Looking to build a unidirectional CAT5e data tap. Answered

I wanted to ensure that data being tapped on the RX ends can not be reversed and used for data TX, ensuring unidirectional transfer. I have the tap made  with Hotside > Hotside (TX->RX-,TX+>RX+)  Coldside > Hotside(RX->RX-, RX+>RX+). I would like to know what I would need to put in between the hotside and the cold side to be able a secure a unidirectional transfer.

Diodes will not work.. Unidirectional will need a threestate buffer.. But that buffer needs some intelligence to select in/out direction which implies a micro processor to catch the first data packet to be detected.. But that is a standard cable switcher..
