OPERATING INSTRUCTIONS
4.1
GENERAL
The EM405-8 is controlled through the Ethernet interface using the TCP/IP protocol to carry a
simple command structure to the module. The carrier contains a set of software controlled
registers that allow the user to request status from the carrier, identify the carrier, and configure
the carrier. All other M/MA controls are dependent on the specific M-Module(s) that reside on
the carrier.
The EM405-8 is LXI compliant, which provides standard Ethernet I/O communication. The
Ethernet interface must be properly configured to work on the user’s network. The flexibility of
the EM405-8’s Ethernet interface allows it to be used in a large number of possible network
configurations. The unit is delivered with a default configuration that may or may not be
appropriate for the user’s network. It is up to the user and the user’s network administrator to
use the information provided throughout this section to determine what configuration is best for
the given network.
4.2
DISCOVERY
As required by the LXI specification, the EM405-8 supports the VXI-11 protocol for device
discovery and communication. This allows any VXI-11 based discovery utility to discover the
EM405-8 on the user’s network without the requirement of knowing the EM405-8’s current IP
address. VXI-11 discovery utilities are generally included with the VISA I/O library package
provided by several third-party vendors.
The EM405-8 allows for one network link per installed M-Module, plus one network link for the
carrier itself. Therefore, it is likely that the discovery utility will discover several instruments at
the same IP address. For example, if the carrier is fully populated with 8 M-Modules, the device
discovery utility may discover 9 instruments at the IP address of the EM405-8.
4.3
WEB SERVER
To use the EM405-8’s web interface, open a web page at the device’s IP address. This can be
done using any W3C compliant browser, such as Windows Internet Explorer or Mozilla Firefox.
Enter the IP address as:
x.x.x.x (i.e. 192.168.1.225)
The first (Home) page provides instrument details such as the instrument model, manufacturer,
serial number, description, LXI class, LXI compliance level, hostname, MAC address, TCP/IP
address, and firmware revision, as shown in Figure 8. The Home page also allows you to find
the physical device associated with a particular IP address by clicking the Device Identify button.
During identification, the LAN Status indicator on the front panel of the EM405-8 will blink
rapidly. The indicator will continue to blink until the Stop Identifying button is pressed.
From the Home page, the LAN configuration and Status/Control pages can be accessed using the
links in the navigation menu. These pages are discussed later.
