Sync Port - Gamry Instruments Interface 1000 Operator's Manual

isolation. Interface 1000s with instruments that start with 06001 or higher also include an auxiliary voltage
output that can provide voltages from 0 to 4.096 V.
A full description of this connector is in Appendix C of this manual. This appendix includes details such as
connector pin-out, output and input voltage levels, and full signal descriptions.
The following list is a short description of the signals in the User I/O Connector and their uses:
A 12-bit D/A converter used to set "continuously variable" settings such as electrode rotation rate on a

rotating disc electrode.
Four digital outputs can be used to turn on external devices under control of an Explain experimental

control script.
Some of Gamry applications assign three of the digital outputs to control stirring, flow of de-aeration

gas, and formation of mercury drops on a mercury-drop electrode.
Four digital inputs that can be read in an Explain experimental control script.

An analog output voltage. The output is generated by a 12-bit digital-to-analog converter with an

output span from 0 to 4.096 V.
This connector includes a 5 V power supply that can provide up to 50 mA of current for external

circuitry.
Caution: Floating operation of Interface 1000 can be compromised by improper
connections 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.

Sync Port

The Sync Port is used when several Interface 5000 instruments need to be operated with a common clock and
simultaneous data-acquisition. It is an 8-pin mini-DIN connector.
Simultaneous operation is only required when several instruments are connected to a single electrochemical
cell. Examples include rotating ring-disk voltammetry, series flow cells, localized EIS systems, and
electrochemical microscopy. In these examples, data-acquisition starts and stops on all the system's
potentiostats simultaneously, and any excitation signals are closely coupled to data-acquisition.
Simultaneous operation is generally not required when instruments are connected to different electrochemical
cells. A good example is parallel testing of batteries. You might want to start a number of tests simultaneously,
but the tests need not remain synchronous and they can end independently.
A full description of the Sync Port is in Appendix C of this manual.
