24 • Initialization & Installation
The initialization procedures of a brand-new NuDAM are shown in the
following sections. The procedures are applicable for initializing
NuDAM-6011/D, NuDAM-6012/D, NuDAM-6013, NuDAM-6014D,
NuDAM-6017, and NuDAM-6018.
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*
1
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
• Power supply (+10 V
DC
to +30 V
DC
) for NuDAM modules
• Administration utility software
Note1: Never Connect the DRFAULT* pin to Vs or power source just left it
open or wired to GND.
Initialization Procedure
1. Power off the host computer and the installed NuDAM-6520. Be
sure of the baud rate of the NuDAM-6520 is 9600 bps.
2. Connect a brand new NuDAM module with the RS-485. Set the
module in Default State by shorting the DEFAULT* pin. Refer to
Figure 2.1 for detailed wiring.
3. Power on the host computer.
4. Power on the power supply for NuDAM modules.
5. Use the NuDAM Administration utility to configure the address ID,
Baud rate and check-sum status of the module.
