Checklist, Site Survey and Tools
CAUTION: Before performing an installation of a Motorola PTP 600 Series system, ensure
that you have read this entire guide and taken note of any safety information contained.
Checklist
•Check the contents of all packages against the packing list.
•Check the Web site for the latest software load.
List of Special Tools Required
•13mm wrench and 22 mm wrench for use with the glands
•RJ45 crimp tool (it must be the correct tool for the type of RJ45 being used)
•Personal Computer (PC) with 10, 100 or 1000 BaseT Ethernet
•Either Internet Explorer version 6 or higher, or FireFox 2.0 or higher are recommended.
•Ethernet patch cables
•Motorola PTP LINKPlanner report for this link
More information: PTP 600 Series User Guide Section: “Installation”
Pre-installation: Site Survey and Link Planning
A site survey must be performed to identify all the obstructions (such as trees or buildings) in the path and
to assess the risk of interference. This information is important if you are to achieve an accurate link
feasibility assessment.
The PTP 600 Series are designed to operate in Non-Line-of-Sight (NLoS) and Line-of-Sight (LoS)
environments. Link planning enables a link of known quality to be installed. This involves the acquisition of
path profile data (using Motorola’s free LINKPlanner utility). The LINKPlanner predicts data rates and
reliability over the path. It allows the user to try different antenna heights and RF power settings. When the
link is installed, the mean path loss can be checked to confirm that the predicted data rate and link reliability
is achievable. Motorola LINKPlanner is available to download from http://www.motorola.com/ptp/support.
More information: PTP 600 Series User Guide Section: “Site Planning”
Pre-installation: License Keys and Regulatory Conformity
If the units have been purchased as a pair (link) then the License Keys (at the end of this guide or
printed on a separate card in the box) will show how the units have been pre-configured to work as
a link. Software, license key, unit IP address, subnet mask, gateway address, target address,
master/slave and arming state are pre-configured.
CAUTION: Check that the link is configured with the correct Region Code. If Region Code
is incorrect, then re-configure the units with Alternative License Keys before installing and
commissioning the link. Refer to “Configuration Checks” for details on how to change the
License Key.
More information: PTP 600 Series User Guide Section: “Radio Link Planning and Regulations”
4Gon www.4Gon.co.uk [email protected] Tel: [phone] Fax: [phone]

5
Bench Testing (Optional)
It is advised that the link be configured and tested on a bench before the final installation of the
units on a pole or a mast. The following steps give details of how to connect an ODU to a PC in
order to check the configuration details, change the IP settings or modify the license key. For the
purpose of these tests, normal off-the-shelf Ethernet cables can be used.
Power Checks
Step 1: Connect the RJ45 at
one end of a cable to the ODU.
Step 2: Undo the retaining screw
of the PIDU Plus and hinge back
the cover.
Step 3: Plug in the ODU to
PIDU Plus Cable, ensuring
that it snaps home.
Step 4: Put the cover back
and tighten the screw.
Step 5: Plug in power lead using
a cable appropriate for the
installation.
Step 6: If the power LED
does not illuminate, remove
the power cable and the ODU
connection from the PIDU
Plus. Re-connect the power
lead and check the power
LED illumination (green). If
the power LED still does not
light then check the power
source.
Step 7: Connect a second
Ethernet cable (shown in
yellow) to the “LAN” socket of
the PIDU Plus.
Step 8: 45 seconds after
powering, the Ethernet LED
should be observed to flash
slowly 10 times. If the Ethernet
LED does not illuminate
(orange), then either the PIDU
Plus or the cable to the ODU
may be faulty. Replace cable
and/or PIDU Plus and repeat
from Step 1.
Step 9: Ensure PC is set to
correct IP address
169.254.1.x, where 2 < x <
254. Connect the LAN cable
to the PC.
If this IP address is not
recognised, try 10.10.10.11
(Master) and 10.10.10.10
(Slave), as some units may
have been pre-configured
with these addresses.
Step 10: If it is necessary to
use IP addresses 10.10.10.11
and 10.10.10.10, ensure that
the PC is configured with an IP
address of 10.10.10.n, where n
is any value between 2 and
254 but excluding 10 and 11,
to configure these units.
Step 11: Check that the Ethernet
LED is now ON. Step 12: If the LED does not show any activity when
accessing web pages, refer to
the Troubleshooting section
in this guide.

Bench Testing (Optional)
CAUTION: Do not dress the RJ45 cables too tightly, as this may make the connections
unreliable.
More information: PTP 600 Series User Guide Section: “Connecting Up”
Configuration Checks
Step 1: Use a web browser to connect to IP address http://169.254.1.1 for Slave and
http://169.254.1.2 for Master units. Select System Administration and Login (the
password is empty for new units). We recommend that you change the password by
selecting “Change Password.
Step 2: If an upgrade to the software is required, select Software Upgrade and follow the
on-screen instruction. Latest software is available from our web site:
(http://motorola.motowi4solutions.com/software/#ptp)
Step 3: Check the License Key information and ensure you are using the correct the
Region Code. Otherwise, select License Key and replace with the alternate key supplied
and reboot the unit.

