DIAS Automotive Electronic C234 NFC Reader Module
Product Overview
Product Introduction
In LPCD mode, the near field communication module can wake up the NFC device
on the vehicle side when the NFC card or mobile phone is near, and then enter
the standard Polling mode. When a matching card is detected, the polling mode
is activated. LIN informs VKM and CAN informs BCM to open or close the door.

Assembly Introduction
The C234 is placed inside the door handle and do not require extra fixing. Figure 2 3 show the installation positions.
Operation Instruction
The NFC valid card is placed near the NFC module, and the NFC module transmits information to the ECU with SE at the end of the car through LIN, and unlocks the car after the NFC card is certified.
Setup Up
Before the module can start normally, it is necessary to prepare a power
supply, a valid NFC card, a wire harness, and a LIN communication tool. In
addition to connecting the NFC reader module, the wiring harness also needs to
connect to the LIN communicat ion tool. After the power supply is powered on,
if the current is about 20mA, the NFC module is started. Figure 3 1 shows the
following.
Swipe Care
Place a valid NFC card close to the NFC module, as shown in Figure 3-2.
Query Version
LIN Communication
-
