DANGER! The transmitting element in the Pure Digital Fiberlink 7220 transmit-
ter unit contains a solid state Laser Diode located within the optical connector.
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 INSTRUCTIONS
Installation Procedure:
The Pure Digital Fiberlink
®
7220 Series transmission systems are
ready for immediate use. There are indicator LEDs on the units for moni-
toring purposes. The following instructions describe the typical instal-
lation 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 two Pure Digital Fiberlink
units.
4. Connect the audio input signals to the transmitter stereo jack and the
audio output to the receiver stereo jack.

TRANSMITTER and RECEIVER:
Power:
ON: (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 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.
Alarm:
ON: Loss of video (rack card only)
RECEIVER:
Video:
OFF: Indicates no video detected over fiber and, as a result,
no video present on the 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 fiber and, as a result, video present on the output.
provides an output to drive a model 6020 Alarm Sensing Module which
provides an audible tone and activates a set of contacts for external
signaling purposes.
The status of the LEDs are as follows:
