Important! 4K (UHD) signals are sensitive to cable quality and installation technique. It is recommended to
use CAT6a/7 solid core cables for best results.
Note: For cable distances see the specifications on page 29
Connector
Connector type and size is very important to ensure extenders work correctly. Please match the
cable type with the correct RJ45 connector.
CAT5e and CAT 6 cables should use only CAT5e RJ45 connectors
CAT6a cables should use only CAT6a connectors
CAT7 cables should use only CAT7 connectors
Using the wrong size of connectors may result in interference or loss of signal.
Important! “EZ RJ45 connectors” are not recommended with HDBaseT extenders. Doing so may result in interference
with audio and video transmission.

Analog Multi-Function Inputs
The CLSO-824 multi-function analog inputs (Input 8) can be used with analog video signal formats
including VGA
input and embedded using the provided captive screw connectors.
Either format can be directly accessed from RS-232, IR, or IP control. It can also be accessed through
the front panel menu.
VGA (m) to BNC and VGA (m) to RCA adaptors can be used to connect sources to this inputs.
VGA
Use a VGA to VGA cable to ensure that the Preferred Resolution DDC is communicated to your
source.
RGBHV
Use a HD-15
switch can be connected here to maintain full function of the analog matrix.
Component
YUV (YPbPr) signal from DVD (or other sources) can be input to the CLSO-824 using the green (Y),
blue (Pb), and red (Pr) connections on a HD-15 (VGA) to 5 BNC breakout cable or with a
VGA -3 RCA adaptor.
(with DDC), RGBHV (without DDC), and component (YUV). Balanced analog audio can be
(VGA) to 5 BNC breakout cable for this format. An existing RGBHV analog matrix
A common application for this type of input would be to connect a RGBHV matrix switcher to the
CLSO-824.

Analog Audio
A captive screw analog audio connector is provided to ensure a more reliable and secure
connection. The captive screw connector supports balanced and unbalanced audio input and
output.
Balanced audio connections use two signal wires and a ground to minimize interference to an audio
signal over longer cable runs. Unbalanced audio connections use two wires for connection with
consumer audio components.

Note: Pin outs may vary, please refer to the audio device’s manual to ensure a correct connection.
Important! When terminating cables, please ensure exposed adjacent wires do not touch. This may result in
a short that can damage connected devices.
