Inputs and outputs

The two I/Os can be used either as inputs or outputs.
You can also set different switching levels (TTL or PLC)
for the inputs. On delivery, both I/Os are set as inputs
with a TTL level. Specify the function of the I/Os as
inputs with commands IM1 and IM2, and the function as
outputs with OM1 and OM2.
Notice
The electronics must be operated with a supply voltage
of between 12 and 30 V. Incorrect connections between
the supply and interface cables or the digital inputs/out­
puts can cause irreversible damage.
So you must check the correct assignment of the con­
nections before switching on for the first time.

Trigger function

In Trigger mode (command IMD1), the electronics have
four different trigger functions available:
S Pre-triggering by level
S Pre-triggering by external (digital) signal
S Post-triggering by level
S Post-triggering by external (digital) signal
Gross or net values can be used as input values. The
filter settling time can be optimized by the actual elec­
tronics (command AST).
