Node-RED USB

Hello everyone,

I am trying to control an battery inverter (SOYO) via the GX with node RED. Venus large is version 2.91.


For the control of this inverter, I use a RS485 to USB converter which is attached to a USB HUB on the GX.

I use serial communication node on this port e.g. ttyUSB3 with 4800 baud and sent cyclically 1/sec some data to the SOYO, this works as expected.

My problem is the GX seems to *add* some data output to this port and this in fact destroys my messages.

My question is: how can I forbid Venus OS to access this port in this special case?


regards

Venus OSNode-RED
