INSTALLATION INSTRUCTIONS
Installation Procedure:
The Pure Digital Fiberlink
®
7250 Series transmission system is ready
for immediate use. There are indicator LEDs on the units for monitor-
ing purposes. The following instructions describe the typical installa-
tion 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 Pure Digital Fiberlink
units. Each fiber may be connected to either Optical 1 or Optical 2 on
the receiver, regardless of which output (1 or 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.
DANGER! The transmitting element in the Pure Digital Fiberlink 7250 transmitter
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.
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 Pure Digital Fiber-
link units. For box versions using DC
power connections, refer to Figure 1.
6. When power is applied, the green
POWER LED will 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.
Note that the rack card version has an additional red LED for
indicating the presence of an alarm condition (loss of signal). Refer
to the table on the following page for alarm enables.
