Read Rate of Counts on
the right panel is not
available.
Read Rate of Counts on the right panel is sometimes not available depending on the setting of Read Cycle.
When Read Cycle is Custom , it sometimes is unavailable depending on the setting of Trigger Mode.
Only one image can
save.
When Save Image Until is set to New Read Cycle , only last one image is saved.
When saving multiple images, set WebLink - Gear icon - Advanced - Image Storage - Save Image Until to System
Reset .
Additionally, when Image Storage Location was set to FTP , images might not be saved due to the shorter read interval if
Transfer Optimization is set to Speed (Lossy) .
When you want to prioritize the image storage over the read, set WebLink - Gear icon - Advanced - Image Storage -
Transfer Optimization to Accuracy (Lossless) .
How to acquire or
change the settings from
external?
With the serial communications, it is possible to do so using a serial command so called K command.
For each K command, refer to Chapter 3 or later.
Example: Set the exposure time to 1,000 [
μ s].
Command: <K541,1000>
Response: None
As adding “?” to a K command, the setting value will be returned.
Example: Acquire the current exposure time and gain.
Command: <K541?>
Response: <K541,1000,30>
Presently, the exposure time is set to 1,000 [
μ s] and the gain is set to 30 [%].
How can I read multiple
codes in the field of
view?
When the string of codes are different from each other, multiple codes in the field of view can be read.
• Settings
To enable multiple reads, change the value of default
Look for 1 Symbols in Read Cycle at the left on the setup screen.
Or, change the settings below.
WebLink - Gear icon -
Advanced - Read Cycle - Multisymbol - Number of Symbols
• Output order
The output order is practically random because of the order of completed read.
Using the
Configuration Database or Order Output Filter functions with serial commands, up to 10 output order can be
controlled (when symbols satisfy the output conditions).
• Cautions
Multiple reads are not available in codes with the same string.
Is it possible to specify
the output range for
output string? Turn on Output Format at the left on the WebLink setup screen.
With clicking format strings, Output Formatting Editor screen opens.
With enabling Parse Symbol , the output range can be specified.
How to output the same
code only once in
Constant Read state?
To output the same code only once in Constant Read state with V440-F, set the following.
• Gear icon -
Advanced - Read Cycle - Trigger - Mode : Continuous Read 1 Output
• Gear icon - Advanced - Read Cycle - End of Read Cycle - Mode : New Trigger
With the above setting, V440-4 in Constant Read state reads the same code only once and only output it when a code
different from the previous code is read.
When you want to set V440-F so that it can read the same code again after some time passed, set
End of Read Cycle
Mode to Timeout and adjust Read Cycle Timeout .
