Interconnect Devices with Different Data Rates, CE Data Formats, and Handshaking RS-232 Baud Rate Converter Model 232BRC Dated but valuable equipment with incompatible communications standards can be put back into service with this Model 232BRC Baud Rate Converter. Many older and proprietary system devices lack the option to reconfigure baud rate, data format and handshaking. Model 232BRC acts as a translator between asynchronous devices, matching each device’s needs while maintaining the highest possible throughput. Each side of Model 232BRC can be individually configured to suit the device connected to it. A PC is used to configure the Model 232BRC, but once configured, the module may be installed on any system. Non-volatile memory maintains all parameters when power is removed. 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. 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, allowing the higher speed device to be located on either port. The included PC setup software walks the user through all possible parameters. There are no dip-switches or jumpers to configure. The 232BRC has 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. A 16 Kbyte buffer on each port ensures that data flows at the highest rate supported by the slower device with no data loss. Three LEDs indicate power and the presence of data in either port’s buffer.
