1. General InformationThe UDL250 is a compact long distance reader of the UHF type with an integratedantenna. 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 polariza-tion 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 unfavor-ably positioned UHF transponders (ISO 18000-6 C / EPC Class1 Gen2).

The large and easy to see LEDs signalize positive identification for the user.

5. Interfaces 5.1 RS485Most 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 res-istors excessively load the drivers. The resistor value matches the cable´s differential mode characteristic impedance (in most cases 100...120 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 9.1.2 “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 absolutelymandatory 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).

6. MountingFor 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 LRM1For 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 lo_udl250_wi_en V14/05/09


6.2 Mast/Tube Mounting with base plate LRM3Mount 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 InfluencesThe 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 MHz-range 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.

7. Get Connection – PreparationsConnection 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 SNG3.

7.1 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.

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).

read modeThis parameter defines, if the reader expects only one tag in the antenna field or if there may be more tags within the antenna field. 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 tagin 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 / dBmThis 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 9.1.3 “Antenna Power Table“)
