does anyone have a schematic for an RS-485 signal tester. It would be nice to have data signal flash an LED (perhaps with a pulse stretcher so that brief activity is more visible), an "out of range voltage" indicator, an "open" and "short" LED, etc.
Has anyone built such a beastie? I know B&B Electronics sells one, but theirs seems minimal, and for the price ($180 US) I thought I might try to make one myself (more because I want to learn about RS485 than to save the $180).
