8. Click the
Trigger
button and have the DataMan 370 Series reader acquire image and decode the code. You can
see the results of the code in the Result History panel.
In case you need image enhancement, image filtering might improve the image quality and code readability.
WARNING
:
Do not stare into the beam when adding, removing, or changing cables. Cognex recommends to
disconnect the reader from power whenever you make physical changes to it.
Follow the steps below to connect your reader to power and network:
CAUTION
:
Make sure that the reader is not receiving power before you perform any I/O wiring or adjustments to I/O
devices.
CAUTION
:
Make sure that the Ethernet cable is grounded at the far end. Whatever this cable is plugged into
(usually a switch or router) should have a grounded Ethernet connector. Use a digital voltmeter to validate the
grounding. If the far end device is not grounded, add a ground wire in compliance with local electrical codes.
1. Connect the I/O+RS232+24V cable to your reader.
2. Connect your reader through an Ethernet cable to your network for a network connection.
3. Connect the cable to a 24V power supply.
DataMan 370 Triggering
DataMan 370 readers support the following trigger modes:
l
Self
: At an interval you configure, the reader automatically detects and decodes codes in its field of view. If you
set a higher re-read delay than the trigger interval, there is a code output only once until the code is out of the
field of view for the duration of the re-read delay.
l
Single
(external trigger): Acquires a single image and attempts to decode any symbol it contains, or more than
one symbol in cases where multicode is enabled. The reader relies on an external trigger source.
l
Presentation
: Scans, decodes and reports a single code in the field of view. The reader relies on an internal
timing mechanism to acquire images.
l
Manual
: Begins acquiring images when you press the trigger button on the reader, and continues acquiring
images until a symbol is found and decoded or you release the button.
l
Burst
: Performs multiple image acquisitions based on an external trigger and decodes any symbol appearing in
a single image or within a sequence of images, or multiple symbols in a single image or within a sequence of
images when multicode is enabled. You can control the number of images within each burst and the interval
between image acquisitions.
l
Continuous
: Begins acquiring images based on a single external trigger and continues to acquire and decode
images until a symbol is found and decoded, or until multiple images containing as many codes as specified in
multicode mode are located, or until the trigger is released. You can configure your reader to acquire images
based on the start and stop signal from separate digital IO pulses.
