2.9 Panel network
The panels of the GR-
750x series can be connected and form a network of panels, referenced as “Panel
network”, using the
NET-L
and
NET-R
terminals on the power management board. The maximum number of
connected panels cannot exceed 24. There is the option to enable/disable the networking capability of each
panel as required.
When two or more panels are connected, there is the option to form a
trusted panel network
. Panels in the
same trusted network will synchronize events (automatic process), some settings and point commands are
applicable to all of them simultaneously.
Each panel has its own name, ID, and MAC address. For panel to form a trusted group, all members must
have unique ID. This can be done automatically or be configured manually, depending on what is required
(refer to 5.3.9 PANEL NETWORK for group formation).
The panel network line is monitored for open or closed ring topology (refer to 3.4 Panel network wiring). In the
case of system failure of the panel network controller (MCU), the board will internally connect the
NET-L
with
NET-R
signals, to preserve the communication between the other panels. This is the reason why a closed ring
topology is
strongly recommended
.

The Ethernet/Wi-Fi card provides a website for remote monitoring and configuration of the panel. It is
accessible from any device with browser support if it is connected to the same network as the Ethernet/Wi-Fi
card of the panel. Two different access levels are available (
User
and
Technician
), each with a separate
The html link (URL) for the website is the IP address of the Ethernet/Wi-Fi card in the local network (this can
be found in the
screen and configured from the
screen).
