RFXtrx433 manager settings for PT2262

[niccodemi]

Hi,

I am using PT2262 modules on my door sensors and recently I got RFXTrx433 adapter. I would like to get it to work but no luck so far. Can anyone please advise if settings are correct and which pins on module have to be shorted?

Are the settings in RFX manager correct? I am not receiving any raw data in RFX manager.

I updated adapter to latest firmware.

Lighting4 can only receive PT2262 codes if the pulse timing is 350 usec. See also chapter 8 in the RFXtrx User Guide.

For 350 usec normally a resistor 3.3 M is used for the PT2262. See page 6  of  http://www.escol.com.my/Datasheets_specs/pt2262_1.pdf‎ .

From your picture it looks like the circuit is using a 4.7 M resistor. It may work to change this resistor to 3.3 M.

You may also talk to the vendor if there is another way to change the pulse timing or to get a module sending with pulse timing 350 us.

Thanks for info. I will check those links and try with 3.3M resistor.

Update

I managed to change resistor to 3.3M and it works. I receive signal with RFXtrx433.

Thanks again for your help.
