SECTION 2. INSTALLATION
Static Sensitive Connectors! During the installation process and whenever changing
cables to the Knox Chameleon64i inputs and outputs, use extreme caution to avoid
conducting static electricity to any inputs or outputs including video, audio, and RS232.
DC Offsets Not Allowed! 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
Chameleon64i Routing Switchers into their operating environment.
2.2 UNPACKING AND INSPECTION
Unpack the Chameleon64i Routing Switcher 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.
2.3 INSTALLATION
The Chameleon64i Routing Switcher is designed to be mounted in a standard
19” rack; it is 15.75 inches, or 9 standard rack 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 power plug to a grounded AC
power outlet of the voltage and frequency specified on the identification tag. There
is no power switch on the Chameleon64i; it is designed to be ON at all times. (If it is
desirable to have the Chameleon64i powered down regularly, connect the power
plug to a switchable AC power strip.) The AC Power cord is the disconnect device
for the Chameleon64i.
WARNING! Take the following precautions
when making connections to the Chameleon64i.
2.4 VIDEO AND AUDIO CONNECTIONS
Inputs:
The input connectors are BNCs for video and RCAs for unbalanced audio.
Input connectors are on the upper 2/3 of the rear panel. Video connectors are on
the left and audio connectors are on the right as viewed from the rear of the unit. In
most cases the full complement of sixty-four video input connectors and 128 for
stereo unbalanced audio are present, even if the crosspoint cards are configured
for fewer inputs. Note that the input connectors are on two tiers — 1-32 are on the
top, and 33-64 are on the bottom.
Video inputs are automatically terminated in 75 ohms.
For unbalanced monaural audio operation, use only the LEFT channel inputs.
Outputs:
The output connectors are BNCs for video, and RCAs for unbalanced audio.
Output connectors are accessible through the bottom third of the rear panel. Each
card will have 16 output connectors for video or mono audio, or 32 for stereo
unbalanced audio cards. Outputs are numbered from 1 to 16.
Be sure that all video destination devices are terminated at 75 ohms.
For unbalanced stereo audio, the first (upper) connector in each pair is desig-
nated as the LEFT output, and the second (lower) as the RIGHT output.
Do not connect a SOURCE signal to any of the OUTPUT connectors.
