Data-bussing and multiplexing can be complex and aggravating, but F.R.E.D. (Frustrating, Ridiculous, Electronic, Devices) can help solve the mystery behind it. In this program, Dave Hobbs brings his 30+ years of experience to show you how the electronic modules communicate with each other and help you tackle this tough issue and save diagnostic time.

Video Clip:

Dave uses hands-on demonstrations with the Snap-On MT2500, the Vetronix Tech2, and the Mastertech to explain data bus layouts, voltages, wiring and baud rates. He tells you what to do when your scan tool says “no data” or its display flashes. Dave explains the difference between a “UART data bus” and a “class 2 data bus” and the difference between loop and star configurations.
