Cable preparation:
Step 1.
Peel STP service cable
and prepare “RJ-45”
connector parts.
Use RJ-45 connector
without grounding here
(RJ-45 connector with
grounding should be
used for connecting
service cable to IDU).
Step 2.
Stick rubber filler –5 on
the Part 4, previously
having removed
protective white layer
from rubber filler -5.
Insert Part 2 inside part 4
up to the stop. Part 2
must be entirely within
Part 4.

10. Your device has a factory configuration. Default login is altai, default password is
wag. Once this is done, you will see CLI (Command Line Interface). See Figure 8
Figure 8. “Login” screen
11. In order for your unit to be accessible from your LAN/PC/Laptop via Ethernet, you
should configure eth0 interface IP-address so the unit would allocate in the
desired LAN (or accessible from your PC/Laptop Ethernet adapter). You can
change this IP-address via “ifc eth0” command as shown on figure 9. After
changing the IP-address, save the configuration using “co sa” command. In the
example given the IP-address being assigned to eth0 interface is 9.1.8.1 with
mask length 24 (255.255.255.0). In order to check whether your changes were
correct, use “co sh ifc” command which shows configuration for all interfaces of
the unit. Do not forget to save your configuration using “co sa” (config save)
command.

12. If all your settings are correct you can connect the unit to your LAN using UTP
cable with RJ-45 connectors (Ethernet port of the unit is located on IDU).
To access the unit via Ethernet:
If your PC/Laptop does not have a COM-port or you want to plug the unit to the LAN
switch you can configure it using Telnet protocol.
The default IP-address assigned to the eth0 interface of the unit is 192.168.1.20 with
255.255.255.0 mask.
If you connect the unit directly to the LAN/PC/Laptop you should either change the
IP-address on the Ethernet adaptor or create an alias IP-address which would be
located in 192.168.1.0/24 network.
Connect the unit to LAN/PC/Laptop using UTP cable with RJ-45 connectors.
The procedure is the following:
1. Open the Control Panel in Windows. See Figure 10
Figure 10. Open Control Panel
2. Open “Network connections” icon. See Figure 11

6. If you are in a LAN and you do not want to change your primary IP-address so
you could keep LAN connectivity, you can assign an alias. In order to do that,
press “Advanced…” button (Figure 14). In “Advanced TCP/IP Settings” click
“Add” and put alias IP-address and mask (e.g. “192.168.1.2” and “255.255.255.0”
correspondingly). See Figure 15. Click OK in all windows opened in the described
procedure.

7. Run “Telnet” utility using “Start->Run” and type “telnet IP-address” where IP-
address is the unit’s IP-address (by default: 192.168.1.20).
3. Configure
To configure via web page:
To connect to the device via Web-browser type: http://<device IP-address> (by
default: http://192.168.1.20).
You can also make an SSL-secured connection: https://<device IP-address> (by
default: https://192.168.1.20).
For complete Web-interface configuration and user guide please see B5 Wireless
Bridge Configuration Manual.
To configure via command line:
For simplest configuration in
bridge mode type:
mint <RF IFNAME> start (ex. mint
rf4.0 start)
switch group 1 add eth0 rf4.0
switch group 1 start
switch admin-group 1
switch start
Check connectivity
Type command: mint map
If there are active nodes in the command output then you have the connection:
To change IP on Ethernet interface:
Type: ifc eth0 <IP address>/<Net
Mask> #This will add IP address as a
new alias.
Type: ifc eth0 <IP address>/<Net
Mask> -alias #This will delete IP
address.

Color indication of «mint map»command output:
Common color identifies neighbor nodes that have acceptable characteristics of a
link to the current node.
Yellow color identifies neighbor nodes that potentially may have problems with
sustainability and quality of a link to the current node. In this case link quality can be
improved through the change of certain parameters (for example, lowering bitrates).
Yellow color with red background identifies neighbor nodes that have unsatisfactory
characteristics of a link to the current node. For example, neighbor nodes that have
low characteristics of a link on the lowest possible bitrate or have errors are marked
this way. In this case link quality can be improved by such actions as antenna
alignment, cable connectivity testing and so on.
Muffer utility
Type: muffer stat
Muffer can be used for statistics gathering for estimating link load intensity and per
client.

Figure 18. Muffer Stat
The following decisions can be made by analyzing the outputted parameters:
If the number of repeated packets is comparable with total number of packets that
means that you might have an interference source on the selected frequency. For
normally operating link the percentage of repeated packets should not exceed 10%.
It is extremely important to obtain a permanent zero value for the average number
of repeats per packet. If the value is not zero that means that the link is NOT working
properly and requires further improvement
If total percentage of repeated packets and the percentage of packets that were
repeated at least once are close to each other that might mean that you have got
a permanent source of interference. Otherwise, it means that a strong interference
source appears from time to time breaking your signal
Concerning the fact that statistics module outputs the information for each MAC-
address separately, you can reveal the problem for some specific unit on the
wireless network
Load meter.
Type: loadm –l <IFNAME> (for example, loadm –l rf4.0)
Load meter is a tool to perform the channel load monitoring. It allows estimating the
load of a system interfaces specified by interface parameter.

Useful commands that should be remembered:
“help” –lists all available commands in the unit
“config show” (or “co sh” for short) – shows unit’s current configuration
“config save” (or “co sa” for short) – saves unit’s current configuration
“restart y” –immediate unit reboot. Reboot lasts for 20-30 seconds (approximately)
and during this time you will not be able to control it over Telnet. “restart XX” can be
used for a postponed reboot so the unit will be rebooted in XX seconds (this is very
helpful when there is a risk of loosing a remote unit while performing risky
manipulations with configuration). “restart 0” cancels postponed reboot.
“quit” –closes current telnet session

Grounding
Antenna should be placed on the mast on the level that is at least 1 meter lower than
a mast’s top. In this case it is of big probability that the lightning strikes the mast and
not the antenna. The mast is to be grounded on the grounding contour according to
your local standards. When the lightning strikes the antenna, the current goes through
the coaxial cable which grounds ODU clamp with the mast –the mast is grounded
via the grounding contour. The direct lightning strike to the STP service cable (ODU-
IDU) is partially terminated on the grounded IDU case. Partial termination means that
the direct lightning strike will probably destroy an STP cable. The service cable pickups

from the electromagnetic impulses are terminated on the IDU case by the winding
shield, and further –on the IDU grounding. IDU is grounded via a three-conductor
power cord and a plug containing a ground. The data & power wires pickups are
terminated via IDU protection scheme (three-conductor power cord and a plug
containing a ground).
Antenna pole, tower, ODU and lightning arrestor should be connected to
the first common grounding contour. Cable thickness should be no less
than 10AWG using corrosion-steady connectors. It is highly recommended
to entrust grounding contour development to the skilled personnel.
A special attention should be paid if antenna used is not DC-shorted. In this case
additional lightning arrestor should be used between the antenna and ODU.
Suggested grounding diagram is shown on the picture below.
