CAUTION! Some versions of the Pure Digital Fiberlink transmitter unit
contain 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.

Indicator LEDs and Alarm Circuitry

The stand-alone box versions of the Pure Digital Fiberlink 7030 and
7040 Series transmission units have integral LEDs that are used to
monitor the state of the unit. There are two video LEDs on the 7030
units and four video LEDs on the 7040 units. The LEDs are labeled
VID 1, VID 2, VID 3 and VID 4.

The rack card versions of this units have an additional red indicator
LED that lights when an alarm condition exists. The rack card unit also
provides an output to drive a model 6020A Alarm Sensing Module
which provides an audible tone and activates a set of contacts for
external signaling purposes.

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

TRANSMITTER:

Video: OFF: Indicates no video detected on input BNC connector

ON: Indicates video detected on input BNC connector

Alarm: ON: Loss of video (rack card only)

Switch Position Alarm Indication On Off

1 Loss of Signal Enabled Disabled

3 Loss of Video 2 Enabled Disabled
4 Loss of Video 3 Enabled Disabled

(7040 only)

5 Loss of Video 4 Enabled Disabled

Alarm Switch Settings (Receiver; Card Version Only)

Note: “Loss of Link” refers to loss of input signal lock. “Loss of Video”
refers to loss of the respective input video. “Loss of Signal” refers to the
absence of an optical signal.

MAINTENANCE

The Pure Digital Fiberlink 7030 and 7040 Series transmission units
have been manufactured using the latest semiconductor devices and
techniques that electronic technology has to offer. They have been
designed for long, reliable and trouble-free service and are not
normally field repairable. Should difficulty be encountered, Communi­cations Specialties maintains a complete service facility to render
accurate, timely and reliable service of all products.

The only maintenance that can be provided by the user is to
ascertain that optical connectors are free of dust or dirt that could
interfere with light transmission and that electrical connections are
secure and accurate.

All other questions or comments should be directed to our Customer
Service Department. It should be noted that many “problems” can
easily be solved by a simple telephone call.

LIMITED WARRANTY

Communications Specialties, Inc. (CSI) warrants that for a period of
three years after purchase by the Buyer, the Pure Digital Fiberlink
7030 and 7040 Series Transmission Systems will be free from defects

as to the origin of any operational failure. Be certain that the input and
output signal connections are proper. Due to the number of positions,

Finally, although multimode and single mode devices may look the
same, they will not operate properly together. Using the wrong device
or fiber can easily add more attenuation than specified, resulting in poor
overall performance.

If, after reviewing these possibilities, the system is still not operat­ing, please contact the Customer Service Department for further
assistance. (See page 8 for contact information.)
