Please can you explain how I can change this upgrade to select different codes than SAT/1238 and SAT/1563?
Once programmed into the remote how do you actually use it?
Does the Dream setting still work as normal until you do a DREAM/Shift-BACK or DREAM/Shift-FORWARD to selcect the other codes? This would give you 3 code sets on the Dream button if I understand it correctly.

SAT/1238 is the device type and setup code number used for his upgrade.
In the RDF, device types TV=0, VCR/DVD/LD=1, SAT=2. This number goes into the top nibble of the first byte.

The setup code displayed and blinked back by the remote is offset by 30 so 1238-30=1208. Convert 1208 to hexadecimal by entering in the calculator and clicking the HEX radio button. It gets converted to 4B8.

Put those together and you get 2 and 4B8 or 24 B8 as the 2-byte setup code.

The Dream button does not work to change the setup code. It only changes which device mode or slot is used and uses whatever setup code is in it. So to switch back to the original setup code, you have to add the original setup code to the multiplexor.

The following creates a TV/1103 upgrade on the URC-33930 and has 3 setup codes mapped to Vol+,Vol-,Mute.

Code: Select all

Upgrade Code 0 = 0C 31 (TV/1103) Device Multiplex. Vol+=SAT/0031, Vol-=SAT/1238, Mute=VCR/0500
 FE 00 41 20 01 24 B8 11 D6
End

In the same way, is it possible to change the VPT device ?

That all makes sense now thank you. I suspect the FE references the 01 FE multiplex, the only bit I am not sure about is the 00 41 bit. The 00 is on both upgrades you posted but the 41 bit has changed from 21 in your first upgrade. I take it you can make the Vol+=SAT/0031 part any button on the remote.

The 01 from 01 FE is from bit11 of the device upgrade setup code(TV/1103 is 04 31 so setting bit11 makes it 0C 31). The 00 is the digit map reference which is not used in this upgrade. The 41 or 21 byte determines which button map is used to associate the following bytes. 21 uses BOUQUET+/-. 41 uses VOL+/-/Mute. Using 61 would include all 5 buttons. You can see in IR.exe which bytes are associated with which button using the scroll bar in the Devices Tabsheet.

Thanks a lot, I think I understand all that now. I have made my upgrade look like this

Code: Select all

Upgrade Code 0 = 0C 31 (TV/1103) Uses Device Multiplexor Protocol 01FE. BOUQUET+=TV/0238, BOUQUET-=VCR/0500
 FE 00 21 00 D0 11 D6
End

It works fine. I use the TV mode and mapped shift-video to select BOUQUET- which is my DVD and shift-TV to select BOUQUET+ which is back to my TV mode.

The remote should be easy for everyone to use as well. I will tell them if the TV does not work after pressing TV just press shift-TV and it will work

I've tested the 3 device multiplex, and it works very fine too.
For information, is is possible to have more than 5 multeplexed devices ?

I'm still looking for changing my VPT device.
is there any protocole to do it ?

I found that on my AUX device the punch through did not want to work. I just set a key move on AUX for the volume up down buttons to operate the TV volume up down.

I hope that helps.

This is a very useful and informative thread, maybe someone could change the title to make it a little more descriptive for others that might be after the same information.

On my 39930, VPT is working. What i want to do, is a macro that can change the VPT device.
In your case, you can set the VPT device in the IR.exe general tab,
set VPT Device to TV, set VPT status to ON, and set AUX use VPT to YES. It works without keymove.

That is how I have it set but it does not work on AUX for some reason.

Why do you want to change the VPT with a macro?

The volume keys are used with the amplifier, but sometime I need to cut it, and I need the TV volume control. So,that's why I want a macro to do it.

this is strange, my amplifier is on AUX. and VPT works on all devices.

I use VPT on one of my dreamboxes. I have set a shift-vol + and shift-vol - keymove under the Dream setting to operate the original dream volume control in case the dreambox volume is set too low from the web interface. This will in effect over ride the VPT setting.
