Very nice. Would you like your findings put on the website?

The basic idea is that you star wire the cat5e from sensors to block and tie a pair together where it attaches to the signal line of the sensor. Then I create the bus by cross connecting ins and out of the signal pairs on the blocks. It trades more wire length compared to a daisy chain for easier reconfiguration and testing. My first test was 9 lengths of 40', which comes out to a bus length of about 720' (out and back on each.) All the sensors worked perfectly. In a couple weeks, I'll get a test that tries to run to the 400m that the interface lists as the max and see how that works. In production, what I plan to do is put some extra blocks in areas where I have a cluster of sensors, just to keep the length down when it's easy. It's kind of like an intermediate distribution frame in the telephone lingo. The other nice thing is that if I ever run up against the wall of what a single bus can do, I can put a hub at the blocks and cut them into pieces with no pain. So I think it's safe to add this as a wiring option for people in the future. jerry Jerry Scharf laguna way consulting ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
