1.0 Introduction to the DuraPoint OEM Module
Thank you for purchasing the DuraPoint OEM Module (DOM), the durable
pointing device designed to operate in harsh environments. The module has been
designed to be reliable, rugged and easy to integrate. It is the ideal computer cursorcontrol solution for industrial computers, process automation systems, industrial
keyboards, vision inspection systems, and military computers.
The DOM can easily be sealed into a system to create an interface impervious to
water and dust. Once properly sealed into a system, the DOM is designed to meet
NEMA 4X, 6P, 12 and 13 standards.
The DOM requires less than 1.250” (includes UL gap requirements) of mounting
depth (less than comparable trackballs or joysticks) allowing it to be integrated into
tight, cramped spaces. The module's slim mounting profile frees valuable space for
other system components or enables system size reduction. The module is unaffected
by mounting orientation: it can be mounted horizontally, as in a desktop industrial
keyboard; vertically, as in a process control panel; or any angle in-between. This
gives system designers maximum flexibility with product design and ergonomics.
The DOM incorporates Interlink Electronics' VersaPoint Pressure-Pointing
technology. Directional control is achieved by applying finger pressure in the
direction of desired movement to the mouse button. Speed is controlled by altering
the amount of applied pressure. The result is smooth cursor movement in any
direction, from a precise crawl to a screen-crossing zip. VersaPoint technology
has no moving parts to break or wear out, thus delivering reliable, trouble-free
cursor control.
DuraPoint, with no moving parts to break or wear out, is completely maintenancefree. Designed and manufactured with ruggedness and reliability in mind,
DuraPoint delivers “mouse” lifetimes in excess of 10 million actuations.
®
Before using or installing the DOM, please take a few minutes to carefully
review this integration guide.
Special
The DOM has two flexible circuits that electrically connect to the
Note:
PCB. One connects to the shielding layer and the other connects
to the pressure sensor. Care should be taken during handling and
installation of the DOM to protect these tails against kinking or
tearing, which could permanently damage the module. The DOM'sPCBisESD (electro static discharge) sensitive. Please use properstaticsafeguards when handling the module.

2.0 Operating the DuraPoint OEM Module
DuraPoint is designed to be easy and intuitive to use. The mouse button
controls the cursor direction and speed while the two click buttons control
the primary and secondary click functions.

2.1 Using the Pressure-Sensing Mouse Button
The DuraPoint OEM Module’s pressure-sensing mouse button converts the
touch of your finger into smooth cursor movement. To move the cursor, or
device being controlled by the DOM (e.g., a closed-caption camera), place your
fingertip on the center of the mouse button and rock it in the direction you
want the cursor to move. You can move the cursor in any direction - the DOM
has full 360° directional control. A light touch will produce precise cursor
movement. Increases in pressure will increase the speed - the harder you press,
the faster the motion.

DuraPoint Integration Guide
2.2 Clicking and Dragging
To Click
The click buttons, located on either side of the mouse button, incorporate
pressure-sensitive sensors to detect “clicks”. These sensors have no moving
parts to break or wear out, leading to long lifetimes. The left button on the
DOM is equivalent to the left mouse button and is used as the default primary
button. The right button is equivalent to the right mouse button (the default
secondary button). You can interchange the operation of the buttons in the
Windows Mouse Control Panel, if desired (e.g., for left-handed users).
To Drag an Item
Simply press and hold the primary button while moving the cursor with the
mouse button. Release the primary button to complete the drag operation.
Some users find it easier to swap click buttons and use the right click as the
primary button, allowing fore-finger cursor control with middle-finger clicking.
If your computer has Windows installed, you may wish to practice this
technique by playing the game of Solitaire.

3.0 INTEGRATION NOTES
3.1 Mounting and Sealing the DuraPoint OEM Module
The DOM is designed to be blind mounted or front mounted into a variety of panel
Its rugged stainless steel construction and rubber buttons enable it to be
types.
mounted in the harshest environments - direct water spray, dust, dirt, grime, oil,
food products and most cleaners and solvents will not affect its operation.
Additionally, custom bezels can be fabricated or molded to allow integration
into devices such as machine control panels or industrial computers. For more
information on custom bezels, please contact Interlink Electronics Product Support.
Before placing the installed DOM in the field, verify the seal of
Special
the DOM to the bezel/enclosure. Improper sealing, in wet
Note:
environments, could result in damage to the DOM or system.
Suggested Panel Cut-out with Standard Female Faceplate
If you purchased the DOM with the standard female faceplate, designated by the
VP25X0 series, see Figure 7.06 for details on the suggested mounting cut-out
and fastener locations.
Suggested Panel Cut-out with Standard Male Faceplate
If you purchased the DOM with the standard male faceplate, designated by the
VP25X2 series, see Figure 7.07 for details on the suggested mounting cut-out
and fastener locations.
Suggested Panel Cut-out without a Faceplate
DOM models without a faceplate are designated as the VP25X1 series. The rubber
keypad has been adhered to the DOM and should not be removed. When mounting
the DOM, the suggested clearance for the cut-out around the mouse button and
click buttons is 0.05” (1.3 millimeters). See Figure 7.05 for details on the suggested
cut-out and fastener locations.
Page 4
DuraPoint Integration Guide
Mounting the DuraPoint OEM Module
To panel mount the DOM without sealing, all that is needed is a panel designed
with the necessary cut-outs for the faceplate/mouse and click buttons and four or
more fasteners (e.g., PEM studs, edge clips, hole clips, heat stakes, etc.). No other
live electric parts may be within a half inch (0.500”) of the components inside of the
DuraPoint. DuraPoint must be installed into a suitable enclosure. When installing
the DOM, the mounting fasteners should be tightened evenly to allow proper
seating. Over torque on the bolts should be avoided, as this could damage the
DOM. With proper seating and tightening, a liquid-and-particulate resistant
interface can be created. The DOM should be grounded through either of the two
upper PCB mounting studs as shown in Figure 7.08. When mounting the DOM
without a faceplate, the flexible shielding layer circuit should be connected to the
support plate. Simply wrap the circuit over the mounting hole nearest the circuit,
run a fastener through the mounting hole, and tighten the fastener down. Figure 7.08
details the location of the shielding circuit.

