CONNECTING TO GENERAL-PURPOSE INPUTS
(GPIS)
The female 25-pin D-type socket labeled “GP IN” connects the Eclipse
Median CPU card to eight general purpose inputs (GPIs).
You can connect an external logic device–such as an external foot
switch, a panel-mounted switch, or the logic output of some other
device–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. You choose the function to perform and the panel
upon which it is performed from the assignment program.
CONNECTING TO A LOCAL AREA NETWORK
(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.
If you use this port, you must add a ferrite to the socket end of each
cable. A suitable ferrite is Würth Electronik part: 74271132. “
CONNECTING TO A SECOND LOCAL AREA
NETWORK
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.
If you use this port, you must add a ferrite to the socket end of each
cable. A suitable ferrite is Würth Electronik part: 74271132.
CONNECTING THE PORT CARDS
Each rear-connector panel associated with a port card holds the
sixteen RJ-45 connectors that connect the matrix to remote intercom
panels and interfaces. Each front-installed MVX-A16 port card requires
a corresponding rear-connector panel. Blank panels cover unused
slots.
Port Numbering
Each port connector has an numeric designator. The port’s location on
the backplane grid determines its port designator:
• Port rows are numbered 1 through 16.
