In systems with more than two stations all partners are wired in parallel. For
that purpose the bus cable must be connected in a continuous
uninterrupted loop.
Via the order number ADAM-8972-0DP10 you may order the bus connector
"EasyConn". This is a bus connector with switchable terminating resistor
and integrated bus diagnosis.

To connect this connector please use the standard Profibus cable type B
according to EN50170.
Under the order no. ADAM-8905-6AA00 Advantech offers the "EasyStrip"
deisolating tool, that makes the connection of the EasyConn much easier.
Attention!
The bus cable has always to be terminated with the ripple resistor to avoid
reflections and therefore communication problems!
The bus connector is provided with a switch that may be used to activate a
terminating resistor.
Attention!
The terminating resistor is only effective, if the connector
is installed at a slave and the slave is connected to a
power supply.
Note!
A complete description of installation and deployment of
the terminating resistors is delivered with the connector.
