WARNING!
Static Sensitive Connectors! During the installation process and whenever
changing cables to the Knox SDI8x8 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 SDI8x8
into its operating environment.

2.2 UNPACKING AND INSPECTION

Unpack the SDI8x8 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 SDI8x8
product. The SDI8x8 uses a +5 volt supply with center pin positive.
DO NOT USE ANY OTHER POWER SUPPLY WITH THE SDI8x8.
Units are shipped with a memory-backed program microprocessor chip which
retains the routing crosspoint information when power is off.

2.3 INSTALLATION
The SDI8x8 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 SDI8x8 power unit to the
power connector at the right rear (as viewed from the back of the panel) of the
SDI8x8 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 SDI8x8; it
is designed to be ON at all times. (If it is desirable to have the SDI8x8 powered down
regularly, connect the power module to a switchable AC power strip.)

2.4 VIDEO CONNECTIONS

Connect up to eight SDI video sources to the input BNC connectors marked
VIDEO INPUT. Inputs are automatically terminated in 75 ohms. An Input Carrier
Detect LED will light for each valid SDI input.
Connect up to eight SDI destinations to the eight BNC connectors marked
OUTPUT. Be sure that all destination devices are terminated at 75 ohms. When a
valid input signal has been routed to an output, the CD LED and the Data Rate LED
for that output will light.
Do not connect a SOURCE of video to any of the video OUTPUT connectors.
