3.3 Use of coax filters and attenuator
The transmission frequency of the wanted signal across coaxial circuits is bet-
ween 2 and 30 MHz. It can happen that interference is emitted above this fre-
quency range, which may interfere with the wanted signals of other
applications. In this case, it is advisable to connect the added filter (standard
accessory: part number 69722) with the F-connector of the dLAN 200 DSpro.
The filter can be used in many communication applications, such as CATV, satel-
lite and other systems to filter out unnecessary channels, frequencies or interfe-
rence frequencies.
If the feed signal levels to TVs or CATV tuners are too high, picture distortions
will occur. It is recommended that by inserting an added attenuator (standard
accessory: part number 69723) into the distribution system, the signal is redu-
ced at the customer outlet.
It is recommended to use a high pass filter (not part of the standard accessory)
to decouple the dLAN 200 DSpro signals from the transfer point of the TV signal.
A filter should be used
쎲
when you want to isolate your dLAN 200 DSpro network from the rest of the
coax infrastructure, or to prevent the dLAN 200 DSpro signal from interfe-
ring with other devices that are not included in your network.
쎲
when you want to shield your dLAN 200 DSpro network from interference
by other transmissions in the same frequency range.
쎲
when you want to protect your dLAN 200 DSpro network from interference
by a DOCSIS modem (or other cable modem) In this case, install a filter bet-
ween the cable modem and the dLAN 200 DSpro network.

4 Factory Default dLAN 200 DSpro
Adapter Configuration
All dLAN 200 DSpro adapters are set to run the autoconfiguration process by
default. This process uses DHCP and TFTP to obtain the network settings and the
dLAN 200 DSpro adapter configuration. It also uses a proprietary protocol called
IFCP to learn the management VLAN.
