9 USB driver installation

To use the online and the database mode the ARE H9 HF is connected via USB

to a host PC. Before the USB connection could be used a USB to RS232 bridge

drive has to be installed.

If you want to use the USB-HID interface the standard keyboard driver is used.

Insert the driver disc supplied with the ARE H9 HF into your CD-Rom or DVD-

Drive of the host PC you want to use with the pocket reader. Connect the ARE

H9 HF with the supplied USB cable to a free USB port of your PC (USB1.1 and

USB2.0 ports are supported).
