hello!
I have an esp32 based Kincony A24 panel. I need another modbus port besides the original one. it has a uart port for the 4G cellular adapter. i use this to control a uart pwm generator. is it possible to connect the pwm panel and the modbus adapter to the uart Tx and Rx connectors in parallel, but connect the 5v voltage separately, only to one panel at a time? I would normally use the modbus, but if necessary, I disconnect it with one of the relays, turn on the pwm, modify what I need, then disconnect it and reconnect the modbus panel.
