4. Installation Procedures
1) Connection
There is no need to install additional programs in your computer or communication devices to use the WCS-232.
Connect the WCS-232 to a serial port at your computer or communication device and supply it with power. Then
you can easily access it as if you were using the existing serial port.
WCS-232 can be powered by the following methods: DC power supply, PC USB port through USB cable or DB9
pin connector (available only if special serial ports are used).
A Bluetooth connection between two devices using the WCS-232 is automatically established when both WCS-
232 are powered on. After that, LINK LED turns red and you are free to use the WCS-232
2) Environment Setting
Since WCS-232s are connected onto the serial port of your PC or communication device, you should specify the
serial port environment information (Baud rate, data bits, parity bit, stop bit, flow control, etc.) and the RF
connection (device name, operating mode, target address, etc.) for mutual communication.
RF connection setting is required only if you communicate with other manufacturer’s Bluetooth devices instead of
the WCS-232 or change the initial setting.
For environment setting, please use “Hyper terminal” included in your Windows’ operating system.
5. Operating Environment Setting
