Connector Pinouts

Tables 1 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.
