My company needs to mount a Cobra II board inside a metal enclosure. The metal walls are too thick to cut a square hole for the RJ45 socket. We have to use a round RJ45 socket mounted through the metal wall, and two LEDs mounted through the wall to show the Ethernet power and activity. These parts have wires connected. Can GHI supply us a solution so that the round RJ45 and two LEDs mounted on the wall can connect to the Cobra II or a ENC28 module?
If GHI cant help it would be fairly trivial to modify/create a ENC yourself to do what you need.
There are connectors like this, maybe this is a solution for your problem.
