8.3 CONNECTIONS
8.3.1 General instructions
The necessary connections on the systems can be summarised in two categories:
 Data Connections
 Power Supply Connections
Data Connections
The data connection between the system devices is established with a UTP cable. As a minimum requirement, it is
recommended to use a UTP cable belonging to category 5E or higher. In the case of RJ45 connections, the same sequence
of colours must be followed on each cable end, and it is recommended to use the sequence of colours according to
Standard TIA/EIA-568-B.
The data connection is between Hub-CPU and between Sensors-Hub.
The maximum length of the connection depends on the supply voltage of the system and on the cross section of the UTP
cable (AWG). For convenience purposes, the reference tables of both connections are provided.
