8 Getting started
Before connecting the device to a network or PC, first ensure that it is properly connected to a
power supply, otherwise it may cause damage to other equipment.
The mbNETFIX can be operated in two modes (see chapter 4).
During the initial commissioning and after each factory reset, the mbNETFIX is always set in
Bridge mode, with active packet filter in both directions (Security By Default).
The packet filter can be switched INACTIVE by means of activating input 1 (High 8 – 30 V
DC).
You should choose this preference on input 1 if any of these apply to you:
If you want to operate the mbNETFIX as a bridge
and
want to make the configuration at a later time
and
want to do the installation now
and
do not want to influence the existing network
OR
Activate the learning function of the mbNETFIX in order to be able to read the learned net-
work traffic later during the configuration.
