Work with a NFC programmer (LT-NFC)
Change the DALI address on the NFC programmer. After modification, batch parameters can be written to the driver.
1.Read the LED driver
Power the programmer by using the USB cable, then select “NFC Driver Settings” and press “OK” button. Next, keep the programmer’s sensing area close to the NFC logo of the driver to read the
driver parameters.
Before you begin setting the parameters of the driver on the NFC programmer, please make sure the driver is powered off.
NFC logo of the driver
On the home page of the programmer, press the “ ” button to select 【 Ready to Write】, then press the “OK” button. After the screen displays “Ready to write...”, please keep the programmer’s
sensing area close to the NFC logo of the driver. When the screen displays “Write succeeded”, it means the parameters have been successfully changed.
3.Write to the driver
2.Change the driver parameters (DALI address)
On the home page of the programmer, press the “OK” button to edit DALI address. Then, press “ ” button to adjust the parameter values and press “ ” to select the next needed value. After the
parameter values are modified, save them by pressing the "OK" button. Note: (1) The DALI address range: 0-63.
Use the NFC Lighting APP
Scan the QR code below with your mobile phone and follow the prompts to complete the APP installation (According to performance requirements, you need to use a NFC-capable Android phone, or an
iphone 8 and later that are compatible with iOS 13 or higher).
Use your NFC-capable phone to read the driver parameters, then set the DALI address, PWM frequency, other parameters, or set the advanced DALL template depending your needs. Save your
settings and hold your phone close to the driver again, so the parameters can be easily written to the driver.
Read/Write the LED driver
1.Read the LED driver
On the APP home page, click【 Read/Write LED driver】, then keep the programmer’s sensing area close to the NFC logo of the driver to read the driver parameters.
Before you begin setting the parameters of the driver on the NFC programmer or via the APP, please make sure the driver is powered off.
2.Switch the dimming interface
On the page of “Edit parameters”, click 【Dimming interfaces】to switch to the needed dimming interface: DT8 CT (DT8 1 channel), DT6 CT (DT6 2 channels), DT6 DIM (1 address for 1 channel /

Write/Read on the NFC programmer
1.Connect to the NFC programmer
Enable Bluetooth on your phone and power the NFC programmer first. Then press the button on the programmer to switch to “BLE Connection” and press ”OK” button to wait for Bluetooth connection.
On the APP home page, click【Write/Read on NFC programmer】—【Next】to search for the programmer and connect to it.
2.Read the LED driver
On the “Programmer information” page, choose any solution for editing. Then keep the programmer’s sensing area close to the NFC logo of the driver, to read the driver parameters.
Connect the NFC programmer to your phone and read the driver parameters with your phone. After editing the solution in the mobile App, you can sync it to the NFC programmer and write advanced parameters to
mass LED drivers.
5.Write to the LED driver
When the programmer screen shows “Sync ... succeeded”, click “BACK” button to return to the home page and switch to the “APP Solutions”, then press the “OK” button to access the optional solu-
tions. Select the corresponding solution by pressing the “ ” button, then keep the programmer’s sensing area close to the NFC logo of the driver. After this, the advanced solution can be written to
a large number of the same model drivers.
