Tips & Notes
• If you have your own network or system administrator for your network (as will probably be the
case in a larger company), please let this person assume the responsibility for connection and
wiring. Do not connect the network switch yourself!
• The twisted-pair cable (also called a patch cable) between the network switch and the device
to be connected should have a max. length of 100m.
We recommend you only use so-called CAT5e cables that are fully wired (all 8 contacts of the
RJ45 connectors are connected 1:1). These can also be used for gigabit connections.
• Never connect a BNC cable directly to the BNC connector on the network switch.
Always connect a BNC T- piece with the BNC connector.
Now, two BNC network cables can be connected to the two ends of the BNC T- piece (or a BNC
network cable and a 50 Ohm terminating resistance).
The same applies to a BNC network card - a BNC T- piece must always be connected first to
the network card’s BNC connector.
• A cable with a minimum length of 0.5 m must be connected between two BNC network cards
or the BNC connector on the network switch. Shorter cables may lead to problems in the
network.
The entire BNC segment should have a maximum length of 185 m.
There must be a 50 Ohm terminating resistor on the two ends of the BNC segment.
If the BNC cable is broken, or faulty at any point (e.g. short circuit), none of the network devices
connected to the BNC cable will work!
• The maximum theoretical data transfer rate of 10, 100 or 1000MBit/s is not usually achieved in
practice. During data transmission, not only data, but also protocol information etc is trans-
mitted, data packages must be repeated or different computers may want to transmit data at the
same time. Furthermore, the data for example may need to be read off the hard disk of one
computer and written onto the hard disk of another computer.
• If the network switch is not supplied with power, all the connections will be out of operation. A
network connection is not possible.
Disposal
Electrical and electronic products do not belong in the household waste!
Please dispose of the device when it is no longer of use, according to the current
statutory requirements.
