Connecting using a Switch, or Similar Device
The SierraNet M408 analyzer is automatically detected by the application if the analyzer
and the host PC on which the application is running are on the same Ethernet subnet. If
the analyzer and the host PC are located on different subnets then the IP address of the
analyzer needs to be configured manually in the application. To add the IP address to the
Select Device dialog, use the Add Device button (refer to “Add Device...” on page 18 and
see Figure 1.24 on page 19 ). See Figure 1.24 on page 19 to set the IP address.
Analyzer Connected Directly to the Host Machine Using a Crossover Ethernet Cable
SierraNet M408 Systems are designed to connect to host PCs using a network connection,
which allows the user to control the SierraNet M408 System from a local or remote host
system. When connected to the host machine using a crossover ethernet cable, the
Analyzer must be given a static IP address such that it will reside on the same subnet as
the Ethernet interface of the host computer. See Figure 1.24 on page 19 to set the IP
address.
Ethernet Connectivity Through a Different Subnet
The default discovery mechanism relies on broadcast messaging, which typically does not
traverse between different subnets. Thus, alternate mechanisms are required to discover
devices on different subnets. This section describes two methods: automatic subnet
scanning and manual device adding.
Automatic Subnet Scanning
The software can be configured to automatically discover devices on other subnets. To do
this, you must specify which subnets you would like the software to scan. This section
describes how to add subnets so that the software will scan them for available devices.
