Title: Ethernet Dongle Pinouts
Post by: rkauer on March 24, 2007, 04:15:56 AM

Hello. It's me. Again. The Central Scrootinizer.

No. It's me. Again.

I need a simple info: how is INTERNAL ethernet PCMCIA dongle pinouts?

I've don't find this information anywhere on the net.

I want to solder (yup) a dongle on my Sohoware ethernet PCMCIA. This have a female conector, but lack manual (only a peecee drive - useless for us).

Someone can help?

The dongle connectors are proprietary and not standardized - the manufacturer is your only source of information.

I've tried it. No good.

But after some more googling, I found it. Posted here to help other ppl with the same issue:

[color=0000ff]Mine is a SOCKET AE credit card. but having seen the xircom and others[/color]
they seem to be the same (but this is at your own risk not mine if
you decide to try)

By the way this only applies to those cards with straight dongles to an
RJ45, not to those with pods and BNC connectors.

Now the connector is 15 pins (the card has 15 small sockets)

if holding the card again the right way up and number the sockets from
RIGHT to LEFT as below

CARD 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
RJ45                 6 3 2 1
As you know there are only 2 twisted pairs in use, although the RJ45 is 8
pins.

the first pair is connected to the RJ45 plug to pins 1 and 2

pin 1 should go to pin 7 of the card and pin 2 should go to pin 8

the second pair is connected to the RJ45 plug to pins 3 and 6 (yes six not
4)

pin 3 should go to pin 9 of the card and pin 6 to pin 10 of the card

and that is it

One option is to carefully open up the pcmcia card, and look at the tranceiver chip inside.  These are normally easy to spot as they are near the connector end.

You should only need to solder 4 pins for it to work.  You should be able to get the chips datasheet if its not obvious what the pinout is.

I did this a while ago on some 3com 10 meg ethernet cards which had missing dongles and they worked great!

3COM dongles uses pins 1,2,3 and 4 instead. It's easy enough to convert.  :crazy::crazy::crazy::crazy::crazy:
