I am trying to control a tx rx modules with labview with it being connected to the NI elvis II. Once the circuit is made and powered up, the four LEDs on the receiver end will glow by default. The LED corresponding to VT glows only when some data is received. Now whenever you press any switch (on the transmitter end), that particular LED (on the receiver end) goes off. And an additional feature is that the D0-D3s only both circuit can only be operated if A0-A7 of both tx anr rx corresponds and it acts as a switch. I used I/O ports for both the A0-A7s of both circuits and the D0-D3 of the Tx circuit. However, the LED does not light up at all. Pls help!
PS: Ive attached the schematics and the VI that i did. Apparently, based on the VI, i've put an Boolean LED to see if it will only light up if the A0-A7 correspond. But what it does is blink.
