1. Overview of Range
The Storm Trackball range (as fitted to the Storm 2200 keyboard) comprises a number of rugged
Trackballs utilising 38mm (1.5") balls. The units are designed for public access applications and are
available with either a black phenolic resin ball or a specially treated steel ball. Both types are available
with either
- auto-configuring PS2/USB output (standard product), or
- Microsoft compatible serial (RS232) output (to special order only).
Each unit has a self-adjusting seal around the ball which affords the unit an IP65 rating whilst ensuring
that the ball tracks smoothly and accurately under all operating conditions.
All units are further protected by a stainless steel ‘anti-vandal’ plate which transmits shock loads (for
example, due to abuse) directly to the stainless steel keyboard fascia, thus preventing damage to the
trackball assembly.
2. Configuration settings
There are no user-selectable configuration settings on the Trackball units.

4. Connection Formats
All units are fitted with two Molex 5046 headers to allow connection to the associated buttons and also to
the host computer. Cables are normally ordered separately to allow the user choice of interface. (See
Section 7 for ordering details). Note that earlier models can be factory configured with both buttons as
left click. In later versions this feature is user selectable with a jumper between the two Molex headers.
 P1 is the input connector for the buttons (6-way) and is always fitted.
 P3 is the output connector for USB and PS/2 protocols (6-way).
 P4 is the RS232 output connection for Microsoft serial protocol (6-way).
Either P3 or P4 are fitted, never both.
Table 1 shows the connector pin-out details:
Pin P1 Function P3 Function P4 Function
1 0V D-/ DATA Tx
2 Button 1(L) D+/ CLK Rx
3 0V TEST RTS
4 Button3 (R) +5V +5V
5 0V 0V 0V
6 Button 2(M) N.C. DTR
Table 1: Connector details
Please note that the TEST input is reserved for factory test only. On no account should a connection be
made to this terminal.
The Button inputs are pulled high within the unit to the 5V power supply via approximately 7k
Ω . Both
rising and falling edges of this signal are debounced for 30ms.

Since Trackballs are classified as Human Input Devices (HID) by the USB organisation, they implement
the low-speed USB specification. Therefore it is not necessary to shield the cable carrying the D+ and D-
signals, although it is highly recomended that you do so. In addition, it is recommended that the systems
integrator follows USB guidelines on wire gauge and twisted pairs.
In serial (RS232) modes, both RTS and DTR must be connected for the unit to operate correctly when no
5V supply is present. It is not sufficient to just connect RTS, unless the external 5V supply is present.

5. Frequently Asked Questions
Q. How are the various protocols selected on multi-protocol Trackballs?
A. The unit automatically selects either USB or PS/2 protocols on power-up without setting any DIP
switches.
Q. My Trackball wasn’t supplied with a driver disk. Is this correct?
A. Yes, our products are designed to work with resident drivers and do not require any further software to
be loaded.
Q. I have connected my Trackball to a USB port but it does not function. Why is this?
A. Ensure you do not have either Windows 3.1 / 95 or Windows NT operating systems- none of which
support USB even if your computer has the necessary sockets.
If you have Windows 3.1 / 95 installed, consider an upgrade to Windows 98. If you have Windows NT4
installed, consider upgrading to Windows 2000.
Q. Is any maintenance or adjustment required through the life of the product?
A. No, other than periodic cleaning with a clean, lint-free cloth, no maintenance is required. The electronics
are calibrated for life facture and require no maintenance.
Q. What happens if liquid is dragged around the ball in usage ?
A. The rear of the trackball incorporates a collar so that in the event of this happening any liquid is
channeled away from the trackball electronics.
Q. I have purchased a standard unit and am installing it in a kiosk where the right button function must
not be accessible to the user. How can I disable the right button ?
A. Remove the connection going to Pin 4 on connector P1.

6. Servicing
No routine servicing is necessary to the trackball product. The seal around the ball offers a high level of protection
to the internal mechanism and circuitry, making routine cleaning unnecessary.
In high-use applications the user may occasionally notice a slightly ‘lumpy’ feel to the ball. This is invariably a
small build-up of debris between the shafts and ball and may be removed by gently pushing against the ball whilst
rotating it. This has the effect of crushing the debris and moving it off the run-line between the ball and shafts. The
unit will then behave normally.
If the trackball requires cleaning in-situ, this can be carried out using a clean, lint-free cloth. Do not use solvents,
abrasives or other cleaning agents.
If the trackball has to be replaced, follow the following procedure :
1/ Remove both cable connections.
2/ Undo 4 M3 nuts and washers from the back of the trackerball unit.
3/ Remove the anti-vandal plate.
4/ Lift the entire trackerball unit and sealing gasket off the back of the keyboard.
5/ Fit new sealing gasket and trackerball unit.
6/ Refit nuts, torque to 50Ncm.
