Need help Nrf24L01+ and arduino mega

I would like to say in advance help would be appreciated.

Ok what I want to do is pretty straight forward. I need to use two arduino mega with the Nrf24L01 transceiver. One ardunio will be the RX an one will be the TX as you know. Now here the thing, all I want to do is simple have the TX configured for a 15 pin high low input which will trigger the corresponding pin on the RX which will have a 15 pin high low output
