I need to use one mouse emitter for two ports on an MFR-300. The ports will be routed, and will only blast a signal during macros. These macros will only allow one port to fire at a time

so say ports one and two are used in a macro. The macro string would be port one blast, wait .5 sec, blast port 2, wait .5 seconds, blast port one.......etc. etc.

I imagine that simply wiring the ports in parallel would be fine. At least I don't think anything would blow up???? Is there some reisiter, diode, or other magical device sold by Radio Shack that might work?

You should see me play with house current (yuck yuck)

Why would you need two ports to control one piece of gear? If you send voltage out of one port in parallel with another then you're technically sending voltage INTO the output of the other port. Also the current will take the path of least resistance, so the output of your mouse emitter may be diminished or non-existant (we observed this when using one flasher from a Crestron processor as well as from an MX-250). With the MRF-300 i dont know if this would be the case, but if you can redesign so as to not need two ports i'd do that for reliability sake.

I must say - this is a very bizarre concept. Why would you need 2 ports for 1 device???

Why not just use two mouse emitters - one from each port. Then just stick them both to the front of the machine.

Or when you create devices in the MX Editor, just create another device with the codes you need and assign that to the second blaster.

JUST USE A DUAL EMITTER ON ONE PORT. OR WIRE TWO EMITTERS IN SERIES.
LET US KNOW WHAT YOU DO AND HOW IT TURNS OUT.

LATER

If you must do it this way, use this method.

xantach ir block, use a plug to plug STEREO jack from one port to the rcvr in jack, and cut the lead that has 12v.

take an mrf-300 emitter to plug into the other output, cut the mouse off, strip the wires, and hook up to grnd, and ir of the phoenix connector of the xantech connincting block. plug an emitter into the connecting block output, put it on your device.

This just doesn't make any sense. How about a few more details?

Speakercraft makes a cable that you could use:

What he's implying is taking the xantech ir block and feeding one output from the mrf-300 into the 1/8 jack input as one Ir sensor input and taking another mouse emitter or just an old 1/8 jack with a lead of wire (probably cut from an old emitter or from a 1/8 jack to 1/8 jack connector) and feeding from another output of the mrf-300 into the other ir receiver on the xantech....thus feeding both outputs of the mrf-300 into one receiver to keep the voltage seperated ....

This way requires an extra piece of equipment and yet keeps talkback from leaving one port on the mrf 300 to the other port....

Its like a two way splitter/combiner to merge the two ports.

Good luck

Chicagoinstaller, I think Ted was questioning the original poster's intent, and not questioning the solution that tippie-tie proposed.

Of course, I still think the solution I supplied would be the cheapest/easiest :-)

I wish I could elaborate more on the use but it is an "intellectual property" thing within my corporation so I can not divulge the actual use....The speakercraft item is the perfect solution....I just need to know what kind of diodeing is inside. As it is only one part that will be incorporated in an overall system.

Xantech 283TP emitter

Just found it in the manual for the BXaudio4X4 system

single emitter, two plugs

Great for having two systems and one source....

No idea about price yet

Elan Makes one as well the IR2041 dual tip/single emitter

it runs about $14-$15 or less

Hmm. Xantech and Elan are owned by the same parent.

you also could put some diodes in line
