Yes, it is all quite logical getting the cable the right way round. At the source the digital electrical impulses have to be converted to photon light pulses. At the receiving end those photon light pulses have to be converted back to electrical digital pulses. So the arrows go away from the sending unit and point towards the receiving unit.\nLogic, Logic, Logic my boy!\n\nI've heard that before... yet we hoo-mans have a strange propensity for breaking logic in a manner that defies all... logik.\n:)\n(Oh, and saying the end the voltage inserter goes on doesn't matter, well that partially breaks my brain. *blushes And it would REALLY suck to blow up my new computer! :oops: )\n\nThank you, Doc!