Sealing the DuraPoint OEM Module
Some integrators may want to completely seal the DOM into a system.
By following the instructions below, a NEMA 4X/IP66 seal can easily be obtained.
Sealing the DuraPoint OEM Module with RTV Sealant
RTV silicone sealant can be used as a sealing material. Before starting installation,
be sure to clean the panel and faceplate/rubber keypad thoroughly with isopropyl
alcohol. Integrators may also find that some panel/bezel materials will need to be
primed with a silicone primer to obtain proper adhesion. To seal the DOM with
silicone sealant, apply a thin bead of sealant to the top of the faceplate/rubber
keypad on the outer edge of the faceplate/keypad. Sealant should also be applied
around the four mounting holes on DOMs with female faceplates and on DOMs
with no faceplate. If mounting without a faceplate, minimize the amount of sealant
applied to prevent lumping near the active buttons, which could adversely affect the
DOM's performance. Alternately, sealant can be applied around the perimeter of
the module and the mounting holes after it has been installed into the bezel or panel.
For the best possible seal, apply the sealant to both the top of the faceplate/ keypad
before installation, and around the perimeter of the module after installation.
Sealing the Male-Faceplate DuraPoint OEM Module
The DOM with male-faceplate option is sold with a foam-rubber sealing gasket.
The gasket is designed to seal the DOM into a system. As detailed above, RTV
sealant can also be used as a sealant material. To seal the male DOM into a
panel, place the gasket in between the DOM's faceplate and the panel face.
Then tighten down the mounting studs using care to tighten them evenly and
in a cross-wise pattern. Six mounting studs are attached to the DOMs male
faceplate. Use care not to overtighten the mounting bolts, as this could damage
the DOM or cause the gasket to extrude from the sides.
3.2 Electrical Interfacing to the DuraPoint OEM Module
The DOM can be connected to either a Microsoft -compatible serial interface
(RS232C) or PS/2 mouse port. Before installing the DOM, verify that your
system meets these requirements:
A system running Windows 3.0, 3.1, XP, 7 or newer, or operating
system with Microsoft-compatible mouse driver via serial or
PS/2 mouse port
Workstation or any other system (e.g., an X-Terminal) with a PS/2
mouse port

DuraPoint Integration Guide
RS232C Serial-Interface Connections
The following table shows the pin-out for RS232C serial-data connections to the
J1 interface header. The J1 header is the 10-pin, double-row 0.1” center header on
the back of the DOM's circuit board. Also shown are the connections for standard
9-pin and 25-pin DB-style serial connectors. Five lines are needed for an RS232C
serial interface. See Figure 7.08 for details on the J1 pin-out convention.
* See Figure 7.13 for details on the DB-9 pin-out convention
** See Figure 7.08 for details on connecting the cable shield
The DOM uses standard Microsoft-compatible serial-data format (detailed information on this data format is given in drawing VPDP-DOM120). In order for the
DOM to properly communicate to a system, a Microsoft-compatible mouse driver,
such as the Windows native mouse driver, will need to be installed (see the
DuraPoint User's Guide). Once the DOM is connected and the system restarted,
the DOM should operate properly.

5.0 TECHNOLOGY
How the DuraPoint OEM Module Works
The DOM's innovative design features no moving parts the patented pressuresensitive sensor used in VersaPoint technology replaces the troublesome
mechanical assemblies (optical encoders, wheels, rollerballs, etc.) found in
conventional mice and trackballs.
When finger pressure is applied to the DOM's mouse button, the pressure is
transferred to the pressure-sensitive sensor located under the button. The sensor
is divided into four directional zones (up, down, left, right). The pressure
distribution over the four zones determines the direction of cursor movement.
This same sensor also controls the speed of cursor movement a light touch
moves the cursor at a precise crawl while increases in pressure will cause the
cursor to move faster.
When pressure is applied to the DOM's click buttons, it is transferred to a
pressure-sensitive sensor located under the click buttons. The change in pressure
is detected by the DOM's electronics and is interpreted as a click activation. The
click buttons' pressure-sensitive technology have no moving parts to break or
wear out.
