SECTION 2. INSTALLATION
WARNING!
Static Sensitive Connectors! During the installation process and whenever
changing cables to the Knox HD-8 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 HD-8 into
its operating environment.
2.2 UNPACKING AND INSPECTION
Unpack the HD-8 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.
2.4 VIDEO CONNECTIONS
Connect up to eight baseband video SOURCES (cameras, VCRs, DVD
players, satellite receivers, RF demodulators, etc.) to the NTSC (yellow RCAs) or
Y/C video input connectors. Inputs are automatically terminated in 75 ohms. It is
not necessary to terminate unused inputs. The input connectors are on the left
rear of the HD-8.
Connect up to eight destination ZONE devices (TV monitors, VCRs, LCD
projectors, RF modulators, etc.) to the NTSC or Y/C video output connectors on
the HD-8. Be sure that all destination devices are terminated in 75 ohms. It is not
necessary to terminate unused outputs. The output connectors are on the right
rear of the HD-8.
Do not connect a SOURCE of video to any of the video OUTPUT connectors.
On-Screen Programming: A ninth composite video output jack can be found
in the center of the rear panel. This jack has the same video content as Zone 1, but
it has a character generator display overlaid on the picture (in the absence of a
video signal for Zone 1, the On-Screen display will have a blue background).
Note: in PAL operation the On-Screen Display will be in PAL if there is a valid
625-line PAL output on Zone 1, but in the absence of a valid Zone 1 output, the
blue screen will be 525-line NTSC.
The Infrared Remote Control accessory is shipped without batteries. It
requires 2 standard AA batteries.
2.3 INSTALLATION
The HD-8 will be connecting a number of SOURCE devices to a number of
destination ZONE devices. Choose a space which is convenient for all the cables
to converge, usually in or near the local zone, ZONE 8. Mount the HD-8 on a
horizontal flat surface or on a shelf in a standard 19" rack panel; it requires three
standard rack units (3U) for clearance. Connect the HD-8 power plug to a properly
grounded AC power outlet of the correct voltage and frequency.

2.6 IR CONNECTIONS
Connect up to eight infrared drive SOURCES collected from the various
ZONES to the stereo miniature phone jack connectors labeled IR Inputs. Inputs are
high impedance (100K). Connect the IR signal to the TIP, or outermost conductor
of the phone plug. A source of +5 volt current is also available through a 470 ohm
resistor at the IR input connectors; connect a low-currrent device to the RING, or
center conductor, of the phone plug. The SLEEVE of the phone plug is common
(ground).
Connect one or more IR emitter-driver devices to the miniature phone jack
connectors labeled IR Outputs. Devices may be terminated with a 1Kohm load.
NOTE: these are unmodulated outputs designed to drive TTL inputs. The driving
signal is on the TIP of the connector; the SLEEVE is common (ground).
An additional IR output jack to the right of Output 8 is a modulated,
cumulative output of all eight IR input signals. It is designed to drive an infrared
LED directly. This output can be used to drive one or more SOURCE machines from
ALL ZONES at once. The driving signal is on the TIP of the connector; the SLEEVE
is common (ground).
Do not connect a SOURCE of IR to any of the IR OUTPUT connectors.
Rear panel LEDs will light to show any activity on IR Inputs or IR Outputs.
2.7 RS232 CONNECTIONS
The HD-8 can be controlled by external RS232 drivers. Connect a computer,
terminal, or other RS232 control device to the female DB9 connector on the right
side of the rear panel. The HD-8 is wired as a data terminal; that is, data out of the
HD-8 is on pin 2, data in is on pin 3, and pin 5 is common (ground).
A direct connection from a PC compatible COM port normally works well;
select 9600 baud, 8 bits, no parity, and one or two stop bits. Set the Flow Control to
NONE.
2.8 SETUP AND CONTROL USING THE KNOX HD-8 PROGRAM
This program is intended for use by the installer only. Install the program from
the CD provided into a PC-compatible computer running Windows 98 or better.
Start the KNOX.EXE program by double-clicking on the Knox HD-8 desktop
icon or on the name in Windows Explorer. You must select the correct COM port
before attempting to communicate with the HD-8. Click on the SET COMM PORT
button in the lower center, or pull down the Serial Port menu item; select an
available COM port. The baud rate and configuration will be assigned automatically.
FIRST TIME SETUP:
Use this setup procedure when the HD-8 is first installed, or after changing its
internal memory backup battery.
Setting Time and Date: Locate the Time and Date box in the lower right and
check them for accuracy. You can modify the time or date if necessary by using
your computer’s Control Panel. To send the correct time and date to the HD-8,
select EDIT mode in the box on the far left and push the SEND TIME/DA TE button
in the Time and Date box.
Assigning Names to Sources and Destinations: Sources and destinations are
given default names by the program. T o give them more meaningful names, first
select EDIT mode in the box on the far left. Then highlight each of the Destination
Zones on the left and give it a short name (five letters and numbers maximum).
Then highlight and name as many of the video, audio, and IR sources as you wish.
When you have named all the sources and destinations you wish to at this time,
push the WRITE button on the far right side. The new names will be sent to the
HD-8. Note: the default names remain available as an alternate set of names each
time the program is brought up.
Setting the LCD Banner Lines: Both lines on the LCD can be personalized
by the installer; for example, you might want the first line to identify the
homeowners, and the second line to give them a number to call for service.

the On-Screen display show the customized names assigned to the Sources and
Destinations, or to have the default set of names show. Choose Names in the OnScreen Display box in the lower left-center to have the custom names appear;
choose Numbers to have the default numbers appear.
SECTION 3. OPERATION
3.1 INTRODUCTION
This section explains in detail the operation of the HD-8 using either the front
panel pushbutton switches, the IR remote control, or the RS232 port.
3.2 CONNECTIONS
Connect audio, video, and IR sources as described in sections 2.4, 2.5, and 2.6.
There is no requirement that all inputs or outputs be used or terminated, but be sure
that all outputs which are used are properly terminated.
An output may be looped back to an unused input via short cables for the
purpose of adding a delay, but be aware that if an output is then routed to that same
input, an illegal condition will exist and the output will oscillate at frequencies
which could spill over onto other crosspoints.
3.3 CONTROL VIA THE FRONT PANEL SWITCHES
NOTE: ZONE LOCK: Zone Lock allows for one-button operation of the HD-8. If
Zone Lock is ON the LED in the lower center of the front panel will be lighted and the
selected ZONE will appear in the display window. If Zone Lock is OFF the light will be
dark. To turn Zone Lock on, press the FUNCTION button in (lower right corner) and
push the 1 button; then select the zone to lock to (usually the local zone, ZONE 8) by
pushing one of the buttons 1-8. To unlock a zone, just press the FUNCTION button
and push the 1 button.
POWER: The front panel power button has three-levels of operation: ON,
DISPLAY OFF, and OFF. However, the crosspoint connections are held as long as
power is being received by the HD-8. If power is lost, the previous crosspoint
conditions will return after power is restored. Generally it is best to have the displays
ON while controlling the HD-8.
