UDL120

1. General

The 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.

5. Mounting on Forklift

5.1 Mounting of UDL120 with steel sides (Protection Set 1)

5.1.1 Mounting steel sides

The 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):

5.3 Mounting UDL120 onto steel sides

Mounting 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):

6. Function of LEDs

The 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 off

yellow LED is permanently on: standard operating status; device is ready to read;

RF field is switched on

green LED shortly flashes: shows successful reading of a transponder

red LED is active: shows a general malfunction within the system

7. 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 Baud
Data bits: 8
Stop bits: 1
Parity: 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.

UDL120

7.2.2 Configuration mode of Bluetooth™ module

Configuration of the Bluetooth™ module takes place via Bluetooth™ interface. The
following parameters can be adjusted:

 transmitting power of the Bluetooth™ module

The 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 command

ATO<Enter>

needs to be sent to the module. After any configuration process a Reset is required.

7.2.3 Transmitting power

The 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 command

ATS541?=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>
