Guest guest Posted December 30, 2006 Share Posted December 30, 2006 Can I use a wireless connection on certain controllers that are daisy chained to other controllers? IE: wireless to my neighbors house and then the rest of his are connected via cat5.Since I have your attention I'll ask a related question. Do I have to daisy chain controllers together or can I connect them using a network hub?Brian Link to comment Share on other sites More sharing options...

Guest guest Posted December 31, 2006 Share Posted December 31, 2006 No. Daisy chain only.What if you used an 8 conductor cat5 splitter? Link to comment Share on other sites More sharing options...

Splitting causes reflections that mess up the transmission. We would have to provide a powered splitter that would isolate the legs to allow branching without problems.

Guest guest Posted January 1, 2007 Share Posted January 1, 2007 Don't assume that this is TCP/IP or Ethernet just because it uses CAT5 cable. The RS485 protocol really just uses lines 4 and 5 in the cable (white/blue and blue) because the wire pair twisting in CAT5 gives good noise rejection. So, no network hubs.

Guest guest Posted January 1, 2007 Share Posted January 1, 2007 Thanks for the replys. I just didnt know if the RS485 protocol would be messed up with a hard wired splitter. It sure would be interesting if one day the LOR units could work with TCP/IP. But the biggest problem I can see with that would be the cable length (300') restriction on TCP/IP.Happy New Year everybody. Link to comment Share on other sites More sharing options...
