SK81935-01
For optimum performance, The Omni2 should be calibrated for individual joysticks. The voltage swing of 1.2V is a nominal
value, actual values of between 1.1V and 1.3V will be accepted by a calibration sequence.
If the voltage swing with respect to Vpin3 exceeds 3.0V, then the Omni2 will assume a fault condition.

PIN 2 – JOYSTICK DIRECTION
This is the joystick signal which determines the turning component of powerchair movement. The joystick has a 1.8K
resistor
in series with the direction output as shown below. All voltage levels apply to the actual joystick output, i.e. no load values.
The Omni2 has an input resistance of 100K
to 0V.

PIN 3 – JOYSTICK REFERENCE
This is the joystick center point reference. The joystick has a 470
resistor in series with the reference output as shown
below. All voltage levels apply to the actual joystick output, i.e. no load values. The Omni2 has an input resistance of 200K
to
0V.

PIN 5 – DETECT
This pin should be linked to 0V inside the input device. This link allows the Omni2 to detect if the SID is connected. If the link is
not fitted, the Omni2 should be configured to ignore the absence of the link.
