#19687 - 03/24/08 09:46 AM Need help with IR
Hermanus Hermanus newbie Registered: 03/17/08 Posts: 4 Loc: South Africa	I am trying to learn the IR to control my AV equipment using Ocelot and SECU16 - IR. It seems to learn the cmd fine but noting happens when I try to transmit the IR. Herewith the steps I have taken to set it up. I am hoping you can pickup what I have done wrong. Setup: - Install Ocelot and connect 12VDC power supply - Install SECU16 - IR close to AV equipment also with 12VDC power supply - Connect COMA and COMB on Ocelot to COMA and COMB on SECU16 - IR using CAT5 cable - Connect triple IR emitter to IR - 0 jack on SECU16 - IR - Start CMax (V2) software. - Click on Comms \| Attach to Controller - Click on Infra - Red \| Learn Infra - Red Command - Select Ir Number 1 and Ir Frequency 38 (Not sure what Frequency must be, forums suggest using 38 - 40) - Click Learn Ir Button – Red window “Waiting for IR Learn” appears. - Goto Ocelot and point remote (Samsung Plasme) to “IR receiver” and press the power button - The red window disappears and the Cmax software shows (IR Learn Complete) - With the IR emitter suck on the Plasmas IR receiver I press the Transmit IR button and nothing happens

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	At the last step, are you using "Transmit infrared command" or "Transmit Remote infrared command"? Only the "remote" command will allow you to choose the module address of your SECU16IR and the zone number. The non-remote command can only transmit IR from the Ocelot's own IR-out port. _________________________ "If you don't know what you're doing, do it neatly..."

erics erics newbie Registered: 09/13/08 Posts: 7	I am having the same problem i.e. I seem to be able to learn an IR command however when I play it back nothing happens. One difference is that I am not using the secu16, I am using the ocelot built in IR.

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	Do you know if the IR emitter that you have is of the "visible light" type, where you would see it blink when it is emitting? If so, then you should see it blink when you use the "Transmit IR" utility in C-Max. _________________________ "If you don't know what you're doing, do it neatly..."

erics erics newbie Registered: 09/13/08 Posts: 7	Unfortunately they are not of the emitting type so I can't see if a signal is being emitted from the ocelot to the IR blaster. Your question how did lead me to another test. I tried to use the ocelot as an IR repeater so I tried to "pass through" an IR signal from the Ocelot built in IR receiver through the Ocelot IR emitter connected to an IR stick emitter and nothing happen i.e. my devices did not turn on or off. I then connected an IR receiver to the aux receiver input on the Ocelot and tried again with no success. I see the signals being received by the Ocelot as the X-10/IR red ligh goes on/flashes when I press a key on the remote. Also note that I did load a program into the Ocelot memory so I do get 4 flashes of the green active light. I am running C-Max v2.00e5 and my firmware on the Ocelot is V 8.31/58 Application V3.18

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	The Ocelot dosn't do an automatic "passthrough" of IR signals it receives. To do something like that, you would need to actually learn each IR code and have IF/THEN statements to transmit the same code number that you just received, etc. Since your emitter doesn't blink, it is hard to tell if the problem is with nothing being sent or if it is being sent but is not correct (eg: the carrier frequency could be wrong, etc). The other thing is that the stick on emitters are quite weak and they need to be stuck exactly over (and very close to) the IR receiver of the device you want to control. Even being an inch away will not work. _________________________ "If you don't know what you're doing, do it neatly..."

erics erics newbie Registered: 09/13/08 Posts: 7	I'll use an oscilloscope to check if a signal is coming through when I transmit a learnt IR signal and let you know the results. Thanks for the help.

