3.5. Installation Procedure

In order to install the product, please follow the steps below:

1. Place the HDMI 1x4 Distribution Hub in its final location.

2. Ensure that the power is turned off on the HDMI source and displays.

3. In order to distribute the HDMI, one (1) HDMI/IR Receiver Balun (500407) must be connected at each HDMI display. To install the Baluns, complete Steps 4, 5, and 6.

4. Identify the pin configuration of the Baluns. Two (2) Cat 5e/6 UTP/STP cables are required for each HDMI connection. The pin configuration follows the EIA/TIA 568A/B standard. The HDMI/IR Receiver Balun is reverse-polarity sensitive. Please ensure that the wiring is straight-through (Ring to Ring, Tip to Tip), and that the two HDMI twisted pair links are not crossed.

5. Using an HDMI cable (not supplied), plug the HDMI source to the HDMI input of the HDMI 1x4 Distribution Hub. If the Cat 5e/6 input is used, one (1) HDMI/IR Transmitter Balun (500406) must be connected to the HDMI source, and two (2) Cat 5e/6 UTP/STP cables are required. The HDMI/IR Transmitter Balun is reverse-polarity sensitive. Please ensure that wiring is straight-through (Ring to

e 11

Pag

Ring, Tip to Tip), and that the two HDMI twisted pair links are not crossed.

6. Using an HDMI cable (not supplied), connect an HDMI/IR Receiver Balun (500407) to each HDMI display.

7. Complete the connection between the Hub and each HDMI display using standard straight-thru Cat 5e/6 UTP/STP cables and connecting hardware, terminated on RJ45 plugs at both ends. Ensure that there are no split pairs or taps.

8. Select the desired EDID setting using the rotary dial.

9. Power up the Baluns and HDMI equipment first.

10. Connect the external 12VDC power supply to the Hub and plug the power supply into an AC power outlet. If power is present, the blue power LED will be ON.

11. Ensure that the source and appropriate display LEDs are ON. Images should appear on the displays within 10 seconds. Check the image quality and refer to the troubleshooting table in Section 4 if image quality is unsatisfactory.

3.6. EDID

EDID (Extended Display Identification Data) is data that describes the capablities of a display device to a source device. The EDID includes the resolutions and modes supported by the display device.

In the context of MuxLab’s HDMI 1x4 Distribution Hub, the source device consists of the HDMI source (typically a DVD player), and the display device consists of the remote & local displays (typically TVs), to which the Distribution Hub is connected.

The user sets the EDID via a four-position selector located on the back panel of the Distribution Hub (Figure 6). Each position communicates a different EDID setting to the HDMI source, establishing the resolution and mode at which the HDMI source will send data to the display devices.

Figure 6: EDID Selector

EDID settings are described in detail on the following two pages:

e 14

Pag

Position 1: HDMI 1.2

 HDMI 1.2 Profile.  Maximum resolution: 1080i.  Supported color depth: 8 bits per color.  Setting is most compatible with all display devices that

support HDMI 1.2 or better.

 Disables Deep Color (affects all display devices).  Prevents an HDMI source from auto-negotiating a

resolution higher than 1080i.

 Supports most display devices on the market.

Position 2: HDMI 1.3

 HDMI 1.3 Profile.  Maximum resolution: 1080p.  Supported color depth: 8, 10, or 12 bits per color.  HDMI source will auto-negotiate to resolution of 1080p.  Display devices that do not support 1080p will not work

at this resolution.

Position 3: Copy EDID

 Copies the EDID setting from the first display device in

the chain.

 Port priority is UTP/STP Outputs first (1, 2, 3, 4) THEN

Local Monitor Output.

 The user must place the lowest resolution display device

on the copy port. All other displays will follow.

 As with Position 1, this does not prevent the user from

manually selecting a resolution which a display device does not support.

 For the copy to take place, a display device must be

plugged in when the Distribution Hub is powered up. Failure to do so will result in no display device working.

e 15

Pag

Position 4: Adaptive EDID

 Analyzes the EDIDs of all the display devices in the

chain, and generates an EDID that represents them all.

 Allows dynamic changes to the chain. However adding

a less robust display device to the chain will make other display devices glitch for a fraction of a second as settings are downgraded.

In short, Positions 1 and 2 establish generic EDID settings that never change, regardless of the display devices being used. Positions 3 and 4 establish EDID settings that depend on the display devices, and are typically more optimized for such devices.

If the user selects an EDID setting which a given display device does not support, that device will not function.

EDID resolutions are only taken into account when an HDMI source is auto-negotiating resolutions.

Color Depth

The color depth of a display device refers to the ability of its constituant pixels to display color. This ability is typically expressed in terms of bits: The greater the number of bits, the greater the number of different colors that a pixel can display. An 8-bit color depth (per color channel) is standard.

The term Deep Color refers to a color depth of 30 bits or higher (10 bits per color channel or higher in the RGB model). Consequently, a display device with a color depth of 30 bits or higher is known as a Deep Color display.

e 16

Pag

EDID Settings and Color Depth

By setting the EDID selector to Position 1 (or by setting the EDID selector to Position 3 and placing a non-Deep Color display device on the copy port), the user disables Deep Color. This will allow for greater distances via UTP/STP cables.

Regardless of color depth mode, a display device will always receive the highest color depth signal it can support. This means that if the source delivers a color signal of 10 bits per color or higher, a Deep Color display will receive the signal unchanged, while a nonDeep Color display will receive a normal 8-bit signal. This is transparent to the user.

e 17

Pag

3.7. Cascadability

HDMI 1x4 Distribution Hubs may be cascaded in order to send an HDMI signal to more than four (4) displays. In fact by using the Local Monitor port of the Distribution Hub, in theory an unlimited number of Hubs may be connected in a daisy-chain configuration. This is possible because a clean video signal is regenerated at each Distribution Hub.

In more practical terms, the Distribution Hubs would typically be connected in a tree configuration:

Regardless of the configuration chosen, the EDID selector on each Hub should be set to Position 1 or 2 in order to avoid conflicts.

NOTE: When cascading via UTP cables, cable lengths must be kept within 75% of maximum allowable distance (see Technical Specifications, page 6).

• Verify cable lengths

• Use STP cables

• Set EDID selector to Position 1 or 2

• If cascading multiple hubs, ensure that UTP cable lengths are 25% less than maximum allowable

• Only one source may be connected to the Distribution Hub at any one time. MuxLab does not support switching between input ports

• Ensure that all cable lengths are within specification

• If EDID selector is in Position 3, ensure that lowest resolution display device is connected to the Copy Port.

• Set EDID selector to Position 1 or 2

• Ensure that the HDMI source is outputting a signal compatible with all the display devices (try 1080i or 480p). NOTE: The EDID selector does not prevent the user from choosing an incompatible mode
