An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
Old Macintosh DB-25 SCSI port (narrow) Apple used DB-25 connectors, which, having only 25 pins rather than 50, were smaller and less expensive to make, but decreased signal integrity (increasing crosstalk) [citation needed] and cannot be used with differential signaling. Furthermore, DB-25s were commonly used for RS-232 serial cables and also ...
D-subminiature connectors are used to carry balanced analog or digital audio on many multichannel professional audio equipment, where the use of XLR connectors is impractical, for example due to space constraints. The most common usage is the DB25, using TASCAM's pinout (now standardised in AES59 by the Audio Engineering Society [1]). To avoid ...
When IBM implemented the parallel interface on the IBM PC, they used the DB-25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36-pin micro ribbon connector at the other. In theory, the Centronics port could transfer data as rapidly as 75,000 characters per second.
Because personal computers first used DB-25 connectors for their serial and parallel ports, when the PC serial port began to use 9-pin connectors, they were often labeled as DB-9 instead of DE-9 connectors, due to an ignorance of the fact that B represented a shell size. It is now common to see DE-9 connectors sold as DB-9 connectors.
The search for missing hiker Susan Lane-Fournier, 61, took a tragic turn after her body was found over the weekend in Welches, Oregon, an unincorporated community at the base of Mount Hood.
A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data.
