The Lynx radio products do not have an on/otf switch Power to the ODU is
provided by the DU via the two coax cables
GND This is a grounding post to connect to earth ground.
RSL This is a test point (BNC connector on the ODU) that relates to the Received Signal
Level (RSL), The voltage is measured with a voltmeter (using the GND test point for
reference) which corresponds to the actual power level of the incoming received signal.
See RSL chart that gives volts to RSL conversion in Figure 38.
This voltage only applies to the nee/end and does not allow measurement of
the far—end output transmit power, even when the DISPLAY FAR END button
is pressed unlike other models of the Lynx family
The Lynx system requires professional installation, Transmitted output power
® limits may apply when using this radio. Consult FCC, IC, Western Multiplex or
' other regulatory authorities [or limits which may apply. See Section 3 13.1 for
details on setting output power.
Do not adjust output power above factory settings.

3.2 Packing Items identification
The primary shipping container houses the radio along With other items including:
:~ This manual
Installation accessory kit (see Section 2.5)
3.3 Before Installation Task List
There are several Iasks that should be accomplished prior to installing the Lynx radio system. This
section briefly describes the follownng:
- Site selection
- Lined-Sight and Path Clearance determination
- Anticipated RSL calculation
~ Fade margin calculation
- Availability calculation
» Frequency plan determination
- Power supply planning
— Antenna (and acoessones) purchase
Only directional antennas should be used with Lynx radios. These are
typically flat panel or solid parabolic antennas. Western Multiplex
® recommends a maximum beamw/dln of 10 degrees for directional
' systems.
3.3.1 Site Selection Requirements

- access to the appropriate power
- close proximity to the telephone or computer system you Wish to interconnect
- Iine-ol—sight to the other radio location with adequate clearance
- location for mounting the antenna
3.3.2 Line-of—Sight and Path Clearance Guidelines
The Lynx radios will not operate properly unless they have lineal-sight between their corresponding
antennas The Lynx radio transmission will not pass through trees or other obstacles. Factors to
consider include:
- Earth curvature
- Future growth of trees
- Height of buildings
In addition to the Iine-ol—sight requirement, a well-engineered path will also have additional path
clearance to allow Ior signal loss due to partlai obstruclions. atmospheric ducting and ground
reflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated and this
distance added to the path clearance (in addition to trees or buildings).
3.3.3 RSL Calculation and Link Budget
The received signal level (RSL) can be estimated using the following formula:
RSL (dBm) = PM - FL‘+ (51+ G: - FL2 - LP
where: PM is the transmitter output power (in dBm)
FL\ is the feeder loss of the transmit side (in dB)
Q Is the gain of the transmit antenna (in dB)
G2 is the gain of the receive antenna (in dB)
FL2 is the feeder loss of the receive side (in dB)
L" is the Path loss, defined by:
L9 (as) = 95.6 + 201°ng + 2010ng

where: F = Frequency in GHz (2.4 or 5.8)
D = Distance of path in miles
This link budget is very important for determining any potential problems during installation. If you have
calculated the expected RSL, you can see if it has been achieved during installation, and troubleshoot if
necessary.
3.3.4 Fade Margin Calculation
The fade margin is the difference between the actual received signal and the radios threshold. Using the
formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to the
specified threshold of the Lynx radio (shown in Section 2.2) and calculate the fade margin as the
difference between the two signal levels.
3.3.5 AvailabilityCalculation
3.3.6 Power Supply Planning
3.3.7 Antenna Planning
Using path planning mathematics, proper antenna Size can be determined which will yield the desired
path performance. In general, the larger the antenna that is used with the Lynx radio. the better the link
will perform. Larger antennas have narrower beamwidth and higher gain, which WI|| yield better link
performance (higher Iade margin, better availability) and improve immunity to interlerence (due to the
smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller
antennas, in some cases requiring special equipment for installation, All of these factors should be
taken into consideration when selecting antennas.
| In areas where transmitted output power restrictions apply, the use of
®l larger antennas will maintain the benefit of narrow beamwidths and
I receive gain, However, output power may need to be reduced to meet
regulations, {See Section 3 13.1)
Prior to installation, the specific antenna location and mounting should be determined. This advanced
planning also yields the transmission line requirements.
_ _, Both single and dual-band/dual-polarized directional antennas can

to upgrade to a higher capacity radio link later on. Both single and
dual—polarized on presented on the following pages.

