Installation

• Before installation, power off all devices that will be connected to this system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and machines that are likely to generate electrical noise.

NOTE: If no screen displays, follow these steps:

1. Make sure the device cables are correctly and firmly attached.
2. Set your display device's input source as DVI.
3. Check the PC BIOS configuration for the video output settings.
4. Connect your computer to the display DIRECTLY to check if the video signal gets through.

Installation Steps

1. Use a video cable (DVI) to connect the display to the video output port on the back of the switch. Plug a set of audio jacks from the speaker to the switch's speaker port.
2. Use a video cable (DVI) to connect the source device to the video input port on the switch. Use an audio cable to connect the speaker port from the input side of the switch to the corresponding output port on the source device.
3. Plug the power supply into the switch and power on the switch.
4. Turn on the display (monitor, projector, or TV) and then power on the source device(s).
5. If necessary, apply EDID Copy process to the unit.

NOTE: When each video source is powered on, make sure it has a display pointing to it for EDID communication. If a source does not have a display pointing to it, a video image might not display.

Operation

LED Indicator
The Power LED turns green when the video switch is powered on. When a video port is selected, its corresponding Port LED turns yellow.

Push Button
Press the corresponding button to select a port.

EDID Setting
In some cases, display problems may occur because of incorrect Extended Display Identification (EDID) communication between the display monitor and the unit. This function allows the system either to read the necessary EDID information from the unit, or to copy EDID from EDID-compliant displays.

Default Setting
To reset to the default EDID:

Step 1: Press and hold the "EDID Copy" button on the unit and release the button RIGHT AFTER the Power LED flashes red (6–7 seconds).

Step 2: The LED lights steady red and green indicating that the EDID default setting is completed.

Copy (New) Monitor EDID
When using a monitor (EDID-compliant) for display, the unit's EDID Copy function will enable EDID communication between the monitor and the unit for optimal video quality. Follow these steps:

Step 1: Power on the unit.

Step 2: Connect the EDID-compliant monitor to the switch and power on the monitor.

Step 3: Press the "EDID Copy" button for 3–5 seconds, and release the button RIGHT AFTER the Power LED flashes green.

Step 4: The Power LED flashes red and green alternately, then lights green indicating that the copy is successful.

NOTE: If the Power LED flashes red, the reason could be:

1. The monitor is not connected.
2. The monitor is not powered on.
3. The EDID data of the monitor is not applicable

IR Remote Control

Figure 5-1. Remote control.

The remote control operates within a 1.5-ft. (5-m) range of the DVI switch. To select a source device with a remote control, press the number button (1–8) to directly switch to the corresponding port.

NOTES:

1. Remove the battery protector on the remote control before operation.
2. On the remote control, only buttons 1–8 are activated. The rest of the buttons are reserved for other models.

Serial Control

The DVI and audio switches' built in serial interface enables users to control the switch via a PC, serial controller devices, or home theater system. The controller's serial port should be configured as shown in Table 6-1.

Table 6-1. Serial parameters settings.

To select a source device via serial interface, select the number that corresponds to the port. For example, send "1" to switch to Port 1.
