PANEL CONNECTIONS
Each communications channel has a 5 way connector. Each channel can be used to network with other panels by means of
any available interface.
The appropriate interface board for the desired communications media must be installed in all networked panels. A
RS422/422, Fibre Optic or TCP/IP connection may be used.
For redundancy, in the case of RS422/422 and Fibre Optic, interfaces can be wired in the form of a Loop, thus protecting
Data from interruptions or short circuits by creating a bi-directional communications flow. If the panel loses communications
with other elements of the network, it will have the option via opposite path.
RS422/422 may be used for distances of up to 1200m. For longer distances (up to 4,5 km) Fibre Optic Data connections
should be used.
See interface specific manuals for cable requirements on both types of installation.
The following diagram shows the physical connections with RS422 or OPTICAL FIBRE. When double interface connections
are used, two flat cables are supplied. In the end you should have a flat cable for each physical network path.
NOTE
: Make all connections with the power turned off to avoid risk of permanent damage
to the circuit boards.
