In the potentiostat accessory kit a dedicated Output cable, D9 male
–
open, 2m (pn 250.0128A) is supplied. It is advised to use this manufac-
turer-supplied cable for this type of measurements.
For reference, the layout of the analog data out connector is shown in the
table below.

To measure for example the analog signal of cell 1 with an external A/D
converter:
•
Connect the signal wire, lead of pin 1 (V
out 1
), to the analog
measurement channel of the A/D converter.
•
Connect the GND wire, lead of pin 6 (or 7-9), to the corresponding
analog ground connection of the A/D converter.
Digital I/O connector
The potentiostat has one 25-pins digital I/O connector which enables con-
trol of (or by) external equipment. The IO connector contains 18 TTL con-
tacts (5 outputs and 13 inputs, 3.3V CMOS logic), 2 RELAYS (contact clo-
sure) and 1 ground (GND connection).
