Hi,
Does some have any recommendations how to connect this adapter ?
converter link: https://roboticx.ps/product/max485-ttl-to-rs485/
library: node-red-contrib-modbus (node) - Node-RED
I found that it uses /dev/ttyS4
I connected it to UART4.
I am using Beaglebone green gateway
4.19.94-ti-r73
done this configuration
config-pin p9.13 uart
config-pin p9.11 uart
