and 2
outline the pinouts for the Titan/cPCI and Titan/cPCI Rear I/O connectors or
cable connectors.
Technical Tip:
Please ensure that you terminate signals if your application does not
use them. Failure to do so may result in a loss of a performance on
your Titan/cPCI adapter.

Technical Tip:
Please ensure that you terminate the DCD or CTS signals if your
application does not use them. The common way to do this is to
connect DCD to DTR and/or to connect CTS to RTS. Failure to do so
may result in a loss of performance.
