Two serials and IR over one CAT5?

Postby Wysocki » Wed Jan 17, 2007 5:43 pm

I need to run cable about 30 feet from my htpc to another room to control a Jandy serial controller, an AB8SS speaker switch, and one IR emitter. Can this be done with just one run of CAT5 cable? I think each serial takes three wires and the emitter takes two (= 8 ). There is a TINY hole that I have room to run the cables through and one CAT5 would make things easier. Would there be any problems with crosstalk (I thought that the twisted pairs prevented that).

I think it should be possible. I have been thinking about something simliar for a while but haven't done anything yet.

Sorry, thought I'd searched well enough, but you're in the same boat! :oops:

I'm guessing that the signal strength and sensitivity won't cause interference although I'll probably use one pair for each tx/rx, another for the two grounds, and another for the IR. I'll post back with the results. All I have to do now is research which pins I need for the serials.

Do any of these devices require hardware handshaking? If so, then you probably do not have enough wires.

The technical specs link at http://www.hacs.com/ab8ss.html shows the speaker switch needs just pin 2,3,5 connected. The Jandy serial adapter manual shows a full 9-pin connection but then goes on to say "The simplest functional connection between an external EIA-232 device and the RS
Serial Adapter requires connection of only DB-9 pins 2, 3 and 5.".

Looks like I am golden!
Thanks for the caution though, Krumpy!
