I really canít help with debugging code, but the approach is incorrect. StimTrackerís TTL Input happens to use the same R45 physical connector that is used by Ethernet, but it uses TTL signals and not Ethernet signals.

What you need to do instead is use the TTL / digital output features of the Arduino. This implies that you need to cut one side of the RJ45 cable and somehow connect the wires to the Arduino board. But on the positive side, this should be quite a bit easier to write software for.
