Clock Modes
The VERSA COMM+4.LPCI employs a unique clocking option that allows the end user to select from divide by 4,
and divide by 1 clocking modes. This mode is selected at E1.
To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, … 115.2K Bps) place
the jumper in the divide by 4 mode (silk-screen DIV4).
