4. Double-click the 1747-SDN Scanner Module to open the
1747-SDN Module Configuration dialog.
From this dialog, you modify all configuration parameters for the
1747-SDN Scanner.
If you are using an AdaptaScan with v7.0 (or lower) firmware on
a network with 2 or less nodes, change the Interscan Delay
parameter to 20 ms. This will allow the AdaptaScan more CPU
time to process bar code data instead of responding to DeviceNet
polls.
5. Click the Edit Scan List button.
Note: Version 8.0 of the AdaptaScan Offline Programming
Software and firmware minimizes DeviceNet polling interruption
of scanning.
