2. IEEE 1284 - Wikipedia

   en.wikipedia.org/wiki/IEEE_1284

   An IEEE 1284 36-pin male micro ribbon printer cable connection. The computer side normally uses a DB-25 port instead of this connector. IEEE 1284, also known as the Centronics port, is a standard that defines bi-directional parallel communications between computers and other devices.

   Furthermore, DB-25s were commonly used for RS-232 serial cables and also to connect parallel printers, meaning that users might accidentally try to use completely inappropriate cables, since the printer and serial cables would fit the connector properly and be hard to visually distinguish.

4. Micro ribbon connector - Wikipedia

   en.wikipedia.org/wiki/Micro_ribbon_connector

   14-pin connector: printer port used on MSX home computers and on various other Japanese computers such as the NEC PC-6000, PC-8800 and PC-9800 series [2] 20-pin connector: VESA Digital Flat Panel digital video interface; 24-pin connector: IEEE 488 (GPIB, HP-IB) interface [3] 36-pin connector: IEEE 1284 parallel interface

5. Parallel port - Wikipedia

   en.wikipedia.org/wiki/Parallel_port

   Logical parallel port 3: I/O port 0x278, IRQ 5 (dedicated IO cards or using a controller built into the mainboard) If no printer port is present at 0x3BC, the second port in the row (0x378) becomes logical parallel port 1 and 0x278 becomes logical parallel port 2 for the BIOS. Sometimes, printer ports are jumpered to share an interrupt despite ...

   Additionally, USB ports are color-coded according to the specification and data transfer speed, e.g. USB 1.x and 2.x ports are usually white or black, and USB 3.0 ones are blue. SuperSpeed+ connectors are teal in color. [2] FireWire ports used with video equipment (among other devices) can be either 4-pin or 6-pin. The two extra conductors in ...

7. Parallel SCSI - Wikipedia

   en.wikipedia.org/wiki/Parallel_SCSI

   SCSI-1 features an 8-bit parallel bus (with parity), running asynchronously at 3.5 MB/s, or 5 MB/s in synchronous mode, and a maximum bus cable length of 6 metres (20 ft), significantly longer than the 18 inches (0.46 m) limit of the ATA interface also popular at the time.

8. EIA-530 - Wikipedia

   en.wikipedia.org/wiki/EIA-530

   Currently known as TIA-530-A, but often called EIA-530, or RS-530, is a balanced serial interface standard that generally uses a 25-pin connector, originally created by the Telecommunications Industry Association. Finalized in 1987 (revision A finalized in 1992 [1]), the specification defines the cable between the DTE and DCE devices.

9. D-subminiature - Wikipedia

   en.wikipedia.org/wiki/D-subminiature

   For example, DB-25 denotes a D-sub with a 25-position shell size and a 25-position contact configuration. The contacts in each row of these connectors are spaced 326/3000 of an inch apart, or approximately 0.1087 inches (2.76 mm), and the rows are spaced 0.112 inches (2.84 mm) apart; the pins in the two rows are offset by half the distance ...
