hi,
I have a pair of RF modules and I want to test them for proper working. Tell me a way out. And also mention about the antenna I should use. As according to the data sheet I am using a single core wire of length 17cm. If it is ok then do tell me how to get 50 ohm antenna from a single core wire?
Thanks in advance

You can directly conect dout of HT12E and din of HT12D and both grounds.
Check VT pin when you send input from 12E, for valid o/p it will give high otherwise low.
