Category Cable
For the category cables used in the installation of these products, please be sure to use a 568B
termination as pictured below:
Connector type and size is very important to ensure extenders work correctly. Please use the
matching cable type with the correct RJ45 connector.
CAT5e cables should use only CAT5e RJ45 connectors
CAT6 cables should use only CAT6 connectors
CAT6a cables should use only CAT6a connectors
CAT7 cables should use only CAT7 connectors
Using the wrong size connectors may result in interference causing loss of signal.
Important! “EZ RJ45 connectors” are not recommended with HDBaseT extenders. Doing so may result in interference
with audio and video transmission.
Use the table below to verify the best category cable for the installation.
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.

Analog Multi-Function Inputs
The CLSO-824 multi-function analog inputs (Input 8) can be used with analog video signal formats
including VGA (with DDC), RGBHV (without DDC), and component (YUV). Balanced analog audio can be
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 (VGA) to 5 BNC breakout cable for this format. An existing RGBHV analog matrix
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.
A common application for this type of input would be to connect a RGBHV matrix switcher to the
CLSO-824.
Captive Screw
The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter
while providing a more reliable connection.
Connecting
When connecting the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly (see picture A) the signal will pass,
incorrectly (see picture B) no signal will pass.
The captive screw connectors have
a contact bar that is adjusted to
compress the wire against the top
contact plate. Use the screws at the
top of the connector to compress
the wire against the contact plate.
Clockwise
Counter
Clockwise
Turn the screws clockwise to
raise the contact bar to the

Tip (+)
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.
Important! With unbalanced connections a jumper is needed between ground and negative to reduce noise
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.

A login screen will appear (this is the same log in for admin and general users). For the first log in (and future
admin changes) the username is “root” and password is “Atlona”.
Note: Only the admin password can be changed (see page 15). The username will always remain “root”.
TCP/IP
For convenience, the CLSO-824 comes with DHCP on. This enables the switcher to be connected to
a network without concern for overlapping IP addresses with other devices on the network. If your
network does not support DHCP, this feature may be turned off and the IP address set using RS-
232 commands.
Note: If your system is controlled using IP, it is strongly recommended that you disable DHCP and select an unused IP
address so that your system controller doesn’t lose contact with the switcher.
TCP/IP and WebGUI Setup
Atlona has created an easy to use webGUI for initial setup and later changes to the configuration
of the CLSO-824.
To begin, connect the LAN port of the CLSO-824 to your network. Type the IP address of the
CLSO-824 into the web browser of a PC connected to the same network (as seen below).
To find the switcher IP: Select “Info” on the front panel display or use RS-232 command “IPCFG”.
Important: If any stability issues are experienced, disable any anti-virus or firewall that may interfere with
network communication to the switcher. Once set up is done and the switcher GUI is no
longer being used, the firewall and anti-virus can be re-enabled.

The information is very useful when trouble-shooting your installation. It includes information on the
switcher, connect sources, and outputs.
13

1-408-962-0515
The network set up page will allow the IP information to be changed. When a change is made the
screen will grey and the ability to save or cancel will display at the bottom (see below).
Note: When DHCP is on, the IP address cannot be configured. Turn DHCP off to enable IP configuration.
Note: For a stable connection when using a control system, it is best to set up a static IP. When selecting an IP address,
make certain no other devices on your network are using that IP address.
Login Mode has been added to provide a secure telnet login. Once Login Mode has been turned on
a username and password will be required on all IP connections to the switcher.
Note: Login mode should be in off position when the CLSO is used with control systems that do not support
passwords. If your control system supports password protection, set the login mode to on.
The GUI always requires a password.
Note: The username and password used in IP Login Mode will be the same login information as the webGUI.
Note: Be sure to save all changes before moving to the next page.

From the Config page the admin password can be changed, users added, and the RS-232 ports
to be configured. CLSO-824 system port, the RS-232 I/O ports, and the HDBaseT/Valens ports
can be adjusted individually. RS-232 ports must be configured to match the device to which they
are connected. For example, the system port should match the settings of the control system, the
individual port settings should match the devices connected to them. The CLSO-824 will adjust the
signal from the control system to match the output device.
Note: User information will display for the admin only.
Note: Only the admin password can be changed. The admin username will always remain “root”. If the admin
password is lost the system must be returned to factory settings and setup repeated.

The EDID page provides the option to adjust the EDID of the HDMI and HDBaseT ports, select the
preferred timing of the VGA port, and set the HDCP compliance reporting.
Note: If no audio is being received, try adjusting EDID. If the CLSO does not receive a complete EDID and the HDMI
port will default to DVI (which has no audio).
Note: 2Ch audio EDID is recommended unless the system is being used as an audio pass through.
Note: CLSO-824 protects HDCP encoded content and will not pass HDCP content to a non-HDCP compliant device.
Note: Some devices flag all content as protected when connected to an HDCP compliant display. This prevents what
should be non-protected content from reaching non-compliant devices (e.g. teleconference system) through
the CLSO-824.
Note: When HDCP reporting is non-compliant, only user created content is transmitted. Protected content from all
sources (e.g. Blu-ray, AppleTV, etc.) is blocked.
Note: These functions are also controllable using TCP/IP or RS-232 commands.

