2.2 Initializing a Brand-New Module
Objective of Initializing a Brand-New NuDAM
All NuDAM modules, except NuDAM-6520 and NuDAM-6510, in a RS-485
network must have an unique address ID. 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 to
avoid conflicting address. The baud rate may also be changed according to
user‘s requirements.
The initialization procedures of a brand-new NuDAM are shown in the following
sections.
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* 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.
Initialization Equipments
• Host computer with an RS-232 port
• An installed RS-485 module (NuDAM-6520) with 9600 baud rate
• The brand new NuDAM module
