0..255
Register value for Output amplitude control of selected MILbus
(0 = 0%, 255 = 100%)
Note: The relationship between the physical output amplitude and the
value given with this parameter is nearly linear. The output amplitude
value depends on the adjusted coupling mode.

All API functions return API_OK if no error occurred. If the return value is not equal
to API_OK the function ApiGetErrorDescription can be used to obtain an error
description.
