removed before the matrix is powered up
Note: A shielded cable should be used.
GENERAL-PURPOSE INPUTS (“GP IN”)
The female 25-pin D-type socket labeled “GP IN” connects the Eclipse
Median CPU card to eight general purpose inputs (GPIs).
An external device such as an external foot switch, a panel-mounted
switch, or the logic output of some other device can be connected to
the “GP IN” connector. When the external logic device is activated, it
sends a control signal into the matrix to perform one of several preset
functions, such as turning an intercom panel’s microphone on or off,
muting a microphone’s output, or turning a panel’s speaker off. The
function to perform and the panel upon which it is performed is
configured using ECS.
Note: A shielded cable should be used.
LOCAL AREA NETWORK 1 PORT (“LAN 1”)
The RJ-45 socket labeled “LAN 1” connects a local area network
(LAN) to the CPU card through a standard Ethernet connection. The
green LED indicates the port is connected and the amber LED
indicates activity.
Note: If this port is used a ferrite must be added to the socket end
of each cable. A suitable ferrite is Würth Electronik part:
74271132.
Note: A shielded CAT-5 cable should be used.
LOCAL AREA NETWORK 2 PORT (“LAN 2”)
The RJ-45 socket labeled “LAN 2” connects a second local area
network (LAN) to the CPU card through a standard Ethernet
connection. The green LED indicates the port is connected and the
amber LED indicates activity.
Note: If this port is used a ferrite must be added to the socket end
of each cable. A suitable ferrite is Würth Electronik part:
74271132.
Note: A shielded CAT-5 cable should be used.
CONNECTING PORT CARDS
Each rear-connector panel associated with an MVX-A16 interface
holds the sixteen RJ-45 connectors that connect the matrix to intercom
