Installation / Operation Instructions
IR Remote Learning Function
1. Press and hold the power switch for 4 seconds. The power may be in the off or on position. The SW204HD
will enter the learning mode and Output 1, LED 1 will flash.
To learn a command:
2. Using any existing handheld remote (Some Philips models may not work), press a button that you want to
assign to the currently flashing LED channel. The SW204HD will move to the next position and wait for you
to press the next remote button. (You may bypass any selection by pressing either Output Select button on
the SW204HD. Therefore, one or more commands can be changed without disturbing existing commands.)
3. When all eight of the individual channels have been programmed, all 4 of the Output 1 LEDs will begin to
flash. The next button pressed on the users remote control will be programmed to perform the channel
advance function just like the Output Select button on the front of the SW204HD. The last 4 LEDs will flash
next to allow the Output 2 channel advance function to be programmed.
4. At last all 8 of the LEDs will flash, allowing the user to program the power on/off function to the next button
pressed on the users’ remote control. Learning is now complete.
The SW104HD includes a remote control to select the desired device or turn power on or off. In addition to
the front panel controls and the IR remote, the SW204HD may be controlled over USB or RS-232 with a PC
using a software application included on the CD or downloaded from “www.celabs.net”.

Appendix A
The SW204HD Controller Application - CE LABS, inc
The SW204HD Controller application controls and monitors the SW204HD video/audio switch. The SW204HD
is a 4 input, 2 Output switch. Each input and output consists of component video and right/left/digital audio.
The SW204HD Controller application runs on a Windows XP/Vista computer and connects to the SW204HD
either through USB or RS232 ports. The SW204HD Controller application provides ability to toggle power and
switch inputs on the SW204HD from a computer. In addition to controlling the switch, a straight forward
graphical representation of the switch connections is provided. Finally, the inputs and outputs can be renamed
making switch connections simple to determine.
Getting Started
The SW20HD Controller must first connect to a SW204HD unit. The SW204 supports RS232 or USB
communications.
Step 1: Setup the SW204HD
Attach a RS232 cable or USB cable between the SW204HD and the computer. Set the switch on the back of
the SW204HD unit to RS232 or USB to match the cable used. Insure the power adapter is connected to the
SW204HD.
If using USB for first time with the SW204HD, you may want to read the notes at end of this help
screen on using USB.
Step 2: Start the SW204HD Controller Application
If not all ready running, start the SW204HD Controller application. The application can be started from the
Start Menu under CE Labs.
Step 3: Connecting to the SW204HD
If you know the computer COM port you that is attached to the SW204HD, then select that COM port in the
selection box and click on Connect.
If you are not sure of the COM port, you can click on Auto
Connect.
When first started, The SW204HD is not connected as indicated in upper left
hand corner.
After clicking Connect or Auto Connect, The SW20HD unit should now be connected as indicated in upper left
hand corner.
If the unit fails to connect, try a different COM port or attempt Auto Connect if not
tried already. Also, check the cable between the computer and SW204HD and
make sure the power adapter is properly attached to the SW204HD switch.
After successful connection, the SW204HD can then be controlled and monitored.
To disconnect, click on the disconnect button.

Controlling and Monitoring the SW204HD
Once connected, the SW204HD may be controlled using the Power, and Select Buttons. The current Power
status of the SW204HD is shown next to the Connect status.
If power is off, then the following status appears.
To toggle power, simply click the power button. Before any other controls can be used the Power must be ON.
When power is ON, then the Output Select buttons can be used to change the switch settings. The numbered
input indicators may also be clicked to change switch settings.
Click the buttons to perform the desired operation.
You may also click the numbered indicators to change directly to an input.
The Power Button toggles the power on the SW204HD.
The Output Select Buttons set the next input for the output. That is, if Output Select 1 is clicked, the switch will
step to the next Input in order for output 1. When the input is on 4, it will step to 1.
When power is off, the controls will not function and the numbered input indicators will be grayed –out.

The Graphical Status Display
The lower part of the screen of the SW204 Controller shows the switch status in a graphical format.
Below, it can be quickly seen that Output 2 is connected to Input 2 and Output1 is connected to Input 4. Note
that it is possible for both outputs to be connected to the same input.
Re-Naming the Inputs and Outputs
A special feature of the SW204HD Controller application is the ability for the user to rename inputs and outputs.
Simply by clicking on the output or input label in the graphical status portion of the screen, the user may edit
the label text.
The labels may be edited at any time. The new labels are automatically saved.
For example, click on
A cursor will appear and “Input 1” can be edited to something else like “DVD”.

Example status with new labels
When the power is off, no connections are made and the status will be grayed- out as below.
Notes on using USB
When a USB cable is first plugged in between a Windows XP/Vista computer and the SW204HD, a “Found
New Hardware” message could pop up. This indicates that the USB serial driver for the SW204HD needs to be
installed. Simply, follow the Windows directions for installing the needed driver. Once complete, the SW204HD
should work fine with USB.
If the USB cable is plugged into the computer or the SW204HD after the SW204HD Controller is started, the
COM port associated with the USB will not be available in the selection box. Simply use Auto Connect in this
case. Auto Connect should find the correct COM port and connect to the SW204HD.
