elee532 Posted May 19, 2019 Share Posted May 19, 2019 Am I correct in my recollection that the IR outputs on the EA1 are mono? I'm trying to use an HDbaseT device that has an IR input that is stereo. Is there a way to do this? Thanks! Quote Link to comment Share on other sites More sharing options...
sonic30101 Posted May 19, 2019 Share Posted May 19, 2019 It is mono, if the hdbaset is stereo it may have came with an adapter. If not you will probably have to use a stereo cable and splice the tip of the ea side to the ring of the extender kit because the extender is usually tip-5volt, ring-signal, sleeve-ground. And the mono is tip-signal and sleeve-ground Quote Link to comment Share on other sites More sharing options...
elee532 Posted May 19, 2019 Author Share Posted May 19, 2019 Thanks! So, would something like this work? https://www.amazon.com/Monoprice-107129-Stereo-Adaptor-Plated/dp/B005E2XZYC/ref=sr_1_8?keywords=3.5mm+mono+to+3.5mm+stereo+cable&qid=1558270183&s=gateway&sr=8-8 Quote Link to comment Share on other sites More sharing options...
chopedogg88 Posted May 19, 2019 Share Posted May 19, 2019 I've always used 3.5mm male-male STEREO cables to send IR from the controller to the hdbaseT, if that's what you are asking. Quote Link to comment Share on other sites More sharing options...

elee532 Posted May 19, 2019 Author Share Posted May 19, 2019 Interesting. Thanks @chopedogg88. I'm definitely confused now though. @sonic30101 says the IR outputs on the EA1 are mono. You're saying that a 3.5mm stereo cable from the EA1 to the a HDbaseT transmitter should still work though? Thanks! Quote Link to comment Share on other sites More sharing options...

sonic30101 Posted May 19, 2019 Share Posted May 19, 2019 Try the stereo cable first, but not all brands work with a straight through cable Quote Link to comment Share on other sites More sharing options...
Crustyloafer Posted May 20, 2019 Share Posted May 20, 2019 They are quite often different voltage too. Blustream who we use for almost all our HDBaseT matrices have a stereo 12V IR input jack. Very thoughtfully they come included with 4x IRCAAB cables, as list in link below, which covert the 5V mono to 12V stereo in order to work with the IR inputs on the matrix. HDAnyhwere is the sam and I have used several of the spare IRCAB cables on other take-over jobs involving HDAnywhere matrices and they work perfectly on them too. https://www.blustream.co.uk/hmxl44cskit I have quite a few of these spare, I can send one to you to try out and if it works I can arrange to order and supply more to you.

Thanks! Why wouldn't a stereo cable work for a mono connector? With mono you just need the tip and sleeve connections, not the ring. Every cable, whether mono, stereo, or stereo+mic, has a tip and sleeve. The ring, or multiple rings, on a connector should not prevent the tip and sleeve from connecting. xc420 1 Quote Link to comment Share on other sites More sharing options...
sonic30101 Posted May 20, 2019 Share Posted May 20, 2019 On some hdbaset kits the pinout is below and needs to be crossed over to be properly connected. Others are tip and sleeve and work with a regular stereo cable Tip-5volt constant to power a repeater Ring-signal Sleeve-ground On a c4 controller Tip-signal Sleeve- ground Quote Link to comment Share on other sites More sharing options...

Everything else has failed. I tried the stereo cable that @chopedogg88 recommended above. I tried a Mono to Stereo adapter plugged into the C4. I tried a Stereo to Mono adapter plugged into the HDbaseT device. Nothing worked. Thanks! Quote Link to comment Share on other sites More sharing options...

Thanks! Sure, send me a PM with your name, address contact details etc. and I'll send one across to you. I'm on holiday jut now and not back until Saturday but will send one to you then if I can' get one of my colleagues to send one sooner. elee532 1 Quote Link to comment Share on other sites More sharing options...
elee532 Posted August 10, 2019 Author Share Posted August 10, 2019 Well, I have seemingly tried everything, and I can't get IR signal to send over my HDBaseT extender. Stereo cable. Mono cable. Mono to stereo and stereo to mono adapters. 5V mono to 12V stereo cable. Am I missing something? Anything else I might try? Quote Link to comment Share on other sites More sharing options...
sonic30101 Posted August 10, 2019 Share Posted August 10, 2019 Have you taken a stereo cable from the controller into the transmitter but cut it open and spliced the wire that corresponds to the tip of the controller side to the ring of the transmitter side leaving the tip of the transmitter side capped off? Many of the extender kits I have seen have a constant 5v on the tip side of the extender which is for powering an IR repeater eye and causes issues because the signal input is on the ring terminal not the tip coming from a control system. If you dont have a way to testing continuity split the wire open. cut the red and the white (sometimes black). leave the ground connected. Splice the white of 1 side to the red of the other. cap of the unused ends to avoid a short. Plug the side with the red into the transmitter then the white to the c4 controller to cross the pins to the corresponding terminals Quote Link to comment Share on other sites More sharing options...
elee532 Posted August 10, 2019 Author Share Posted August 10, 2019 I have not tried this. I'm a little intimidated by the idea, but I'll give it a try this weekend. One thig I want to clarify... you're talking about doing this to the cable that runs from the EA1 to the HDBaseT transmitter IR input? Thanks!

Plug the side with the red into the transmitter then the white to the c4 controller to cross the pins to the corresponding terminals Hi @sonic30101. I finally got around to trying this cable splicing idea as you suggested. I took a stereo cable, spliced red on one side to white on the other, kept the yellow together, and left the other red and white capped, and plugged the red side into the transmitter and white side into the C4. Unfortunately, no luck. Any other thoughts? I guess I'm going to have to give up on the HDBaseT matrix and just bite the bullet and run another HDMI cable from the AVR to the projector. Thanks!

Crustyloafer Posted October 19, 2019 Share Posted October 19, 2019 Hi Edward, did you not have any luck with the stereo to mono cables I sent you? Quote Link to comment Share on other sites More sharing options...
swassbac Posted April 17, 2021 Share Posted April 17, 2021 I know this is an old thread but I thought I'd try and see if any of you have a suggestion. In the past, I never had any luck with a stereo 1/8" patch cable and the only way I was able to pass the IR from the C4 controller to an HDBaseT sender (using the Accell units - https://www.amazon.com/Accell-E090C-003B-UltraCat-Single-Extender/dp/B0058M3RW8/ref=cm_cr_arp_d_product_top?ie=UTF8) was to attach an emitter to the EA5 output and then attach an IR receiver to the HDBaseT sender. I tape the two together and it has worked reliably but always to be a hack. I am updating some things in my rack and thought it would be nice to clean those up but I haven't been able to figure out a way to from the C4 mono IR output to what I assume is a stereo IR input on the Accell units. I've tried a mono to stereo adapter and a binary 12V adapter that says it "removes 12VDC for IR connection to control system" with no luck. Any ideas?

RAV Posted April 19, 2021 Share Posted April 19, 2021 You might test the IR input jack with a stereo cable and a multimeter to figure out which parts are + and - voltage, then use the - and the other one for the IR input direct. Since it includes a receiver they could have done anything, and it may not even be a 12v IR system. Quote Link to comment Share on other sites More sharing options...
sonic30101 Posted April 19, 2021 Share Posted April 19, 2021 Cut the ends off at the extender and land them into this in the right pinout https://www.amazon.com/dp/B07PMRCMCT/ref=cm_sw_r_cp_apa_glt_fabc_XD84WKYQ5RA1YPFF9PN9 Quote Link to comment Share on other sites More sharing options...
