Topologies of network MATRIX.Net
The MATRIX.Net can be set
in a line structure and a line structure with
branch feeder.
All units equipped with DencoHappel MATRIX system can
access this data bus.
The data bus must be terminated at both physical ends to avoid reflections, which
can interfere with data transfer. Switchable bus terminating resistors are inte-
grated on the respective boards enabling safe termination – refer to Chapter
"Connecting MATRIX.Net".
6.12.4
Line structure
The illustration Fig. 6-33 shows the setup of the MATRIX.Net with line structure.
As an example, two groups, each consisting of a control panel and a global mod-
ule, are networked.
In addition, the power supply of the control panel via the controller (terminal 95/
99) is also presented.

NOTICE!
The data transfer cable must be run as demonstrated in Fig. 6-33 so that only
one side of the respective shielding is applied – See “Shielding / Earthing” on
page 90.
