EHS5T RS485 writes gibberish on the serial prot ASC1 | Telit Cinterion IoT Developer Community

Hello,
The "EHS5T RS485" writes gibberish on the port without any user Software on it.
I connected a display to it, and after restarting the box it writes "y5e" on the output, and the longer I keep it connected the more characters appear on the display.
I was able to measure the signal with an oscilloscope, and it looks like propper/intended serial communication
I use a 4 wire connection for the display (RX, TX, Vcc and GND)
I connected a "virgin" Module out of the box to the display. I didn't change anything about the configuration. There is also no user software on it.
Any idea how to turn that off, or is a Firmware update planned to fix that?
Hello,
I have sent you the 00.000.55 firmware.
I didn't have a possibility to test the terminal with oscilloscope.
Regards,
Bartłomiej
Thank you.
I have donlwoaded it already.
Unfortunately, I am busy with another project right now.
But I'll tell you my experience with the new firmware as soon as possible
Hello,
unfortunately, uograding the firmware didn't change anything, the behaviour is still the same.
This might be a bug which should be told the developers about?

Hello,
I a meantime I have also tried with some EHS5 RS485 terminal, I have connected signal analyzer and didn't find anything unusual.
I think that you should report it to your distributor or local Gemalto office. Maybe your devices are faulty and need to be examined and maybe replaced.
Best regards,
Bartłomiej
