Class B Digital Device. This equipment has been tested and found to comply with the

limits for a Class B computing device pursuant to Part 15 of the FCC Rules. These

limits are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications. However,

there is no guarantee that interference will not occur in a particular installation. If

this equipment does cause harmful interference to radio or telephone reception,

which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

• Consult an experienced radio/TV technician for help.

Caution: Changes or modifications not expressly approved by the party responsible

for compliance could void the user’s authority to operate the equipment.

To meet FCC requirements, shielded cables are required to connect this device to

other Class B certified devices.

This digital apparatus does not exceed the Class B limits for radio noise emission from digital

apparatus set out in the Radio Interference Regulation of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites

applicables aux appareils numériques de classe B prescrites dans le Règlement sur le brouillage

radioélectrique publié par Industrie Canada.

CHAPTER 2: Introduction

2. Introduction

With the RGB Video Balun, you can transmit composite baseband red/green/blue

video signals across Category 3 or better unshielded twisted-pair (UTP) cable,

which is already wired into most commercial sites. Use pairs of Baluns to transmit

RGB video: The Balun near the video source takes the three composite baseband

video signals from 75-ohm coaxial cable, converts them, and transmits them over

UTP cable to the other Balun, which puts them back on coax and sends them to

their destination.

Connect the RGB Video Balun to a site’s structured cabling through a modular

wall jack in the work area. Each Balun has three BNC connectors at one end and

an RJ-45 jack at the other end.

The Video Balun is designed for use with RGB monitors, such as those often

deployed in banks, investment houses, and stock-exchange trading floors.

3. Installation

To install a pair of RGB Video Baluns, take these steps:

CAUTION!

D n t attempt t pen the h using. There are n user-serviceable parts

inside the RGB Vide Balun. Opening the unit will v id y ur warranty.

1. Make sure that the video-destination device is not too far away from the video-

source device (refer to the Maximum Distance specification in Chapter 1). If

the destination device is beyond the reach of the source Balun, the video

signal the device receives will be weak or nonexistent.

2. Follow the manufacturer’s instructions for turning off power to the video

equipment you will be attaching, and disconnecting that equipment from AC

power and from all other devices.

3. Make certain that the telecommunications outlets and cross-connects to

which you will connect the Baluns are configured properly and are labeled so

that the circuit can be identified.

CAUTION!

D not c nnect the RGB Vide Balun t a telec mmunicati n utlet

wired t unrelated equipment. Making such a c nnecti n may damage

the equipment and/ r the Balun. Make sure that all wiring is straight-

thr ugh-pinned.

4. Verify that the twisted-pair circuit you want to use is not already being used

for other LAN or telephone equipment.

5. Optional: Each Balun comes with VELCRO®mounting pads. To mount a

Balun to a surface, first make sure that that surface is free of dust, oil, etc., so

the VELCRO will adhere to it. Then peel off the adhesive backing, attach one

side of the pads to the Balun, and attach the other side to the surface.

CAUTION!

D not m unt the Balun ver equipment-ventilati n penings. D ing s

might damage the Balun r cause the equipment t verheat.

6. Attach each Balun to its associated RGB device with a set of three cables,

preferably the three included with the Balun. (If you use other cables, they

must have BNC male connectors on the Balun end.)

CHAPTER 3: Installation

7. Connect one end of a UTP cable to each Balun’s RJ-45 modular jack, as

shown in Figure 3-1. These cables must carry at least three wire pairs, and

these wires must be pinned to RJ-45 Pins 1, 2, 3, 6, 7, and 8.

Figure 3-1. The Balun and its connectors.

8. Plug the other end of each UTP cable into the appropriate video wall outlet

or patch panel. When this is done, a complete cabling circuit should run

between the two baluns, as shown in Figure 3-2 below.

Figure 3-2. Two Baluns cabled together.

9. Reconnect and power up the video equipment.

Your RGB Video Balun system should be ready for continuous operation.
