I have a Uniden SDS100 connected to a computer, but it is not History Logging.
I found these tips, but I still haven't had any success.
Under Options, I did verify that logging to the history text file or grid display is explicitly turned on.
The computer and scanner are connected, but it just isn't logging.
What shall I try next?
When I shutdown ProScan and use ARC536PRO, it logs fine, so they are communicating.
If ProScan is not writing to your history log, check that the history grid logging option is enabled in Options > Logging > History Grid, ensure your serial/USB connection and scanner type are actively communicating, and verify your designated file save paths in the ProScan Software configuration.

Common Fixes
- Enable Logging Setting: Go to Options -> Logging -> History Grid and verify that logging to the history text file or grid display is explicitly turned on.
- Check Serial/Comm Connection: Confirm that your scanner is fully connected, the correct COM port is selected at the bottom of the logging window, and data is actively refreshing on the virtual display.
- Verify File Paths: Check Options -> History Log Location to ensure the target destination folder exists, is writable, and isn't blocked by Windows permissions.
- Power Cycle Hardware: Turn your scanner off and on again, and ensure it is properly recognized in serial/PC control mode.
