External CD-ROM Drive
3.3 External CD-ROM Drive
An external CD-ROM drive can be attached to the 8580/8590. It is connected via
the USB port.
Important: When connecting an external USB CD-ROM drive which has its
own external power supply the 8580/8590 must be disconnected
from the power supply. The CD-ROM must be powered up simul-
taneously or after the 8580/8590 as otherwise this can cause start-
up problems, malfunctions, or even the destruction of the device.
Keep in mind also that not every device classified as a USB CD-
ROM is a proper USB CD-ROM drive. Only use devices approved
by Psion Teklogix to ensure the device is fully compatible.
3.3.1 Operation
The CD-ROM drive port is provided via USB. The drive, which is supplied in a
separate housing, is connected to one of the sockets on the back of the 8580/8590.
Depending on the model, the external drive is powered either via the vehicle-mount
connecting cable or via a separate, external power supply.
If USB has been activated in the BIOS, the CD-ROM drive is automatically
recognized and made available by the BIOS.
The CD-ROM drive is bootable once it has been properly installed. To boot from a
CD-ROM, insert a bootable CD and start the system.
Note: In the BIOS USB CD-ROM must be entered as a boot device.
3.3.2 Resources And Drivers
Resources for the USB port are pre-defined in the system architecture and
automatically managed by the BIOS.
Drivers for the various operating systems need to be supplied by the drive
manufacturer (order if necessary).
3.4 USB Stick
You can connect a USB stick to the 8580/8590 with a USB-A connector.
