4.9 Connection to a network panels

It is possible to connect the panels to a network. Each panel in the network must have its own address.
The central panel has address 1 and the sub-panels from 2 to 16. The figure below shows the
connection between them.
The interface cable is bipolar twisted. The connection topology is parallel so the cable should be
passed from one panel to another and there must not be any branches.

They can be connected up 16 panels on a network.

RS-485 is the communication protocol between the panels.
ATTENTION! Resistors 120Ohm/0.5W should be placed at the beginning and the end of the cable. The
total cable length should not exceed 500m. For longer distances a RS-485 repeater should be used.
The cable shield must be connected to the grounding of the panel.
During the installation all sub-panels must first be addressed and then a search of the network must be
conducted from the central panel.
