“Link System Manual 86101545
Installation efthe uLink is described under the
following four main headings:
a, Installing the Outdoor Unit (OU) and Integral
Antenna.
b, Installing the Indoor Unit (IU).
c, Installing the IU/OU Interconnection Cable.
d. System Commissioning,
Appendix A at the end of this chapter supplements the
installation procedure. It provides connector pin
details for the external connectors ofthe IU and OUs.
Installation
Overview
Antenna Follow these steps to install the Antenna,
Installation
Step Action C
1. Secure the C~shaped mounting bracket to the
Antenna using the two securing screws and
bolts (see Figure 6).
2, Position the antenna in the required position on
. the pole, Note the orientation of the antenna.
3. Secure the antenna to the pole by tightening the
mounting bracket securing nuts (two nuts on
either end ofthe pole clamp).
CAUTION
ENSURE THAT THE POLE IS EARTHED FOR
LIGHTNING PROTECTION ACCORDING TO
STANDARD LOCAL PRACTICES.

Installation
Follow these steps to install the IU. See Figure 8.
Step Action
1. Install the Data Interface module into the [U by
sliding it in until the male connector on the
module mates firmly with the female connector
inside the lU.
2. Secure the Data Interface module to the It)
with the two (2) x M4 screws provided.
3. Slide the lU into the 19" raCk and secure to the
rack using four (4) X M3 screws. Note that if
the Unit is to be table mounted, first fit the four
(4) x rubber feet to each comer on the base of
‘ the IU. .
C ' 4. Eanh the IU by connecting the earth cable or
strap between the station earth and the earth
stud on the lU rear panel.
5. Observing the polarity ofthe supply, wire up
the supplied power connector cable plug and
connect it to the facility DC supply (21 to
55 V) through a minimum lO A circuit breaker.
Secure the connector screws to the unit. Check
the supply voltage using the Multimeter.
OR
Connect the AC power cable from the station
power source to the AC power connector on
the rear panel ofthe IU.

6. Make~offthc lZOQ (EU/1009 (Tl) - factory
set tributary input and output connections and
connect to the RJ-lz connector on the rear
panel ofthe IU. Alternatively, connect the
750 (factory set) coaxial tributary connection
to the BNC input and output connectors on the
IU rear panel as required. See Appendix A at
the end of this chapter for the pin details ofthe
relevant tributary connector type.
7. Connect the 15-pin D-type Auxiliary I/O
Connector (alarm interfaces) on the rear panel
of the IU to the appropriate Krone block or
other distribution rack (for further connection
to appropriate supervisory equipment as
required). See Appendix A at the end ofthis
chapter for pin details.

CAUTIONS
DO NOT EXCEED THE RECOMMENDED
BENDING RADIUS OF THE CABLE, IE. 10 cm.
DO NOT OVER TIGHTEN THE CABLE STRAPS
ON THE CABLE AND DO NOT FASTEN THE
ACTUAL STRAP LOCKING MECHANISM OF
THE CABLE STRAP ONTO THE CABLE.
Step Action
1. Connect the interconnection cable to the
connector on the base of the Outdoor Unit (see
Figure 9).
2, Using cable ties or straps, secure the cable to
the pole at regular intervals.
3. Connect the other end of the interconnection
cable to the Outdoor Unit connector on the IU
rear panel (see Figure 8).
A. Tighten the Outdoor Unit connector securing
screws on the lU rear panel.

System After completing the physical installation of the indoor
Commissioning Unit, Antenna and Outdoor Unit, and the
Interconnection Cable, you must commission the
System. This describes how to set up the minimum
requirements {or successful uLink System operation.
information Before commissioning the system, you should know
Required the proposed frequency band plan (Tx and Rx) for each
station. and the PN sequence for the link.
Commissioning Setting-up Procedure
Procedure
Perform the following steps at both stations:
- Locate the far site and point the antenna to the
antenna at the far site, as accurately as possible.
- Switch the XU power ON,
- Install and Access the uLlnk Management Soflware
(refer to Chapter 4 ofthis manual).
- Configure the radio channel as required.
- Configure the Tx and Rx PN sequences.
- Set the Tx power to maximum.
Beaming-up
l. Check the RSSI and BER levels.
2. Align the antenna until the Maximum R551 and
minimum BER levels are attained.
Set Critical Parameters
l. Reduce the Tx power until an RSSI of between —65
and -70 dBm is obtained, This is important to
avoid interference to co-located systems.
