Installation Instructions
The FiberLink 7250 Series transmission system is ready for immediate use . There are indica-
tor 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 cables between the two FiberLink units . Each fiber may be con-
nected to either Optical 1 or Optical 2 on the receiver, regardless of which output (1or
2) each one is connected to on the transmitter . The system will still operate properly
if the fibers are cross-connected . However, please note that any difference in length
between the two fibers must not exceed 20 meters .
4 . Connect the audio input signals to the transmitter stereo jack and the audio output to
the receiver stereo jack .
5 . Apply power to both FiberLink units . For box versions using DC power connections,
refer to Figure 1 .

light, indicating the presence of operating power .
The VIDEO LED will give an indication as described
on page 7 .
7 . The green AUDIO LED will give an indication as
stated on page 7 .
8 . The system should now be operational .

alarm condition (loss of signal). Refer to the table on the following page for alarm enables.
Installation Instructions
The transmitting element in the FiberLink 7240 and 7241
transmitter unit contains a solid state Laser Diode located
in 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 with no fiber optic cable connected to the
optical connector, may be sufficient intensity to cause
instantaneous damage to the retina of the eye. Direct
viewing of this radiation should be avoided at all times!
