Help extending projector remote range

post #1 of 18
Thread Starter 
Hello -

I need help/suggestions for extending the range of the factory remote for our Sony projector. Obstructions are not the issue - just range. The projector is mounted from the ceiling, roughly 15-20 feet high, and we'd like to be able to use the remote from the sound booth at the rear of the building, about 80 feet away or so.

We had looked at one RF extender, but it requires replacing a AA/AAA battery, and our remote takes a lithium-ion battery, similar to a watch battery, so that won't work. Any help would be appreciated. Thanks!

I think you may need to use an AV Splitter over CAT5E with IR extender. Let me know if you need further help as i m quite into this repeater thingy recently

Thanks for the help... but I'm pretty new to this, so pardon my ignorance on the subject. Are you saying I need to run CAT5 cable from the projector back to the sound booth? And if so, how would that help with the remote?
Thanks again for your time and assistance!

I'm not quite sure what PhilipLimos has in mind, but you could consider a regular IR extender, such as one of these two:

PowerMid: http://www.amazon.com/X10-Powermid-PM5900-Control-Extender/dp/B00023KG40

or

The equivalent from MonoPrice: http://www.monoprice.com/products/product.asp?c_id=109&cp_id=10110&cs_id=1011009&p_id=9194&seq=1&format=2 [Doesn't get quite the same level of positive feedback that the PowerMid does]

Another thought, depending on the environment (and your budget), is to use a wifi-based setup: Something like an iTouch/iPad or Android device running an app such as iRule or Roomie, into a network with wireless capability and then use a Global Cache' iTach Flex at the projector to pick up the wifi and convert it into IR (or maybe serial if your projector can handle it). Even if there is no existing network, a cheap wireless hub would be all you need to communicate between the sound booth control device and the projector's iTach Flex. A nice feature of this approach is that it can be expanded to encompass other items such as lighting, drapes, input switching, etc.

Anyway, a few more options to consider.

The extender which i know is something which enable you to remote control ( from your bedroom ) to your system ( Living room ) 100m apart..
I m quite bad at explaining perhaps you can look at this http://www.ir-extender.net/product_details.php?product_id=41

Hi DGF, i saw the link which you suggested on monoprice. Would it be able to transmit through wall since Biggdbo needs to control it at the rear of the building? Please share your experience. Thank you!

This X10 extender, must we connect the HDMI/ AV cable from AV Device ( Player in living room ) to Display (TV in the room ) before we can use the remote so that we can watch & remote control the programme from the room?

Not quite sure what you're asking here - I'm assuming that all the necessary connections between sources and the projector are already in place, we just need to extend the range of the projector's IR remote.

Both devices (PowerMid & MonoPrice) work on a similar concept: you point the projector's original IR remote at the base station and it converts anything that it 'sees' into an RF signal that is then transmitted to the receiving unit located next to the projector - the receiving unit takes the RF signal, converts it back to IR and blasts it towards to the target device. There is actually no physical connection between either of the two extender units and the equipment being controlled (I.e. no additional cables are required between the sound booth and projector). Being RF, the transmission has some ability to pass through walls, glass, etc.

The PowerMid receiver has an integrated IR blaster, but the MonoPrice unit uses three individual emitters.

The system you linked to does look solid, but it needs a CAT5e or CAT6 cable to be run between the sound booth and the projector - I'm totally guessing, but I suspect that this might not be possible in the OP's environment.

Not sure if that helps at all...

Hi DGF, do you happen to know where can i get the detail product specs sheet for X10 extender? i can't seem to google it. Thanks a lot!

Hi, do you mean the AV is transmitted through RF - IR without any cable connection?

I think you've lost the plot on this one - the OP only wants to extend the range of his remote, not to do any long distance AV connection: that's what I was responding to. The solution you proposed did IR + AV, which wasn't what was being asked for.

Re. the "X10 extender" - just Google PowerMid and you'll get all the publicly available documentation.

Hi! First off, thanks to both of you for your efforts to help.

