This item is a wireless 4 channel remote controlled module with a battery operated transmitter fob. The fob has 4 individual buttons which, when pressed, will trigger one of the 4 digital output pins on the receiver module. When no buttons are pressed all 4 digital pins will remain low (0V). When one of the transmitter buttons is pressed the appropriate output pin on the receiver will go high (5V) and will remain high until the button is released.

These units are based on the PT2262 & PT2272 315MHz transmitter and receiver IC which means they are compatible with our 315MHz PT2262 wireless transmitter/receiver module. See items HCMODU0040 & HCMODU0041.

The transmitter module includes a 12V 23AE alkaline battery and the receiver module can be powered by a single 5V DC supply.


Notes:

To obtain maximum receiver range an external antenna should be attached to the ANT pad on the receiver module. We recommend a length of single core wire measuring 23.8cm (1/4 wavelength) in length.

This is a short range device operating in the 315MHz spectrum. As with all wireless transmitters please make sure this device is legal to operate within your country.

Hi, The info page on this item includes..
Receiver: 4 Channel module capable of receiving a trigger signal from multiple transmitters (Note only one channel can be activated at any one time).

I have two sets of this but they do not cross trigger. Is this something I can tune? If so how do I do it?
Thanks for your help
David

HCWILS0003_Address.png
To set them to the same address there is a set of 8 pins on the underside of both the transmitter and receiver PCBs. I've attached an image to show you where they are. You'll also see that there is a track running above and below the pins. To set an address each of the 8 pads can either be left unsoldered (floating), bridged to the top track (logic high), or bridged to the bottom track (logic low). If you solder them all in the same sequence they will have the same address. Hope that makes sense.
