Connector Pinouts
Tables 1 and 2 outline the pinouts for the Titan/cPCI 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:
1. 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
