If you are powering your Mercury with a wheelchair battery, install the Mercury wheelchair power cable
(purchased separately from ATI) and make the power connections from the port on the wheelchair to the
Mercury AC Adapter/Battery Charger port.
To use the wheelchair joystick as an input device with your Mercury, connect the larger 9-pin connector of
the Wheelchair Joystick Cable (purchased separately from ATI) to your wheelchair ECU connector. Connect
the smaller 8-pin connector to the Mercury wheelchair/joystick port.
When your joystick is in switch/communication mode (see the documentation for your wheelchair
electronics), the joystick will move the mouse on the screen. If you want to add a switch to click the mouse
button, connect a single switch to the Switch 1-2 jack on the Mercury or to the auxiliary switch input on the
wheelchair ECU.
The normal setting for Joystick is
Move Mouse
. Moving the
joystick will start moving the mouse pointer slowly or
quickly, depending on the acceleration setting, and speed
up to the Speed Setting. A slower Acceleration Speed
allows finer accuracy when moving short distances. Faster
Speed and Acceleration allow quicker movement over
longer distances (or across the display).
How do I set up Mercury to work with my wheelchair
electronics?
