Q.3 What is a Subnet mask ?
A
An IP address is made up of the network address to which the computer belongs (network
address) and the computer’s own address within the network (host address). The Subnet
mask determines the division between these.

The Subnet mask, similar to the IP address, is made up of four blocks of numbers divided
by periods, such as “255.255.255.0”.
This number is absolutely necessary to enable participation in a network, so it is necessary
to set the Subnet mask to a number that suits your network environment.
Q.4 How should I make settings for the IP address / Subnet mask ?
A
The IP address and Subnet mask settings vary depending upon your networking
environment (structure). Please consult your network administrator for details. Below is a
simplifi ed explanation of a company LAN set up for your reference.
If the computer connected to your company LAN has a Subnet mask of "255.255.255.0"
and an IP address of "192.168.100.1", set the Subnet mask to the same as your computer,
"255.255.255.0".
Set the IP address to 192.168.100.***. Make sure to set the last three digits,***, to a number
between 1-254 that is not the same as any other computer connected in your network.

Q.5 What is a MAC address ?
A
A MAC address is a unique number made up of alphabet and numbers that is assigned
separately to the components of network communication (computer, server, router, etc…).
Each MAC address is assigned to the hardware and is unique to that device, so there is no
chance for duplication.
If you compared it to a cell phone, even though the phone number may be changed,
you could think of the MAC address as the serial number of the phone, which cannot be
changed and is unique to each unit.
The MAC address is written on a sticker on the back of each TR-7W logger.
