Installation Guide
Ethernet Cable Installation
Standard CAT5 Ethernet cable is used to make all connections from the sensors to the concentrator
boxes and from the concentrator boxes to the Server.
Buriable Ethernet cable should be used in all cases where conduit is not available. This type of cable
is rugged, waterproof and rodent proof.
If conduit is available then CAT5
plenum
Ethernet cable can be used. Plenum cable has solid wires
which carry the signal and power over longer distances than stranded wire cables. Note that when
installing the solid wire plenum cable it is very important not to get kinks in the cable. The cable
should be carefully unrolled during installation. Kinks in the wire can cause breaks and internal
signal reflections which will degrade the signal from the sensor.
The Ethernet cable may be buried at any depth desired. Typically the depth should be 3 to 4 inches (8
to 10 cm) to avoid most problems that may come from changes to the ground surface. In addition to
trenching there are specialized tools to make cable installation fast and less disruptive to the ground
surface. Companies who install fiber optic cable for Internet applications have this equipment.
Typically once the cable run length is measured it is best to add another 5% to the measured length.
This extra distance will take care of small variations that might have been missed.
The following diagram shows the direct connection method of connecting Concentrator hubs to the
Server and defined cable length limitations. Cable length limits are due to Ethernet transmission
limits and power transmission limits.
