3.3.24 NETWORK | DEVICES WINDOW
This window summarizes the device addresses and resources (output devices/ relays and RTD
inputs) that have been found by the system and can be used for setup.

Update Network Action Button
Pressing this button starts a search/scan for all connected peripheral devices. When the scan is
completed, the window displays all devices and RTDs found connected to the NGC-UIT2.
IMPORTANT: If expected devices or RTDs are not discovered on the first scan, Update Network
may be pressed a second time. If a known device or RTD is not discovered, check for proper
connection to the RS-485 wiring, power at the peripheral device, and possible address conflicts (no
two peripheral devices can have the same address setting).
Use the Update Network button whenever a new device or RTD is added to the system.
To add a new device or RTD, make sure it:
1. Has a unique address
2. Has power
3. Is connected to the RS-485 wiring
Then push Update Network to add the device to the list.
IMPORTANT: Removal of Device - If you remove a device or RTD from the network, using the
Update Network button will not remove the device from memory. You must use the “Remove
Device” button found in the Network|Remove window.
The table below shows the available device addresses for Relay Outputs and RTDs. If module(s)
are installed either in the field or in the NGC-30 panel, they must NOT share the same address as
the NGC-30-CRM/CRMS.
