Appendix C: I/O Connectors
The Interface 5000 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 5000 to external apparatus. It is the
miniature 15-pin female D-shaped connector on the rear panel of the Interface 5000.
Be careful: the ground pin (pin 6) on this connector is earth ground and the D-connector shell is the Interface
5000 Floating Ground. Improper User I/O connections can damage an Interface 5000 that is connected to a
high-energy cell containing earth-grounded terminals.
The pin out of this connector is shown in Table C-1.

Sync Port
The Sync Port is used to interconnect Interface 5000s that must be operated synchronously, with a single clock
and with simultaneous data-acquisition. The Sync connector is a 7-pin mini-DIN connector on the rear panel of
the Interface 5000.
Gamry’s synchronization system uses the terms Master and Serf as defined below.
Caution: Floating operation of the Interface 5000 can be compromised by improper
cabling 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.
