Appendix E: Ftdi Speed Adjustments - Prior Scientific ProScan III Manual

ProScan® III Manual
Appendix E – FTDI Speed Adjustments
More recent ProScan III controllers have FTDI boards inserted to increase their
functionality and allow control via USB from Windows 8 and above operating systems.
Some users have reported very minor differences in speed and response time when using
these new controllers.
The response time can be altered in order to increase the speed of response. The default
is 16 ms which may lead to slightly delayed responses. Right click on the appropriate port
and select Port Settings > Advanced Settings. Select a lower latency time (e.g. 2 ms) to
reduce any delay observed.
