KEBA XE020 RFID Module Manual

Troubleshooting:

Measure the voltage of pins 7-8 of RJ45 with a multimeter: 12.1V is normal.

Check the signal line Data+/Data -: It was found that the shielded cable had virtual soldering at the joint.

After re soldering, the LED first turns red, then orange, and then turns off, returning to normal.

12.3 Case 3: Multiple operation panel address conflicts

Phenomenon: There are two OP 350 panels in the workshop, each with XE020 module. However, when swiping the card on panel A, it is sometimes interfered by the error prompt on panel B.

Reason: The DIP switches of both modules are factory default (address 14H), and the controller cannot distinguish them.

Solution: Turn the DIP switch Adr0 of the second module to "1" (address 16H), and configure the corresponding serial port channels in the controller program to solve the problem.

Integration suggestions with other systems

13.1 Software integration with KEBA controller

In the Kemro.view.standard development environment, the UID string of RFID cards can be read through the system API. The typical steps are as follows:

Initialize EXT0 serial port (baud rate is determined by firmware by default, usually 19200 or 115200).

Polling the receive buffer, when a card enters, it will receive a data frame in a specific format.

After verifying the integrity of the data, extract the card number and compare it with the local permission table to execute login or logout logic.

13.2 Access of third-party PLC or IPC

Due to the serial data output of XE020/A (via RJ45 Data+/Data -, essentially RS485 or TTL level), if it needs to be connected to the RS232/RS485 port of a standard PLC, level conversion may be required. Please refer to KEBA's "General Guide for RJ45 Cable Connections" for detailed pin timing diagrams. A simple approach is to purchase the original connecting cable (58033) and solder it to the DB9 connector according to the pin definition.
