(...) Thanks John. I agree that from the electrical point of view, just connecting one port 4 to another port 4 should just work with no hardware other than the cable (for short lengths, like the cables that come with the NXT). For longer cables, a (...) (17 years ago, 5-Jan-08, to lugnet.robotics.nxt)
