2-2 Initialization & Installation
2. 2. Initializing a Brand-New Module
Objective of Initializing a Brand-New NuDAM
All NuDAM modules except NuDAM-6520 and NuDAM-6510, in
an RS-485 network must have a unique address ID, however,
every brand-new NuDAM has a factory default setting as
following:
• Address ID is 01.
• Baud rate is 9600 bps
• Check-sum disable
• Host Watchdog timer is disable
Therefore, to configure the brand-new NuDAM before using is
necessary, otherwise the address ID will be conflict with others
modules because the ID of new modules are identity. The baud
rate may also be changed according to user‘s requirements.
The following sections show how to initialize a brand-new module,
which is applicable for initializing NuDAM-6080.
Default State
The NuDAM I/O modules must be set at Default State when you
want to change the default settings, such as the baud rate and
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 is disable.
Therefore, the communication between host and the module can
be easily set as the same default configuration, the initialization of
a module will be possible no matter what configuration is set
under operating state.
