5. Installation

Equipment for Installation
A existing RS-485 network
NuDAM modules
DC Power supply (+10V~+30V)
Wires for power, communication and I/O signal
Installation Procedure
1. Configure every single NuDAM module under the
administration utility
2. The baud rate setting and calibration procedure must be
done under the DEFAULT* mode
3. The baud rate and check-sum status must be identity
with the application network. The address ID must not
be conflict with other modules on the network
4. Plug the new module to the existing network
5. Use the NuDAM administration utility to check the
entire network