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	Yes, that would be a good test. To be sure to see a signal voltage, put a 470 ohm or 1k resistor across the output jack as a load. If that test shows that a signal is being sent, then connect your emitter and test the output again but from inside the Ocelot (unless you can somehow access the tip connector externally with the emitter plugged in). Test again for a signal voltage when transmitting, showing that the emitter is working and putting a load across the IR output. _________________________ "If you don't know what you're doing, do it neatly..."

erics erics newbie Registered: 09/13/08 Posts: 7	I hooked up my oscilloscope and it appears that while the X-10/IR led lights up there is no signal being sent to the IR emitter output on the Ocelot. I also tested the using the Debug Timers and Variables and variable 60 does get set to the appropriate code when I press a key on my remote i.e. if I learn "power on" from my remote in ir memory location 1 and "power off" in ir memory location 2, when I press "power off" a 2 appears in variable location 60 and when I press "power on" a 1 appears in variable location 60. As far as I understand this means that the Ocelot is learning correctly. Does this mean I should return the Ocelot or are there other tests I can perform?

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	One thing you could try is to verify that the IR/X10 PIC chip is well plugged into it's socket. This is the long, narrow chip near the center of the board with a label on it. With the Ocelot powered off, try removing the chip, check that all pins are straight, and then plug it back in carefully. _________________________ "If you don't know what you're doing, do it neatly..."

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	ADI has had many people try things like that in the past and have never reneged on the warranty. They will even sometimes ship out a replacement chip for a customer to swap out himself. I also figured that if you had an osilloscope and knew how to use it, plugging in a chip would be a pretty straightforward thing for you. _________________________ "If you don't know what you're doing, do it neatly..."

erics erics newbie Registered: 09/13/08 Posts: 7	Well the pep talk worked $\:D$ I opened the ocelot and thought there wasn't any pins that were bent, after reseating the chips it seems that everything now works as it should. Thanks for the help.

erics erics newbie Registered: 09/13/08 Posts: 7	Well not so good now, the unit doesn't transmit signals again I am pretty sure it is defective now. Maybe it is some bad contact I am not sure.

UVerseJerry UVerseJerry newbie Registered: 11/24/08 Posts: 5	I have a motorola UVerse VIP 1216. The ocelot continuously fails to learn the codes. Using the IR_Max program I am able to see that the remote sends out 3 identical pulse patterns, carrier freq is 36Khz. Problem is the Ocelot Learn does not receive 3 identical pulse patterns. Hence, it fails to accurately reproduce the IR command. Sometimes it says it's received the signal but after I download it to view it, I get only one pulse. This learn is extremely flaky. BTW, I tried another remote from a sylvania TV and it replicates it perfectly. I'm assuming the ocelot is not receiving the signal without noise. Hence, I get garbage. I wonder if there is a way to hardwire the led from the remote to the ocelot to remove the noise? I'm at my witts end. About ready to return all 2K worth of equipment and move on to another solution for my larger project. Tech support has been little help.

Guy Lavoie Guy Lavoie Beyond All Hope Registered: 12/21/02 Posts: 6406 Loc: Montreal, QC, Canada	I just looked at the threads at Remotecentral and it looks like people are having trouble with the UVerse IR codes: http://www.remotecentral.com/cgi-bin/mboard/rc-prontong/thread.cgi?8237 You might want to try some of the suggested fixes discussed int he thread by using IR-Max. _________________________ "If you don't know what you're doing, do it neatly..."

UVerseJerry UVerseJerry newbie Registered: 11/24/08 Posts: 5	Thanks for the advise. Tried it, there was one individual that had posted pronto codes for the u-verse stb. Converted those to Lir and retried. Another failure. I'm beginning to think that maybe the ocelot is way off frequency or has some other issue. So far I know of two units that replicate the IR codes without error, Slingbox and Pronto. Maybe Tech support can discover why the ocelot has such an issue?? Kevin in tech support is investigating. Any other ideas would be appreciated. Thanks again.

UVerseJerry UVerseJerry newbie Registered: 11/24/08 Posts: 5	An update, Scoped a learned code vs. a remote (across the LED) reading. Patterns were almost replicated. However, the learned code was about .6 ms longer that the Remote code. (11.6 vs. 12.2) I'm thinking this has to be the issue. Your thoughts? And how do I get the ocelot to replicate the pattern??
