I cant get the PC DNC Lite on my Turbocadcam v14 to send to MX2

I cant get the PC DNC Lite on my Turbocadcam v14 to send to my MX2. I have a terminal that was sent to me by XYZ Machine tools that works fine but it has no DNC. I have managed to send g codes from the MX2 to the PC DNC Lite but not the other way. Can anyone help please. Thanks Grant
