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.
The writing function “Transponder“ -> “Write“ can be used to write block data to an EPC
class1 gen2 transponder. To do so proceed as follows:
•Choose a tag type (please note: The current UDL5 version supports EPC class1 gen2
tags only), the serial number (EPC) of the tag, a predefined memory section and the
data to be written.
•Click on the “Write!“ button and present the EPC class1 gen2 tag within the RF-field.
The block data will be shown in the “Monitor“ window. RDemo indicates successful
writing with a “write successful“ message (in the “Monitor“ bottom state bar, see
below).
For more details concerning EPC class1 gen2 tag memory organisation see section
Additional tag functions like “Kill command“ and all others are not supported by the
current version of UDL5. Please consult the next sales and service center for details.
4.7 RDemo command builder
For sending a user-defined deBus command to the UDL5, the “Command Builder“ is a
useful tool.
•Go to “Special Functions“ and select “Command Builder“.
•Enter a user-defined deBus command string without dummy bytes, CRC and STOP
This paragraph refers to the document “EPCglobal™, Specification for RFID Air Interface”,
Version 1.0.9.
The tag memory is divided into four memory banks. Each memory bank consists of several
blocks, each block has the size of 2 bytes. The banks RESERVED, EPC and TID must always
be available, the USER bank is optional.
•RESERVED: Non-Volatile-Memory, this memory contains a 32 bit Kill Password and a
32 bit Access Password.
•EPC (Electronic Product Code): This bank contains the CRC-16 (cyclic redundancy
check), PC (Protocol Control) and EPC. The PC bits contain information about the tag,
e.g. length of the EPC. The EPC begins at block address 66 (dec), MSB first. In case of
a 96 bit EPC it has the size of 6 blocks.
•TID (Transponder Identification): The TID memory contains data about the
manufacturer. Tags may contain specific data within the TID memory, beginning at
block address 130 (dec), e.g. a tag serial number.
•USER: allows user specific data storage. The memory organisation is user-defined.
Hereby, deister electronic GmbH declares, that this equipment - if used according to the
instructions - is in compliance with the essential requirements and other relevant provisions
of the RTTE Directive 1999/5/EC.
