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.
Table C-1
User I/O Connector
Pin Name Use
1 Analog Output High The auxiliary output signal (DAC output). The output range is 0
to +4.096 V.
2 Analog Output Low The auxiliary output ground connection (ground)
6 Ground Digital ground
7 Digital Out 0 A CMOS-compatible digital output, connecting device input
current must be below 10 µA
8 Digital Out 1 A CMOS-compatible digital output, connecting device input
current must be below 10 µA
9 Digital Out 2 A CMOS-compatible digital output, connecting device input
current must be below 10 µA
10 Digital Out 3 A CMOS-compatible digital output, connecting device input
current must be below 10 µA
11 Digital In 0 A CMOS-compatible digital input: 2.2 k Ω input impedance
12 Digital In 1 A CMOS-compatible digital input: 2.2 k Ω input impedance
13 Digital In 2 A CMOS-compatible digital input: 2.2 k Ω input impedance
14 Digital In 3 A CMOS-compatible digital input: 2.2 k Ω input impedance
15 +5 V Power, 50 mA maximum current
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.
