
Trigger In and Trigger Out are techniques
programmed into the experiment protocol. . Trigger
In can be used to start or stop an electrochemistry
technique. For this, another instrument must send
a trigger to the instrument. Trigger Out can be sent
at the beginning or the end of the experiment. It is
used to start or stop an experiment on another
instrument.
The Trigger signals have high and low levels:
+ 3.5 V < Trigger high level < + 5 V
0 V < Trigger low level < 0.8 V
Fig. 79: Structure of the DB9 connector.

Analog Out is used to control an external device (1 mA max).

Analog In1 and Analog In2 are general analog inputs used for auxiliary signal
(voltage) recording. Activate Record Aux1 and Record Aux2 in the cell characteristics
window to record these variables in the data file.
±10 V max, accuracy: 16 bits resolution with automatic ± 2.5 V, ± 5 V, ± 10 V ranges
for Analog In1, ±10V for Analog In2, Input impedance: 1 MΩ/GND + 10 kΩ in series.

E monitor is a voltage analog output that can be used to inspect E
we
with an
oscilloscope. The output signal is reversed with respect to the software measured
values.

I monitor is an voltage analog output that can be used to inspect I with an oscilloscope.
The current to voltage conversion depends on the Irange selected:


OPEN In is an external Trigger signal (active low) that opens relays to Open Circuit
and stops the experiment performed on the cell. This may be used as an emergency
stop of the experiment that is triggered by an external monitor/event.
