4.1 Initialize a Brand-New NuDAM
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.
