Appendix C -- I/O Connectors
The Interface 1000 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 1000 to external apparatus. It is the
miniature 15 pin female D shaped connector on the rear panel of the Interface 1000.
Be careful, the ground pin (pin 6) on this connector is earth ground and the D-connector shell is the Interface
1000 Floating Ground. Improper User I/O connections can damage an Interface 1000 that is connected to a
high energy cell containing earth grounded terminals.
Caution
Floating operation of Interface 1000 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.
The pin out of this connector is shown in Table C-1.

Sync Port
The Sync Port is used to interconnect Interface 1000s that must be operated synchronously – with a single clock
and with simultaneous data acquisition. The sync connector is a 7-pin mini-DIN connector located on the rear
panel of the Interface 1000.
Gamry's synchronization system uses the terms Master and Serf as defined below.
Master: The Master potentiostat provides the clock signal used for all potentiostats and provides data
acquisition pulses used to control the timing of A/D conversion. All synchronous multiple potentiostat systems
have only one Master.
Serf: A Serf potentiostat gets its timing information from a Master potentiostat. A multiple potentiostat system
can have up to 7 Serf potentiostats all controlled by one Master.
