SECTION 2. INSTALLATION
WARNING!
Static Sensitive Connectors! During the installation process and whenever
changing cables to the Knox ProSwitch inputs and outputs, use extreme caution
to avoid conducting static electricity to any inputs or outputs including video,
audio, and RS232.
DC Offset Warning! Connect standard video and audio inputs and outputs
only. Do not connect input or output signals with a positive or negative dc offset.
Chassis Ground is Earth Ground Do not connect video or audio cables with induced or direct-connection potential on the shield.
2.1 INTRODUCTION
This section provides the information required for installation of the
ProSwitch into its operating environment.
. . . . CAUTION . . . .
The ProSwitch is designed to work in standard video and audio
systems. Operation in other environments may harm the ProSwitch
or associated equipment.
2.2 UNPACKING AND INSPECTION
Unpack the ProSwitch carefully and verify that the serial number matches the
number quoted on the packing list. Before installing it into a system, check the
outside of the unit carefully for signs of damage and check that none of the
fasteners have come loose. Check that the power module is also present and
marked for use with the ProSwitch product.
2.4 VIDEO CONNECTIONS
Connect up to sixteen (eight for the GAMMA, DELTA, and EPSILON
versions) video sources (cameras, videocasstte players, RF demodulators, stillstores, character/graphics geneators, etc.) to the input BNC or Y/C connectors
marked VIDEO INPUT. Inputs are automatically terminated in 75 ohms. You may
terminate unused outputs in 75 ohms.
Connect one or two destination devices (monitors, VCRs, LCD projectors,
displays, RF modulators, etc) to the BNC or Y/C connectors marked VIDEO
OUTPUT. Be sure that all destination devices are terminated at 75 ohms.
Do not connect a SOURCE of video to any of the video OUTPUT connectors.
2.5 AUDIO CONNECTIONS (ALPHA or BETA versions only)
Connect up to sixteen unbalanced or balanced audio sources (mikes, videocassette players, RF demodulators, tape/CD players, ect) to the left and right
channel RCA or Phoenix connectors marked AUDIO INPUT. Inputs are high
impedance (100K) for unbalanced sources, or 600 ohm (bridging) for balanced
sources.
2.3 INSTALLATION
The ProSwitch is designed to be mounted in a standard 19" rack panel; it is
5.25 inches, or three standard units, high. Choose a space in the rack which is
convenient for all the cables and mount the unit using standard rack bolts. Connect
the output of the ProSwitch power unit to the power connector at the right rear (as
viewed from the back of the panel) of the ProSwitch and plug the power unit into a
grounded AC power outlet of the voltage and frequency specified on the power
unit. There is no power switch on the ProSwitch; it is designed to be ON at all times.
(If it is desirable to have the ProSwitch powered down regularly, connect the power
module to a switchable AC power strip.)
