I have strange problem with connection to EMH LZQJ-XC. Here is log:

Other infos:
- Checked protocols IEC and DLMS with, and without Logical name referencing
- Using serial port through ethernet didn't change anything
- I don't use Variomod-XC
- Meter was produced in 2018
- We try to connect through rs232 and moxa nPort 5150
What should I do to fix the problem? What else you want to know?
It seems that meter is returning something, but it's not correct data. Check your serial port settings that they are same on the meter what they are in Moxa.
Try connect without Moxa. Then check Moxa settings.
Without moxa, the meter still returns bad response.

Settings on moxa are good. I don't know why this isn't working.
Is this possible, that the variomod is necessary? Do you have any ideas? Do you need more information about settings?
We haven't read EMH LZQJ-XC meters for a while and I can't remember the serial port settings.
Data is not correct. Try to change the baud rate to 4800. Problem is for the serial port settings.
EMH LZQJ-XC - Strange problem
Hi,
It seems that meter is returning something, but it's not correct data. Check your serial port settings that they are same on the meter what they are in Moxa.
Try connect without Moxa. Then check Moxa settings.

Nothing Changes

We realized, that our EMH can
We realized, that our EMH can't run using rs232. We have to change protocol to rs485, and it's start working.
Thank you for help :)
