Humax HFA100 OFA receiver

tricky · Post by **tricky** » Wed Sep 14, 2005 5:41 pm

My JP1 cable is in the mail and soon the learning process will begin:
I have a OFA9960 and have managed to get some of my other remotes partially onto it but one I had to use the IR LRN function as I cant find a code for it, it is an OTA receiver remote HUMAX HFA100 the remote for it is HUMAX RT-761
Using the "PVR" device and using the IR LRN function I got most of the main functions onto the OFA but one thing seems odd, I can't program the HUMAX power key to the OFA Power key but I can program it to another one such as the "exit" button. In the OFA manual it doesnt list the power key as not being programable.
Maybe I shall figure it out as I get through the learning process.

There are a few JP1 remotes that don't allow learning to the power button. Off the top of my head I don't know specifically about the 9960, but your description leads me to believe that's the case.

Once you get the cable, you'll be able to load an upgrade for the Humax with the right code on the power button.

I've looked (nearly?) everywhere for the upgrade to the humax hfa100 you mentioned. In the files section here and also on the yahoo jp1 group file sections.

Maybe I am just overlooking it somehow. I did run across other humax products, so maybe I will try them and see if they are close enough.

I'm well pleased with my modified 6131 and have got it working fine with all of my other devices.

And I don't mind "learning" from my hfa100's remote but since you mentioned an upgrade was already available I thought I would ask before I re-invent the wheel.

thanks!

Historically, similar components from the same manufacturer normally use the same remote control codes. Nobody suggested that your exact model had an upgrade here, but if you look at the four Humax upgrades in the file section, you will see that three of them use the same protocol/device/subdevice combination (NEC1:0.16) and within those three, the EFCs/OBCs for the various functions are the same - so it's a pretty good bet that Humax is consistent in this regard and you can use any one of those as a starting point. If all of the functions you want are not there, then you can do a code search (test unused OBCs) to fill in the gaps after achieving basic functionality.

The fourth Humax upgrade uses NEC1:0.48, but it is a Sat/PVR box, so that may be why they chose a different subdevice number - BUT the EFCs and OBCs are still the same, so it's clear Humax tries to retain consistency across their line.

I don't believe I did say an upgrade was already available. The OP in this thread stated that he was using learning to capture the signals but he couldn't get learning to work on the POWER button, so we suggested that once his cable arrived he would be able to load an upgrade which would have the correct code programmed to the POWER button, the implication being that he would use his URC-9960, which is a learning remote, to capture all the signal info then build a new upgrade himself.

If the URC-6131 is your only JP1 remote, you don't have the ability to learn the signals yourself, so your only options are to either try one of the other Humax upgrades to see if they are close enough or to wait for "tricky" to load up his upgrade.

Did you ever create an upgrade for your HFA100? If so, could you load it
into the file section please as we have a user that needs it.

Hi Rob
Do you believe I am still waiting for my cable to arrive from Hovis, I guess there is a problem somewhere. So unfortunately not. Will upload when I finally conquer the problem .......

oops, my mistake. I mis-read your post as saying "you may download an upgrade from the files area". Clearly in hindsight that is not what you wrote, but rather what I was hoping that you wrote. I'll try and be more careful next time. Glad this is the "beginners" forum.

I loaned out my other JP1 remote (that I previously used for "learning") to a friend. His family was so satisfied with the upgrade we put into the remote for their set top box, and all of their other gadgets, that he just reimbursed me for the remote. I haven't yet replaced it. I probably should. But I also am intrigued by Tommy's interface for digitrace and the Java code that some others in the group are working on, that I may build that before I replace my learning jp1 remote.

I will also study and experiment with the other Humax upgrades that are in the files area. Perhaps I will get lucky.

Thanks for your helpful suggestions.

BV,
all of the Humax upgrades in the file section use either NEC1 device 0.16 or NEC1 device 0.48 (and many of the OBCs are common between them), so give at least one 0.16 file a try then if that doesn't work, give a 0.48 file a try.

And when I say "work", for the first step just focus on if "some" buttons work, particularly the numeric buttons. Once we find a file that works some buttons, we can narrow down the search.

If neither of those device codes work, try changing the sub-device code from 16 or 48 to 17 or 23. I suggest that just because I've received some other Humax upgrades from UEI that use those codes, and again, the OBCs were very similar across the codes.

Tricky,
While you wait for your cable to arrive, you could try loading an upgrade through the Kameleon's modem. Just a thought.

Greetings,

Good news-- I built Tommy's IR interface, and using Hal's new Java app, I was able to see that you were right, RobMan-- it is NEC1 0.48. So, I started with the humaxv1.txt upgrade, and used RM to create an upgrade for the hfa100, for my (extended) 6131.

I need to do a lot more testing, and finish decoding all of the buttons, but at least I can change the channel now.

Thanks for all of the help. I'll put a quick note over in the hardware section to report on that also.

William

ps: I'm gonna have to study up on the procedure to upload this upgrade to the group, once it is tested and completed.

Thee's nothing to study, just click on the

File Section link at the top of every page, click on the relevant folder (probably HDTV or SAT), then click the

button.

Finally manged to aquire a JP! cable from DIY Gadget, then started to swear and sweat but finally things started to click.
I used the Humax HFA-100 file that bvwelch posted, changed a few things to make it more comfortable with my OFA URC 9960 and got the power button to work.

Thanks bvwelch and for robman and others for a fine site, a little confusing at first.
