Hi,
I connected the CM-LTE-3 modem to the PC through RS485-USB converter. I set Gurux with the parameters:
-Iskraemeco
-HDLC
-Authentication none
-Client Address 46 (30+16)
-Logical Name Referecing on
-Physical Server 11
-Logical Server 1
-Serial COM4 9600 8N1
-DLMS standards
But the MT880 doesn't answer me. "Failed to receive reply from the device in given time".
