Appendix C: I/O Connectors

The Interface 1010 includes several I/O connectors other than the Cell Connector described in Appendix B.
The details of these connectors are described here.

User I/O Connector

This connector contains a number of signals used to interface the Interface 1010 to external apparatus. It is the
miniature 15-pin female D-shaped connector on the rear panel of the Interface 1010.
Caution: The ground pin (pin 6) on this connector is earth ground and the D-connector
shell is the Interface 1010 Floating Ground. Improper User I/O connections can damage an Interface
1010 that is connected to a high-energy cell containing earth-grounded terminals.
Caution: Floating operation of the Interface 1010 can be compromised by improper
cables to the User I/O connector. We do not recommend use of standard 15-pin shielded cables with this
connector. Custom cables with the shield connected to pin 6 of the D-connector are preferred.
The pin out of this connector is shown in Table C-1.
