Black Box Data Buffer transceiver

Are legacy DOS systems still doing important work for you? Do they get bogged down printing page after page of data? The DataBuffer or DataBuffer Plus eliminates bottlenecks in your print jobs. It buffers data from your computer and sends it to a printer, plotter, or other output device. The DataBuffer also takes data from or sends data to other devices such as scanners and modems. Four different models of the DataBuffer (serial-to-serial, parallel-to-parallel, parallel-to-serial, and serial-to-parallel) are available in 128 KB, 256 KB, 512 KB, 1 MB, or 2 MB. All models feature a serial buffer with one input port and one output port. Each serial port can be configured individually for speed, number of data bits, parity, and flow control via rear-panel DIP switches. All models have multiple-copy capabilities, and can generate self-test messages from the output port.
