RIVES ECHNOLOGY
The pins of the 9-way D type connector will have a different function depending
on whether the Omni is configured for an analogue or a digital type input
device.
The mating 9-way D type connector (socket) should
always be fitted with gold contacts and a suitable
backshell with locking screws. These locking screws
should be used to mechanically hold the connector
firmly in place.

Analog Signal Levels

The analogue inputs are compatible with PGDT JC200BR3K1Y and Flightlink
I5X1SSG251020 joysticks.

Pin 1 - Joystick speed

This is the joystick signal that determines the forward/reverse component of
wheelchair movement. The joystick has a 1.8KΩ resistor in series with the speed
output as shown below. All voltage levels apply to the actual joystick output, i.e.
no load values. The Omni has an input resistance of 100KΩ to 0V.
For optimum performance, The Omni 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 Omni will
assume a fault condition.
