Site Preparation and Installation

❏ Provision for up to 100 transceivers (depending on cable
length), via annular rings spaced at intervals of 2.5 m
(approximately eight feet) along the cable.
❏ Termination at both ends by N-series 50-ohm terminators.
The network must have a single ground connection.
The thinnet type of Ethernet cable has the following characteristics:
❏ A maximum length of 167 m (547 feet)
❏ Provision for up to 30 transceivers, regardless of cable length.
Transceivers can be spaced at any desired interval.
❏ Termination at both ends by BNC 50-ohm terminators. As
with standard cabling, the network must have a single
ground connection.
Thinnet cable is less costly than standard Ethernet cable, and is
easier to install due to its greater flexibility. Computing devices that
are equipped with built-in transceivers can be coupled to the
network without external transceivers and transceiver cabling if the
LAN backbone is formed by thinnet rather than standard cable.
Standard cable is heavily insulated and shielded against
electromagnetic interference.
To achieve maximum reliability, use the following cautions when
planning the installation of cables.
❏ Do not run signal cables parallel to AC power cables if they
are within four inches of each other.
❏ Do not install signal cables close to electric motors, power line
regulators, relays, or power supplies.
❏ Avoid laying signal cables close to air conditioners, copy
machines, water coolers, and other similar equipment that
generates power line “noise.”
❏ Do not run signal cables near equipment that generates radio
frequency interference (for example, radio transmitters).
