Model: 232BRC

Baud Rate Converter

Features

 Data Rates up to 115.2 kbps
 16 Kb Buffer Prevents Data Loss
 Hardware and Software Flow Control
 Interconnects Devices with Different Data Rates, Formats, and Handshaking

Functional Description

Put legacy equipment with incompatible communications standards back into service. Many older or
proprietary system devices lack the option to reconfigure baud rate, data format, and handshaking. The
232BRC acts as a translator between asynchronous devices, matching each device’s needs while
maintaining the highest possible throughput. Each side can be individually configured to suit the device
connected to it. It supports data rates up to 115.2 kbps and all standard data formats. Each side can either
supply or accept hardware or software handshaking. The included PC setup software walks the user
through all possible options. Once configured by a PC, the module may be installed on any system. Non­volatile memory maintains the parameters when power is removed. A detailed instruction manual is
contained on the CD ROM which ships with the product. A 12VDC power supply is required (not included).

Operation

Refer to the Instruction Manual contained on the CD ROM.
The 232BRC has twoDB9 connectors. The female connector is configured as DCE for connecting

to PCs, terminals, and other DTE devices. The male connector is configured as DTE for connecting
to modems, and other DCE devices. Refer to Table One and Table Two for DB9 pin-outs.

Three LED’s indicate power and the presence of data in either port’s buffer.
