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
non-volatile memory.
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.
