Is it possible to change remote control?

I know it exist different IR protocols, so maybe not possible in an easy way to change between some types. However I guess that many using the same IR protocol.

 

With $ "cat /proc/stb/ir/rc/type" I can see 21 in Zgemma H7 and 27 in Maxytec.

 

I would like to test Zgemma remote with the Maxytec box. How can I do it?

 

PS. The reson for this test is that the Zgemma remote have very bad coverage. I need to point the RCU directly at the box, else it doesn't work. I would like to find out if it is bad power in the RCU or bad reception in the box.

and now I can answer myself :-)

 

$ echo 21 >/proc/stb/ir/rc/type

You should also be able to change it in the menu. Maybe you have to set first menu level to expert to see this.

I changed on my H7 the IR Receiving head (diode), the RC is OK, now i can aim against walls and RC is still perfectly working

Do you have any details on that? It is a common problem with all Zgemma's, poor IR reception.

try a few, I think my was from broken Vu+, I didn´t by anything, I see in the datasheet

there are two different pinnings, you just have to take care where the ground is, usually middle pin, you see it on the copper board, or test it with ohmmeter, you should have short circuit middle pin -> chassis, take out power supply while testing, the same way you can solder out an used one, you can determine on copper board where the ground is

Thanks, something for a rainy Sunday afternoon (which is not today ).

It is a VS1838B IR receiver. It was a bit strangely mounted. So I bend it and also I cut off the metal cross in front. I think it is better. I haven't tested properly in normal environment. I will see what the user (a friend) will say about it now.
