Node-red-contrib-modbus and MAX485 TTL to RS485 converter


Is it possible to use MAX485 TTL to RS485 converter in node-red ?
converter link:
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

done this configuration
config-pin p9.13 uart
config-pin p9.11 uart

You can run it. The modbus node works perfectly.
