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 stainless steel ball. Both types are USB output
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.

Configuration settings

There are no user-selectable configuration settings on the Trackball units.

Connection Formats

All units are fitted with two Molex 5046 headers to allow connection to the associated buttons and also to the host computer. 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 (6-way).

Table 1 shows the connector pin-out details:

Pin	P1 Function	P3 Function
1	0V	D-/ DATA
2	Button 1(L)	D+/ CLK
3	0V	TEST
4	Button3 (R)	+5V
5	0V	0V
6	Button 2(M)	N.C.

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 7kΩ. 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.

Frequently Asked Questions

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 or later
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. On later versions (not shown in picture) fit the supplied jumper to both pins.

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 and washers, and tighten evenly (ie fit all 4 nuts first snug before you start tightening),then torque in order 1-3-2-4 to 50Ncm.
