1.2 General Description
The PESA Cougar Digital Video Routing Switcher offers a reliable low cost
answer to your digital video routing needs. The Cougar Digital Video Routing
Switcher is housed in a 3RU frame providing a small profile for space efficient
installations. The Cougar Frame can be equipped with either a single System
Controller or dual System Controllers. The option of dual controllers provides
seamless transfer of system control in case of equipment failure. The Cougar
Frame can also be equipped with redundant power supplies for maximum
reliability and fail safe operation.
The Cougar Digital Video Routing Switcher is designed with small to mid-range
size routing matrix applications in mind. This cost efficient router is expandable to
a 64X64 size matrix utilizing four Cougar Digital Video Routing Switchers and two
MVDA Combiners. The main matrix components use plug-in circuit cards for
ease of maintenance and component replacement. The Cougar Digital Video
Routing Switcher can be serviced hot, allowing circuit card changes without
powering down the matrix. Board level voltage regulation in the Cougar Frame
eliminates the possibility of a central, single point power failure.
The Cougar Digital Video Matrix Card features easily visible LED indicators for
quick view of critical voltage and circuit conditions. The Cougar Frame comes
equipped with one control port, two RS232 ports, four RS485 control panel ports,
and external alarm connectors for audible monitoring of the operation of the
internal power and controller circuits. Please note that the control port, the
RS232 port, and the four RS485 ports are only active when a controller card is
installed in the Cougar Frame. The Cougar Frame utilizes RS485 looping
interfaces for system connection to remote control panels using standard twisted
pair cables.
The Cougar Digital Video Routing Switcher utilizes the PESA System Controller
for system control. The System Controller provides a user friendly graphical
interface; operating in a Windows 3.1™ personal computer environment. The
System Controller can be installed internal to the Cougar Frame, allowing better
rack space utilization. The Cougar Digital Video Routing Switcher working in
conjunction with the System Controller utilizes PESA's low cost RCP line of
control panels for remote system operation.
The Cougar Digital Video Matrix Card is compatible with digital composite, digital
component, and compressed digital HDTV video formats. The Cougar Digital
Video Matrix card provides automatic input equalization for up to 240 meters of
Belden 8281 cable for data rates up to 270 Mbit/s, and up to 150 meters of cable
for data rates up to 360 Mbit/s.

General
If specified when ordered, the Cougar Digital Video Frame will be config-
ured for the intended system at the factory. Before attempting to install
any frame, matrix card, controller card, or power supply; this section
should be read carefully.
NOTICE
THE COUGAR DIGITAL VIDEO ROUTING SWITCHER CONTAINS STATIC SENSITIVE
DEVICES. CARE SHOULD BE USED WHEN IT IS NECESSARY TO HANDLE THE
INTERNAL CIRCUIT CARDS. IT IS RECOMMENDED THAT A GROUND WRIST STRAP
AND GROUNDING MAT BE USED BEFORE ATTEMPTING ANY EQUIPMENT INSTAL-
LATIONS.
2.2 Receipt Inspection
The Cougar Digital Video Routing Switcher was tested and inspected
prior to leaving the factory. Upon receipt, inspect the equipment for ship-
ping damage. If any damage is found, contact the carrier immediately and
save all packing material.

2.3 Unpacking
The Cougar Digital Video Matrix Switcher is comprised of a frame, back-
plane, a 32X32 Digital Video Matrix Card, up to two System Controller
Cards, and up to two PS70V Power Supplies. Prior to discarding packing
material compare the parts received against the packing list. Carefully
inspect the layers of packing material for any components which may
have been overlooked during the initial unpacking.
2.4 Location
The Cougar Digital Video Routing Switcher may be located anywhere
power is available. However, units should be mounted as close as pos-
sible to their associated equipment to minimize cable runs. Forced air
cooling is provided by a small fans located at the back of the unit. Care
should be taken not to block airflow around these fans. Installation should
be in an area where the ambient temperature does not exceed 40°C
(104°F) inside the equipment rack.
2.5 Mounting
The Cougar Digital Video Routing Switcher is rack mountable in a stan-
dard 19” equipment rack. Sufficient space must be provided behind the
equipment racks to allow for the control cables and power cable. All
mounting holes should be utilized and mounting hardware tightened
securely. As with all equipment installed in a rack, the bottom screw on
each side should be installed before proceeding with the remainder of the
screws. Then all screws should be securely tightened. Support the Cougar
Digital Switcher's bottom while installing it in the rack. Figure 2-1 illustrates
chassis installation in the equipment rack. NOTE: Remove the power
supply retaining screws before installing the Cougar Digital Video Routing
Switcher in an equipment rack.
To install a Cougar Digital Video Routing Switcher in an equipment rack
follow these steps:
1. Align the frame with the slotted opening in the rack.
2. Install the bottom screws first.
3. Install the two top screws
4. Tighten all four screws securely.

2.6 Cabling
Considerable weight will be added to the rear panel of the Cougar Digital
Video Routing Switcher by the control, signal, and power cables. There-
fore, all cables should be strained relieved and secured to racks or other
supporting structures. Failure to provide adequate cable support can result
in cables separating from connectors. If cable runs are to be stored under
an elevated floor, they should be tied to the racks as a guide. If cables are
run along the floor, do not allow them to lay in the work area behind the
racks. Stepping or tripping on the cables may result in connections being
pulled free or wire breakage inside the insulation. The Cougar Digital
Video Routing Switcher should be installed in the equipment rack prior to
attaching cables.
Use the following rules when cabling the Cougar Digital Video Routing
Switcher:
1. Lay all cables in their intended positions, separating control, video, and
power cables wherever possible.
2. Provide proper support for each cable during the cabling process. The
use of tie-wraps is recommended as shown in Figure 2-2.

2.9 System Controller Card Installation
The System Controller Card(s) are installed in the upper left-hand portion
of the Cougar Digital Video Routing Switcher . The Cougar Digital Video
Routing Switcher is designed for the installation of up to two System
Controller Cards. If only one System Controller Card is to be installed in
the Cougar Digital Video Routing Switcher, install it in the upper card slot.
To install the System Controller Card(s) in the Cougar Digital Video Rout-
ing Switcher take the following steps while referring to the Cougar Digital
Video Mainframe configuration drawing on page 6.2:
1. Align the first (primary) System Controller Card with the upper set of
circuit card guides in the upper left-hand portion of the Cougar Digital
Video Routing Switcher.
2. Carefully push the System Controller Card into the Cougar Digital
Video Routing Switcher until the circuit card connectors make initial
contact with backplane connectors. At this point, firmly but carefully
continue pushing the controller card into the frame while making sure
the connectors are properly aligned and that no connector pins are
being bent. Continue pushing the controller card until it is in place and
the connectors are firmly mated.
3. Align the second (redundant) System Controller Card with the lower
set of circuit card guides in the upper left-hand portion of the Cougar
Digital Video Routing Switcher and repeat step 2.
4. Once the System Controller Card(s) are installed in the Cougar Digital
Video Routing Switcher, install the controller card locking brace and
secure it with a twist nut to hold the controller card(s) in place. NOTE:
The controller locking brace may be removed after shipment to ease
the replacement of System Controller Card(s) when necessary.
