more stringent than for thick coaxial cabling. Thin coaxial segments have
a maximum distance of 185 meters and each segment can support up to
30 stations.
Twisted pair
cabling
10BaseT
If your network is setup using twisted pair (or telephone) wiring then in-
dividual stations are attached to the network through UTP (unshielded
twisted pair) connectors. A UTP connector is a telephone type (RJ-45)
connector also known as a western plug. A twisted pair cable connects
the UTP port of each station on the network to a central 10BaseT concen-
trator. You can attach the V!CAS to your ethernet using the 10BaseT port.
1. Attach a twisted pair cable to your V!CAS by inserting the 8 pin RJ-45
jack into the twisted pair port on the back plane marked 10BaseT.
2. Make a small loop into your twisted pair cable as close as possible to
the V!CAS and attach a ferrite to it.
3. Attach the other end of the twisted pair cable to an input port of your
concentrator

Note:
You must use a ferrite with your twisted pair ethernet
cable. Otherwise the V!CAS may produce a higher
amount of electromagnetical radiation and therefore
possibly cause interference with other devices.
