How do I configure the RS485 ports on the A1500 Elster meter and Moxa converter?

Welcome
Here is the issue to be solved.
An A1500 Elster energy meter with two RS485 ports (the first one occupied by a modem), a Moxa nPort 5130 RS485/Lan converter, AlphSET software.
I connected such a meter to the RS485 converter. In the AlphaSET counter software, I set up communication with the counter via TCP/IP. There I inserted the IP parameters of the converter. This works.
AlphaSET sees and connects to the converter, but the converter does not communicate with the counter.
What potru parameters do I have to zapoid to be communication counter <=> converter<=> AlphaSET?

You should have these parameters with your device because it was the manufacturer who set the speed and other communication values with the software.

An old topic admittedly, but I have recently seen such communication set to 300.7.e.1 - I would check this first.

And does anyone know where to get this AlphaSet program from?
