| D25 Parallel port pinout? |
| (1/1) |
| Jackster:
Am I right in saying that this D25 to D25 has pin 1 through 13 and 14 through 25 reversed on one end? As in pin 1 goes to pin 13, pin 5 goes to 9, pin 15 goes to 24 and pin 20 goes to pin 19? Is this a standard parallel connection? |
| helius:
No. By looking at the back of the shell you cannot see the gender of the connectors, nor the pin numbering. If one connector is male and the other female, it is a straight-through cable (1-1, 2-2, ... 25-25). |

Somebody already beat me to it, but what you're probably looking at is a plug and a socket, if you plug them together you'll see they all go straight through The standard Parallel printer port interface is DB25 Centronics (57-30360 plug) 1 1 Strobe 2-9 2-9 Data0 -> Data7 10 10 ACK 11 11 Busy 12 12 Paper Out 13 13 Select In 14 14 Autofeed 15 32 Error 16 31 Reset 17 36 Select 18-25 19-26 (Grounds) (oh dear god, I just did the pin-pin mapping off the top of my head - some useless knowledge buried in there. I double checked it, but it was right) |

Yep male and female. The photos I was sent showed 2 male ends |O |

The one with the embossings is the outer hood, this is the male part. https://buildyourcnc.com/Item/electronicsandmotors-connector-male-dsub-DB25-ribbon |
