HD View 8 Model # KD-RGBDA8
TM
Key Digital® “HD View 8TM” (Model KD-RGBDA8) is an 8-channel VGA Distribution Amplifier. It
is the logical choice for artifact-free distribution of your VGA signals. If you have VGA (RGBHV)
signals from any HDTV multimedia or computer source that you need to feed to up to eight
or more VGA monitors, HD View8 does the job with a bandwidth of 300 MHz on cable runs
up to 300 feet long. All HDTV formats are accepted, like 480i, 480p, 720p, and 1080i/540p;
plus all VESA formats from 640x480 to 1600x1200, with refresh rates from 50 Hz to 80 Hz. An
added benefit is the ability to "daisy-chain" (cascading) multiple units. As long as you terminate at the end of your input cable run, you can readily cascade three or more HD View8 DA’s
and drive a wall of 32 or more VGA monitors, all with crystal-clear clarity.

Mechanical
• Easy to install and integrate
• Cables attach to only one side of the unit
• all video inputs and outputs have DB15 (VGA) female connectors
• The 1U-high unit may be oriented horizontally, or mounted vertically on a wall
• Size: 12 3/16" x 5 1/8" x 1 13/16"
• Weight: 5.5 lbs.
• Enclosure type: Metal (no vents)
• Input Power: External power supply provided, 110-240V AC, 50-60 Hz, 0.9 A
Modes of Operation
The HD View 8TM can be configured for two different modes of operation.
1) 75 Ohm termination mode for stand alone distribution applications or as the terminating
unit at the end of a “daisy-chain” of HD View 8TM units. This is the factory default mode
of operation.
2) High Impedance Loop through mode for “daisy-chaining”. This mode must always be
used when connecting to an additional HD View 8TM unit.
Product Hookup
After unpacking the unit make sure to make all connections before plugging in the power
adapter.
The HD View 8TM will receive virtually any RGBHV signal from a HDTV multimedia or computer source and distribute to VGA based monitors. A typical hookup will consist of a “source”
device which should be hooked up to the DB15 input. Formats accepted include all SD and
HD formats: 480i, 480p, 720p, 1080i/540p and VESA-based PC formats from 640x480 to
1600x1200 with refresh rates 50 Hz to 80 Hz. After hooking up the “Source” device to the
marked input connector, the HD View 8TM will distribute this source up to 8 monitors that are
hooked up to the output DB15 connectors. If you need to distribute the “source” to more
than 8 monitors, you can “daisy-chain” the HD View 8TM to another HD View 8TM by using the
High Impedance loop through mode of operation. When using a daisy chain of HD View 8TMs,
you need to connect the loop-through DB15 connector on the first unit to the DB-15 input
connector of the next unit in the chain. Use also need to set the mode of operation as noted
in the next paragraph of this manual.

HD View 8 Operating Instructions
TM
Setting the Mode of Operation
The HD View 8TM should come from the factory set for single use (terminated or non daisy
chain) operation. The four DIP switches on the side of the unit are used to set the mode of
operation.
Mode One (factory default)
For single use, the switches should all be set in the On (Up) position. (75 Ohm termination
mode)
Mode Two
If you are using the HD View in the daisy chain mode, all switches should be set in the Off
(Down) position (High Impedance Loop mode). Please note that the last unit in the daisy
chain should have its switches set in the On (Up) position (75 Ohm termination mode).
Power Supply Hook Up
After making sure that all hook ups are secure and the settings for the mode of operation is
correct, you need to connect the AC to DC wall power converter. Thus converter has a multipin plug that fits into the connector panel of the HD View 8TM. Please make sure that the orientation of the plug is correct to avoid bending the pins on the plug. After attaching the plug
to the HD View 8TM connect the AC plug into a 115 volt wall outlet.
Operation
Once power has been applied, use a reliable “Source” to test your connections . Since the
HD View 8TM is a powered device it will produce a minimal amount of heat, therefore it is
recommended to leave enough room around the unit to dissipate this heat.
If, after properly connecting all of the devices in the system, the unit fails to properly distribute
the “Source” signal, please check the following:
No power to the unit.
Make sure that the external power supply is properly connected to a standard 115V
household outlet. For added safety and protection it is always recommended to
use a good quality surge protector. Check to make sure that the power connector is
properly inserted into the HD View 8TM.Unplug the adapter from the wall and verify that the
cable is not cut or interrupted anywhere. If the HD View 8TM is still not functioning properly,
please contact Key Digital® technical support hotline at (888) 258-2028 or send an e-mail to
[email protected].
