2. INSTALLATION
The standard installation is summarized in this section. Included herein is
information on typical installation work flow and guides for MDP
installation, TRP installation, Antenna (ANT) installation, waveguide
connection and coaxial cable connections. The installation flow diagram is
shown below.
This product is a part of radio link system, and is intended to be connected
with a external antenna.
This product will be installed and operated by professional.
After installation, the professional person shall make sure that the system
shall comply with the relevant limits for general public exposure specified
as basic restrictions or reference levels in the council Recommendation
1999/519/EC.

2.5 TRP Mounting
The procedures for mounting and demounting the TRP are described here.
There are two types of mounting for the antenna direct mounting type and
waveguide connecting type. The TRP should be installed in the radio
station. The tools for installation are listed in Table 2-1.
Table 2-1 Tools
TOOLS
Wrench or Monkey wrench
Screwdriver
Torque Wrench
Cautions: 1. How to use small and large O-rings are shown in
following table. Two (small and large) O-rings are
attached in 18 to 38 GHz band Andrew/RFS direct
mount antenna. 11 GHz band antenna does not have
small O-ring (Small O-ring is not used for Andrew/RFS
direct mount antenna). If the small O-ring is used for
TRP direct mount installation, a gap may occur between
TRP and antenna for RF interface. Therefore it may
happen transmit or receive level down.
2. Do not apply silicon grease at O-ring.

antenna, it must be changed to a circular type.
2. When mounting the TRP to the OMT, confirm the
polarization for Main Master and SUB Master TRP. The

other reasons, fix the attached short plate to the
demounted port of the OMT to avoid leaking of RF
power from the OMT and for waterproof.

Pass the tightening nut, the washer and the gasket on the cable in
the order shown in the figure.
Then, strip the cable jacket in the diameter shown in the figure.
[Applicable cable: 8D-FB-E]
Notes: 1. Be careful of insertion direction for the gasket and the
tightening nut.
2. Be careful not to damage the outer conductor.
3. Do not reuse the gasket because the clamp deforms it after
tightening.
Insert the clamp to clamp the stripped cable jacket end. Open the
end of the outer conductor a little,

Step
Procedure
Note: It is recommended that TNC (Male) L-angle connector for the
8D-FB IF cable is used to connect it to the MDP. When the N
(Male) straight connector is attached to the 5D-FB or 10D-FB
IF cable, use of the TNC (Male) - N (Female) (NJ-TNCP-LA)
L-angle adapter is needed.
Pass the tightening nut, the washer and the gasket on the cable in
the order shown in the figure.
Then, strip the cable jacket in the diameter shown in the figure.
[Applicable cable: 8D-FB-E]
Notes: 1. Be careful of insertion direction for the gasket and the
tightening nut.
2. Be careful not to damage the outer conductor.
3. Do not reuse the gasket because the clamp deforms it after
tightening.
Insert the clamp to clamp the stripped cable jacket end. Open the
end of the outer conductor a little,
Insert the hood between the plastic tape with aluminium foil and
the outer conductor,
Note: Use the insertion stick to open the hole of about φ9. No gap is
allowed in between the clamp, the outer conductor and the hood.

Included is information on start-up, shut-down, MDP and TRP equipment
setting, antenna orientation and lineup test between two stations.
When the PASOLINK Monitor is used for RX LEV monitoring, connect
the X0818 PASOLINK Monitor to the TRP. The PASOLINK Monitor
operates on a dry battery (6F22/9 V).
Notes:
1. Insert the battery with correct polarity.
2. When the PASOLINK Monitor will not be used for extended
periods of time, remove the battery to avoid damage from
battery leakage and corrosion.
3. When the PASOLINK Monitor will be connected to the TRP,
control corresponding TRP to Antenna Alignment mode
using LCT in Maintenance ON.

3.1 Start-up
The procedure for starting the equipment is shown in Chart 3-1.
Warnings: 1. The –48 V DC is superimposed on the centre conductor
of the IF coaxial cable between the MODEM and the
TRP. Connecting test equipment directly to this terminal
may damage it and touching the coaxial cable core may
cause electrical shock.
2. Do not disconnect the IF cable between the MODEM and the
TRP in operating condition, to avoid damaging the NLite N,
turn the MDP power OFF before connecting/disconnecting
the IF cable.
3. Do not allow open or short circuit of TRP TX output with
the TX power on conditions. Perform the TX Mute
control in the Maintenance mode or turn the PWR switch
off at the MDP before disconnecting cable or feeder from
the TRP TX output.
4. After turning ON the equipment, wait at least 1 minute before
turning it OFF again. Repeatedly turning the power ON and
OFF within a short interval may cause the NLite N to fail.
Cautions:1. Be careful top surface above MODEM of the MDP and
the TRP are hot in operation.
2. When replacing the MODEM, 2P LAN INTFC or DC-DC
CONV (optional) turn off the PWR switch and disconnect all
cables connected to the module which is to be replaced.
3. When dismounting the ( ) INTFC, turn off the PWR switch on
the MODEM and disconnect all cables connected to the ( )

Safety Guideline for Microwave Radiation Hazard
The Microwave and Millimetre-wave that NLite N series are treating is very small radiation level and
never been reported to effect human health. But advanced countries about health hazard have started to
regulate the radiation levels. In case of EU country, it is specified by EN50385. In order to keep the
regulation, the operator shouldn't work at near parabolic antenna during transmitter activating.
Especially the area in side to front of antenna shows higher radiation level. (please see below figure and
calculation sample 1).
On the other hand, in case of front side of antenna, the power density becomes high level along antenna
beam. Therefore the user of this system should pay attention not to radiate the beam against humans
any time. (Please refer below calculation sample 2)

100m for Calculation example 2

Hazard Area of Radiation
In addition, the Power density and Field strength level is calculated by equation below.
P+G−30
10 10 × K
Power density S (mW/cm2) =
40 × π × R2
Where:
P = Output power of TRP (dBm),
G = Antenna Gain (dBi),
(in consideration of the angle from antenna)
K = Reflection factor =2.56 (given),
R = Distance between Human and Antenna (m)
Calculation example 1, (90 degree side of antenna)
NLite N = 18 GHz/+23 dBm,
Antenna diameter = 0.6 m,
0 degree antenna gain = 39 dBi,
90 degrees side antenna gain = −24 dBi, (90 degrees attenuation = −63 dB),
Distance = 0.1 m
Power density S (mW/cm2) = 0.0016 ≤ 0.01 (European safety guideline)
Calculation example 2, (0 degree, front side of antenna)
NLite N = 7 GHz/+27 dBm,
Antenna diameter = 1.8 m,
0 degree antenna gain = 40 dBi,
Distance = 100 m
Power density S (mW/cm2) = 0.01 => Equal to European safety guideline

The DADE adjustment is needed in initial lineup or when the IF CABLE is replaced. It
is not needed readjustment when the INTFC status is indicated In-phase. The setting
conditions are as follows:
DADE:
Automatically adjust delay time based on either No.1 signal or No.2
signal which it is selected by RX SW under the Outphase condition of the
INTFC status. The DADE control is processed assuring no interruption of
traffic.
Offset DADE:Automatically adjust delay time based on either No.1 signal or No.2 signal
which it is selected by RX SW under the Outphase condition of the INTFC
status. Since the offset memory minimizes the latency delay, traffic
interruption occurs at that moment. This Offset DADE controls the delay
time difference to a minimum than DADE control.
DADE off: Set when DADE function is not used. For particularly, when low bit rate (10
to 20 MB) transmission is applied to the system, the DADE control is not
required.
