Where is the hardware connection for TTL 0 on the NI Camera Link Extension board?

In the example project for the PCIe-1473, there is a TTL 0 I/O :

Yet, the user manual only shows TTL 1-8 :

Does this I/O pin exist?

I believe TTL 0 is the small SMB connector at the bottom of the card, below the two Camera Link connectors.