Mast, Tower or Building Installation
Hoist and Safety Loop
Use the integral safety loop for hoisting the ODU up a mast, tower or building. When the ODU is in
position, use the safety loop as a fixing point to secure a permanent lanyard from the mast, tower
or building to the ODU, as a precaution against mounting failure.
WARNING: The safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard
must be made from a material that does not degrade in an outdoor environment.
WARNING: The safety lanyard must be fixed to a separate fixing point that is not part of the
direct mounting system for the ODU.
WARNING: If the safety loop or its fixing is damaged in any way or has been exposed to a
shock loading due to a fall, replace it with a new one before undertaking any further
operations.

Mast, Tower or Building Installation
Mast or Tower Installation Instructions
The ODU is pre-fitted with a mounting bracket (designed to ease installation) and with earth
bonding leads.
WARNING: When mounting the ODU, observe the following precautions against failure of
the assembly:
•Do not remove the pre-fitted mounting bracket from the ODU.
•Do not mount the ODU on poles with diameter less than 50mm (2”) or greater than
75mm (3”). The ODU mounting bracket is designed to work only with poles with
diameter in the 50 mm (2”) to 75 mm (3”) range.
•Do not over-tighten the bolts.

4Gon www.4Gon.co.uk [email protected] Tel: [phone] Fax: [phone]

10
Mast, Tower or Building Installation
The ODU must be mounted using the following steps, with cable entry at the bottom:
Step 1: Attach the bracket strap to the pole
using M8 x 70 mm bolts, M8 flat washers and
M8 coil washers. Tighten to ensure the
assembly grips but can be adjusted.
Step 2: Offer the ODU (with pre-fitted
mounting bracket) to the bracket strap and
affix using the captive M8 bolt.
Tighten to ensure the assembly grips, but can
be adjusted on the pole.
Step 3: Adjust the elevation and azimuth of
the unit before tightening to the required
torque settings of 14 Nm (11 lbft) for both
bolts.
Step 4: Attach the free end of one earth
bonding lead (large tag M10) to the tower
metal work.
CAUTION:
On no account must this be attached
to the mounting bracket bolts.
WARNING: A cable measuring card must NEVER be used at the ODU end connected to power
from the PIDU. It must only be used at the bottom of the mast with a multimeter. This is because
the PIDU voltage exceeds the limit allowed in some countries for safe handling in wet conditions and
therefore may create a safety hazard.

Cable Preparation and Installation
Cable and Gland Installation
To install the cables and glands, follow these steps:
Step 1: Make a cable as specified in “Cable
Preparation”. Plug in the RJ 45 into the ODU.
Step 2: Support the drop cable and gently hand
screw the gland body into the ODU until the O
ring seal is flush to the ODU body.
Caution:
Do not fit the back shell prior to securing
the gland body.
Step 3: Once the gland is fully hand screwed
into the ODU it may be tightened to a torque of
7 ftlbs/10Nm, with a 22mm wrench.
Step 4: When the gland body has been fitted,
tighten the gland back shell.
Caution:
Do not over tighten the gland back shell.
The gland on the right-hand side has been over
tightened. As a result, the internal seal and
structure have been damaged:
Step 5: Should it be necessary to disconnect
the cable at the ODU (or PTP LPU), this can be
achieved by removing the gland back shell first.
Then, wiggle the cable to release the tension of
the gland body as shown in the figure below.
Then you can unscrew the gland body and
depress the RJ45 locking tab with a small
screwdriver.
This is illustrated below.

Testing and Fault Finding (Troubleshooting)
Perform troubleshooting (fault finding) procedures either on a newly installed link, or on an
operational link if communication is lost.
When the link end hardware (PIDU, LPU, ODU and cabling) has been installed, start it by following
this procedure:
Step 1: Connect the RJ45 from the ODU (or LPU if fitted) to the PIDU and apply mains or
battery power to the PIDU. The green Power LED should illuminate continuously.
Step 2: After 45 seconds, the yellow Ethernet LED should be observed starting with 10 slow
flashes.
Step 3: Connect the RJ45 from the LAN port of the PIDU to the network. The yellow
Ethernet LED should blink randomly as traffic passes through.
If the Power and Ethernet LEDs do not illuminate correctly, test the link end as described in this
flowchart (references such as (*1) are to the tests on the following pages):

