and divide by 1 clocking modes. These modes are selected at switches SW-2.
To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, ... 115.2K Bps) set
switch position 2 to the 'On' position (silk-screen D4). To select the maximum data rate (921.6K bps) set switch
position 1 to the 'On' position (silk-screen D1).
Caution: Do not set both switches in the 'On' position. This could potentially cause damage to the adapter,
and definitely cause a malfunction.
