Subject: Re: [EE] RS-485 analyzer/sniffer? I've used a logic analyzer like the thech-tools DigiView to watch a 485 bus directly. No 485 receiver required since one wire or the other is 5V serial data. Also, RealTerm can capture serial data and display it in hex. I use an FTDI TTL-232R-5V-WE cable to get TTL or similar level data into a USB comm port.
