Output a voltage at the analogue output channel
The EasyPort USB is equipped with two analogue outputs channels, 0
and 1. The MAW command, along with indication of the address of the
EasyPort USB module, the channel number and the value, is used to
write a voltage value.
In this case, the range of values for the analogue outputs is also 0x0000
to 0x7FF8 (32760 decimal).
