Hi Petr,
I've been working on the hardware a bit.
- I installed a small power supply module that maintains the voltage at exactly 30,0 volts (Tested with the "Fluke").
- The GND (output of the USB-RS485 adapter) connected to the GND of the PTA8D08 module.
- I tested at new all four listings you provided so far, but I don't see any difference.
-(I also did a test 'switching the A B connections...)
I wanted to do this first, to address both your and my concerns about the correctness of the electronic setup.
Tomorrow I will try to make a summary of the output you requested from the program or from the Linux system.
