RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio communication. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be necessary to correct the interference.

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par le ministère des Communications du Canada.

OPERATING POINTERS & TROUBLESHOOTING

Optical Fiber:

The RGBHVwith StereoAudio fiber optic transmission system is designed to operate with most multimode (MM) and single mode (SM) optical fibers.

Remember to check the attenuation and bandwidth of the fiber optic cable. The system will only operate properly if these specifications fall within the range of the system’s loss budget.

Troubleshooting:

Multimode fiber optic cable contains an optical fiber with a light carrying “core” that is only .0025 inches (62.5 microns) in diameter. Single mode fiber optic cable has an even smaller “core”, only 00032 to .0004 inches (8-10microns). This is smaller than a human hair! Therefore, any minute particles of dirt or dust can easily block the fiber from accepting or radiating light. To prevent this from happening, always use the provided dust caps whenever optical connectors are exposed to air. It is also a good idea to gently clean the tip of an optical connector with alint-freecloth moistened with alcohol whenever dust is suspected.

The status of the VIDEO and AUDIO indicator LEDs should provide the first clue as to the origin of an operational failure. If these are off, it usually means that the fiber is broken or has too much attenuation. Next, be certain that the input and output signal connections are correct.

If, after reviewing the above possibilities, the system is still not operating, please contact the Black Box Tech Support for further assistance

Maintenance:

The only maintenance of the AC1020A system that can be provided by the user is to ascertain that the optical connectors are free of dust or dirt that could interfere with light transmission and that electrical connections are secure and accurate. DANGER!Always disconnect the transmitter power before removing the optical fiber from the unit! For assistance with all other repairs, please contact Black Box technical support.

Indicator LEDs:

The transmitter and receiver units in the A1020A system each have three integral indicator LEDs that are used to monitor the state of the unit. Their status is as follows:

TRANSMITTER and RECEIVER:

Power: (Green) Indicates that correct power has been applied.

TRANSMITTER:

Video: OFF: Indicates no video detected on the input.

BLINKING GREEN: Indicates either H or V sync detected at the input but not on both.

STEADY GREEN: Indicates both H and V sync detected on the input.

Audio: OFF: Indicates no audio detected on the transmitter unit.

BLINKING: Indicates audio detected on the transmitter unit.

RECEIVER:

Video: OFF: Indicates no video detected over fiber and, as a result, no video present on output.

BLINKING GREEN: Indicates either H or V sync detected over the fiber but not both.

STEADY GREEN: Indicates both H and V sync detected over the fiber and, as a result, video present on the output.

Audio: OFF: Indicates no audio detected over fiber and, as a result, no active audio detected by the receiver unit.

BLINKING: Indicates audio detected over fiber and, as a result, active audio detected by the receiver unit.

GENERAL INFORMATION

Introduction:

The RGBHVVideo with StereoAudio Fiber Optic Transmission System (AC1020A- V/ASystem) is a transmitter/receiver pair that transmits a single channel of RGBHV and two audio channels over one single mode or multimode fiber.

The system’s all digital encoding delivers noise-freetransmissions that retain all of their initial parameters, regardless of fiber optic cable attenuation. System operation may be easily monitored using integral indicator LEDs on each unit that continuously signify the presence of baseband video and audio signals.

CAUTION! The transmitting element intheAC1021A-XMITtransmitteris a solidstate Laser Diode located in the optical connector on the unit. This device emits invisible infrared electromagnetic radiation which can be harmful to human eyes. The radiation from this optical connector, if viewed at close range without a fiber optic cable connected to the optical connector, may be of sufficient intensity to cause instantaneous damage to the retina of the eye. Direct viewing of this radiation should be avoided at all times.
