On fusion 16 channel SPDT relay, a dual communication port, I want to use a Wifi adapter in one port and the second port an RS-485 adapter hood to a different circuit board (control by wifi through the fusion a metering device). Let me know if it possible or I have to use an i2c converter to RS-485.
You say you want an RS 485 adapter installed in the second Fusion communication interface port so you can connect to a different circuit board. What is the second circuit board?
I will say it is not possible to connect to the Fusion controller through the WiFi interface installed in the first port and then through that connection communicate to another device connected through RS 485 on the second port. The Fusion board cannot act like a WiFi to RS 485 adapter if that is what you are looking to do.
