Since the vast majority of installations of the DB42 will be utilizing the standard 2 inch saddles, that is the verbiage used in the instructions that follow.

  • Page 93 SECTION 16.0 TROUBLESHOOTING TIPS SteppIR antennas are all powered by stepper motors, hence the name. Stepper motors function by rotating the shaft a specific number of “steps” per revolution. The SDA 100 is simply counting the steps, of which for each step sequence there is a known length that the antenna is adjusting. If for some reason the anten- na gets out of calibration, the method for recalibrating is pretty simple.
  • Page 94 Again, be careful NOT to short the pins. Even if the controller is turned off, there is always voltage going to the pins with a SteppIR controller. We do this to “lock” the step- per motors, and minimize the need to calibrate the antenna on a regular basis.
