A TECHNICAL INFORMATION
A.1 Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the Liberator-
V1000. It covers various aspects of installation and network setup.
V1000. It covers various aspects of installation and network setup.
Note: Each of the following points must be checked at both ends of the link. Start by
running the entire procedure on one side (e.g. Terminal A). If this does not solve the
problem, repeat all the steps at the opposite terminal.

A.1.1 Power and network connection
You must verify that the terminal is connected to the power. The PoE injector must be installed and plugged in. Go
to the terminal, disconnect the RJ-45 connector and verify if there is power in the cable using a PoE++ tester.
Take the cable and plug it into a notebook or a network testing device and verify that there is a valid network
connection. If there is any problem, please replace the cable and validate the connection again.

A.1.2 Network configuration
Check that the PC
’s IP address is in the same range and subnet as the Liberator-V1000.
Note: The default IP address of the Liberator-V1000 is 192.168.0.21 and 192.168.0.22 for terminal A and B
respectively. All terminals on the network must have a unique IP address in the same range, e.g. 192.168.0.X. Any
terminal with identical IP addresses will not be visible on the network. They must all also have the same subnet
mask (e.g. 255.255.255.0).
Ping the terminal to make sure that the Liberator-V1000 is responding. On a Windows PC, g
o to Start → Run →
Type “Command” → Type “ping 192.168.0.21/22”. A successful ping will generate four replies. As soon as the
network configuration is correct you can access the GUI (Graphical User Interface) and check the settings
according to section 4.9.

A.1.3 Misalignment
On the Installation screen (see section 5.6) you see the signal strength in dBm (e.g. -30 dBm). The correct RSSI
value can be obtained from the Sub10 Systems Link Availability Calculator. If the value is more than 5dB below
below the Link Availability Calculator value, then the antenna is not properly aligned to receive the signal. You
therefore need to re-align the terminal to its opposite terminal (please follow the instructions in Section 4.8).
