4.4 Connecting to a Computer (PC)
To connect the CP26 adapter to a computer, an additional CP11 Bluetooth adapter (sold separately) is required. The CP26 adapter cannot be directly connected to a computer.
- Driver Installation: Download and install the 'CH341' driver on your computer.
- CP11 Setup: Plug the CP11 adapter into a computer USB port and power it on.
- CP26 Power On: Press and hold the KEY button on the CP26 for approximately one second to turn it on.
- Serial Port Configuration: Open your serial port software (e.g., Putty, RealTerm) and select the COM port corresponding to the CP11 adapter. Configure the default parameters to 9600bps/8/n/1.
- Connection: The CP11 adapter will automatically search for and connect to the CP26 Bluetooth converter. The blue light on the CP26 will remain on once connected.
- Data Exchange: After successful connection, data can be exchanged between the computer and the RS232 device connected to the CP26.
4.5 Device-to-Device Communication
Wireless data communication between two devices using CP26 adapters is achieved as follows:
- Connect the first CP26 adapter (configured as 'Master') to Device 1 via its RS232/RJ45 interface.
- Connect the second CP26 adapter (configured as 'Slave') to Device 2 via its RS232/RJ45 interface.
- The CP26 Master Bluetooth module will automatically pair with the CP26 Slave Bluetooth module.
- Once paired, data can be exchanged wirelessly between Device 1 and Device 2.
5. Operating Instructions
