10.1 Nortech
Your configuration for communication protocol should be set to “Nortech”.
The Nortech Client application exchanges configuration and monitoring information with the EasyGrid
using the Nortech protocol.
If you intend to connect multiple units to a RS-485 bus, a unique network address must be set to each
unit before installation. Otherwise, you will have to go to each unit location with a portable computer
and configure its network address on-site. The Nortech network address is configured through the
Nortech Client software.
In order for the multiple EasyGrids to work on the same serial bus, each unit must:
Be connected to the other units through the RS-485 interface.
Have a unique Nortech address.
