How to get double wire CAN from SPC5?

[PSing.5]

SPC5Studio asks for a TX and RX pin. I selected CAN 1 TX and RX pins and connected them to CAN 2 RX and TX pins I chose (I tried all manner of connections). I am trying to get CAN 2 to send a message. On the output I see a 0 to 5 V signal instead of 0 to 2.5 V and another of 2.5 to 5 V. How do I get two wire CAN? I think I am missing a concept here, can someone please help me.

I am trying to use SPC560B discovery board.

To anyone reading this in the future, the answer to my question was the SPC56 DIS board does not come with a transceiver to produce a CAN_H and CAN_L.
