Any ideas?

    some context would help - what is the device in question? – Journeyman Geek Dec 9 '11 at 9:44

    Obvously, the "I/F" stands for "Inter Face". (Yeah, would help to know the brand and age of the device... and what kind of device it is, if not a laptop.) – Daniel R Hicks Dec 9 '11 at 13:02
  • It is impossible to tell what this port is if you don't tell us what device this port is on. Is this on a laptop? A keyboard? A modem? If you don't even know what sort of device this is, try editing your post to add a picture of the whole device. Then we can stop guessing and try to come up with a reasonable hypothesis for what this port is for. I've seen this connector used for everything from power connectors, to serial ports to s-video, so we really are taking shots in the dark. – Mark Booth Dec 9 '11 at 14:29

Well, its seems to be a standard 8 pin mini din port, apparently - if its a sun or apple device, it might be a serial port - it looks identical to the passthrough port on my sun model 5c keyboard .

If it had 7 pins, i'd guess it was a firewire port, since that looks like an old macbook, but the shape is wrong.

  • Used for mice and keyboards. – soandos Dec 9 '11 at 9:49
  • Well, i can't tell. All i can say for certain is, its some sort of mini din port, and its not a sun box, so it can't be a sun serial port. I'm not even sure if its a computer - too fat for a laptop, and no obvious markings to tell what it is. Its almost like one of bunny huang's ware of the week! – Journeyman Geek Dec 9 '11 at 9:53
  • Just saying that that is what I have seen them used for. – soandos Dec 9 '11 at 10:10
  • That was my first thoughts. Sure looks like the old Mac "serial" ports. – surfasb Dec 9 '11 at 11:55
  • ya. what that connector itself is certain. I really cannot say without seeing the device. I'm trying to remember if i've seen it used for midi on professional devices. I also think some maudio internal sound cards use it as a breakout box, but this isn't one and... – Journeyman Geek Dec 9 '11 at 13:27

Been searching around, and from I've gathered, it appears to be some sort of ethernet port. Though it is nowhere mentioned explicitly

Sources: gigabit ethernet port, P113S LF A 10/100 Base-TX / 100 Base-FX Converter and some PDF

But then in another source, it is a general term for input devices (Link PDF)

  • hm. I have seen one of the latter before - fiber optic ethernet would not use pins. – Journeyman Geek Dec 9 '11 at 13:18

A lot of video cards have a port like this that is for attaching a Composite/Component breakout box dongle. This is a picture of one of the connector, but I have one at home on a 9800 GTX+ that has a different pin layout. This image is from 2004, so the pin layout has probably changed since then.

  • Thats one of the things wikipedia mentioned. darned non standard ports >< – Journeyman Geek Dec 9 '11 at 13:19
