Rear Panel (left to right)
A AD Data
Lines / COM
Ports
1–2 or 3–4
Control data is sent via these two BNC
connectors to switching bays, code
generation devices, and accessories that
are part of the matrix switching system.
Use high-speed coax RG59 or
equivalent. Plug a 75-ohm terminator
BNC into the last device.
Adjacent to these lines is a slide switch.
• UP position selects AD data lines 3–4
and COM ports 17–32 (indicated by the
top LED).
• DOWN position selects AD data lines
1–2 and COM ports 1–16 (indicated by
the bottom LED).
• UP/DOWN LEDs on the front panel
indicate the switch position.
The number of monitors, camera, and
camera PTZ functions controlled is as
follows:

1–16 or
17-32
RJ-45 connectors are used to connect
keyboards, alarm interfaces, video loss
modules, port expanders, access control,
and third party accessories.
C
Alarms
Annunciators can connect to normally
open (NO) or normally closed (NC)
contacts depending on requirements.
The relay changes from the NC state if
one of the dual MPCPU’s is not
operating.
The relay will also change if two hot-
switched MPCPUs are set to the same
com port setting (UP or DOWN).
D Thumbnut Turn counterclockwise to release the
MPU module from the port module.
E Ethernet
Connection
LEDs in the connector indicate activity on
the network.
• GREEN solid (Ethernet connectivity) or
flashing (Ethernet activity)
• AMBER ON (Ethernet 100Base-T) or
OFF (Ethernet 10Base-T)
F Video In/Out
BNC
VIDEO IN BNC (top) can be used for
manual snapshots. Connect this BNC to
a matrix switch VOM output dedicated for
snapshots.
Note: Manual snapshots reduce VOM
outputs used by monitors by one. Be sure
to terminate the video line (see Line
Termination Switches below). See
example in Appendix C.
VIDEO OUT BNC (bottom) is not used.
G Line
Termination
Switches
Use to terminate the Video In line, and
the two SensorNet or Manchester
connections. Press appropriate switch
down to terminate.
H RS-422 /
SensorNet
Data
Connector
Default configuration is SensorNet and
can accept up to two SensorNet data
lines (for up to 508 cameras).
• Ch.1 is for 1-254 cameras (camera
numbers 1-254)
• Ch.2 is for 1-254 cameras (camera
numbers 255-508)
EASY CPU software can configure ports
to provide:
• Two connections that can be
independently set for SensorNet or
Manchester data transmission.
• Two additional connections for AD RS-
422/485 that can be independently
configured as RS-232 signals for AD
RS-422/485 distribution panels.
