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).
