3.3 Configuration
There are seven switches which determine the mode of operation. The
different combinations are listed in the table below.
DIP SWITCHES - All dip switch changes will take affect immediately, except
for the baud rate. To change baud rate the unit must be reset(i.e. cycle pwr).
3.4 Predeployment
Always test the altimeter immediately before deployment to ensure that the
unit can transmit and receive acoustic signals and that the system
parameters are correctly set.
