RFID Reader RFID 131
The RFID reader is an installable device for reading and writing to RFID card. Communica-
tion with other bus participants is established over the CAN bus or USB interface. The
reader is supplied with +24 V.
The RFID reader is installed in a cutaway of the control cabinet. The status LED in the
upper left corner blinks in a 1 s cycle and indicates the readiness of the device. With a CAN
message, it can also be controlled via the application.

4 Mounting Instructions
The following guidelines must be observed when installing the RFID reader:
- For installation with the screw-in brackets provided, it is recommended that the in-
stallation panel have a material strength of 3 mm. Material strengths from 1 to 4
mm are also allowable. The screw-in brackets can be tightened with a maximum
torque of 0.15 Nm. For this purpose, a 3x0.5 flat-tip screw driver is required.
- To avoid damage to the front, it is important to ensure that during installation, the
mounting surface clean (free of debris, uneven areas). Unevenness can lead to
voltages on the front or contamination from dust and water.
4.1 Mounting Position
Since very little heat is generated, no specific clearance is required.
Sufficient air circulation however, must be ensured so that no trapped heat can developed.

5 General Instructions
5.1 Ground
The RFID reader must be connected to ground through the assembly on the control cabinet
or over the connection provided. It is important to create a low-ohm ground connection, only
then can error-free operation be guaranteed. The ground connection should have a maxi-
mum cross section and the largest (electrically conductive) surface possible.
5.1 Shielding
To wire the USB interface, a USB 2.0 cable must be used. When using the CAN bus inter-
face, a shielded cable must be used. Noise signals can therewith be prevented from reach-
ing the electronics and affecting the function.
5.2 ESD Protection
Before any device is connected to, or disconnected from the reader, the potential should be
equalized (by touching the control cabinet or ground terminal). This will allow the dissipation
of electrostatic loads (caused by clothing/shoes).

RFID READER RFID 131
01.07.2020 Page 11
5.3 User Guidelines
CAUTION!
The RFID reader cannot always be operated with an interface (USB or CAN). Simulta-
neous operation is not supported and causes the reader to malfunction.
CAUTION!
The USB interface is not used to operate the device.
Here, as can be seen under "Electrical Requirements", an additional external voltage
supply is required.
Technical changes to the device, as well as improper use can lead to the loss of the
FCC license and generate interference, which can affect the function of nearby de-
vices.
Please note the national standardization when operating the wireless device.
Further information on the use, as well technical data can be found in the separate manual
for the RFID reader series. This can be acquired through the support.

6 CAN Bus
This section explains how to correctly configure and use the CAN bus. The CAN bus inter-
face is based on the CAN-Open standard according to EN50325-4. For the configuration,
the device ID and the data transfer rate must be set.
6.1 Node ID Assignment
Each CAN bus participant in the system is assigned its own node identification number
(Node ID). With this Node ID, data can be exchanged with other stations connected to the
bus. In a CAN bus system however, each Node ID can only be assigned once!

6.2 Number of CAN Bus Participants
The maximum number of participants on the CAN bus depends on the cable length, termi-
nation resistance, data transfer rate and the drivers used in the participants.
With a termination resistance of 2x 20 , a minimum of 100 participants are possible.

RFID 131 RFID READER
Page 14 01.07.2020
6.3 CAN Bus Data Transfer Rate
Various data transfer rates (baud rates) can be set on the CAN bus. The longer the bus line
is, the lower the data transfer rate that must be selected.
In delivery condition, the CAN Baud rate is set to 500 kbits/s.
The CAN bus transfer rate can be freely configured via DIP switch, if a device is ex-
changed or incorrectly configured, the DIP switch must be checked or set correctly.

6.4 CAN Bus Termination
In a CAN bus system, both end modules must be terminated. This is necessary to avoid
transmission errors caused by reflections in the line.
6.5 CAN Protocol
Each message contains up to 8 bytes. The data transfer takes place according to CiA
DS301. Several CAN messages may be necessary for one frame on the RFID reader.

6.5.3 Serial Interface
The data from and to the RFID hardware (2000 RFID - Request, 2200 RFID - Response)
are forwarded by the microcontroller from/via the serial interface. The protocol documenta-
tion of the HF-RFID Reader can be obtained separately from the support department. It
describes the complete communication processes.
6.5.4 Example Communication - Scanning Tags
Here a short communication example is shown which CAN messages are necessary to
perform a SCAN.
To read or write data from or to the RFID reader, the protocol must be transferred from the
HF-RFID reader via the CanOpen protocol.

Now the Scan Tags command should have been successfully sent to the firmware of the
RFID reader via the CanOpen protocol. To be able to read the response to the Scan Tags
command we have to read the response from the module. The response of the command is
provided by the firmware in the designated area (0x2200 RFID Response) in the object
dictionary.
An SDO upload must be initiated to read this data.
