fitted for safety reasons. The EMP Protector should be professionally fitted as per the
manufacturer’s instructions. These instructions come with the EMP Protector.
Observe all local regulations on the fitting, grounding and specification of lightning or
surge arrestors on the antenna cable.
Disconnect or switch off in-line equipment when installing, checking, disconnecting
and connecting EMP protectors. This includes also the exchange of gas discharge

Paragon-neo Getting Started Guide Page 11 of 21
tubes. Keep back from such activities during thunderstorms. Be aware that only a
complete protection system according to IEC 62305-1 can protect your equipment
and personnel against the impact of lightning.
This includes an external lightning protection system with air terminal, down
conductor and grounding system and bonding of all incoming and outgoing lines
(e.g. protectors for mains, data and telephone lines) - not RF lines only.
With gas discharge tube protectors take care that the GDT has been properly
installed before putting the equipment into operation.

Paragon-neo Getting Started Guide Page 13 of 21
Configuring your Computer
Depending on which Microsoft operating system is running on your computer (Windows 8 or
Windows 10), you must modify the computer network settings as described in the following
sections.
To control the Paragon-neo over a networked connection, the recommended approach is to
connect the Paragon-neo directly to the network. Ensure that you understand the IP address range
used in that network and any associated subnet mask and default gateway addressing
requirements. If in doubt, contact the network’s System Administrator for the appropriate
addresses.
Microsoft Windows 7
1. Click on Start > Control Panel > Network and Internet > Network and Sharing Center then
Change Adapter Settings.
2. Right-click Local Area Connection > Properties.
3. Click on Internet Protocol Version 4 (TCP/IPv4) > Properties.
4. Click on Use the following IP address and enter an IP address, Subnet mask and Default
gateway. The IP address used should be different from the Paragon-X IP address (shown on its
display) only in the last 3 digits e.g. for a Paragon-X IP address of 192.168.3.100 a suitable host
PC IP address would be 192.168.3.105. This ensures Paragon-X will have an IP address on the
same subnet as the host PC.
Microsoft Windows 10
1. Open the Windows Start Menu, then type Connections in the search box and select the View
Network Connections item from the resulting list in the Settings subsection.
2. In the window which will now be displayed, right-click on the Local Area Connection icon for the
adapter to which Paragon-X is connected and click the Properties item (this may require
Administrator credentials to be supplied, depending on the user type configured).
3. Click on Internet Protocol Version 4 (TCP/IPv4) then the Properties button.
4. Click on Use the following IP address and enter an IP address, Subnet mask and Default
gateway. The IP address used should be different from the Paragon-X IP address (shown on its
display) only in the last 3 digits e.g. for a Paragon-X IP address of 192.168.3.100 a suitable host
PC IP address would be 192.168.3.105. This ensures Paragon-X will have an IP address on the
same subnet as the host PC.
