3.Configuration and setting
Please note: This manual is considered to be prelimiary.
In the standard configuration the device is set in “Trigger Mode“. This means the device waits
for a “Trigger On“ command to switch the RF-field on and a „Trigger Off“ command to switch
the RF-field off. These software commands can be sent to the device using RDemo software (to
be found on the CD which is part of the UDL5 package).
The UDL5 in its current version is EPC class1 gen2 complicant only.
3.1 Transmission protocol
The communication of the UDL5 is based on the “deBus” protocol. For integration into userdefined applications please contact your local sales and service center (see end of document).
First the USB driver has to be installed. The following steps show how to install the driver
under Windows XP (Windows Vista is supported as well):
•Connect the UDL5 via USB cable to a spare USB Port at your Host/PC
(USB cable as part of delivery of UDL5).
•Windows XP indicates the new hardware with the message
“Found New Hardware: HARVEMAC“.
•The “Found New Hardware Wizard“ will now be started automatically.
Select “No, not this time“ and click “Next“.
If this procedure failed, the search for new hardware can be started manually by click on:
“Start“ -> “Settings“ -> “Control Panel“ -> “System“ -> “Hardware“ -> “Device
Manager“. Select the USB device, marked by a yellow question mark.
