3.3. Pre-Installation Checklist

The Component Video Hub provides a centralized component video distribution center via copper twisted pair cabling.

1. The Component Video Hub is typically installed in a remote telecom room and is connected to the component video source and display devices via Cat5 twisted pair. MuxLab component video baluns are installed at each component video devices to support the connection to the hub via Cat5 cable.
2. For optimum performance and to support HDTV (720p, 1080i/p) resolution, the Component Video Hub is used in conjunction with MuxLab's passive Component Video Baluns (p/ns 500050, 500051, 500052, 500053).
3. The Component Video Hub will also work with third party vendor baluns, providing the pin configuration and signal polarity are compatible. However, performance specifications may be affected.

3.4. Physical Installation

The Component Video Hub has two models; 8-port desktop (500250, 500251) and 16-port rack-mount (500252, 500253).

1. If the 8-port hub is being installed on a desk, select the final destination for the product and install the unit on a desk or shelf as shown below.

3.5. Installation Procedure

The Component Video Hub is available in 8-port (500250, 500251) and 16-port (500252, 500253) versions. In order to install the product, please follow the steps below:

1. Install the Component Video Hub in its final location by performing steps 1 or 2 listed in the previous section.

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

3. If audio will be transmitted along with video, set the hub to digital or analog audio by sliding the switch on the rear panel to the appropriate position as shown in the diagram below. The factory default setting is "analog audio".

Analog Audio Digital Audio

1. In order to distribute component video (YPbPr/RGB) and audio (optional), one (1) Component Video Balun must be connected at the component video source and at each component video display. To install the baluns, perform the following steps (5, 6 and 7):

2. Identify the pin configuration of the baluns. Three (3) twisted pairs are required for video and one (1) twisted pair is required for optional digital audio. The pin configuration follows the EIA/TIA 568A/B standard. The Component Video Baluns are reverse polarity sensitive. Please ensure that wiring is straight-through (Ring to Ring, Tip to Tip).

1. Connect a Component Video/Digital Audio Balun (500050, 500051) or Component Video/Analog Audio Balun (500052, 500053) to each component video display.

2. Complete the connection between the component video source and the Component Video Hub using standard straight-thru Cat5 twisted pair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensure that there are no split pairs or taps.

3. Complete the connection between the hub and each component video display using standard straight-thru Cat5 twisted pair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensure that there are no split pairs or taps.

4. If audio is to be connected (optional), connect an RCA lead between each Component Video Balun and the audio equipment at both ends.

5. Connect the external 12VDC power supply to the hub and plug the power supply into an AC power outlet. If power is present, then the green power LED will be ON.

6. Power-on the component video equipment. Check the image quality and refer to the troubleshooting table below if the image quality is unsatisfactory.
