2. Mounting
The JSK-120 requires a 47mm diameter hole in the mounting panel. There is no
limitation on the panel thickness.
3. Connections
The JSK-120 uses the Vishay 981HE sensor and the wiring colours are somewhat
counter intuitive….
Green = +5V
Red = Signal
Yellow = Ground [0V]
These should be connected to the Pro-160 / 360 control board as follows.
4. Calibration
The Pro-160 / 360 should have the throttle setting / input mode set to “volt”.
If the center detent is being kept, joystick mode should be set to “on”.
The pot learn procedure should then be carried out as described in the
controller manual.
