GENERAL INFORMATION

Introduction:

The RGBHV Video with Stereo Audio Fiber Optic Transmission System (AC1020A - V/A System) 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-free transmissions 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 in the AC1021A-XMIT transmitter is a solid- state 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.

installation

Installation Procedure:

The AC1020A fiber optic transmission system for RGBHV with Stereo Audio is de- livered ready for immediate use. There are indicator LEDs on the units for monitoring purposes. The following instructions describe the typical installation procedure and the function of the LED indicators.

1.Connect the video source to the video input HD-15F connector on the transmitter unit.

2.Connect the video output on the receiver unit to the HD-15F connector.

3.Connect the fiber optic cable between the transmitter and receiver unit.
