Baud Rates and Oscillator Value
The 7202e utilizes a 14.7456MHz oscillator, which is automatically entered by the SeaCOM driver under
Windows 2000/XP/Vista/7 operating systems. The oscillator value can be found in the COM port properties
of Device Manager under the ‘Advanced Tab’.
The high-speed oscillator and the UART’s flexible clock prescaler support a wide range of standard and
non-standard baud rates. You simply need to select the appropriate baud rate in your communications
software and the driver will calculate the closest matching baud rate.
When you use the board in other operating systems, the baud rate you select is multiplied by eight resulting
in the actual, faster baud rate. This allows the board to achieve data rates to 921.6K bps.
The following table shows common baud rates, and the baud rates you need to select in your application
running on operating systems other than Windows.
