Chapter 6: Cell Connections
Cell Cable Overview
The EIS Box has eight channels. Each channel has two Cell Connectors on the front of the EIS Box. The Current
Connections are female 15-pin D-connectors, and the Sense Connections are male 15-pin D-connectors.

Front Panel of the EIS Box
The upper (female) connectors are labeled Current Connector . They carry the cell current between the
Counter electrode wires and the Working electrode wires.
The lower (male) connectors are labeled Sense Connector . They contain only high-impedance inputs used to
sense potentials in the cells.
Gamry’s EIS Box standard cell cables always come in pairs. Each cable has a D-connector on one end, and a
number of leads to connect to electrodes in an electrochemical cell. The D-connector end of the cable is
connected to the appropriate D-Connector on the front of the EIS Box. The male and female cables cannot be
interchanged.
Every EIS Box is shipped with eight pairs of standard shielded cell cables. The Gamry part number for the
Current Cable is 985-00183, and the Sense Cable is 985-00184. They are both 3 m complex cables, with
D-connectors on one end, and color-coded banana plugs on the other end.
Always screw both cell cables into place because cables can fall off the unit if not properly attached. This can be
disastrous if detachment occurs during an experiment.
Ancillary Apparatus
Do not use the EIS Box with ancillary apparatus connected directly to any of the cell leads. Examples of ancillary
apparatus include DVMs, oscilloscopes, chart-recorders, and data-loggers. Ammeters and voltmeters, regardless
of their specifications, almost always create problems when connected to the EIS Box cell leads.
Normal Cell Connections
This section assumes that you are using standard, shielded cell cables. This information does not depend on the
length of such cables.
The cell end of the standard cell cables terminates in a number of banana plugs and pin jacks. Each termination
comes with a removable alligator clip. Table 6-1 identifies the terminals of the cables.
