2-2 Initialization & Installation
Default State
The NuDAM modules must be set at Default State when you want to
change the default settings, including the ID address, baud rate, check-
sum status etc. All NuDAM modules have an special pin labeled as
DEFAULT*. The module will be in Default State if the Default*
1
pin is
shorted to ground when power ON. Under this state, the default
configuration is set as following:
• Address ID is 00.
• Baud rate is 9600 bps.
• Check-sum disable.
• Watchdog timer is disable.
Therefore, the configuration of the host and the module can be easily
set identically and initializing a module will be possible no matter what
configuration is set under operating state.
