Ethernet / Serial Gateway - RS485-ETH-N | 15
MAC Address:
Represents the physical address of every device that can be connected to the network. It is assigned to the
devices during production by the producing company and cannot be changed by the user. Even if they have the
same brand and model, MAC address has to be different for every device. MAC address is a 48 bit data. They
are shown in the order of hexadecimal numbers as follows:
Example: C4 : 29 : 1D : 00 : 00 : 00
IP Address:
It is the address taken within a network, by a device connected to the network. It is a form of logical addressing
but not physical addressing. With the provision that they are in different networks, there can be many devices with
the same IP address. IP addresses can be changed by the user. In IPv4 standard, IP addresses are represented
by 4 bytes. They are shown in the order of decimal numbers as follows:
Example: 192.168.35.15
Gateway Address:
Gateway is a network hardware connected to the local area network (LAN) and wide area network (WAN) at the
same time. There are different IP addresses in the local area network and wide area network. Gateway address is
the IP address of the gateway in the local area network. Data packages forwarded to this IP address are handled
in the gateway and transferred to the wide area network.

Subnet Mask:
It is used in determining whether two IP addresses are in the same network or not.
Network settings of RS485-ETH-N can be configured in two ways:
1. When “Use DHCP” is selected, RS485-ETH-N automatically receives the settings appropriate for the network
to which it connects.
2. If the IP address is to be entered by the gateway and subnet mask, “Use DHCP should not be selected and
values compatible with the network to which RS485-ETH-N connects should be entered in the appropriate
fields. Default network settings of RS485-ETH-N are as follows:
