Reference 600+ Cell Cable Connector

Appendix B: Reference 600+ Cell Cable Connector
Chapter 5Error! Reference source not found. describes the connections between a cell cable and an
electrochemical cell. This appendix describes the other end of the cell cable.
Multiple pins assigned to the same signal are connected together on the Reference 600+’s Potentiostat
board. If you need to connect this signal outside the Reference 600+, you need a wire connected to any
one of the D-connector pins.

Pin(s)
Signal Name
Use
1
Working
Sense
Connected to the working electrode in most cases (see Chapter Error!
Reference source not found.). This lead has a 403 Ω resistor in the cell end
of the cable. Custom cell cables are likely to require a similar resistor.
2, 14
WS Shield
The shield for the working sense input. Driven to the same potential as Pin 1.
Left open at the cell end of the cell cable.
3, 4, 15, 17
Reference
Shield
The shield for the reference electrode input. Driven to the same potential as
Pin 16. Left open at the cell end of the cell cable.
5, 7, 10, 11,
18, 19, 22,
24
Ground
The potentiostat’s floating ground. Can be used to shield the cell if very low
currents need to be measured. Also used as a shield for the counter
electrode cable.
6
Counter
Sense
With a Reference 600+, used to sense the potential of the counter
electrode. Allows accurate ZRA mode even with significant cell current
through counter lead’s resistance.
8
CBL_ID1
One of four cable ID bits. Used to identify the type of cell cable attached to
the unit. Pull to a logic High through a resistor. Ground to set the bit low.
9
CBL_ID2
One of four cable ID bits. Used to identify the type of cell cable attached to
the unit. Pull to a logic High through a resistor. Ground to set the bit low.
12, 25
Work
Shield
The shield for the working electrode input. Connected to Floating Ground.
Left open at the cell end of the cell cable.
13
Working
Electrode
Connected to the working electrode. The cell current flows through this pin.
16
Reference
Electrode
Connected to the reference electrode in most cases (see Chapter Error!
Reference source not found.). This lead has a 403 Ω resistor in the cell end
of the cable. Custom cell cables are likely to require a similar resistor.
20
CBL_ID0
One of four cable ID bits. Used to identify the type of cell cable attached to
the unit. Pull to a logic High through a resistor. Ground to set the bit low.
21
CBL_ID3
One of four cable ID bits. Used to identify the type of cell cable attached to
the unit. Pull to a logic High through a resistor. Ground to set the bit low.
23
Counter
Electrode
Connected to the cell’s counter electrode. The cell current flows through this
connection.
