68D45876B9" />
</GeneralGloCiphering>
</PDU>
</HDLC>

but the translator in GXDLMSDirector is capable to translate
Here is what I got
