Installation

Preparing Your Site

1. Determine where the local video source (i.e. computer, Blu-ray Player) will be located and set up the device.
2. Determine where the remote display will be located and place/ mount the display appropriately.

NOTE: This HDMI® extender kit features Power over cable, allowing both the Transmitter and Receiver to be powered from a single power source that can be connected at either end of the connection. Please ensure that either the Transmitter or the Receiver Unit is situated near an available AC electrical outlet. Make sure all devices are turned off before beginning installation.

Hardware Installation

• Install the Transmitter Unit
  • Position the Transmitter Unit near the video source (i.e. Computer, Blu-ray Player).
  • Connect an HDMI® cable from the video source device (i.e. computer, Blu-ray Player) to the “HDMI® IN” on the Transmitter Unit.
  • (Optional) If you’ve chosen to power the kit from the Transmitter side, connect the provided power supply.
• Install RJ45 terminated Cat5e/6 Ethernet Cables
  • Connect an RJ45 terminated Cat5e/6 Ethernet cable (not included) to the LINK OUT A (RJ-45 connector) on the Transmitter unit.
  • Connect another RJ45 terminated Cat5e/6 Ethernet cable (not included) to the LINK OUT B (RJ-45 connector) on the Transmitter unit.

NOTE: If you are using surface cabling, ensure you have enough Category 5e unshielded twisted pair (UTP) network cabling to connect the Host Unit to the Remote Unit’s location, and that each end is terminated with a RJ45 connector. The cabling should not go through any networking equipment (i.e. router, switch).

OR

If you are using premises cabling, ensure that the Category 5 unshielded twisted pair (UTP) network cabling between the Host Unit and the Remote Unit has been properly terminated in a wall outlet in each location and there is a patch cable long enough to connect the Remote Unit and the Host Unit to their respective outlets. The cabling should not go through any networking equipment (i.e. router, switch).

• Connect the other end of the Cat5e/6 cable (from LINK OUT A) to the LINK IN A (RJ-45 connector) on the Receiver Unit.
• Connect the other end of the Cat5e/6 cable (from LINK OUT B) to the LINK IN B (RJ-45 connector) on the Receiver Unit.

NOTE: If using Cat6 cables, extension distance is limited to 40m (130 ft)

• Install Receiver Unit
  • Position the Receiver Unit near the video display (i.e. television, projector).
  • Connect the video source to the HDMI® OUT on the Receiver Unit using an HDMI® cable.
  • (Optional) If you’ve chosen to power the kit from the Receiver side, connect the provided power supply.
• Your source video image will now appear on the remote video display.

Operation

Video Adjustment (Receiver Unit Only)

This function allows adjustments in the sharpness of the video image for better clarity. If necessary, adjust the EQ Selector at the Receiver Unit to compensate for cable length. Turn the EQ Selector one notch at one time and wait for 10~12 sec. For HDMI cable length (Rx-to-monitor) less than 8 meters, the selector position is around 0~7 (depending on video resolution). For HDMI cable length (Rx-to-monitor) greater than 8 meters, the selector position is around 8, 9, A~F (depending on video resolution). For example, if using a 1.8M (or 3.0M) HDMI cable, a CAT5 cable, and a display with a resolution of Full HD (1920 x 1080), you may adjust the video according to its CAT5 cable length as follows.

The following is the test result while using different types of CATx cables

Cable Type                                     Resolution| Cable Length (max.)
---|---
1080i| 50M
1080p| 40M
CAT5                                                 1080i| 50M
(solid)                                                1080p| 20M
CAT5                                                 1080i| 40M
(stranded)                                           1080p| 16M

EDID Configuration

If you are experiencing poor resolution or inconsistent audio or video output, you can specify EDID settings or copy EDID settings using the EDID button.

Auto EDID Configuration

The Transmitter can automatically copy EDID settings from the connected display. In order for this function to work both Link Out A and Link Out B Ports on the Transmitter need to be connected to the Link In A and Link In B Ports of the Receiver via Cat5e/Cat6 Cables.

1. Connect a Cat5e/Cat6 Cable (sold separately) to the Link Out A port on the Transmitter.
2. Connect the other end of the Cat5e/Cat6 Cable to the Link In A Port on the Receiver.
3. Connect a Cat5e/Cat6 Cable to the Link Out B Port on the Transmitter.
4. Connect the other end of the Cat5e/Cat6 Cable to the Link In B Port on the Receiver.
5. Connect an HDMI Cable to the Video Out Port on the Receiver.
6. Connect the other end of the HDMI Cable to the HDMI port on the Display.

Manual EDID Configuration (EDID Copy / EDID Ghost)

1. Connect a Cat5e/Cat6 Cable (sold separately) to the Link Out A port on the Transmitter.
2. Connect the other end of the Cat5e/Cat6 Cable to the Link In A Port on the Receiver.
3. Connect the Universal Power Adapter to the Power Jack on either the Transmitter or Receiver and the other end into a power supply to power the unit.
4. Connect an HDMI Cable to the Video Out Port on the Receiver.
5. Connect the other end of the HDMI Cable to the HDMI port on the Display.
6. On the Transmitter, press the EDID Copy button. Release the EDID Copy button once the LED Indicator flashes green. The LED Indicator will flash green, red, and blue, indicating that the copy was successful.
7. If the LED Indicator flashes red:
   • The display may not be properly connected to the Video Out Port on the Receiver.
   • The display may not be powered On.
   • The display’s EDID data may not be compatible with the Receiver. Connect a different display.
8. Correct the issue and repeat Steps 3 to 4 until the LED flashes green & red and then blue.

EDID Factory Default Setting

To avoid confusion about which EDID information has been copied or for more purposes, this function enables resetting the state to factory default.

1. Follow the instructions in the Hardware Installation section to connect the Transmitter to the Receiver.
2. On the Transmitter, press the EDID Copy button. Release the EDID Copy button once the LED Indicator flashes red. The LED Indicator will flash green and red indicating that the EDID settings were reset to the factory default settings.

DDC Pass Mode

Press the button for more than 15 sec. and release it right after the LED flashes green. The LED lights are blue indicating the setting successfully. To exit this mode, follow the “EDID Factory Default Setting” steps.
