About This Guide
LigoWave Page 8
The PTP link consists of two units, one on each end: Master and Slave. Master unit operates as an
access point; therefore the Slave connects to the Master and operates as a client.
Figure 1 – Point-to-Point Link Elements
From the point of view of the administrator the Local unit is the one with the direct connection to the
Web management interfaceand the Remote unit is the one which is connected to the Local unit in
PTP link. The concept of the Local unit and the Remote unit is not related to the operating mode
(Master or Slave). This terminology will be used throughout the manual, particularly in the description
of statistics.
Introduction
LigoWave Page 9
Application Examples

The default administrator login settings for PTP unit are:
Login: admin
Password: admin01
After successful administrator login you will see the main page of the PTP unit Web
management interface. The PTP unit now is ready for configuration.
Step 2. Specify the operation mode: Master or Slave.The difference in configuration of Master
and Slave is that the frequency does not need to be specified for the Slave. The Slave
scans the air and chooses the frequency automatically after finding the Master.
LigoWave Page 14
Step 4. Set Frequency at which PTP link will operate on Master unit. Change Frequency
applies only for Master units.The Slave unit will choose the frequency automatically after
the Master unit will be found. For instructions on changing this setting refer to the
Radiosection in the Web management chapter.
Figure 8 – Specify Frequency
Step 5. Set Channel width at which PTP link will operate. For instructions on changing this
setting refer to thesection in the Web management chapter.
Figure 98 – Specify Channel Width
LigoWave Page 15
Step 6. Set link encryption for secure data transfer between PTP units.The security settings
(encryption and passphrase) must be the same on each side of the link otherwise the link
will not establish. For instructions on changing this setting refer to theRadiosection in the
Web management chapter.
Figure 9 – Set the Encryption
Step 7. Reduce Transmit Power before testing the units placed on a table. PTP units placed in
short distance with high transmit power may not work or even damage the peer's radio’s
receiver.
Step 8. Change web management login password. This is strongly recommended for security
reasons.For instructions on changing the administrator’s password refer to the
corresponding sectionAdministrative Account.
Figure 10 – Change Administrator's Password
Step 9. Save configuration and Reboot the device.
LigoWave Page 16
Figure 11 – Save Configuration
Step 10. Setup the second unit of the PTP link in the same way and check if configured units
established a Link.
Verify PTP Link Connection
After the both units of the PTP Link are configured, verify the PTP link quality:
Step 1. Connect to the unit’s web management interface.
Step 2. Check the Signal Indicator bar located at the bottom of the web management interface:
Figure 12 – Signal Indicator Bar
LigoWave Page 18
Figure 13 – iperf Results (TCP)
LigoWave Page 19
Figure 14 – iperf Results (UDP)
Step 4. If test results are meeting the requirement and are no configuration will be done
Transmit power should be increased, before mounting PTP units outside. Note that if
the distance between the units is short, do not set Transmit Power to the maximum
value. Observe the Signal Indicator bar – if it is red, decrease the Transmit Power.
LigoWave Page 20
Align Antenna
Avoid standing directly in front of an operating antenna while aligning.
The PTP units are equipped with two signal strength feedback systems: antenna alignment tool on
the Web management interface and antenna alignment tool on the OLED screen.
Follow the steps to establish a radio link between the two PTP units and align the units for the best
signal strength.
Step 1. Ensure that power is supplied to both PTP link units.
Step 2. Ensure normal operation of the unit: check the OLED screen or Status page on the
Web management interface.
Step 3. Run the Antenna Alignment tool on the selected interface (OLEDor Web management)
and move the antenna in the horizontal and vertical planes until the maximum RSSI
visible on the Antenna Alignment graph is achieved.
Figure 15 – Antenna Alignment Tool on Web Management Interface
Figure 16 – Antenna Alignment Tool on OLED
For detailed instructions on Antenna Alignment tool, refer to the respective sections:
Web management – Antenna Alignment
OLED screen –OLED control
Step 5. After the maximal RSSI is reached, tighten down the unit in the optimum position.
LigoWave Page 21
PTP products are designed to provide superior performance at long range distances. With a
proprietary wireless driver that was written for the sole purpose of optimizing wireless point to point
links, one can achieve much higher throughput, especially at longer links, than standards based
products.
General Operation
This section provides information about concepts used in PTP unit’s Web management interface.
Instant Changes
Some of the PTP radio parameters do not require to reboot the device. These parameters are named
as instant changes.
Instant changes are useful for best performance parameters tuning. These parameters will take effect
as soon as the Apply button is clicked. When best configuration is founded press Save button and
reboot the device to make changes permanent. Otherwise all instant parameter changes will be lost
during PTP unit reboot.
Instant changes are on theRadiosection.
