OPERATING MODE
PRODUCT REFERENCE GUIDE 121
Code Filter
Select Enabled or Disabled from the drop-down. If enabled code filter options become
available. The camera offers several different conditions associated to the Continuous Mode
Settings. These different options allows the user to configure the camera to accommodate
Such conditions as reading unique bar code data, restrict reading the same bar code by time
(ms), or by distance (mm).
Filter Type
Select one of the following from the drop-down:
•
None: when None is selected the camera will continue to transmit the bar code data as
long as the bar code is held under the camera.
•
New Unique Code: When selected will read new unique bar codes. The camera stores the
data in a memory location and transmits this data to the host. It will then continue to look for
bar code data. If the bar code data read by the camera matches the data that is stored in
memory, the cameras will not transmit it a second time to the host. If the bar code data is
different, the camera will add the new bar code data to the memory location and transmit
the new data to the host. When the memory if full, the oldest bar code is overwritten by a
new unique code.
•
Time - First Code/Last Code: First Code/Last Code: Since the camera is an area camera
it will acquire images up to 32 frames per second. The first and last option is in respect to the
bar code images found. When the First option is selected the camera will use the first image
with a decoded bar code to start the timer. If the last code is selected, the camera will use the
last decoded image to start the timer. The camera will read a bar code and place the data into
a memory location. It will then start an internal timer. When the camera reads another bar
code it will check the new bar code data with the previous data stored in memory. If the new
bar code data matches any previous data the camera will check the timer. If the time
appointed has not been exceeded, and the data exists in memory, the camera will not
transmit the data to the host. if the data matches and the timer times out, the camera will
transmit the data to the host.If the new bar code data is different than any of the bar codes in
memory the camera will add the new bar code data in memory and transmit the new bar
code data to the host. When the memory if full, the oldest code is overwritten by a new
unique code, regardless whether the oldest code has expired.
•
Distance - First Code/Last Code: First Code/Last Code: operates the same as time, but
the tachometer is used to measure distance. the camera will not transmit that bar code data
again until it has not been decoded or the conveyor has traveled the specified distance as
defined here. When the memory if full, the oldest code is overwritten by a new unique code,
regardless whether the oldest code has expired.
Code Depth
Specify the number of unique codes to be saved in memory and checked against incoming
codes.
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 camera 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.
