1 General
The Mini Joystick USB (MJ-USB) is an input device that is used as a mouse input for
computers or similar devices.
It allows you to control the
mouse pointer of the computer.
It’s a small joystick which can
be handled with small strength
(<10 gr.) and little movement.
The ergonomic shape is ideal to
take the joystick in your hand
and control the device with the
thumb.
The joystick can be adjusted to
any individual need and
possibility of the user by
adjusting the settings in the HMC USB Configurator.
We can install the joystick in the right position through the mounting kit.
You can adjust the joystick to the needs of the user via 2 extra knobs – a ball and a
cup. In combination with mounting kit it’s possible to manipulate the
Mini joystick by finger, hand, tongue, chin, etc.
The possibility to adjust the sensibility of the handle makes this
product the perfect solution for people suffering from muscular
dystrophy, but other classes of users could also use it.
The joystick is completely protected against moisture, which makes
it suitable to use as chin control.
When the joystick isn’t used for a longer period, you can place a
hood over it. This gives an extra protection.

2 Operation
2.1 Introduction
The MJ-USB is a joystick module that can directly be connected to a computer equipped
with a USB port.
Copies of this manual are available from HMC International in either written or disk (Adobe
PDF) format. Copies of this document should not be made without the express permission
of HMC International NV.
The operation of the MJ-USB varies depending on programming. For a complete
description of the system we refer to the HMC USB Configurator Manual – 0052-8001a. It
is the responsibility of the manufacturer or local dealer to ensure that only the relevant
sections of this chapter are included in the operating guide of the device to which the MJ-
USB is connected.
Please read this chapter carefully - it will help you to keep your devices reliable and safe.
2.2 General
The MJ-USB needs to be connected to an USB port. The following picture shows an
example.
2.2.1 Handling
Avoid knocking the joystick. Never drop the joystick.
When transporting the joystick, make sure the hood is used to protect the joystick. Avoid
damage to cables.
2.2.2 Operating Conditions
The joystick uses industrial-grade components throughout, ensuring reliable operation in a
wide range of conditions. However, you will improve the reliability of the joystick if you
keep exposure to extreme conditions to a minimum.
Do not expose the joystick to damp for prolonged periods. If the joystick becomes
contaminated with food or drink clean it off as soon as possible.
