I/O Connections for the IMX8

Table B-1
Cell Cable Connector
Pin Name Use
1 Working Sense (WS) Connected to the working electrode in cases where the
system potentiostat uses a differential electrometer. This pin
can be left open when the IMX8 is used with a potentiostat
that uses a single-ended electrometer.
2 WS Shield The shield for the working sense input. Left open at the cell
end of the cell cable.
3 Working Electrode (WE) Connected to the working electrode. The cell current flows
through this pin.
4 WE Shield The shield for the working electrode input. Left open at the
cell end of the cell cable.
5 Ground The system potentiostat’s ground. It can be used to shield
the cell if very low currents need to be measured. Also
recommended as a shield for the counter electrode cable.
6 Reference Electrode (REF) Connected to the reference electrode.
7 REF Shield The shield for the reference electrode cable. Left open on
the cell end of the cell cable.
8 Counter Sense (CS) With a potentiostat, used to sense the potential of the
counter electrode. Allows accurate ZRA mode even with
significant cell current through counter lead’s resistance.
9 Counter Electrode (CE) Connected to the cell’s counter electrode. The cell current
flows through this connection.
Normal Cell Cable Connections
Normally you can use one of Gamry Instruments’ standard cell cables to connect each channel’s connector to
its cell. Gamry supplies cables that are 1.5 m, 4.5 m, or 9 m in length. Special-purpose cables are also available.
The standard cell cable terminates in banana plugs and one pin jack. Table B-2 identifies each terminal of the
cable and its connections to the cell.

Normal Cell Cable Connections
Color Type Name Normal Connection
Blue Banana Plug Working Sense Connect to working electrode
Green Banana Plug Working Electrode Connect to working electrode
White Pin Jack Reference Electrode Connect to reference electrode
Red Banana Plug Counter Electrode Connect to counter electrode
Orange Banana Plug Counter Sense Connect to counter electrode
Long Black Banana Plug Floating Ground Leave open or connect to a Faraday shield
Short Black Banana Plug Chassis (Earth) Ground Leave open or connect to a Faraday shield
The working electrode is the specimen being tested. You make two connections to the working electrode. One
of the two connections, with the blue banana plug, is used to sense the voltage at the working electrode when
