Matrix Card Alarm Connector (J16)
An alarm circuit has been provided in the 32X32 Video Matrix Card's
circuitry. This circuit acts as a switch to trigger an optional external alarm
in the event of a controller fault or failure. The controller alarm circuit
supplies a "contact" closure but does not provide a voltage to the external
alarm. The alarm circuit has 10mA current limit. The Matrix Card Alarm
Connector, located on the backplane, allows connection of the Matrix
Card Alarm.
CPU Alarm Connector (J17)
Not used.
Power In/Out Connector (J18)
Power can be supplied to the Cougar Video Routing Switcher by the use
of an externally mounted power supply, by the use of an internal PS70V
Power Supply, or by the use of dual internal PS70V Power Supplies. The
DC Power Connector can be used as DC power input (external power
supply) or as DC power output (internal power supply or power supplies)
to allow the Cougar Video Routing Switcher to power additional video
equipment items.
