AC1020A/AC1021A-XMIT/ AC1021A-REC
Specications:
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 ber.
The system’s all digital encoding delivers noise-free transmissions that retain all of
their initial parameters, regardless of ber 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 ber
optic cable connected to the optical connector, may be of sufcient intensity to
cause instantaneous damage to the retina of the eye. Direct viewing of this
radiation should be avoided at all times.
Installation Procedure:
The AC1020A ber 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 ber optic cable between the transmitter and receiver unit.
