 Select 38400 bps if possible.
A higher baud rate means shorter data output cycle, which results in better course
following performance.
 If the system allows setting of data output cycle, set it to 10 ms to 20 ms.
A longer data output cycle results in lower course following performance. This
may affect the radar performance level and the target tracking performance level.
