CHAPTER 8

Advanced Use of the Analyzer – Tips and Tricks

The analyzer can then be configured to notify DynDNS.com each time the global IP address is

set or changed. When BZ-5503 or an Internet browser connects to the analyzer, it then uses a

hostname defined by DynDNS.com. From DynDNS.com it then gets the updated IP address.

You need to make an account at DynDNS.com, specifying a user name and a password for the

account and a hostname (for example, 'MyBK2250.dyndns.org') identifying your analyzer.

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 does

not 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, for example, 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 automat-

ically 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
