The main reason it needs to handshake is that the CAN peripheral in the Jag handles each message based on interrupts... if a message isn't handled before a new message comes in, it will lose the packet and not act on the expected command. To prevent this, the cRIO waits until the Jag claims to be done (via an ACK).
