Clear-Com HX System Frames - Manual (Page 11)

3.1.2 Select locations for the system components
Select locations for the Eclipse HX matrix frame, interface cards, interface modules, user
panels, PC, and any other system components.
The Eclipse HX (matrix frame) is the central connecting point of the system. All other
devices are connected, either directly or indirectly, to the matrix, and this central role must
be accounted for in your system topography.
Tip: For additional information about locating the Eclipse HX matrix system, see
4 Locating System Components.
3.1.3 Determine cabling and wiring scheme requirements
The Eclipse HX system requires shielded category-5 (CAT5) cable with RJ-45
connectors. All Eclipse matrix frames have built-in RJ-45 connectors.
Wiring schemes
Different wiring schemes are required, depending on the intercom device / system
component that is being connected.
For example:
System component Connections
External computer
(PC) for EHX
The Eclipse HX configuration software runs on an external computer
(PC). The computer is normally connected to the matrix frame using
the LAN1 connector (a standard RJ-45 Ethernet connector).
For Eclipse HX-Omega, Eclipse HX-Median and Eclipse HX-PiCo, a
ferrite core must be added to the socket end of each Ethernet cable
to comply with European EMC standards. A suitable ferrite core is
Würth Electronik part: 74271132.
Shielded CAT5 cable is recommended for Electro Magnetic
Compliance in EC countries.
Note:
LAN1 is the default connector on the matrix frame . The LAN2
connector (which is also a standard RJ-45 Ethernet connector) is
unconfigured when it leaves the factory and must be enabled in EHX
before it can be used.
Tip: Connecting through an Ethernet network enables one or more
matrix frames to be controlled through one or more computers on a
network. For more information, see 6.2 Connecting the matrix
frame to a PC running EHX.
You can also use the supplied DB-9 cable or a commercially
available shielded RS-232 cable. For more information, see
6.2 Connecting the matrix frame to a PC running EHX.
