About UART

A Universal Asynchronous Receiver/Transmitter (UART) is the fundamental hardware for serial communication, controlling the speed and method of data transfer of the serial port.

Applications utilizing a network serial port between an RS-232 interface and a wireless device use a TCP/IP socket connection. Any program that uses standard TCP/IP network sockets may be used to communicate with the serial port of the Bridge. Once a socket is established to the Bridge, any data written to the socket is sent out the serial port of the Bridge. At the same time, any data received by the serial port of the Bridge is returned via the socket connection.

The Bridge network serial port may be used in two modes:

■Server Mode — TCP Listen Port

■Client Mode — TCP Connect Port

In Server Mode, the Bridge waits for a TCP/IP socket connection to be made by the network program with which it will communicate.

Server Mode should be used if you have a central server that expects to open a TCP/IP socket connection to the Bridge.

In Client Mode, the Bridge establishes a socket connection to the

IP address and port number specified in the configuration. Client Mode should be used if your system expects the Bridge to open a TCP/IP socket connection to a central server.

Configuring Operation Mode

Attach your computer to the serial port on the Bridge, and then configure the Bridge through the computer.

■Select Enable to establish a TCP/IP socket with a remote computer in either infrastructure or ad-hoc mode. This allows you to do data communication with the remote computer.

■Select Disable to disable the Network Serial Port.
