A week ago I purchased and built a Velleman IR Electronic Volume Control to use for volume control for my audio system, since I am using active monitors.

As it turns out you must have a Velleman remote control to operate it. Since I own 27 different remotes, including a few universals, a few which can learn codes, etc., I do NOT want to buy another remote solely to control this component.

So can anyone out there help me find the VOL+ and VOL- codes for either the Velleman K6710 or K8049 remotes? (I'd be happy with codes from ANY Velleman remote at this point!)

I have a USB-UIRT so I can key in the hex sequence and produce the IR very easily. I could then use that to teach one of my existing learning remotes - and I'm home free!

But I have no idea, without actually having a Velleman remote, how I can get the sequence produced for VOL+ or VOL-.

I will be infinitely grateful to anyone who can help me out with this, or give me any good ideas on how to go about solving it. Thanks!!

Here's the tech info about those commands, but it is beyond my scope of knowledge for generating them. I believe an .irp file could be used in makehex, but I don't how to translate the parameters from this spreadsheet.

@estech:

Thank you so much! The spreadsheet appears to give all the info needed to construct a Pronto hex sequence for each of the Velleman functions. The sequences also appear to be relatively short.

Assuming it works, I'll post the Pronto hex for the various functions for future reference.

OK, as promised. Based on the Velleman specs I built the Pronto hex codes for the keys I needed, Vol+, Vol-, and Mute. I then used Girder and my USB-UIRT to enter the codes on my PC & transmit them to a learning remote I have (you could use Irnhelper or other free software I am sure). This worked fine, and I can indeed now control my Velleman MK164 volume control using pretty much any learning remote in the house.

Here are the tested & working codes:
Vol+: 0000 006E 0000 000B 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 011E 001A 00C0
Vol-: 0000 006E 0000 000B 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 00C0 001A 00C0
Mute: 0000 006E 0000 000B 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 011E 001A 011E

If you need the codes to repeat on being held down, I found you could tack on a delay at the end of the transmit, and according to the specs it must be > 55ms. I bumped that up a little to be safe. So for example, the Pronto code for Vol+ with delay at the end would be:

Vol+: 0000 006E 0000 000C 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 011E 001A 00C0 0001 0B00

This worked well when learned by one of my remotes, not as well on another. However, the "one-click" codes worked on everything.

Since I learned how the Pronto codes work just about 2 days ago, I do not vouch for these codes being in any way correct or perfect or whatever. I can simply tell you they work, hopefully this saves someone all the trouble I had to go through.

Very impressive.

I wrote Makehex, so if I thought I understood those Velleman specs, I could trivially write a .irp file to cause MakeHex to generate all the Pronto Hex strings.

But I looked at those specs and saw several details for which there might be ambiguity in their meaning. That gets hard to deal with since I don't have the actual device to test. So I didn't try.

I haven't looked at the details of your working Pronto Hex strings, but those must resolve any ambiguity in the meaning of the spec (or they wouldn't work) so if there remains any reason to have the .irp file (rather than just the strings you posted), someone should ask and I'll write it.


That's a strange choice for controlling the delay. I expect what you wanted was

0000 006E 0000 000C 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 011E 001A 00C0 001A 0B00

or maybe

0000 006E 0000 000B 001A 011E 001A 00c0 001A 00c0 001A 00c0 001A 00C0 001A 00C0 001A 00C0 001A 011E 001A 00C0 001A 011E 001A 0BC0

Could you check how those behave?

Hi,

as I'm searching for the MUTE code out of a Velleman k8049 to control a IR Remote Volume Control, I checked your codes and they just don't work.

Here are the Keyfob captured codes (Omniremote on a PalmV that replicates the learned codes absolutely well) for:
Volume up
0000 006E 000C 0000 0023 011D 001E 00BE 001E 00BE 001E 00BE 001E 011D 001E 0122 0019 00C3 001E 00BE 001E 00BE 001E 011D 001E 011D 001E 0000
Volume dn
0000 006E 000C 0000 001E 011D 0023 00BE 001E 00BE 001E 00BE 001E 011D 001E 011D 001E 00BE 001E 00BE 001E 00BE 001E 0122 001E 00BE 001E 0000

I'd need the MUTE one, and my two buttons rc won't do it :).
Could you eventually capture that sequence with any facility and post it here ?
Many thanks

The IR signals you've learned are in the format shown in the spreadsheet linked in post #2, but the your remote is sending Device =1 with Vol+=35 and Vol-=34. The signals in post#4 (said to be tested) have the same format, but are Device 0, with Vol+=10, Vol-=8, and Mute=11.  I think that the component you're trying to control and the OP's are different

The Velleman format allows for 7 device numbers, and 64 function numbers, so Mute could be a lot of possibilities.

However, I suggest you try the following Pronto Hex: Please first test the following hex codes for Vol+ and Vol-, which are very similar to your learned codes. If they don't work, there's no need to try the potential Mute codes.

Here's the IRP file I used with MakeHex to generate these.  I find the MakeHexGUI to be a convenient front end for MakeHex.

Hi 3FG,

many thanks for your reply. I am not definitely good in programming..and pls try a bit more if have a minute :)

I copied ALL your posted codes assigning them to available Keys on the Palm, and I can confirm the Vol+ and Vol- are working, but step by step, I mean there's not "dynamic increment" keeping pressed the vol+ vol-. Every click gives a step up/down.

All the other codes are not even causing the IR Receive LED to blink (confirming reception of a sequence), so no MUTE found yet. I'd like to keep on tryin' :)

For your information, in the Velleman Forum, I got these details about K8049 Remote Control needed to MUTE my lovely volume control (15 Channels):
- CHANNEL # 4
- Mute = Button 1
- Volume UP = Button 3
- Volume DOWN = Button 5

In case you'd find the solution, a beer paid, by each fellow in the same situaition :)

Well, the search function can be very useful at times......

Mute Device Code: 0 Function: 11
0000 006E 0000 000C 001A 0110 001A 00B5 001A 00B5 001A 00B5 001A 00B5 001A 00B5 001A 00B5 001A 0110 001A 00B5 001A 0110 001A 0110 001A 081A

This thread  has Vol+, Vol-, and Mute as learned.  The learns aren't perfectly done, but we can see that Vol+ and Vol- match the ones you learned.  The Pronto Hex for Mute above is cleaned up from the incomplete learn in the thread. 

I don't know how to make the Volume signals repeat when you hold the button down.  One possibility is to shorten the last number from 081A to something shorter  perhaps 0600 or 0400.  It may also be that the method you're using to get these IR signals into a remote doesn't preserve the repeating capability.

By the way, I included links to MakeHex and the GUI program in a previous post.  You should be able to use those to make any combination of device 0 through 7, and function number 0 to 63.  That way you can try any valid IR signal.

Hi 3FG,

you're a real IR HERO !
The code provided is just working perfectly.

Many thanks for the time you spent. Hope I would be able to return the favour.

Great site RemoteCentral !!

With regards
