address.
 Subnet Mask
The format of subnet mask is nnn.nnn.nnn.nnn, for example,
255.255.255.0. After enabling the ManualIP mode, use the up/down
direction keys to select SubMask and use the numeric keyboard to set
the desired subnet mask.
 Gateway
The format of gateway is nnn.nnn.nnn.nnn, for example, 172.16.2.1.
After enabling the ManualIP mode, use the up/down direction keys to
select Gateway and use the numeric keyboard to set the desired
gateway.
 DNS
The format of DNS address is nnn.nnn.nnn.nnn, for example,
202.96.199.133. After enabling the ManualIP mode, use the up/down
direction keys to select DNS and use the numeric keyboard to set the
desired DNS address. Generally, users do not need to set the DNS
address of the network and this parameter setting can be ignored.
3 VISAAddr
VISA (Virtual Instrument Software Architecture) is an advanced application
programming interface developed by NI (National Instruments) for
communication with various instrument buses using the same method
regardless of the type of the instrument interface (GPIB, USB, LAN/Ethernet or
RS232). The instrument communicating with it via the GPIB, USB, LAN/Ethernet
or RS232 interface is called “Resource”. The VISA address (also called VISA
descriptor) refers to the resource name and describes the accurate name and
position of the VISA resource. For example, if LAN interface is currently used for
communicating with the instrument, the VISA descriptor
is :TCPIP0::172.16.2.13::INSTR.
4 MAC
The physical address (also called MAC (Media Access Control) address or
hardware address) is used to define the position of the network device. For an
instrument, the MAC address is unique. When distributing an IP address for the
instrument, the MAC address is always used to distinguish the instrument. The
MAC address (48 bits, namely 6 bytes) is usually denoted by a six-section
hexadecimal number, for example, 00-14-0E-42-12-CF.
5 Default
In the LAN parameter setting interface, press Default to restore the network
parameters to their defaults.
6 Apply
In the LAN parameter setting interface, press Apply to configure the network
parameters using the current settings.
