Rock PI 4A & Node Red & USB dongle

Hello!

Im trying to transfer from RPI4 to Rock PI 4 with my project and have got a problem within this porting

Now Ive already installed Node-RED version v3.0.2, Node.js version v14.20.1 on Linux 4.4.154-116-rockchip-g86a614bv15b3 arm64 LE
I have got rock pi 4a v1.47

In Rock my node-red project hasnt started yet
I supposed what the problem in drivers
So I started trying to test transfer data via terminal first

So in my attempts in transfering and receiving data via terminal using USB-RS485 dongle I have the following results:

  1. I can send string and receive that too
  2. When I send hex data I receive unrecognized data. In RPI this test successfully passed

And at this point I stopped unfirtunally

Please help
