4 1. General Information The UDL250 is a compact long distance reader of the UHF type with an integrated antenna. The frequency range is factory-set and depends on allowed regulations for the particular region (see also Transmission Frequency in chapter 1. Technical Data ). The UDL250 has been specially developed for contactless identification of objects within a reading range up to 4 m. The most innovative feature of the UDL250 is its intelligent antenna concept, where the polarization of the antenna can be adjusted in four different ways (circular: RHCP or LHCP and linear: horizontal or vertical). This individual adjustment allows reliable reading and writing of unfavorably positioned UHF transponders (ISO C / EPC Class1 Gen2). The large and easy to see LEDs signalize positive identification for the user. 4

9 5. Interfaces 5.1 RS485 Most RS485 buses require termination resistors across the conductor pair. The need for termination has to be checked for each installation. Especially for high data rates, steep edges or long cables termination resistors are absolutely mandatory. Only both ends of the main cable, i.e. at the first and the last device, require termination resistors, additional resistors excessively load the drivers. The resistor value matches the cable s differential mode characteristic impedance (in most cases Ω). Attention! This termination resistor (terminator, 120 Ω) is factory built-in into all UDL250 and has to be deactivated if necessary (see also chapter Basic Setup > enable 485 termination within the configuration menu WebConfig ). The factory setting of this termination resistor is on. At the RS485 bus you need fail-safe biasing containing a pull-up and a pull-down resistor on the cable which are both built-in into the UDL250. The fail-safe biasing provides a known state in which there is no active driver on the bus and is therefore absolutely mandatory regardless of data rates and length of cables. The pull-up and pull-down resistors can only be activated together with the termination resistor (within WebConfig). 9

11 5.2 LEDs and Beeper The standard settings for the LEDs and the beeper are as follows: LED/Beeper Action Status UDL250 Yellow LED blinking field is switched off constantly on field is switched on Green LED blinking successful reading/writing of a transponder Red LED constantly on malfunction Beeper beep tone successful reading of a transponder Table 5.2.1: Function LEDs and Beeper (factory settings) Note: The LED characteristics may be different to those described above due to changes in configuration. 11

12 6. Mounting For mounting on walls or ceilings deister electronic provides the ball joint bracket LRM1 (accessory) or the base plate for mast mounting LRM3 (accessory) as an ideal supplement. For further details concerning accessories refer to chapter 10. Accessories. 6.1 Wall mounting with flexible pivot LRM1 For mounting on walls or ceilings the the ball joint bracket can be mounted directly onto the UDL250. With the LRM1 the reader can be positioned in many directions. Both mounting plates of this device are connected via ball bearing to a rotatable axis. Fixing the correct position is carried out with a hexagon spanner. Figure 6.1.1: Mounting with flexible pivot LRM1 Figure 6.1.2: Mounting with base plate LRM3 12

13 6.2 Mast/Tube Mounting with base plate LRM3 Mount the base plate LRM3 directly onto the back side of the UDL250 using the two supplied M6 screws with washers. Then mount the mast in the desired direction onto the LRM3 with a hose clamp. 6.3 Function Principle and Environmental Influences The reader sends a high-frequent carrier signal. A transponder which is located within the area of this transmitted carrier transmits the signal back with its own transponder data in a modulated way. This very weak signal is being analyzed by the reader. Because of the particular small-bandwidth and the high carrier frequency within MHzrange this system is almost fail-safe. Nevertheless the range of the reader can be negatively influenced. The following list shows what to pay attention to: 1. The reader must have visual contact to the transponder. There must not be any walls or other devices between reader and transponder. Reading through plastic film, card board, papers or glass windows may be possible in some cases, but will reduce the reading range depending on the condition of the material. 2. Water, ice and snow will absorb the carrier signal. Therefore the installer should take care, that the front of the reader as well as the transponder can not be covered with water, ice or snow. 3. Reflexions within the surrounding of the reader can influence the reading result in a negative way. Therefore the reader should be mounted as free-standing as possible. We strictly discourage from sunk-in installations. 13

19 7. Get Connection Preparations Connection via USB will create a virtual serial COM Port and will therefore consequently ask for installation of the appropriate drivers. This driver installation is described in the according instruction manual of the SNG SNG3 Interface Converter Figure 7.1.1: Picture of SNG3 The interface converter SNG3 (optional, see chapter 10. Accessories ) can be used for connecting a reader to a host/pc via USB. Powering of the reader is carried out as well by the SNG3 (in case this is connected to a power supply unit itself). For this a special wall power supply is available (optional, also see chapter 10. Accessories ). The drivers needed can be found on the CD within delivery.

