4.1 Data Rate Multiplier
The DSU-200/300-SIT uses an accelerated UART clock frequency to boost data rates to as
high as 460,800 bits per second. This setting determines the amount of data rate acceleration applied.
It is recommended that the Data Rate Multiplier be left in "Auto" mode unless the application
specifically requires otherwise.
4.1.1 Auto (default)
Select this radio button to allow the USB serial port device drivers to automatically adjust the
clock as necessary. The software application can request any desired baud rate up to 460,800 bits per
second. This setting is suitable for most applications.
4.1.2 Force X1 mode
Select this radio button to limit each serial port to a maximum of 115,200 bits per second. The
software application can request any desired baud rate up to 115,200 bits per second. This setting will
not enhance most applications.
