Installation
Connecting the device
The following paragraph describes all steps to get the device connected. The RS232-cable is fixed at the
device.
Switch off of computer or PLC
Information about switching and shut down the computer /PLC correctly you´ll find inside the manual. This
should always been done because of safety reasons before a new device is going to be installed.
Connecting the device cable to the PC/PLC
1. Connect the 9pin SUB-D to the interface cable to the suitable socket of the PC/PLC. If you are using a
RS232-USB-cable converter, the converter cable is just plugged into the 9-pin Sub D of the standard
RS232-cable.
2. The Standard RS232-cable allows either to use a separate Power supply (NT Hx5x0, 50110676), or using
via PIN9 of the cable a power supply inside the PLC.
3. Plug in the power supply into a power socket 110-230VAC (not necessary when PIN9 is used).
4. To switch „On“ the device please press the ‚OK‘ key. As soon the display shows the functions selection
the device is ready to use. The GREEN LED (above left edge of display) is ON, too.
5. With the black marked keys the function is selected and with the yellow marked key activated. Settings for
data output, code types etc. can be set in the ‚system‘ area (right yellow key).

How is the best way to scan or read?
Here we give you some advices for best case scan or read operations:
The Scanner should be held with alight angle to the code. (Don´t used it in 90°to the Code, because you get
total reflexion and read failure.)
The red LED-Line is an aimer and should be held onto the code. The Scanner cannot identify the label
correctly, if it´s not complete within the red line.
The red LED-Line is smaller and narrow if the device is close to the code. Codes with small and thin bars
should be read with a smaller distance, for larger codes the distance should be bid enough to have the
Complete code within the red line.
For reading the RFID tag, the environment should have less possible metal and the device should be held
very close above the tag.
The antenna of the device should cover over 70%.of the tag to have good conditions for reading it.
The read characteristics are printed on page 8
Test barcode
The printed code is to test the functionality of the scanner, module(bar)
width is 0.5 mm (20 mil)

Functions
Function SCAN Barcode
The device reads and decodes 1D / 2D Codes of the released types in a distance up to 350mm after
activation (Press Button) and displays the info. Depending on the setting an output via interface of the code
information is possible, too. 1D / 2D codes are printed typically in ASCII and read so as well. A data output is
possible in HEX-format too, with the suitable parameter. All parameter settings can be found in the sub menus
inside the system area/barcode (see menu structure). The configuration can be done alternatively with the pre
defined codes (see configuration).
Function SCAN RFID
The device reads transponder in distances up to 450mm after activation (Press Button) und displays the Info.
Depending on the setting an output via interface of the information is possible, too. The data is always stored
in hexadecimal format on the transponder. A data output is possible in ASCII-format too, but Data / Serial no.
only. Error messages are shown in the display and (Parameter) possibly transmitted via interface. Up to
32Bytes (depends on tag!) of data (8Blocks) can be read in one operation. All parameter settings can be
found in the sub menus inside the system area/RFID (see menu structure).
Function EDIT RFID
The device allows you to write data to transponders up to 400mm after input via key board or via telegram
from Host, but always after Activation (Press Button). Parameter dependent an output via interface is
possible. Messages and errors are shown in the display. The max. amount of data for writing is similar to read
max. 32Byte (8Blocks), depends on tag. The input can be (parameter!) either in ASCII or HEX-Format. All
parameter settings can be found in the sub menus inside the system area/RFID (see menu structure).

Short description HFU 4520D Leuze electronic Page 10
Function SCAN Barcode and EDIT RFID
This special and unique function reads a released Barcode /2D (3 trials) per activation (Trigger button) and
writes the read information to the next Transponder into the defined memory slot(parameters). Start of Write
op again with trigger button. In any case the device comes back with a message (success/ failure) onto
Display / Interface. The sequence is fixed, an interrupt is only possible with C. All parameter settings can be
found in the sub menus inside the system area/barcode and RFID (see menu structure).
Function SCAN ALL
This function is a combination of the functions READ Barcode and READ RFID.
The device tries after activation first to read a released transponder, 3 trials (Info on Display) and
after that without a success a released Barcode. Again the info is on the display and on the interface.
After the 3 trials without any success an error message (NoRead) is shown on Display / interface.
After a successful read (Transponder or Barcode) the operation is finished and can be started again with
activation. All parameter settings can be found in the sub menus inside the system area/barcode and RFID
(see menu structure)
Further supported possibilities for interaction with the PLC system via command and interface
1. Text message onto Display
With the command “MD“ and directly attached ASCII-characters you can send a message with 16
characters onto the display of the device. The message has to be receipt at the device with pressing the
Trigger button/OK before the device is back in work mode
2. Accoustic signal
With the command „BP1“ / „BP2“ you can activate a deep /high acoustic signal for 1s, for an easy feed
back from PLC to device
3. Function pre select
All provided functions of the device can be pre selected from the PLC with the command „FC“(with
acknowledge from user) or “FCx”(without any action from user) , e.g. to proceed application dependent
process steps.
The command “FC1(x)” selects function“SCAN Barcode“, “FC2(x)” function „SCAN Barcode-EDIT RFID“;
“FC3(x)” the function“SCAN RFID“, “FC4(x)” function“EDIT RFID“ and “FC5(x)” the function“SCAN All“.
The selection is shown on the display and when using “FC” activated with the Trigger button.
4. Pre defined Data for writing onto Transponders
With the command “W“ you can send Data for Writing onto any transponder via interface to the HFU,
reasonable in combination with the function selection FC4 (x).
Pressing the Trigger button activates the Write operation directly.
The command structure of the W- command is the same as known from the fix mounted RFID-devices.
5. Ready signal / alive sign
With the command “?” a ready signal and the state of the device can be detected. The device comes
back (activate Messages) with “SFC0” when no function is selected, “SFC1” with selected function 1
(SCAN Barcode) etc. (see no 3.)
Note: Please combine Commands and Data (characters or numbers) directly (without space between) into
One single telegram, enclosed of the telegram prefix/suffix

Diagnostics and trouble shooting
Typical errors and their possible causes are described in the following list as well as tips for their elimination:
1. Is the device connected to a suitable power supply from the PC– means device and PC/PLC should be
connected to each other before switch ON. The external power supply should have 6VDC/1A
2. If you use the separate Power plug please check the connections
3. Make sure the interface cable is fixed correctly at the PC/PLC. Details for the interface are printed usually
in the manual of the PLC/PC.
4. If you checked all steps before and the device is still not ready, change the power supply to another one.
5. Please check the used interface at the device and your PC/PLC are compatible. Information about that is
printed in the PC´s /PLC´s manual.
6. 1D / 2D Code: Please check the quality of the Barcode / 2D Labels, and the correct symbologies are
released. Damaged labels (scratched, dirty or crinkled) can cause hardly readable or not readable codes.
7. RFID: Please check the settings for RFID and check the transponder type with your supplier. If the
settings are correct the transponder can be defect as well- try another one if possible.
8. Now you checked most possibilities. For further support please contact the Leuze Service.
