3. Setup and Installation
Device Components and Indicators
Initial Setup Steps
- Install Antenna: Screw the rod rubber antenna onto the CP26 converter.
- Connect RS232 Converter: Attach the RS232 converter to the CP26.
- Power On: Press and hold the 'KEY' button for approximately 1 second to power on the device. The blue light will blink three times, indicating a successful startup.
- Download App: For mobile phone verification, search for and download the 'DX-SMART' app from your device's app store.
- Enable Bluetooth & Location: Ensure Bluetooth and location services are enabled on your mobile phone.
- Connect via App: Open the 'DX-SMART' app, navigate to the homepage, and click 'Transmission' to search for Bluetooth devices. Locate 'RS232/485' and connect. A 'Connected' message confirms success.

4. Operating Instructions
Data Transmission Verification (Loopback Test)
To quickly verify the transceiver functionality and proper serial communication, perform a loopback test:
- Ensure the device is powered on and connected to the 'DX-SMART' app.
- Use the included jumper cap to short-circuit the TX (Transmit) and RX (Receive) interfaces on the RS232 connector. Important: This short-circuit must be performed after the device has successfully started up. Failure to do so will result in verification failure.
- In the 'DX-SMART' app, send data. If the sent data is received and displayed correctly, it confirms successful transceiver operation and serial communication.
Baud Rate Configuration
The default factory baud rate is 9600 bps. You can change the baud rate by double-clicking the 'KEY' button. The number of flashes of the 'WORK' status light indicates the current baud rate:
- Once: 2400 bps
- Twice: 4800 bps
- Three times: 9600 bps (Default)
- Four times: 19200 bps
- Five times: 38400 bps
- Sixth: 57600 bps
- Seven times: 115200 bps
The default serial port parameters are 9600bps/8/n/1 (baud rate/data bit/no parity/stop bit). Note that the DX-BT27 does not support software flow control.
5. Maintenance
To ensure the longevity and optimal performance of your DX-CP11 adapter, follow these maintenance guidelines:
- Keep Dry: Avoid exposure to moisture or liquids, which can damage internal components.
- Clean Gently: Use a soft, dry cloth to clean the device. Do not use harsh chemicals or abrasive materials.
- Temperature Control: Operate and store the device within the specified working temperature range of -40°C to +85°C.
- Protect from Impact: The device features a durable housing that is dustproof and anti-static, but avoid dropping or subjecting it to strong impacts.
- Proper Storage: When not in use, store the adapter in a safe place away from direct sunlight and extreme temperatures.
6. Troubleshooting
If you encounter issues with your DX-CP11 adapter, refer to the following common problems and solutions:
- Device Not Powering On: Ensure the USB connection is secure and providing adequate power (5V). Check the 'KEY' button for proper function.
- No Bluetooth Connection: Verify that Bluetooth and location services are enabled on your mobile device. Ensure the 'DX-SMART' app has necessary permissions. Try restarting both the adapter and your mobile device.
- Data Transmission Failure: Perform the loopback test as described in Section 4 to confirm the transceiver's functionality. Check serial port parameters (baud rate, data bits, parity, stop bits) for correct configuration. Ensure the TX and RX pins are not accidentally shorted unless performing a loopback test.
- Intermittent Connection/Poor Range: Ensure the antenna is securely attached. Minimize physical obstructions between the adapter and the connected device. Check for potential interference from other wireless devices.
- App Not Detecting Device: Confirm the adapter is powered on and within range. Try refreshing the device list in the 'DX-SMART' app.
