CONFIGURATION254.7 USB READER CONFIGURATIONThe USB interface is compatible with:Windows 98 (and later) IBM POS for WindowsMac OS 8.0 (and later) 4690 Operating SystemUSB Start-upAs with all USB devices, upon connection, the Host performs several checks bycommunicating with the USB device. During this phase the green LED on the deviceblinks and normal operations are suspended. Two basic conditions must be metbefore the USB device is ready to read codes, the correct USB driver must be loadedand sufficient power must be supplied to the reader.For all systems, the correct USB driver for the default USB-KBD interface is includedin the Host Operating System and will either be loaded automatically or will besuggested by the O.S. and should therefore be selected from the dialog box (the firsttime only).If the Host supplies sufficient power to the reader, the start-up phase ends correctly,the LED stops blinking and the reader emits the beep OK signal.If the Host does not supply sufficient power to the reader, a dialog box will appear onthe Host and the reader will be blocked (LED continues blinking). In this case,disconnect the USB device cable at the Host (LED stops blinking), connect andpower-up an external supply to the USB cable then reconnect the USB cable to theHost and close the dialog box. The reader emits the beep OK signal. You can nowread codes. At this point you can read the USB interface configuration codeaccording to your application. Load drivers from the O.S. (if requested). Whenconfiguring the USB-COM interface, the relevant files and drivers must be installedfrom the USB Device Installation software which can be downloaded from the webpage http://www.scanning.datalogic.com.The reader is ready.
