How do I set up MiniMerc to work with my wheelchair
electronics?
If you are powering your MiniMerc with a wheelchair battery, install the MiniMerc wheelchair power cable
(purchased separately from ATI) and make the power connections from the port on the wheelchair to the
MiniMerc AC Adapter/Battery Charger port.
To use the wheelchair joystick as an input device with your MiniMerc, 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 MiniMerc 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 MiniMerc 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).
