Configuring the EVL (Ethernet Virtual Group)
What is an EVL?
An Ethernet Virtual Loop (EVL) allows a group of IP network connected NetAXS-123
controllers to be managed as a group, through an embedded Web Server residing on one
of the controllers.
Up to 16 controllers may be grouped into an Ethernet Virtual Loop.
The grouping is known as a Virtual Loop since the administration paradigm is similar to an
RS-485 loop.
Network Requirements
The controllers must be connected to a common IP sub-network that provides dynamic
address assignment through DHCP.
DIP Switch Settings (EVL Mode)
When a NetAXS-123 panel is used in EVL mode, DIP (dual in-line package) switches 1-5
are not used to identify the panel. The panel is identified by its MAC address.
TIP!
When setting up an EVL loop, create a list of MAC addresses for all Panels and what doors
they control. This will be useful later when the panels are configured.
