KEBA XE020 RFID Module Manual

3.2 Installation process

Factory pre installation: In the KEBA operation panel, the antenna is fixed on the inside of the front panel, and the evaluation unit is installed on the back shell of the panel. Users do not need to disassemble or assemble by themselves.

Third party equipment installation: It is necessary to open holes to fix the antenna module and ensure that the evaluation unit is away from strong electromagnetic interference sources (such as frequency converters and switch power supplies).

Interface, connector, and wiring guide

4.1 Connector Distribution

The XE 020/A evaluation unit and XE 020/ANT antenna module both have the following interfaces (refer to the original diagram):

Coaxial antenna cable connectors (positions 1 and 3) - used to connect the evaluation unit with the antenna module.

Status LED connectors (positions 2 and 5) - lead out three color LED signals to the front panel.

RJ45 socket (evaluation unit only, position 4) - connected to the EXT0 interface of the control panel, providing power and serial communication.

4.2 Pin Definition

Status LED connector (3-core): No specific pin list provided, but the original text states that using three unshielded core wires (corresponding to red, green, and common/ground) is sufficient.

RJ45 socket (XE 020/A side):

4：Data-

5：Data+

7：+12V DC（±5%）

8：GND

Other pins (1, 2, 3, 6): No connection.

Key constraint: The cable connecting the RFID module to the operation panel (OP 3xx) must be shielded and not exceed 1 meter in length. The grounding effect at both ends of the shielding layer is optimal.

4.3 Coaxial antenna cable

Maximum allowable length: 300 mm. Exceeding this length will cause RF signal attenuation, reduced reading distance, or even complete failure.

Use the recommended KEBA original cable (order number 71352) or the same specification 50 Ω/75 Ω coaxial cable.

4.4 Key points of EMC cabling

The original text emphasizes that electromagnetic interference is a common cause of intermittent system failures and is difficult to reproduce. The following measures must be taken for the XE020 module:

Shielding: The entire cable from the RFID module to OP 3xx is shielded.

Grounding: Ensure that the grounding point inside the control cabinet is reliable and avoid parallel laying with power lines (motor, frequency converter output).

Spacing: Coaxial cables should be kept away from high voltage and high current lines as much as possible, with a minimum spacing of no less than 100mm.

ESD protection: During installation or maintenance, first contact the grounded metal to release static electricity, and then touch the module circuit board.

Power supply and electrical characteristics

The XE 020/A evaluation unit is powered by 12V DC ± 5% through an RJ45 interface provided by the control panel. Its power consumption is not explicitly stated in the document, but can be estimated to be around 1-2W based on the maximum RF transmission power (250mW) and logic circuit.

It should be noted that this power supply belongs to the Safety Extra Low Voltage (SELV) standard, which complies with EN 60950-1, and therefore allows operators to touch the interface.

Configuration: DIP switch and hardware address

When there are multiple RFID modules in the same system (such as multiple operation panels sharing a controller), a unique hardware address must be assigned to each module. The XE 020/A is equipped with a 4-digit DIP switch (only two of which are actually used, and up to 4 types of addresses can be configured).

6.1 DIP Switch Setting Table

Adr0 Address Value Description

0 0 binary 00, corresponding to hexadecimal 17H (the original table may be incorrect, according to actual logic)

1 1 binary 01, 16H

2 2 binary 10, 15H

3 3 binary 11, 14H (factory default)

Note: The original table states "DIP switch Adr0" and "Address", and lists 0017H, 0116H, etc. In practical engineering, the DIP switch should be turned to the desired position and the module should be restarted (powered off and then on) to make the settings effective.

6.2 Precautions for Multimode Group

If only one RFID module is used, the factory default (address 14H) can be retained.

Address conflicts can cause the controller to be unable to distinguish RFID data from different operation panels, resulting in random recognition failures.

Status LED indication and fault diagnosis

The three color LED at the front of the operation panel is the primary basis for on-site troubleshooting. The following table summarizes the meaning and handling measures of LED status:

LED status meaning, reasons/solutions

Red (flashing) RFID card not recognized or unauthorized card damaged; Card data format error; Distance too far (over 40mm); Duoka Conflict

Green (about 3 seconds) recognition successful and normal

Contact KEBA for repair if the permanent red firmware is not running or there is a hardware malfunction

Permanent orange not connected to the controller. Check if the RJ45 cable is properly plugged in; Check the power supply of the controller and the configuration of the EXT0 interface

The LED is turned off and connected normally, and the standby state is normal. It will only briefly light up when the card approaches
