1.1. IP Network and Address
The IP networks the NX-100 and NX-100S can use include Local Area Networks (LAN) used in small-scale
areas, such as within or on the premises of a company, and the Internet, which covers a wide area over
remote distances.

LAN
LANs differ from the Internet in the IP address to be used.
Local IP address (private IP address): This address is used and can be freely set within the LAN.
Global IP address: This is the only address that is used to access the Internet.
To use the NX-100 and NX-100S units through the Internet, fixed
global IP addresses must be acquired and assigned to them or the
router if it is used.
When a connection is made from Unit B to Unit A in the figure, the local address can be used. However, when
a connection is made from Unit C to Unit A, the global IP address must be used.
The fixed global IP address must be assigned to the units connected via the Internet.
When selecting an NX-100 or NX-100S which is connected through the Internet as the "target connection unit"
for a broadcast pattern, contact or serial bridge* in NX-100 or NX-100S unit setting, the fixed global IP
address must be designated.
Consult with network management personnel or the ISP (Internet service provider) concerning the acquisition
of a fixed global IP address.
* The serial bridge function is valid only for the NX-100.
