I'm having a problem with RS485 communication. My devices are connected to a Reliable MachProcom and the MachProcom is counting UART Framing Errors. When I'm looking at data on the line I see that the packet that create problems are sent from my devices but when I remove the MachProcom I don't see any problems on communication. My devices are using 1/8 load 3.3V RS485 drivers and the MachProcom is using a 1/4 load 5V driver. Also, when I use a different transformer for the MachProcom communication is working well without error.
I have take a look at my device's supply and the 3.3V seems to work fine.
