Installation and Operation
Before permanently securing the unit for final installation,
test for proper operation of the unit and cables in
your system. It is recommended that you leave
enough ventilation space to provide sufficient airflow
and cooling.
An optional HDMI cable clip (included) allows for a
secure connection of HDMI cables to KD-1x8CSK
units and helps prevent intermittent or complete
signal loss due to poor connectivity.
Active Input / Output LED Indicators
›The front LED indicators indicate that a valid HDMIconnection is made between
the KD-1x8CSK unit and each Input / Output.
EDID Control Settings
At times, your HDMI sources and display may not synchronize
properly. This is when EDID* control should be utilized.
KD-1x8CSK Distribution Amps feature an internal
library of default settings that ensure that your HDMI source’s
output is compatible with the display devices.
Please reset the unit by either unplugging and plugging the
HDMI connections, or via a power cycle for the new settings to
take effect.

Hot Plug Control
The KD-1x8CSK allows modifying HPD (Hot Plug
Detection) protocol between source and display.
Modifying HPD protocol will allow overcoming HPD
handshake incompatibility between source and
display. Modifying HPD protocol may also help fix other
problems related to HDMI connectivity. Forcing HPD will
also allow a source to output a signal even if no display is connected/detected.
RS-232 Commands
The KD-HD16x16ProK provides access to all functions when used with an RS-232 control
system.
Connection protocol is as follows:
›Baud Rate = 57600 bits per second
›Data Bits = 8
›Stop Bits = 1
›Parity = None
›Flow Control = None
›Carriage Return: Required
›Line Feed: Required
