Hello,
I bought the 315MHz RX TX pair from cytron, but I can't for the life of me get them to work.
At the moment I've connected the transmitter to Vcc (5V) and Gnd; for the antenna I used a (roughly) 24cm single core copper wire, and for the data I've put in a 40kHz square wave from an oscillator.
On the receiver side I've also connected to 5V and Gnd, and I've plugged the RX pin into an oscilloscope.
Now what do I do with the antenna for the receiver? I see only two holes, one marked "ATN" and the other "GND". Without anything connect to them I see a random square wave appearing on my output. I've tried touching the ATN pin with another 24cm wire, but nothing changes. I tried disconnecting the transmitter - same noisy sorta signals.
What seems to be the problem? How am I supposed to wire the antenna? Is these something wrong with my set up? Some help will be most appreciated. =)
Thanks.
