- IBM Parallel Interface: The Centronics standard has gained wide
- acceptance in the printer marketplace. It has 36 pins in the interface
- and supports distances of approximately 15 feet.
-
- With the introduction of the IBM PC, a new interface appeared, the IBM
- Parallel interface. This is a Centronics interface crammed into only
- 25 pins. Some of the leads of the Centronics interface are dropped, yet
- this interface provides for equivalent functionality.
-
- The key is that at the computer-end of the cable, a DB25 interface is used.
- The IBM PC/XT port is a female DB25 connector, meaning that the cable end
- will always be male. When you see more than a single DB25 port on the back
- of a PC, the gender of the port tells you which is the parallel port.
- The female port is the parallel interface, while the male port is a serial
- interface(ACA equivalent). This can save you time if you know this
- difference.
-
- The DB25 to Centronics cable is used to connect a printer with an
- amphenol Centronics port to a PC with a DB25 parallel connector. Don't
- make the assumption that a parallel printer can be connected to a serial
- port. Instead, note that the connector size is merely the same, the
- DB25 type.
