Note: Suitable existing wiring could be also be used for the room bus. Contact your local
representative for further information.
3.2.1 Ethernet LAN Cable
The cable required for the Ethernet LAN must comply with the specification TIA/IEA 568-A Category 5
or higher. This is a standard 4 x unshielded twisted pair (UTP) solid bare copper with a diameter of 24
gauge (0.5mm).
Table 1. Recommended Ethernet LAN cable
Caution: The maximum length of the Cat 5 (or higher) Ethernet LAN cable is 328 feet/100
meters.
3.2.2 Room Bus Cable
The room bus cable connects the room controller to the associated teleCARE IP peripherals. It consists
of four wires which carry 5.5 volts, Data, Voice and Ground.
The recommended cable for the room bus is TIA/IEA 568-A Category 5 or higher. It is also acceptable
to use 2 x twisted pairs of solid copper wires each 0.10in (0.6mm) diameter. The table below shows
the recommended cable types with the preferred cable type in bold italics.
