Hi guys (first post)
I have a problem setting up a simple pair of RF transmitter/receivers (here's the datasheets; Transmitterand Receiver)
I've got an RS232 connection from my pc set up through a max232 chip, putting out reliable serial data (I've checked this by reading it back INTO my computer again and monitoring). I've wired up the transmitter as the datasheet says - taking the output from my max232 into the data in pin of the transmitter. My problem is that nothing is being received at the receiver (also wired as stated).
I don't have an oscilloscope to test the transmitter's antenna pin, but nothing else I connect to it on the offchance (like LEDs etc) seems to be getting anything on that pin, so I'm worried that no radio signal is coming out of the transmitter...
Any help? Has anyone used modules like this before?
Thanks
