6. OPERATION CONTROLS AND FUNCTIONS
6.1 Front Panel
CLUX-UCEC
HDMI I /O
1
1
HDMI I/O: Connect to the HDMI/DVI output of your source (i.e.,
DVD player or set-top box) or the input ports of an HDMI/DVi
equipped display using a HDMI or HDMI to DVI adaptor cable.
Note: When connecting to an input source, the other HDMI I/O
must be connected to a display device. You cannot control two
sources or two displays simultaneously.
6.2 Rear Panel
HDMI I /O USB
1 2
1
HDMI I/O: Connect to the HDMI/DVI output of your source (i.e.,
DVD player or set-top box) or the input ports of an HDMI/DVi
equipped display using a HDMI or HDMI to DVI adaptor cable.
Note: When connecting to an input source, the other HDMI I/O
must be connected to a display device. You cannot control two
sources or two displays simultaneously.
2
USB: Connect to a PC/laptop with a mini-USB to USB-A type cable
when control of the source/display devices over RS-232 is required.
Please refer to Section 7 for details. This port provides power for the
device when the connected PC or laptop is turned on. However
when the RS-232 mode is not being used, no power is needed, so it
will bypass the system.

7. SOFTWARE INSTALLATION
7.1 Installing the RS-232 Driver
Insert the provided driver CD into your CD-ROM drive, then execute
the FIDIBUS le. Follow the on screen instructions to complete the
installation.
Note: It is not necessary to install this application if users already have
existing RS-232 software installed on their computer.
7.2 Connecting the Hardware
Once the RS-232 driver is installed connect the device to a PC/Laptop
with a mini-USB to USB-A type cable.
Step 1:
Allow the computer to detect the device by following the “found new
hardware” window that will appear. After the hardware has been
successfully detected conrm the detection in Device Manager.
Once the device is successfully connected to the PC, the connection
will be conrmed by the 'Found New Hardware' notication in the
system tray at the bottom right of the screen, as shown in the following
image.

4
A found new hardware wizard will appear on your PC screen.
Choose “No, not this time” and Click “Next” to continue.
Select "Search for the best Driver in these locations" and then Click
“Browse” and navigate to the “USB TO RS232 SOFTWAVE” folder on the
CD-Rom. Click “Next” to continue.

5
Click the “Continue Anyway” button to continue.
Click the “Finish” button to complete this part of the installation. Now
the PC will show “Found New Hardware” for the USB Serial Port. This
means the device has been detected.

6
The PC will run the Found New Hardware Wizard again, please repeat
the same steps to complete the installation.
Choose “No, not this time” and click the “Next” button to continue.
Choose “Install from a list or specic location (Advanced)" and click
the “Next” button to continue.

7
Select "Search for the best Driver in these locations" and then Click
“Browse” and navigate to the “USB TO RS232 SOFTWAVE” folder on the
CD-Rom. Click “Next” to continue.
Click the “Finish” button and a conrmation message that conrms
the completion of the installation will be displayed in the system as
shown below.

8
Step 2:
Click 'START Menu' button and select Settings/Control panel/
Performance and maintenance/System/System Properties/Hardware/
Device Manager/Ports (COM & LPT)/USB Serial Port (COM)
Note: The COM Port number as this will be required when using the RS-
232 application.
7.3 Using the RS-232 Application
Step 1:
Please insert the included CD and double click the 'CLUX_UCEC_
AP.exe.' to install.

9
When the application launches (see the image below) the user can
select the following features.

RS232 ComPort and Baud Rate Setting: Click 'Connect' to conrm
the transmission setting and connect to the CLUX-UCEC

CEC Commands and Data Setting

CEC Basic Command Buttons
4
EDID Read, Write, Save File and Load File Buttons
5
RS232 ComPort Communication Log Window
6
RS232 ComPort Communication Log Window Control Buttons
Step 2-1:
Select the COM Port (Refer to Step 2 in Section 7.2) and set the UART
BaudRate to 115200 and press the "Connect" button. From this step
onwards users can start to send or receive CEC commands.

10
Step 2-2:
To send the desired CEC command the Transmit button must be
pressed in order for the command to be to executed. For example,
if we are simulating a DVD player sending the “Active Source 1000”
command to a TV based on CEC protocol, there are a few bytes in
“Active Source 1000” command.
1 2 3 4
5
6
1
Data Length: How many bytes need to be sent. The length
includes the CEC Header, CEC OPCode and CEC Data. In this
example is 5 Bytes.

11
2
Data Type: CEC commands.
3
CEC Header: Bit 7~Bit4 is the Source's Logical address. Bit3~Bit0 is
the Sink's Logical address. In this example the DVD player needs to
send a command to the TV but it is not known if the TV is powered
on or not, so we send the broadcast command to all devices by
entering “4F”.
4
OPCode: CEC protocol commands are detailed in Section 9. In this
example for the “Active Source” command enter “82”.
5
Data Bytes: The payload bytes depend on which command is
being used and different commands will have different data bytes.
In this example the “Active Source” command has to identify
which physical address is needed. The address of the port that
connects to the TV is "1000" therefore “10” and “00” need to be
entered.
6
After entering all the necessary bytes press the “Transmit” button to
send the CEC command.
7
Details of transmitted data will be show on the RS-232 COM port
communication log window.
Step 2-3:
There are 3 built-in commonly used CEC Commands designed for
instant CEC execution. Pressing the button will execute the command
and show in the RS232 COM port communication log window.

12
Step 2-4:
Click on the EDID Read button to read EDID settings of the curently
connected device and press the SAVE button to save it it to the
desired location.

13
If the communications log window shows "EDID Read fail", check the
connection to the device and make sure it is well connected and
powered up, then press the button again to re-read the EDID again.
When the EDID has been read successfully, the communications log
window will show "Read complete". Click on the Save File button to
save the EDID in the user’s desire.

14
Click on the Load File button to download the desired EDID le and
click on the write button to select the EDID.
If the communications log window shows "EDID Write Fail", check the
connection to the device and make sure it is well connected and
powered up and also check the EDID le is correct then click on the
"Write" button to try again.
The RS232 COM port communication log window shows a record of all
CEC commands.
The RS232 COM port log window control allows users to adjust the
RS232 log window’s display.
