Using CAN on STM32F4 discovery

Hi,

I'm trying to get my two discovery cards to communicate using CAN. It works perfectly when the transmitting card is in Loopback-mode and the receiving card is in Silent-mode, but when I change them to Normal-mode nothing works.
I've read about something called a CAN transceiver, is that something thats already on the discovery card or do I need an external component? Is there some way to make it work without the transceiver?
