3. CONNECT TO NETWORK
3.1 LAN Cable
The LAN cable must be supplied by the customer. It may be a standard straight“patch”
CAT-5 (or better) network cable or it may be a“crossover”cable where the pins are reversed
on one end. The cable type is auto-detected by the module.
3.2 Types of Networks
There are basically two types of networks that are discussed here:
1. NETWORK WITH A SERVER: this is the typical local area network with a computer
acting as a server and network administrator to keep it running.The server will assign
the IP address and other settings to the LAN module.
2. PEER-TO-PEER NETWORK: this is typically the situation when connecting the LAN
module directly to a computer that is not a network server. The LAN module will
configure its own IP address and settings.
Figure 3. Peer-to-Peer Connection
Figure 2. Server Network Connection
13

3.3 Power-up the LAN Module
The LAN module will automatically detect if it is connected to or disconnected from a
network. It will also automatically look for a network server and receive or create an IP
address. It will also broadcast its IP address and hostname to all other devices on the
network.
1. Insert the module into any slot of the HFE rack. The front panel LAN status LED will
initially be red.
2. The LAN cable may be connected before or after the module is inserted.
3. For a server network, wait about 10 seconds.
See that the front panel LAN Status LED turns green.
4. For a peer-to-peer network, wait about 60-90 seconds.
See that the front panel LAN Status LED turns green.
When the LAN Status LED turns green, the module has received an IP address.
Run the discovery tool to check the IP address received by the module.
If the LAN Status LED does not turn green, see troubleshooting section.
Note – There should be at least one HFE supply in the rack for the module to operate.
3.4 IP Address
The simplest and most reliable way to open a network connection is using the module’s IP
address.This is a group of four numbers separated by periods (for example: 10.1.15.123).
This IP address may be viewed by running the discovery tool.
There are three modes by which the module can get an IP address, as show in this table:
IP Address DHCP Auto-IP Static IP
Mode Select DHCP is default after
“LAN Reset”
Default after “LAN
Reset” if no DHCP
server is used
May be set in the “LAN Modify”
web page (see section 5.5.2)
or by SNMP.
Assignment Assigned by the
network server
Assigned by the LAN
module.
Assigned in the“LAN Modify”web
page (see section 5.5.2)
or by SNMP.
Range Any address 169.254.xxx.xxx Any address
Lifetime Address may change
as the DHCP server
assigns addresses
dynamically to many
instruments
Address may change
for the LAN module
Fixed for the LAN module
Duplicate
Addresses
The DHCP server
should prevent
duplicate IP addresses
Finds available auto-
IP address
Returns to original IP (before
change), LAN Status LED blinks.
If duplicate IP is detected at AC ON,
the IP defaults to DHCP or Auto-IP,
LAN Status LED blinks.
Table 4: Assignment of IP address by different Protocols
14

3.5 Hostname
The hostname is an address in the form of text instead of numbers (for example: HFE-
LAN-222). In order to work with the Hostname, a naming service (such as NetBIOS) must
be running in the LAN computer.
A custom hostname can be created through the web page (see section 5.5.2) or SNMP.
For example, if the hostname is changed to“TDK-LAMBDA”, a control program can send
a command to“TDK-LAMBDA”.
The Hostname can be up to 15 characters. First character must be a letter. Last character
must be a letter or digit. Intervening characters must be either a letter, digit or hyphen.
After a“LAN Reset”, the module will create a default hostname based on the model and
serial number of the module.
The default hostname is in the following format:
HFE-LAN – < last 3 digits of serial number >
Hostname DHCP, Auto and Static IP
Default Hostname HFE-LAN-nnn
Hostname Protocol Hostname by NetBIOS
Hostname on Web Pages Shows Host name on “Home”page and “LAN Configure” page
Table 5 – Host Name format in different Protocols
15

4. LAN SETUP
4.1 View the IP and MAC Addresses
When the module is running, the IP and MAC addresses can be viewed by following
these steps:
To view the IP address-
1. Run the discovery tool. It will detect the module and show its IP Address, Manufacturer
Name, Serial Number and Firmware Revision. IP address can also be read via a LAN
specific command
To view the MAC address-
1. There is a label on the cover of the module indicating the MAC address.
2. MAC address can also be seen on the “Home” page via a Web browser and can be
read via a LAN specific command.
4.2 LAN Reset
LAN reset can be done via a LAN specific command or via the front panel reset switch.
The default LAN settings are:
o DHCP enabled
o If DHCP fails to get a lease, auto-IP settings will be obtained.
o Hostname: HFE-LAN-last 3 digits of Serial Number.
o Description: TDK-LAMBDA HFE-LAN Last 3 digits of Serial Number.
o Controller Access One Client Only
o Ping Server: Enabled
o Keep-Alive 1800 Seconds (30 minutes)
o Auto-Negotiate: Automatically select network speed
o VXI-11 Discovery: Enabled
o Password: None
o mDNS: Enabled
o DNS-SD: Enabled

5. WEB PAGES
Note – All figures in the web page section are examples only.
5.1 Benefit of Web Pages
The HFE LAN web pages are useful for:
• Reading the module’s model name, revision and LAN setup information
• Configuring the LAN connection
• Programming and reading the Power Supplies condition and reading the inventory
details
5.2 Opening the HOME Page
Once the front panel LAN Status LED has turned green (see Section 1.3), you may open
the HFE LAN web page.
1. Read the IP address of the module (see section 4.1)
2. Open a web page browser program such as Internet Explorer or Chrome. Type the
module’s IP address as shown below.
The module’s Home page will appear. If it does not, see Troubleshooting section.
3. Alternately, the hostname may be used for addressing the web page as shown below
(if the module is set for “DHCP/Auto-IP”, and NetBIOS naming service is running on
the computer). See Section 3.5 for a description of the hostname
The module’s Home page will appear. If it does not, see Troubleshooting section.
17

5.3 The HOME Page
The following page appears when the web page is first opened or when it is refreshed:
VISA Name Using IP Address: For automation programming, VISA is a type of
communication driver. For LAN instruments, the IP address may be used in the VISA
resource descriptor.
VISA Name Using Hostname: For automation programming, an alternate VISA resource
descriptor using the module’s hostname. See section 3.5
Hostname: A unique name for a device on a network. The default hostname is described
in section 3.5, it is configured in section 5.5.2.
Auto-MDIX: The LAN module will automatically detect if a patch or cross-over LAN
cable is used.
Auto-Negotiate: The LAN will automatically adjust its speed to the fastest available.
