8.3 Configuring the 2553A Ethernet Settings
Explanation
To use the Ethernet interface, you must specify TCP/IP settings.
DHCP
DHCP is a protocol that temporarily allocates necessary information to a device so that it can connect
to the Internet.
ON
If you are connecting the 2553A to a network with a DHCP server, you can turn on the DHCP
setting. If you do, the IP address will be automatically assigned to the 2553A when it is connected to
the network, so you do not have to set the address.
OFF
If you set DHCP to OFF, set the appropriate IP address, subnet mask, and default gateway for your
network.
IP Address, Subnet Mask, and Default Gateway
The 2553A displays the IP address, subnet mask, and default gateway in the following manner.

MAC Address
The MAC address is a unique ID number assigned to an Ethernet card installed in a device. It is 12
characters long, with each character ranging from a to f and 0 to 9. MAC addresses are expressed in
octets in hexadecimal notation.
If the MAC address is 00.00.12.34.56.78, the 2553A displays it in three groups: 00.00, 12.34, and
56.78.
Note
Only use a single communication interface: USB, GP-IB, or Ethernet. If you send commands simultaneously
from more than one communication interface, the 2553A will not execute the commands properly.
