Chapter 1: INTRODUCTION
The 232BRC acts as a translator between devices with incompatible asynchronous serial communications. Each port uses a dedicated UART and includes a 16 kbyte receive buffer. Each port can be independently configured for data rate, data format, and handshaking.
Each side of the 232BRC can be configured to match the connected device. It supports any data rate up to 115.2 kbps and all standard data formats. Each side can either supply or accept hardware or software handshaking. Setup parameters are configured through the PC setup software provided and saved in
The 232BRC is supplied with two DB9 connectors. The female connector is configured as a DCE for connecting to PCs, Terminals, and other DTE devices. The male connector is configured as a DTE for connecting to Modems and other DCE devices. Three LEDs indicate power and the presence of data in either port’s buffer.
Applications
•Connect devices with different data rates.
•Convert from hardware to software handshaking.
•Convert between data formats.
•Add handshaking to a streaming device.
•Use as a port buffer to increase throughput.
