1. GeneralThe UDL120 contains an integrated RFID antenna for contactless reading of transponders fixed on storage racks. It has been designed for fast and faultless electronic recognition of goods in transit (i.e. palettes) and is increasingly used within electronic inventory control systems.The reader can be mounted directly onto the fork carrier between the forks of a forklift. Due to its flat mounting height (installation depth only 40 mm) any contact to the transported goods will be avoided. Solid metal side cheeks (optionally available) prevent the reader from being damaged by the transported goods and mounting on buffers provides reasonable absorption of shocks and vibrations.An ultrasonic sensor in the middle of the housing (optional) detects loading of the forks and reports it to the control unit (terminal) of the forklift. This will initiate a reading process, in which the transponder fixed to the storage rack is being read.The reading result contains the defined storage position of the rack using the specific transponder ident number and is instantly being reported to the terminal.The communication between antenna and terminal can either be carried out via cable using RS485 or wireless via Bluetooth™.For power supply the reader requires a power connection directly at the fork carrier of the lift mast (12...24 V/DC).As this document is solely intended for application of the UDL120 on forklifts, the metal steel sides (Protection Set 1) are included into all image presentations for reasons of clarity.4lo_udl120_io_en V08/07/09 UDL120

5. Mounting on Forklift 5.1 Mounting of UDL120 with steel sides (Protection Set 1) 5.1.1 Mounting steel sidesThe mounting of the two steel sides has to be carried out by the customer between the forks of the fork carrier with 3 countersunk head screws (M6) on each side (drilling distances see per drawing):10 lo_udl120_io_en V08/07/09 UDL120Figure 5.1.1: Mounting UDL120 with steel sides (Protection Set 1)

5.3 Mounting UDL120 onto steel sidesMounting of the reader onto the metal bracket has to be carried out using the 4 supplied screws (DIN 912 cylinder head bolt, allen head screw) and the according washers.For additional absorption of shocks and vibrations the reader has to be mounted onto the steel sides using the four supplied buffers (see picture below):14 lo_udl120_io_en V08/07/09 UDL120Figure 5.3.1: Mounting UDL120 onto steel sides
6. Function of LEDsThe function of the three LEDs on top of the reader (see also 3.1 Picture) is as follows:yellow LED is blinking: standard operating status in trigger mode;device is ready to read;RF field is switched offyellow LED is permanently on: standard operating status; device is ready to read;RF field is switched ongreen LED shortly flashes: shows successful reading of a transponderred LED is active: shows a general malfunction within the system7. Communication 7.1 Communication via deBus protocol (standard)The standard way of communication between UDL120 and Terminal (via CB2, CB1, SNG etc.) is carried out using the deBus protocol on the RS485 bus. 7.2 Communication via Bluetooth™ (optional)Contactless communication is carried out via Bluetooth™ with an Ezurio BISM2 module.This module provides a virtual serial interface for communication with the reader using the Bluetooth™ SPP (Serial Port Profile). The serial interface of the PC has to be configured as follows:Data rate: 115200 BaudData bits: 8Stop bits: 1Parity: none 7.2.1 Connecting to Bluetooth™ module (pairing)A Bluetooth™ stick for the PC is needed, which contains SPP (Serial Port Profile). The according Bluetooth™ module can be found by scanning all available Bluetooth™ devices. The reader reports with „UDL120 #xxx“. The required PIN for the Bluetooth™ connection is „0000“ (default setting). As long as the memory capacity of the Bluetooth™ module is sufficient, the module stores the identification of the communication partner so that the pairing process does not have to be repeated.V08/07/09 lo_udl120_io_en 15UDL120
7.2.2 Configuration mode of Bluetooth™ moduleConfiguration of the Bluetooth™ module takes place via Bluetooth™ interface. The following parameters can be adjusted:transmitting power of the Bluetooth™ moduleThe Bluetooth™ module needs to be switched into the configuration mode first in order to change any of its settings. In order to do so, three consecutive quotation marks („!!!“) need to be sent with a time difference of 100 ms between each other using the Bluetooth™ interface.This can be done for example by help of the Windows program Hyperterminal, which can access the Bluetooth™ module on the PC using the virtual serial interface.In order to leave the configuration mode the following commandATO<Enter>needs to be sent to the module. After any configuration process a Reset is required. 7.2.3 Transmitting powerThe Bluetooth™ module can be configured for a transmitting power between -27 dBm and +6 dBm. The current transmitting power can be requested by using the following command ATS541<Enter>Configuration of the transmitting power is carried out using the commandATS541?=m<Enter>The parameter m can be configured with a value between -27 und +6. Changed settings become active immediately but are only stored within the volatile memory. In case the module can not be accessed any longer due to an incorrectly adjusted transmitting power, the original value can be restored by switching the reader on and off.If all changes of the settings are correct, the configuration has to be transferred into the non-volatile memory by using the following command AT&W<Enter>16 lo_udl120_io_en V08/07/09 UDL120
