4. Enter the IP address using the LAN CONFIG menu:
a. Select CONFIG > IP-ADDRESS.
b. Refer to the recorded computer's IP address (Step 1: Identify and record the existing IP configuration
(on page A-2)). A portion of the computer's IP address is used as a base for the instrument's unique ID.
Only the last three numbers (after the last decimal point) of the IP address will differ between the
computer and the instrument. If the subnet mask is 255.255.255.0, the last three digits can be any value
from 1 to 255.
For example, the Internet Protocol (TCP/IP) Properties dialog box shows that the computer's IP address
is 192.168.1.100 (see the figure titled "Internet protocol (TCP/IP) Properties dialog box" in Step 2:
Disable DHCP to use the computer's existing IP address (on page A-3)). A unique IP address for the
instrument might be 192.168.001.101.
The instrument’s IP address can have leading zeros, but the computer’s IP address cannot.
c. Use the navigation wheel to select and enter an appropriate IP address for the instrument. Be sure to
record the instrument’s IP address to use in Step 5: Access the instrument's web page (on page A-9).
d. Press ENTER key or navigation wheel to confirm the changes.
e. Press the EXIT (LOCAL) key to return to the LAN CONFIG menu.
5. Change the subnet mask from the LAN CONFIG menu:
a. Select CONFIG > SUBNETMASK, and then press the ENTER key. The SUBNETMASK menu item is to
the right of GATEWAY. Use the navigation wheel to scroll through the options.
b. Modify the SUBNETMASK value to match the computer settings recorded earlier (or
255.255.255.000 if DHCP Enabled = YES).
c. Press the ENTER key or the navigation wheel when you are finished changing all the characters.
d. Press the EXIT (LOCAL) key to return to the LAN CONFIG menu.
6. From the LAN MENU, select APPLY > YES, and then press the ENTER key.
Step 4: Install the crossover cable
Connect the supplied crossover cable between the computer's NIC card and the LAN connector on
the instrument’s rear panel. There are multiple connectors on the Series 3700A rear panel. Be sure to
connect to the LAN connection port.
