I still have trouble.
I soldered a Pin into JMP1 so it is always connected to GND when using a Breadboard (what I use to test). The connections are the same as in Motoron M2U550 + Raspberry Pi 5 - #8 by Mael. The only change to connect two Motorons that I made is, the TX cable from the Pi goes into a seperate connector on the breadboard and from this I have a cable connected to each Motoron (Rx).
The python setup program works without an error. wenn I send “a 18” it says somthing in the lines of “setting Devicenummer to 18” so as you would expect it. (when I send those commands the TX is only connected to one Motoron at the time). And then when I want to check if it worked and send “i” it only says “Done” without listing any Motoron. I tried rebooting the Motoron (disconnect from Power) and sending “r” via the python program but the result from “i” doesnt change.
I decided that I dont want to use I2C for the Motoron.
What am I doing wrong?
