Hand-held Analyzer 2250 Light – User Manual

In the analyzer you need to specify the Hostname, Username and Password and set Active to

Yes in Preferences, under Modem/DynDNS settings. Each time the analyzer detects a change in

the IP address it notifies DynDNS.com.

Note: To avoid too much traffic at DynDNS.com, the analyzer ensures that this service doesn't

allow updates of settings more frequently than every 10 minutes. So you may experience up to

a 10 minute wait for DynDNS settings to update.

8.3 Network Settings

The analyzer can be connected to a LAN (Local Area Network) through an Ethernet interface

or to WLAN (Wireless Local Area Network) using equipment conforming to the

IEEE 802.11a/b/g standard. This connection can be used to synchronise measurement and

setup data with a host PC using BZ-5503.

The analyzer supports TCP/IP (Transmission Control Protocol/Internet Protocol) on the LAN

and WLAN.

This requires the analyzer to have a unique address on the network. This address is called an IP

address and consists of four sets of 3-digit numbers, e.g. 010.116.121.016.

The IP address can be obtained in different ways:

• Automatically

• Using DHCP

A DHCP (Dynamic Host Configuration Protocol) Server on the network assigns

automatically an IP address to the analyzer when connected to the network. This is the

most common way of setting up IP addresses.

• Using Link-local

If no address is automatically assigned by the DHCP Server, then after a few seconds

the analyzer will use an address from the Link-local address range 169.254.x.x.

This will most likely be the case when connecting the analyzer directly to a PC using

an Ethernet Crossover cable

• Manually

You setup the IP address manually.

This will typically be the case in a private network without a DHCP Server.

8.3.1 Connecting to the Analyzer

Wired LAN Connection

• Use a “straight-through” (standard) Ethernet cable with RJ45 connectors at both ends to

connect the analyzer to the network (via a hub, switch or router).

• Use a “crossover” Ethernet cable with RJ45 connectors at both ends to connect the

analyzer directly to a PC.

Hardware version 4 has an Auto-MDIX facility, allowing you to use either a straight-through

or crossover cable to connect to a network or PC.
