[amsat-bb] Yaesu G-5500 Elevation read

[jarda]

Hello Vincenzo,

the G5500 rotator requires 6 wires  for azimuth (connection between the 
control unit and the rotator unit) and another 6  for elevation. 3 wires 
are designed for motor power supply and 3 for voltage from the 
potentiometer (angle sensor). It seems that one (or more) of the three 
wires connecting the potentiometer to the control unit is broken. Then 
the rotor moves up and down correctly, but there is no signal about the 
antenna position.

The connection between the potentiometer and the control unit must be 
checked.

One wire is used as ground, the other one feeds the potentiometer and 
the third detects voltage from the potentiometer according to the 
rotation of the antenna.