DGF - that X10 Powermid looks like it would work. Do you have any experience with it? My one concern is that our projector is mounted from the ceiling - about 20 feet up. So I'm not sure if we'd have to somehow mount the emitter directly to the projector, or to the ceiling just in front of it, or what. But from the description, it sounds like what I am looking for.

Thanks again, both of you, for all of your help! From someone with little experience with these kinds of things, it's greatly appreciated.

Just looked a little closer - it looks like I may have to actually mount one of those pyramids to the ceiling in order to get the signal to the projector. I'll have to check into the feasibility of that - unless someone thinks I'm looking at things wrong?

Thanks again.

I used to have a PowerMid and it performed very well. The IR transmitter module includes a reasonably powerful IR blaster, but I never measured the effective range to see how far away I could use it from the target device.

I didn't quite understand the thought progression in your last two posts - in post #12 you seemed fine with the idea of ceiling mounting the PowerMid and then in #13 you seemed aghast at the prospect! Is your concern that you'll have to go 20' up a ladder or is it some other issue? I assume that on occasion someone must physically access the projector - bulb changes, cleaning, adjusting, etc. - and I also assumed that you have access to power up there too. You'd need to find a way of ceiling mounting the PowerMid (i.e. inverted), but that could be easily achieved by creating a plinth that is larger than the plan-view dimensions of the PowerMid, mating the two together and then fastening it to something near to the projector (most projectors have IR sensors on the front and rear, so I'd look for a location behind the unit to avoid any encroachment into the path of the projected image) - the whole install could be done very cleanly (and the gloss black pyramid-shaped PowerMid is actually quite cool looking.....as long as you can't see the X10 logo biggrin.gif) - you just need a head for heights!

Yeah, I realized I kinda bounced back-and-forth. When I initially looked at the photos on Amazon, I saw a small sensor at the end of a cable, and I was thinking that sensor was all that I'd have to have near the projector. After looking closer, I realized the pyramid would need to be up there, too. Probably not a deal-breaker, just means a little more work. I plan to run it by the boss this afternoon. From everything I've looked into, this seems to be the best way to go.

So... this also means we have one of these for sale (open but unused) if you know anyone interested!

Thanks again!

The PowerMid doesn't actually use the small emitter 'bud' - the actual IR blaster is housed inside of the unit, making it completely self-contained. However, I believe you can add an extender, so this might give you a few more placement options: If the you have a false ceiling or exposed beam you could locate the receiving module out of sight and run an additional emitter, with its thin cable, from there to somewhere in the vicinity of the projector. Electrically, the 2-wire connection to a remote emitter is very simple and allows you to extend the connection significantly (100'+), so if there is an outlet that's more convenient to use (but obviously closer than your sound booth), you could locate the receiver there and 'extend the extension'.

Sorry, don't mean to labor this: I just checked out the Elkhorn Valley url you posted (very nice facility!) and am guessing that we've been discussing the setup in the Messenger Chapel? Just a thought, but as the cable for an emitter is so diminutive (normally >=18-20 awg) you might want to position the PowerMid against one of the walls and route an extension cable with an emitter up the vertical support and along the beam. Similarly, and to take us back where we started, you could even discretely run a cable from the sound booth, if you have a contiguous surface to the projector - as mentioned, the IR signal is not complicated and it can happily be routed quite large distances using a 2-wire cable. Options, options.....smile.gif

Thanks for the compliment, and you are correct about the chapel. We went ahead and ordered the PowerMid, and what I'm leaning toward at this point is just mounting the receiver to the ceiling, in front of the projector. We have a few outlets up there. The transmitter can just set on the table in the sound booth (which is actually an open balcony), next to the mixer and other equipment. I'm hoping that this relatively simple setup will work for us.

We bought a great new projector (Sony VPLEW245) before summer camp season started, but haven't been able to use it so far because its remote only works if you are basically standing directly under it. So we've been using the old projector, which is serviceable, but not nearly as bright and crisp as the new one.

Thanks again for your help!
