Combining IR signals
« on: June 07, 2006, 10:37:31 PM »

I have two control devices that connects to two seperat ir emitters. Both emitter is for one vcr/dvd combo deck. Is there a simple way, maybe using dioes, to use one emitter on the two control devices?

Thanks

Universal remote with signal memorization

thats not going to work in this room, or i should say lab. this system is for an ultra sound lab which has a complicated a/v control system using an extron mlc 226 ip controller. the system has to be designed simple enough to operate that even someone of less intelligent can operate it.

alright ill try to re-word the question.

imagine:
device A has its own IR transmitter
device B has its own IR transmitter

the IR transmitter of device A and B goes to one VCR

i would like a way to use one IR transmitter for both device A and device B

You have universal remote controls.

Some TV's and VCR's remote controls have the option to control another device.
For example we have a Zenith TV, and we can control our JVC's VCR.

device A and device B are both computer programmable modules.

this setup is for a automated A/V system where a universal handheld remote sort of thing wont work. this is not for a typical home theater setup, as i stated before, this setup is for a Ultra Sound lab

more specificaly, device A is going to be a MLC 266 IP from Extron (part number 60-600-00) and device B is a standalone DVCM from Extron (part number 60-754-02)

so basically, you have 2 devices each with their own transmitter but you want both of them to connect to the same IR emitter.
No, there really isn't an easy way to do that without knowing how both devices handled thier transmit data.

I noticed the first device is RS232, you might be able to get something to replace the DVCM that would slave into the first controller instead.

Why is it so bad to have 2 emitters? Are they interfering with each other or something?

there isnt really anything wrong with two emitters. it just means they both need to be placed on the vcr/dvd deck right next to each other, and could potentialy block the signal from the deck's remote. (i havent tested this yet)
