data to the host. if the data matches and the timer times out, the AV500 will transmit the
data to the host.If the new bar code data is different then the bar code in memory the AV500
will replace the bar code in memory with the new bar code data and transmit the new bar
code data to the host.
•
Distance - First Code/Last Code:
operate the same as time, but the tachometer is used
to measure distance. the AV500 will not transmit that bar code data again until it has not
been decoded for the time specified or the conveyor has traveled the specified distance as
defined here.
Filter Timeout Time
When the Filter Type is selected the Filter Timeout Time option is made available. this option
allows the user to set the time before the AV500 will transmit the same bar code data as the
previous decode. Enter time in milliseconds.
Replicate same code when symbologies don’t match
Click the check ‐ box to transmit the same bar codes when contain the same data but they are
not the same symbology.
Enable Encoder Settings
Click the Check ‐ box to enable encoder settings. The Enable Encoder Settings is used when the
bar code data is compared by distance rather then time.When this option is enabled the
Distance
‐ First Code and Distance ‐ Last Code filter types are made available.
Encoder Settings
Physical Encoder
Select Disable or Enable from the drop ‐ down list:
• Disable: External encoder is disabled, and internal encoder is active
• Enable: A physical encoder is connected to the Encoder input and is enabled
Encoder Step (mm/pulse)
Click to activate the Encoder Step input form. Enter the Encoder Wheel Circumference in
the field provided and select the in or mm option. Enter the Pulses / Revolution in the field
provided (See the table below for values). Click Submit to save the values, or click Cancel to
return to the Operating Mode window.
Encoder Resolution
Displays the encoder/tachometer resolution in pulses per inch (PPI) based on the Encoder Step
calculation. This field cannot be edited.
Conveyor Speed (Max/constant)(m/sec)
When Physical Encoder is Disabled, enter the conveyor speed in meters per second in the field
provided (see formula below).
When Physical Encoder is Enabled, enter the maximum belt speed using the formula below.
Setting the belt speed too high will affect image quality; setting it too low will give you an
exceeded maximum line rate error when the belt exceeds this setting.
Formula: Max conveyor speed x 1.05
Advanced Encoder Settings
The settings are available when Physical Encoder is set to Enabled above.
Direct Encoder
Select Disable or Enable from the drop ‐ down list. Direct encoder is a high ‐ resolution encoder/
tachometer used in start/stop applications.