System Warnings and Errors
There are 3 types of system messages that must be noted: notifications, warnings and error
messages. These messages appear at the bottom of the page and can be closed by clicking the sign
.
For example notification messages are displayed in brown color and contain information about
configuration changes:
Figure 17 – Notification Message (1)
This message has an implemented Reboot button. Simply click this button and the PTP unit will be
rebooted at once – there is no need to navigate into theMaintenance page for additional action to
reboot the unit.
Notification messages also are on Wireless page Instant changes. This message informs you about
instant changes that were made:
Figure 18 – Notification Message (2)
Web Management
LigoWave Page 22
Warning messages are displayed in red and contain PTP unit’s system cautions:
Figure 19 – Warning Message
The PTP unit contains built in validation for configuration settings in the web management interface. If
a user sets an incorrect value in the entry field, its frame turns red, and if the user tries to save such
incorrect configuration, an error message appears at the end of the page:
Figure 20 – Error Message
Signal Indicator
The PTP web management interface has a PTP link signal indicator. This indicator displays real-time
signal level in dBm of the Local and Remote units.
Figure 21 – PTP Signal Indicator
LigoWave Page 23
The color of the Signal indicator will change according to the signal level quality of the unit. The green
color means excellent link quality while the red color of the indicator means that link quality is poor.
The red circle beside full filled red indicator switches on immediately when the signal level becomes
too high and overload is detected.
Figure 22 – PTP Signal Indicator (too Strong Signal)
This may happen on an incorrect link layout, for example, in the case when the TX power parameter
in the PTP units is set to maximum but physically the units are too close to each other (e.g. testing
units are placed on a table).
The screenshot below displays Signal indicator if there is no PTP link established between PTP units:
Figure 23 – PTP Signal Indicator (no Link Established)
LigoWave Page 24
Status
Use the Status menu to check the current status of the PTP unit and established link (this is the
default page when accessing the device’s web management interface). The Information page displays
generic information and status of the PTP unit. The page is divided into three main categories:
System, Network and Wireless. The System section displays the identification information of the PTP
unit. The Wireless section presents main wireless settings. The Ethernet section describes the PTP

A) Run PTP Link in Small Distance
Follow up the steps to run the PTP link for testing it in small distances (e.g. testing on a table) and
achieve throughput up to 70 Mbps.
Step 1. Power-up both units: Master and Slave.
Step 2. PTP units must be placed at least a distance of 2 meters from each other.
Step 3. Change major Radio parameters for both units (Master and Slave):
Figure 52 – Radio Settings
Channel width: 40 MHz
Transmit power:5dBm
Multipath protection:off
Mode:MIMO 2x2
Appendix
LigoWave Page 48
Data rate: 300 Mbps
ACK timeout:Distance 0 km/miles
Click Apply button for configuration to take effect.
Step 4. Observe theSignal Indicatorbarat the bottom of the screen. If it is green the quality of
the link is excellent whereas the red color indicates a poor quality of the link. If results
do not meet the requirements increase or decrease the Transmit Power on Radio page
depending on the status of the Signal Indicator bar. TheSignal must be approximately
25-30dBm.
Step 5. Start the testing: start the iperfserver , then iperf client:
Figure 53 – iperf Results (TCP)
LigoWave Page 49
Figure 54 – iperf Results (UDP)
Step 6. If the result meets the requirements, before mounting PTP units outside, increase the
Transmit Power.
LigoWave Page 50
B) Resetting Unit to Factory Defaults
PTP units have the capability of being reset to defaults by pinging the device with a certain packet
size when the radio is booting. During the startup of the device, when the drivers of the ethernet
interfaces are loaded, the discovery daemon is started. The daemon suspends startup process for 3
seconds and waits for ICMP "echo request" packet of length 369 bytes. If the packet received, the
discoveryd resets the device to default configuration.
It is recommended to connect PC to the device via switch, as depending on PC OS
settings, the ARP table might be flushed during wired link status change (connecting the
device that will be reset).
Steps to reset to default settings:
Step 1. Power off the device.
Step 2. Obtain the device MAC address.
Step 3. Connect a PC to the same physical subnet as the device.
Step 4. Execute 'arp -s' command to assign the IP address (IP address should be from the
same subnet as PC) to the device MAC address:
arp -s <IP address to assign><device MAC address>
Note that syntax of MAC address differs depending on OS:
Linux OS: AA:BB:CC:DD:EE:FF
Windows OS: AA-BB-CC-DD-EE-FF
Step 5. Start pinging the device:
For Linux users: ping <IP address>-s 369
For Windows users: ping <IP address>-l 369 -t -w 0.2
Step 6. Power up device and wait about 30sec or more (depending on device hardware).
Step 7. Stop pinging the device, and let the device boot as usual. The device should start up
with factory default settings.
