Calibration procedure below.
*Note: Not all rotator choices support auto-calibration.
Manual Calibration
Now click on the VOLTS button (You can close the message that opens, it's just a reminder of these
instructions). The sensed voltage from the rotator control box is now displayed on the LCD.
Manually increase your azimuth and watch the voltage on the LCD. The first number on the top line is
the voltage for azimuth. Stop moving if this voltage goes higher than 5 volts! If it passes 5 volts
then you need to turn the Output Voltage Adjustment knob on the back of your rotator control box
to decrease it. See your Yaesu Manual for instructions.
The goal is to increase the AZ to it's maximum and adjust the voltage to keep it between 4 and 5
volts. The maximum azimuth for the G5500 is the red 90° mark on the right side of the guage, on the
G5400 the maximum is the 180° on the right of the guage. If the voltage ends up below 4 volts then
for highest accuracy you should increase it by turning the Output Voltage Adjustment on the back of
your rotator control box. When the voltage is between 4 and 5 volts at the maximum azimuth then
you can move on to the elevation setting.
The elevation is set the same way as the azimuth. Increase the elevation and watch the LCD to make
sure it does not pass 5 volts. Again adjust the voltage to get it between 4 and 5 volts at the maximum
elevation (180° on both the G5400 and G5500). *If your G5500 is limited to only 90 degrees elevation
then choose "Yaesu G5500 360/90" in the rotator selection. Then during the manual calibration you
can move the elevation to 90 degrees instead of the full 180.
Finally, when the both azimuth and elevation are at their maximum positions and the voltages are
between 4 and 5 volts, press the SET MAX button.
Now move both AZ and El all the way back to the minimums. Press the SET MIN button.
Your S.A.T. is now calibrated to your rotator control box. Press the STOP button to exit Voltage mode.
You need to do this calibration process every time the S.A.T. boots. Just kidding! *The calibration only
has to be done once ;).
* Note that if anything changes in your rotator configuration, such as changing the rotator
cables, you should calibrate the S.A.T. again.