Ducking Setup
Note: Proper set up is critical for satisfactory operation. If program levels are too high they can trigger the ducking
process. Microphone ducking uses the audio level from the microphone to decrease the program level so the speaker
may be heard. Setting the microphone volume too high may result in feedback. It is recommended that a handheld
or headset microphone be used with ducking to reduce feedback and maximize the difference between voice and
program levels. Best results are received with the following sequence:
1. Set master volume to 0. (This is 10 db below maximum)
2. Raise appropriate microphone (or line in) volume until just below feedback or adequate volume is reached
(whichever setting is lower). - Master level and amplifier gains may be increased to get appropriate levels
Note: If feedback occurs and volume is not adequate, move the speakers and/or microphone to eliminate feedback.
3. Raise source “sub” volumes to appropiate levels without talking
4. Set attack time to minimize popping, but still fast enough that initial talking sounds are heard.
5. Set release time so that program levels do not increase between sentences. Note: Shorten time so that the
microphone doesn’t interfere with the program.
6. Set the trigger level so that words spoken at a normal level trigger the ducking process Note: Set the trigger level too
sensitive and the program will trigger the ducking. Set too low and the speaker will have to talk very loudly to
trigger ducking. The further right the slider is, the more sensitive the setting.
7. Set program decrease to ensure when ducking is triggered the program level is low enough the speaker can be
heard.
Fine tuning these settings will help achieve the best results.
EQ Output
Settings adjust the equalization for the audio outputs of both analog and embedded audio. The
center frequency for each listed. Nominal position is centered at 0 dB. 5 band EQ adjustment for
HDMI/HDBaseT output ports.

The update page provides an easy way to update switcher firmware.
Download the most current firmware from http://atlona.com/product/AT-UHD-CLSO-824/. Once
the firmware is saved on the computer use the browse button to select the correct file. Press the
update button and a progress bar will display. If a restart of the CLSO-824 is required, the webGUI
will display a prompt.
Setting these parameters will route the HDVS display commands from the HDVS through the CLSO
to the control system/PC at the designated IP address.

System IR is typically used to connect to control system processors. This input is used to control the
CLSO-824.
Note: The IR receiver is optional for the UHD-CLSO-824. The compatible IR receiver (AT-IR-CS-RX) can be purchased
through atlona.com.
The wires of the emitter and receiver have been marked to differentiate the pin outs.
The included IR emitter has two wires: signal and ground. Signal will have a solid line and ground will be
blank. The IR emitter will plug into the IR OUT ports.
There are three wires on the IR receiver (sold separately): signal, ground, and power. Signal has a dotted line,
ground will be blank, and power will have a solid line. The IR receiver will plug into the IR IN ports.

RS-232
Connection
Set Up
To set up the RS-232 terminal (if not using 3rd party software) use the following steps:
1. Connect the CLSO-824 to a PC using a 3 pin to USB cable
2. Go to the Device Manager folder (see picture A)
3. Find the CLSO-824 COM port and right click with a mouse and select properties (see picture B)
Note: If unsure which COM port is the CLSO-824, unplug the cable and plug it back in. It will disappear and
reappear on the COM port list.
4. Under the properties menu select the port settings tab and update the menu to the CLSO-824 default
settings of: Bits per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1 and Flow Control: None.
(see picture C)
Set up is done and any terminal program may be used to control the CLSO-824 now.

RS-232 is often connected through a DB 9-pin to captive screw
connector. The pins will have functions associated with them,
some will be unassigned. Not all pins are used.
Note: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin
5 for ground. On some devices functions of pins 2 and 3 are
reversed.

RS-232 Command for the Output parameters
RS232para
The RS-232 status command will provide feedback for the current parameters for each transmitter/
receiver.
Example: (See example of feedback below)
RS232para
Current RS232 parameter:
- Zone 1 :BaudRate 2400bps, DataBits 0, Parity None, StopBits 1.
- Zone 2 :BaudRate 115200bps, DataBits 0, Parity ODD, StopBits 1.
- Zone 3 :BaudRate 9600bps, DataBits 0, Parity None, StopBits 1.
Note: RS-232 zones 1-10 correspond with the RS-232 ports on the back of the switcher. There are additional zones for
switcher and HDBaseT port pass through.
Zone 11 = HDBaseT input port 1
Zone 12 = HDBaseT input port 2
Zone 13 = HDBaseT input port 3
Zone 14 = HDBaseT output port 1
Zone 15 = HDBaseT output port 2
Note: Default for the switcher is: Baud rate-115200bps, Data length-8bit, Parity-None, Stop Bit-1
Command for Switcher Parameters
CSpara[baudrate,data-length,parity,stop-bit] (data, parity, and stop bit for switcher must be 8,0,1)
For example if you wish to change the baud rate of the switcher to 38400 the command would
look like this: CSpara[38400,8,0,1]
Note: Using the command CSpara will display the current parameters of the switcher
Baud Rate
Zone RS-232 port conifiguration must match the connected device on all parameters including
baud rate, data-length, parity, and stop-bit. These parameters can easily be set using the WebGUI
or following commands through RS-232 or TCP/IP.
The baud rate for the switcher is for switcher control and the transmitter/receiver baud
rate is for control of the RS-232 device in zone. All commands from your control processor are
at the settings for the switcher. The switcher will modify the baud rate and other settings to these
set parameters by zone.
Note: Baud rate options 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400