20 8. Commissioning and Test Software RDemo The software program RDemo is specially designed for testing purposes. It is a helpful tool for reading out data from and writing data into the memory of a transponder. The current RDemo version can be found at: deister RFID Portal 8.1 Installing RDemo For installing RDemo double click the folder RDemo and select rdemo172.exe (or the equivalent higher version delivered with your product): Please follow the installation instructions. After successful installation start RDemo. 8.2 Port setting Get connection In order to establish a connection between the UDL250 and RDemo the according COM Port has to be adjusted within the program. Select the communication port of the UDL250 from the menu Port as shown below: Figure 8.2.1: RDemo Port setting 20

21 Click on button debus in order to open the window RDemo : debus : Figure 8.2.2: RDemo debus button Figure 8.2.3: RDemo debus configuration In order to have the reader detected please proceed as follows: 1) Set baud rate to all. 2) Click on button Detect Device(s). 3) After successful search the UDL250 will be shown in the list of detected devices. 4) Select device from list. 5) Click on button Set As Current Device. 6) Close window. 21

22 In order to check the communication between UDL250 and Host/PC click on the Version button (see red circle below). Then a version information received -message will be shown in a yellow pop-up bubble in the lower part of the window: The data exchange concerning the communication between RDemo and the UDL250 can be viewed within the window Monitor. In the standard configuration (i.e. factory settings) the device is set in Trigger Mode. This means the device waits for a Trigger On -command for switching the RF-field on and a Trigger Off -command for switching the RF-field off. These software commands are sent to the device using RDemo (separate buttons for Trigger on and Trigger off in the left part beneath the main menu bar). 22

23 9. Configuration Software WebConfig WebConfig is a program which allows configuration of the UDL250 to some extent. It can easily be reached from RDemo using the according button beneath the main menu bar (see red circle below): Figure 9.1: RDemo WebConfig Button Clicking on WebConfig will automatically close RDemo. A few seconds later WebConfig displays the current configuration of the UDL250 which contains device information about the version as well as basic settings, such as read mode, RF power settings and frequency settings. Closing WebConfig will automatically restart RDemo again. Figure 9.2: WebConfig Start Window 23

24 Alternatively, WebConfig can be started without using RDemo. To do so copy the file WebConfig.exe from the supplied CD into a suitable directory on your local drive and then open with double click. Configuring the UDL250 has to be carried out as follows: Step Configuration Software WebConfig Reader UDL250 1 connect reader to SNG3 (see Figure 7.1.2), connect SNG3 to PC via USB cable, connect wall power supply to SNG3 2 start configuration software WebConfig 3 select USB Serial Port 4 click on Device Search addresses 5 software searches for the reader which is connected to the selected COM Port 6 after successful search the reader found will be indicated 7 current reader configuration will be read 8 configuration menu will open 9 configuration can be modified by user 10 transfer changed configuration to the reader by click on Apply Changes 11 reader will store the new configuration within its internal non-volatile memory 12 end connection by clicking Offline 13 program will be closed by File - Exit Table 9.1: Configuration Steps for UDL250 24

In case there are more tags, the reader has to execute an anticollision algorithm. It is also possible to configure the reader to single shot mode in which the read signalling for the same transponder is only done once or after a timeout defined by parameter tag timeout. anticollision: Operating mode in case there is more than one tag in the field single shot: Operating mode for reading tag data in case there is only one tag in the field. The tag data will be transmitted again after the time period specified in tag timeout. tag timeout / ms (for read mode single shot only) Break between transmission of transponder data within single shot mode. After this timeout has expired reading the same tag will be signalled again. RF power / dbm This value defines the radiated power for the antenna in dbm. The maximum output power of the antenna is 30 dbm (1 W E.R.P.; see also Table Antenna Power Table ) 26
