This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

Way back in the day, analog/digital converters (ADCs) had simple, parallel interfaces, either TTL or high-level CMOS. Many of these converters could be clocked down to zero samples/second: once you ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

For more than 20 years, the parallel bus interface has been the mainstream storage interconnect for most storage systems. But increasing bandwidth and flexibility demands have exposed inefficiencies ...

This file type includes high resolution graphics and schematics when applicable. Practically every electronic product made today uses one or more serial data interfaces. A serial interface is the ...
