Objective of Initializing a Brand-New NuDAM
All NuDAM modules. except ND-6520 and ND-6510, in a RS-485
network must have an unique address ID, however, every brand-
new NuDAM has a factory default setting as following:
• Baud rate is 9600 bps.
• Address ID is 01.
• Checksum is disable.
• Host watchdog timer is disable.
Therefore, to configure the brand-new NuDAM before using is
necessary, otherwise the address ID will conflict with others. The
baud rate may also be changed according to user‘ s requirements.
The following initialization procedures are need not only for a
brand-new module, but also for a installed NuDAM module. When
the user want to change the setting, the initialization procedure
can also be used.
Initial State
The NuDAM I/O modules must be set a Initial State when you want
to change the default settings of the modules, 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 set as Initial State if the Default* pin is shorted to ground.”
Under this state, the default configuration is set as following:
• Address ID is 00.
• Baud rate is 9600 bps.
• Checksum is disable.
• Host watchdog timer is disable.
Initialization Equipments
• Host computer with an RS-232 port.
