I am trying to figure out how to combine to emitters into one so I can use say a all in one remote and a whole house system and share an emitter. any one know how to go about this?

seperate emmitters stacked or right nest to each other...dont know any other way to do it.... i could figure it out but it will cost more todo it your way

ed

Use a Xantech 282 TP. Just what the doctor ordered; two plugs, one head.

Thanks thats how we do it but I just did a fourm search and found what I was looking for. Thank you any way

I'm thinking that like in the way of using an input on connecting block for each input

Using just the IR and the ground from each signal cable....
Then just running emitters to each component.....

Two IR sensors=the two leads from the house, and from the all in one/ into a connecting block and then into emitters...........


If you were thinking about splicing the two together.........you need to be diode isolated and worry about cross talk and such.........plus false signals..........

If I'm wrong its still monday, Ill get better by the middle of the week.

Ya I was thinking more along those lines. Zener diodes tied to the plus of each of my incoming wire. I want to know if this works, and how well? I am testing it my self but feed back would still be great.

Combine Emmitters

Xantech now makes an emiiter with 2 ea 1/8" ends - already diode isolated. Search their site. There also was a thread about this a few months back on this forum.

yeah, on post number 3 on this thread.

Impaqt,

I believe you have the diodes backwards in your drawing. I'm assuming the red lead of the emitter is the anode (usually connected to positive.)

The way you have it now, as the + lead rises in voltage, the voltage is blocked from going to the emitter. The emitter will never be turned on by either device.

If you reverse both diodes, the anode of both diodes connect to the positive terminals, and the cathode (banded end) connects to the anode of the emitter, the solution will work. When the top positive terminal is driven high, the top diode conducts and the emitter turns on, the bottom diode is reverse biased, so no voltage shows up at the lower + input, protecting that equipments output stage.

Also, rather than zener diodes, I would recommend schottky diodes. The zener diodes are designed to break down when a voltage above some threshold is applied, in this circuit, this behavior is not desireable. The schottky diodes have a lower forward voltage drop, and will drive the emitter more strongly.

Note: Impaqt has fixed the drawing earlier in this thread... Go by the drawing, and it should work!

Thanks guys the xantect may be the way to go I need check that out! I have already figure out how to do it with the diodes which it works but its not pretty.

Yup... Thats what happens when you dont do schematics for a long time and try to go by memory.. DOH!

Fixed....

Its almost like your invisible for some reason:)

Who said that? ;-)

I was browsing the adult entertainment DVD section today... Isn't there a movie out-- "Two Into One"...?
