6. Setup and Wiring

6.1. Transmitter Battery Installation

The 4-button remote control requires a 12V 23A battery (not included). To install:

1. Gently slide open the battery cover on the back of the remote.
2. Insert the 12V 23A battery, ensuring correct polarity.
3. Slide the battery cover back into place until it clicks securely.

6.2. Receiver Antenna Connection

The included antenna coil should be soldered to the 'ANT' pad on the receiver module for optimal range and performance. Ensure a secure connection.

6.3. Receiver Wiring

Connect the receiver module to your circuit using the following pins:

• +V: Power input (DC 3.3-5V)
• GND: Ground
• D0, D1, D2, D3: Digital output channels. These pins go HIGH when activated by the corresponding transmitter button, depending on the set working mode.
• VT: Valid Transmission indicator. This pin goes HIGH when a valid signal is received.

7. Operating Modes and Learning Process

The receiver module supports three working modes: Momentary, Toggle, and Latched. You must set the desired working mode before pairing the remote control.

7.1. Setting Working Modes

The receiver module has a small 'Learning Button' (also referred to as 'Key' or 'Code Button'). Press this button a specific number of times to select the desired mode:

Figure 7.1: QIACHIP Receiver Learning Button and Mode Settings. This image highlights the learning button on the receiver module and lists the number of presses required for each mode: Press Once for Momentary Mode, Press Twice for Toggle Mode, Press Three Times for Latched Mode.

• Momentary Mode (Inching Mode): Press the learning button once. The output is active only while the corresponding transmitter button is pressed. Release the button, and the output turns off.
• Toggle Mode (Self-Lock Mode): Press the learning button twice. Pressing a transmitter button once turns the output ON. Pressing the same button again turns the output OFF.
• Latched Mode (Interlocked Mode): Press the learning button three times. Pressing one transmitter button turns its corresponding output ON and simultaneously turns OFF any other active outputs. Only one output can be ON at a time.

7.2. Pairing the Transmitter (Learning Code)

After setting the desired working mode, you can pair the transmitter:

1. Ensure the receiver is powered on.
2. Press the receiver's learning button the required number of times for your desired mode (e.g., once for Momentary, twice for Toggle, three times for Latched). The LED on the receiver will blink, indicating it's in learning mode.
3. Immediately press any button on the 4-button transmitter. The receiver's LED will blink rapidly and then turn off, indicating successful pairing.
4. Test the remote control to confirm the pairing and selected mode.

7.3. Clearing All Paired Codes

To clear all previously learned codes from the receiver (e.g., when changing remotes or resetting):

1. Press and hold the receiver's learning button for approximately 8 seconds.
2. The LED will blink and then turn off, indicating that all stored codes have been successfully cleared.

8. Advanced Features: Group Control (ID Switching)

The QIACHIP system supports group control, allowing one remote to control multiple receivers by switching between different IDs. Each remote has 10 IDs (0-9), and each ID can be paired with up to 4 receivers, allowing control of up to 40 receivers in total.

Figure 8.1: Remote Control ID Switching. This image illustrates how to switch the remote's ID. Holding down button A and pressing button C switches the ID upwards (0-9). Holding down button A and pressing button D switches the ID downwards (9-0).

Figure 8.2: Remote Control Group Control Function. This image depicts a floor plan with multiple rooms, showing how one remote control can manage up to 40 receivers across 10 different ID groups (0-9), with each group controlling 4 receivers.

To utilize group control:

1. Switching IDs: To change the remote's active ID, hold down the 'A' button and press the 'C' button to switch the ID upwards (0-9). Hold down the 'A' button and press the 'D' button to switch the ID downwards (9-0). The remote's display will show the current ID.
2. Pairing Receivers to Specific IDs: When pairing a receiver, ensure the remote is set to the desired ID. The receiver will then respond only to commands from the remote when it is set to that specific ID.

9. Maintenance

• Keep the remote and receiver clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid dropping the devices or subjecting them to strong impacts.
• If the remote's range decreases significantly, replace the battery.
• Store the devices in a cool, dry place when not in use for extended periods.
