2-2 Command Set
Default State
The NuDAM I/O modules must be set at Default State when you want to
change the default settings, such as the ID address, baud rate, check-
sum status etc. All NuDAM I/O modules have an special pin labeled as
DEFAULT*. The module will be in Default State if the DEFAULT* 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.
Therefore, the communication between host and the module will can be
easily set as the same configuration, the initialization of a module will be
possible no matter what configuration is set under operating state.
For ND-6053, ND-6054 and ND-6056, the pin 6 is used for both
DI15(DO15) and DEFAULT*, and also the ND-6063, the pin 6 is used for
both RL8 COM and DEFAULT*. The jumper setting is as below, and the
default setting is DI15(D015) or RL8 COM. When you want to use ND-
6053, ND-6054, ND-6056 or ND-6063 as Default*, you should open the
module case to set the JP2.
