Note:
To avoid possible damage to one or both of the power supplies, do not supply
both internal power and external power to the controller. Power from two sources could
cause damage.
Using an Internal Power Supply (+5V to +12V) to JP3
Provide power directly to the controller using JP3 (Molex 22-05-3021). Use a mating 2-
pin connector and connect Pin 2 to power (b5V and +12V) and Pin 1 to the
return. (Mating connector is the Molex housing 22-01-3027 with 08-50-0114 contacts).
Using a Custom Serial Cable Design
When creating a custom serial cable connection, you can provide power to the controller
through JPI. Refer to Table 1 for more information on actual cable connections.
1.
Obtain a 7-pin Molex connector 51004-0700.
2.
Attach power and ground to the connector, (Pin 6: +5V to +12V, Pin 7: Ground).
Using an External Wall-Mount Power Supply
If you are using a standard 3M™ MicroTouch™ RS-232 serial cable (P/N 7310101),
consult your applications engineer for power supply specifications.
Mounting the Sensor
There are several methods for mounting the sensor depending on your application. If you
need instructions or recommendations from 3M Touch Systems on how to incorporate a
sensor into your design, refer to the
3M™ MicroTouch™ System 3nnnEX Integration
Guide
(P/N TSD-19-278). All 3M Touch Systems documentation is available from the

Turning On Your System
Before you turn on your touch system, ensure that all cables are connected properly and
that the controller is properly mounted. Be sure to tighten all cable connector screws.
To start up your system:
1.
Turn on your display and computer.
2.
Adjust the contrast and brightness to suit your personal preference and working
environment.
3.
Adjust the horizontal and vertical position controls on the display to center the image
on the screen.
Note for USB mode:
If the driver has been previously loaded, the controller will
enumerate and the PC will beep when hot plugging the controller into a USB port. When
disconnecting the controller, the PC will beep again.
