LAN Status Indicator

The lower icon notes the two status LEDs located at the bottom of the LAN port.

If neither of the LEDs is lit, the network is not connected.

• position 1: when lit, it indicates that the LAN port is connected.

• Position 2: When flashing, it indicates that the LAN port is receiving or

sending a message.

Configure LAN Interface Information

By default, DHCP is on, which may enable communication over LAN. The

letters DHCP stands for Dynamic Host Configuration Protocol, a protocol for

assigning dynamic IP addresses to devices on a network. With dynamic

addressing, a device can have a different IP address every time it connects to

the network. The user can view the related information of LAN interface or

configure the communication parameters in system menu.

• Automatically configure the address of the instrument.(Auto)

When selected, the instrument will first try to obtain an IP address from a

DHCP server. If a DHCP server is found, the DHCP server will assign an IP

address, Subnet Mask, and Default Gateway to the instrument. If a DHCP

server is unavailable, the instrument will try to obtain an IP address using

AutoIP. AutoIP automatically assigns an IP address, Subnet Mask, and

Default Gateway addresses on networks that do not have a DHCP server.

• Manually configure the address of the instrument.(Manual)

Set the following parameter. The following information only appear when

Manual is selected.

– IP Addr: This value is the Internet Protocol (IP) address of the

instrument. An IP address is required for all IP and TCP/IP

communications with the instrument. An IP Address consists of 4

decimal numbers separated by periods. Each decimal number ranges

from 0 through 255 with no leading zeros (for example, 169.254.2.20).

If neither of the LEDs is lit, the network is not connected.

♦ position 1: when lit, it indicates that the LAN port is connected.

♦ Position 2: When flashing, it indicates that the LAN port is

receiving or sending a message.

– Sub Net: This value is used to enable the instrument to determine if a

client IP address is on the same local subnet. The same numbering