16
Testing and Fault Finding (Troubleshooting)
(*1) Power LED is Off
Unplug the ODU connection from the PIDU and check the power LED illumination. If the
power LED still does not light then check the power source.
(*2) Power LED is Flashing
Check that pins 4&5 and 7&8 are not crossed with pins 1&2 and 3&6 on the RJ45, and also
greater than 100K ohms between pins 1&8.
(*3) Ethernet LED did not Flash 10 Times
Check that the wiring to pins 4&5 and 7&8 is correct. For example, the wiring to pins 4 and
7 may be crossed.
(*4) No Ethernet Activity
Check that the wiring to pins 1&2 and 4&6 is correct. For example, the wiring to pins 1 and
3 may be crossed.
(*5) Irregular Ethernet Activity
The yellow Ethernet LED should blink randomly as normal traffic passes through. If the
Ethernet LED flashes irregularly, for example there is a short flash followed by a long flash,
this indicates that the ODU has booted in recovery mode. The causes may be installation
wiring or a corrupt ODU software load.
(*6) Connection is not 1000 BaseT
If the Ethernet connection to the network is only 10/100 BaseT, when 1000 BaseT is
expected, check that the wiring to pins 4&5 and 7&8 is correct. For example, the wiring to
pins 4 and 7 may be crossed.
(*7) Test RJ45 Resistance
If the above tests fail to diagnose the issue, there may be a fault in the wiring of the RJ45
cable that connects the ODU (or LPU) to the PIDU. Perform the following tests:
Step 1: Unplug the RJ45 cable from the PIDU and check that the resistances
between pins are correct as specified in Table 1.
Resistances should fall within + or -10% of the stated values.
Step 2: Ensure that there is greater than 100K ohms between pin 1 and ODU ground
for all cable lengths.
Step 3: Ensure that there is greater than 100K ohms between pin 8 and ODU ground
for all cable lengths.
Step 4: If GPS is not fitted, ensure that there is greater than 100K ohms between pin
1 and pin 8 for all cable lengths. If GPS is fitted, ensure there is greater than 2K
ohms between pin 1 and pin 8.
If a GPS Synchronization Box has been installed, but one or more of its status LEDs are not
illuminated, refer to “Test GPS Synchronization Box” in the User Guide.

Installation and Commissioning
Aligning the PTP 600 Series Bridge ODUs
The PTP 600 Series Bridge uses audible tones during installation to assist the installer with
alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation until
highest pitch tone is achieved.
The pitch of the alignment tone is proportional to the received power of the wireless signals. The
best results are usually achieved by making small incremental movement in angular alignment.
The tones and their meanings are as follows:
State Name Tone
Description State Description Pitch Indication (Higher pitch = higher power)
Free Channel
Search Regular beep Executing band scan N/A
Scanning Slow broken tone Not demodulating
the wanted signal Rx Power
Synchronized Fast broken tone Demodulating the
wanted signal Rx Power
Registered Solid tone Both Master and
Slave units
exchanging Radio
layer MAC
management
messages
Rx Power
The term ‘wanted signal’ refers to that of the peer unit being installed.
In each of the states detailed above, the unit should be aligned to give the highest pitch tone. It
should be noted that if, when in the Synchronized or Registered state, the tone varies wildly, you
may be suffering from interference or a fast fading link. Installing in this situation may not give a
reliable link. The cause of the problem should be investigated.
For the ease of alignment, both Master and Slave units use the install tones in the same way but
with some small behavioral differences. This allows the installer to install the Slave unit first and
carry out the initial alignment with the Master unit if desired. However, due to the behavioral
differences of Master and Slave units, it is recommended that the Master unit is installed first and
the initial alignment carried out at the Slave unit.
Once the optimum performance has been achieved by directing the Slave unit (indicated by
highest frequency of tone) then adjustment of the direction of the Master unit should be done
without moving the Slave. Repeat if necessary at the Slave and then the Master until optimum
alignment has been obtained.

Installation and Commissioning
Behaviour During Installation
The following behavior should be noted:
•Band scan: When first started up and from time to time, the Master unit will carry out a band
scan to determine which channels are not in use. During this time, between 10 and 15
seconds, the Master unit will not transmit and as a consequence of this neither will the Slave
unit. During this time the installation tone on the master unit will drop back to the band scan
state, and the Slave unit will drop back to the Scanning state with the pitch of the tone set to
the background noise level. Alignment of the unit should cease during this time.
•Radar detection: If the unit is operating where mandatory radar avoidance algorithms are
implemented, the ranging behaviour for the PTP 600 Series Bridge may be affected. The
Master has to monitor the initially chosen channel for 60 seconds to make sure it is clear of
radar signals before transmitting. If a radar is detected during any of the installation phases,
a further compulsory 60 seconds channel scan will take place as the master unit attempts to
locate a new channel that is free of radar interference.
•Ranging: The Master unit can take up to 60 seconds in 0-40km (0-25 miles) mode, 90
seconds in 0-130km (0-81 miles) mode and 120 seconds in 0-200km (0-124 miles) mode to
determine the range of the link being installed. The Master unit will remain in the Scanning
state until the range of the link has been established. The Master unit will only move to the
Synchronized state when the range of the link has been established.
•Retrying same channel: If, at the end of the ranging period, the Registered state is not
achieved due to interference or other reasons, the Master unit will retry twice more on the
same channel before moving to another available channel. Should this occur it might take a
number of minutes to establish a link in the Registered state.
•Slave unit: The Slave unit does not have a ranging process. The slave unit will change to
the Synchronized state as soon as the wanted signal is demodulated.
