8.1.4 Set Polling
The polling function allows the device to acquire images based on the parameters you set, including
exposure time, gain, Gamma, and light source. Currently, 2 types of polling modes are available,
including single mode and multiple mode.
Single Mode
Note
●
Stopping the real-time acquisition is required before setting the polling function.
●
After the polling enabled, the device acquires images with its max. frame rate. Once the polling
disabled, the frame rate you set in Acquisition Frame Rate takes effect.
●
The polling function may differ by device models.
Steps
1. Go to Image Settings → Image → Polling Enable, and select Single as Polling Enable.
2. Select one parameter (e.g. Param1) from Polling Param.
3. Set Polling Exposure Time, Polling Gain, and Polling Gamma according to actual demands
4. Select Polling Light Selector according to actual demands, and enable Polling Light Enable.

Multiple Mode
Note
●
The parameter of Best Polling Group Idx is used to display the polling parameter number when
the device recognizes codes after enabling polling. If the polling is disabled or polling parameters
are edited, it displays 1 by default.
●
The rule for multiple-mode polling is that the polling is started from the polling parameter with
Best Polling Group Idx, and then execute other polling parameters you selected in turn. For
example, if the Param3 is the Best Polling Group Idx and Param1, Param2, Param4 and Param5
