Devices returned collect or without authorization may not be accepted.
2. Prior to repair, Foxcom will advise the customer of our test results and
any charges for repairing customer-caused problems or out-of-warranty
conditions etc.

1.2 Reporting Defects
The units were inspected before shipment and found to be free of mechanical and
electrical defects. Examine the units for any damage which may have been caused in
transit. If damage is discovered, file a claim with the freight carrier immediately.
Notify Foxcom as soon as possible.
Note
Keep all packing material until you have completed the inspection.

1.3 Certification
The 7320 IFL has CE, FCC, FDA, and UL certification.
1.4 Conventions
In this manual the following special formats are used:
Note
Notes contain information detailing the current topic.
CAUTION
Cautions contain information regarding situations or materials which could
damage your product.
WARNING
WARNINGS CONTAINS INFORMATION REGARDING DANGEROUS
FUNCTIONS.
1.5 Precautions
1.5.1. Personal Safety
WARNING
OPTICAL RADIATION
APPLYING POWER TO THE TRANSMITTER UNIT WILL CREATE A
LASER ENERGY SOURCE OPERATING IN CLASS I AS DEFINED BY
IEC 825-1. USE EITHER AN INFRARED VIEWER, OPTICAL POWER
METER OR FLUORESCENT SCREEN FOR OPTICAL OUTPUT
VERIFICATION.
AC POWER HAZARD
THE RACKMOUNT POWER SUPPLY LINE IS EMI FILTERED AND
FUSED. THE CHASSIS IS CONNECTED TO EARTH GROUND IN
COMPLIANCE WITH SAFETY REQUIREMENTS. ALWAYS USE THE 3
PRONG AC PLUG WITH EARTH GROUND TO AVOID POSSIBILITY OF
ELECTRICAL SHOCK HAZARD TO PERSONNEL.

Foxcom Proprietary Information 8
Document No. 93-005-28-C
1.5.2. Equipment Safety
To avoid damaging your product, please observe the following:
1. Fuses: To avoid possibility of fire hazard, always replace fuses with the
same type and rating of fuse as recommended on the power supply rear
label.
2. The input of the transmitter has an optional built-in bias for inserting DC
power up the coax to the LNB. Make certain any equipment or test
equipment connected to the transmitter input can withstand this bias.
3. The output of the receiver is AC coupled and can withstand the bias from a
satellite receiver. Do not exceed 25V DC bias.
4. Do not allow any dirt or foreign material to get into the optical connector
bulkheads. This may cause damage to the polished optical connector end
faces.
5. The optical fiber jumper cable bend radius is 3 cm. Smaller radii can cause
excessive optical loss and/or fiber breakage.
6. If multiple transmitters are installed in the chassis allow sufficient room for
adequate ventilation; otherwise the units may overheat causing possible
safety hazard or equipment damage.
7. When several units are installed on one 7000M chassis, ensure that the total
units’ current (including any LNB bias) does not exceed 2A per power
supply (e.g. if there are two power supplies the current should not exceed
4A.)

2. Introduction to the 7320 IFL
The Sat-Light7320 IFL transmits an L-Band RF signal over singlemode fiber from a
satellite antenna LNB to control room equipment up to two kilometers away. The 7320 IFL
consists of an optical transmitter (7320T) which receives the L-Band signal from the LNB
and an optical receiver (7320R) which connects to a satellite receiver.
The 7320T and 7320R modules plug into a 7000M 3U chassis/power supply which enables
expansion of the system to accommodate any 6 Sat-Light modules. Accessories include the
Model 7000S Standby Power Supply, the Model 2000 1:1 Redundant Switch, the Model
2100 Amplifier, and the Model 7050-4 Serial Data Multiplexer, an asynchronous data link.
The 7320 IFL is a broadband transmission link; all standard satellite modulation formulas can
be transmitted (i.e. QPSK, FM, etc.).. The RF signal is directly modulated and adds virtually
no phase noise to the original signal. The direct modulation, coupled with the 7320 Links RF
circuitry, guarantees superior signal quality. The 7320 gives more than 25 dB carrier to noise
performance in a full multichannel environment.
Gain Control provides for optimization of the RF signal. LEDs, and back panel monitors and
alarms allow for complete system status monitoring and for interfacing with M & C systems.
2.1 Options
The 7320 IFL comes with a variety of options:
1. LNB powering - The transmitter unit can provide 15 VDC for optional LNB
powering.
2. 50 ΩInput/Output Impedance/BNC RF connector. Standard impedance is
75 Ω/F type, female connectors are standard.
3. Standalone unit - The 7320 IFL can be installed as a standalone unit. If the 7320
is used as a standalone, a separate power supply must be used.
On the side of the 7320T and the 7320R units is a sticker1which lists options 1 & 2.
Under each option is a square. If the unit includes a particular option the square under
the option should be marked. For example in Figure 1 the LNB option is marked.
