Model: EB1 / EB2 / EB5
Manual www.ltech-led.com

Product Introduction
Adopts a two-in-one control method combining Bluetooth 5.2 SIG Mesh wireless protocol and DMX512 protocol, providing greater flexibility and convenience for engineering applications. 4-zone dimming touch panel with DMX512 master control, adjusted via a touch color ring. The function area keys can be set as single-zone or multi-zone panels through the APP. Paired with the L-Home APP, it enables control over lighting on/off, dimming, and color adjustment. When paired with a smart gateway, it supports a variety of control methods, including rich cloud scenarios, cloud automation, and local automation. Supports local scenarios. It can be controlled without a gateway and remains operational even when the network is down, ensuring faster and more stable performance. Compatible with European standard back boxes and Chinese national standard 86 back boxes.

For a better product experience, it is not recommended to use both the wired DMX output of the panel and the wireless

Bluetooth driver at the same time.

Please try to avoid placing the wireless drive next to large metal objects or using it in a space with a lot of metallic

media, so as not to have the signal interfered with and affect its usage.

If there are more than 32 DMX decoders connected, a DMX signal amplifier should be added, and the signal amplification should not be continuous for more than 5 times. When there are more than 32 DMX/RDM decoders connected, if it is necessary to modify their parameter settings, one RDM signal amplifier can be added, or after the parameter settings are completed, 1 to 5 DMX signal amplifiers can be added.
When the signal recoil effect affects the usage due to reasons such as a long signal line or the quality of the wire, you can try to connect a 0.25W 90-120 terminal resistor at the end of each signal line to solve the problem.

For DIM, four partitions cycle every 4 addresses. For CT and CT2, four partitions cycle every 8 addresses. For RGB, four partitions cycle every 12 addresses. For RGBW, four partitions cycle every 16 addresses. For RGBCW, four partitions cycle every 20 addresses. Follow the indication in the above diagram, and so on.

For Use With The L – Home APP.
1. Register an account Scan the QR code below with your mobile phone. After completing the APP installation according to the prompts, you can proceed with the login/registration operation.
Scan the QR code to download the APP iOS/APK
2. Pairing operation After a new user creates a family on the APP, click the “+” button in the upper – right corner of the [Rooms] interface to add a device. Select “LED Controller” from the device list. Then, choose the partition control mode as “Single – zone” or “Multi – zone”, and select the control type as RGB, RGBW, or RGBCW. Follow the on – screen prompts to complete the addition.
13

3. Applications of single-zone and multi-zone On the “Room” interface, click the added touch panel to enter the [Control] interface. In the single-zone mode: Click “Bind Area”, select the device to bind, and you can bind lights or light groups.Brightness shortcuts can be set to four percentage levels: 25%, 50%, 75%, and 100%.Click the “…” button in the scene, select “Bind Scene”, and you can bind ” Save Current Scene”, “Local Scene”, or “DALI Scene”.Single-click a card to execute the scene; long-press the card or click “…” to unbind the scene. In the multi-zone mode: Zone actions: Short-press to turn on, select, or deselect a partitioned zone.Long-press to turn off the zone.Click the “…” button in the zone to bind devices, activate the current zone, or customize the name. Scene actions: Single-click a card to execute the scene.Long-press the card or click “…” to bind or unbind the scene.
14

4. Be bound by the remote control The touch panel EB1 can be bound to the B1 remote control, the EB2 can be bound to the B2 remote control, and the EB5 can be bound to the B5 remote control. Each partition of the remote control corresponds to each partition of the touch panel. After binding, the remote control zone will control the load of the touch panel.
15

5. Local scene Create a local scene: Switch to the Smart page, click “+” in the upper right corner to create a local scene, and after setting the execution action, you can realize the local linkage of Bluetooth devices. Binding local scenes: On the control details page, click on the corresponding key, and set the binding scene. Once saved successfully, a short press of the button will immediately execute the bound scene.
16

6. Cloud scenes and automation Make sure that a smart gateway, such as Super Panel 12S, has been added to the family. Cloud scenes: Switch to theSmartinterface and click “+” to create a cloud scene. After setting the execution action, remote linkage can be achieved. Automation: Select “Automation” in theSmartpage and click “+” to create automation. You can choose local/cloud execution mode,and set trigger conditions and execution actions. When the set trigger conditions are met, a series of device actions are automatically triggered to achieve remote linkage. Note: Touch panels can be set as trigger conditions or as execution actions.
17

Restore To Factory Settings
Method 1: After the EB – series (EB1/EB2/EB5) touch panel is connected to power, use a SIM – card – eject tool to long – press the reset key on the back of the panel for 6 seconds (see Figure 1). When all the indicator lights on the panel flash and then go out, it indicates that the factory settings have been restored. Method 2: First, make sure that the device is properly powered on and in an online state. Then, open the L – Home APP, find the device, and enter its settings page. Click the “Delete Device” button (see Figure 2). When the system prompts “Deletion successful”, it means that the device has been successfully restored to its factory settings.
