ODT-MAC400-* / ODT-MAC401-* / ODT-MAC403-*
Operation
■
Image mode:
How the code is to be read. If
mirrored
is selected, then the
reader expects a mirrored code (read via a deviation mirror).
■
Select parameter file:
A backup file can be loaded into the sensor. Use
the
Browse...
button to select the file and then load it into the sensor with
the
Send
button.
■
Download parameter file:
The settings that you have made can be saved
in a backup file.
■
Set default decoder parameters:
Resets all values to their default values.
Explanation of trigger signal edge and triggers for edge/level:
Trigger signal edge:
The sensor responds to edges, i.e., signal changes
(rising/falling edge) that are triggered by a photoelectric sensor.

Pulse diagram trigger rising edge
Triggers for edge/level:
The sensor responds to a pending level, which means it
initiates synchronous trigger cycles as long as the signal is pending, i.e., image
capture, decoding, image capture, decoding, image capture, decoding.
Automatic sensor start
If
“
Triggers for edge/level
”
mode is activated, it is possible for the sensor to start
running automatically and trigger, if the trigger input wiring is connected
permanently to High (or Low).
Procedure: Triggers for level active and single trigger mode active -> Trigger as
long as level is High.