3.4 Tools Required
3.5 Mounting the Lynx Radio
The Lynx radio can be mounted at any height in a standard 19-inch rack, Blank rack-mounting spaces
above and below the Lynx are recommended, especially if the surrounding equipment dissipates a
considerable amount of heal.
The Lynx radio may be set up for mounting with the front edge projecting from the lront face of a
standard 19-inch rack using Ihe rack mounting brackets enclosed with the screws in the Accessory Kit
(4 per bracket). The rack mounting brackets may be reversed, in order to install for flush or cabinet
mounting if preferred Depending on rack configuration, it may be necessary to remove the four adhesive
backed rubber feet on the bottom of the unit,
The Lynx radio has internal fans which intake and exhaust on the
Q‘ left and right sides of the chassis When rack mounting, it is
important to leave a small gap between the outer edges of the
radio and the inside edge of the rack
The Lynx radio IDU may alternatively be placed on a table or shell
attached to a wall Because of the low weight of the radio, any mounting
option other than rack mounting will be less secure
Even though the lDU can be mounted at any level within the rack, it is
best to mount it as high as possible to minimize the routing of the thicker
coaxial cable, By hawng the RF connection at the top of the rack, there is
easier access to other rack mounted user equipment

3.6 Power Connection and Wiring
There is no ON/OFF switch on the radio bridge. As soon as
power is applied, the equipment will be operational. This
means that there can be up to 1W of RF power present at the
antenna port. The antenna port should be terminated before
power is applied.
Power is connected using the DC power plug contained in the Accessory Kit. Use Table 30 or 30
along With the associated diagram of Figure 33 or 34 to connect the DC power cables. For example,
for a negative DC power input, use Table 3C and Figure 33. Use 14 gauge wire as the minimum size.

3.6.1 DC Power Wiring
Connect the power cable with adequate current rating (minimum of 18 AWG. recommend 18 AWG) to
the terminals shown on the removed (not plugged into lhe radio) DC power plug usmg the screw
connections. The recommended minimum current rating of external fuses and cables is 5 Amps The
Lynx radios consume less than 3.1 Amps at 148V. Be sure the DC power cable is less than 3 meters
(9.75 feet) in length and not less than stranded 14 gauge in size
Each Lynx termmal should be externally fused separately with a 8
Amp maximum fuse. The DC power cable must be less than three
(3) meters in length. Use 14 gauge wire as the minimum size
If using negative powerl connect the negative voltage to leS 5 or 6, Connect the ground return
connection to pin 1 and use an optional jumper - 2 to 3 for ground reference. See Figure 3-3.
if using positive power. connect the positive voltage to pins 1 or 2. Connect the ground retum
connection to pin 6 and use an optional jumper - 4 to 5 for ground reference. See Figure (M.
The ground connection is available at pins 3 and 4. Either pin may be used to ground the return side of
the power supply. Do not ground both sides of Ihe power supply.
' Proper grounding, either through the chassis and/or the power supply.
©' can be very important for protection from lightning. A grounding screw
and nut (WHO) is prowded on the left front panel.
The ground connection may be left floating if the power supply lS
referenced to ground externally and to avoid ground loops In some
configurations. However, this may not provide adequate grounding for
lightning protection. Be sure to use the local electrical code to
determine wire srze and proper connection to the grounding screw.
Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug.
1 Do not connect the DC power plug to the front of the Lynx lDU until
©| the ODU is connected via coax).
