![]() I took the switchbox and sensors apart and pulled the numbers off of all the chips I could see inside and have been trying to trace the wiring to get an idea of what goes to what. These sensors are a little more complicated than I was expecting, so I'm wondering if anyone out there has any background knowledge of the DRB III tool. My thought was I would plumb the signals into a simple microcontroller like an Arduino or even just a volt meter and figure out what angle corresponds to what output. I figured the sensors were probably typical 0-5V output or 4-20 mA like most lab style sensors you can find for data acquisition systems. I don't have a DRB III, but I have some background in sensors as I helped to set up the test department where I work and deal with sensors and DAQ equipment on and off. So the other day I picked up a Miller 6990 kit, which has the control arm bushing remover/installer, the caster fixtures (for gen 2 unfortunately), and the inclinometers and switchbox used by the DRB III to read caster. ![]()
