HAN Interface of meter

Hello,

I am working with a smart energy meter using Gurux.

I successfully connected to the meter using the optical interface (IEC 62056-21) and was able to:

Read meter data Zpa am165

Read the meter name/identification

I then tried to connect using the Ethernet (HAN) port with:

Laptop → USB-to-Ethernet adapter

Direct Ethernet cable to the meter

No router in between

The Ethernet link does not come up (Windows shows network cable unplugged,)

Hi, IEC 62056-21 is not DLMS…

Hi,

IEC 62056-21 is not DLMS. https://gurux.fi/DLMSCOSEMFAQ

Check first is the HAN Ethernet port. It's usually the serial port.

BR,
Mikko
