Modbus decoder

Modbus frames over a UART or RS-485 line, decoded.

Add-on video coming

No video of this feature yet. It will be filmed on our own scopes, working end to end, before it goes on sale.

What it does

Decodes Modbus RTU and ASCII frames over a UART line. It can measure the line's own baud rate and decode at it, including rates that are on no standard list, and it takes an RS-485 pair as A minus B.
