infared signaling

[JesperMP]

What if someone standing in the path where the IR has to "look" ?
Must be as least as inconvenient as a cable getting in the way.

I would consider some kind of radio transmitter/reciever, even though it opens up for other issues and expenses.
I can't locate the not-so-expensive Banner radio transmitters that Terry mentioned.

Oooops... I had "Banner-on-the-Brain"...(maybe the "B" in "Brain" should be lower-case...), lot's of sensor-work goin' on at work.

The Digital/Analog Transmitter/Receiver sets that I was thinking of are from Pheonix Contacts. Go to Pheonix and search for "RAD".

And JesperMP,

You are absolutely correct about the problems associated with "line-of-site" communications. All it takes is for the TX/Rx to be misaligned by just enough or for the plant manager to bring a party of Basketball players through on a tour.

Also,... While I did incorrectly reference Banner, I did not say the price was "not-so-expensive". I said, "...the price ain't that bad."

As I recall, (and I don't put much stock in my "recall") the price was in the $1200 to $1500 range.

Relatively speaking, that is, in terms of "Return on Investment", $1200 to $1500 does fall into the catagory of "not-so-expensive".

(353), oops, I mean (355) Hi, Eric.

353 is the smallest number whose 4^th power can be written as the sum of 4 4^th powers.
Oops, I mean 355 is the number of labeled topologies with 4 elements.
I think I'll head over to the AD forum and ask Tuffy 'bout this...

Hey, if nothing else, I'm learning interesting facts about certain numbers!...

GOOD FOR YOU, ERIC!

BTW, There is a rationale.

Also, BTW, if you really think you have it, PM me instead of posting it.

We wouldn't want to discourage those other possible thinkers out there.

Hats off to you for the pursuit!

I be the Fox, you be the Beagle. Catch me if you can!

We use wi-fi here at work to communicate between a Logix 5k and a CEC BattleBot (AGV).

Works most of the time unless you count the crashes...

Post back if you want part numbers.
