SECTION 2. INSTALLATION
This section describes the cable connection, the Windows Plug and Play Setup, and the physical
mounting of the unit.
USB CONNECTION
Since the USB IntelliHead is supplied as an OEM product, the installation and system integration
will be unique for each application. The reader module must be attached to an appropriate
connector which, in turn, connects to the USB port or hub. The pin numbers for the 5-pin
connector are shown in Figure 2-1.
Pin numbers and signal descriptions for the cable shown in the illustration are listed in Table 2-1.
The connector is a Molex 52021-0500; one of the recommended mating connectors is Molex
53048-0510.

WINDOWS PLUG AND PLAY SETUP
On hosts with the Windows operating system, the first time the device is plugged into a specific
USB port, Windows will pop up a dialog box, which will guide you through the process of
installing a device driver for the device. After this process is completed once, Windows will no
longer request this process as long as the device is plugged into the same USB port. The device
driver that Windows will install for this device is the driver used for HID devices and it is part of
the Windows operating system. When the dialog box pops up, follow the instructions given in
the dialog box. Sometimes Windows will find all the files it needs on its own without giving any
prompts. Other times Windows will need to know the location of the files it needs. If Windows
prompts for the file locations, insert the CD that was used to install Windows on your PC and
point Windows to the root directory of the CD. Windows should find all the files it needs there.
MOUNTING
Refer to the appropriate Appendix in this document and/or to the Magnetic Card Reader Design
Kit for complete mounting details.
