A computer web page browser can be used to operate the power supply through a built-in web
page server. For applications including factory and test automation, communication is made using
several standard network protocols and instrument commands.

3 SELECT THE CONTROL METHOD
3.1 Control Method Options
The power supply with the LAN option installed, may be operated through four interfaces. This
section describes how to enable each option.
MODE MODE DESCRIPTION
1 LAN Control using an Ethernet connection LAN will disable the J4-IN serial port
2 Local Control using the front panel encoders and buttons LAN can be used to measure and read
3 Serial Control using RS-232 and RS-485 through J4-IN and
J4-OUT connectors
Serial will disable the LAN port
4 Analog Control using analog signals through J1 and J3
connectors
LAN, local or serial may still be used to
measure and set protections
3.1.1 Select Local (Front Panel) Mode
The power supply may be operated in local or analog control mode even when a computer is
using the LAN connection.
When the power supply is in remote mode, the front panel “REM” LED is ON. The power supply
may be returned to local mode by pressing and releasing the “REM” button.
If the “REM” button will not go into local mode, then:
• The LAN is being used to change settings, the power supply will automatically go to remote
with every command. Stop the LAN program and then press the “REM” button.
• The LAN computer may have sent a Local Lockout command. Use the LAN to send
“SYSTem:REMote[:STAte]” (refer to Z
+
supply User Manual) or turn the power supply AC off
and on again, and then press the “REM” button.
3.1.2 Select Serial (RS-232 & RS-485) Remote Mode
The serial (RS-232 & RS-485) remote control may be selected even if the LAN option is installed.
To select the RS-232 & RS-485 mode:
1. Press “REM” button on the front panel.
2. Voltage Display will show 'INtF". Press the Voltage encoder.
3. Rotate the Current encoder to select "232 or 485" and then press the Current encoder.
3.1.3 Select LAN Remote Mode
Selecting the LAN mode will allow programming over the Ethernet cable. Any settings and
measurements may be done from a remote computer using the power supply’s built-in web
pages or using SCPI programming.
To select the LAN mode:
1. Press “REM” button on the front panel.
2. Voltage Display will show 'INtF". Press the Voltage encoder.
3. Rotate Current encoder to select "LAn" and then press the current encoder.

LAN Option Rear Panel View
The power supply rear panel, with the LAN option installed, is shown below.
1. Link LED
2. Activity LED
3. RJ-45 Socket
4. LAN Status LEDS
3.1.4 Link LED
LED embedded in the RJ-45 socket glows green when the connection is made to an active network.
3.1.5 Activity LED
Amber LED blinks when any message packets are detected.
3.1.6 LAN Status LED
There are two LED's at the bottom of the RJ-45 connector:
• Normal Operation: Steady green
The power supply has an active LAN connection
• Device Identify: Blinking green
The identify function is turned on from a remote computer using the web page or a SCPI
command. The front panel blinks along with the rear. It is used to identify one power supply
in a rack of instruments. The blinking is turned off by the web page, by sending another
SCPI command, or by changing any front panel control. In a multi-drop chain, only the
master LAN supply blinks.
• LAN Fault: Steady red
Shows the LAN mode is not enabled, the LAN connection was never made, or that the LAN
connection was made and then broken.

4 CONNECT TO NETWORK
4.1 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 power supply.
The serial link cable (0.5 m long) provided with the
Z+ power supply cannot be used for a LAN
connection.
4.2 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 server computer and network administrator to
keep it operating. The server will download the IP address and other settings to the power
supply.
2. PEER-TO-PEER NETWORK
This is typically the configuration when you connect the Z
+
power supply directly to a computer
that is not a network server. The power supply will configure its own IP address and other
settings.
Fig.4-1: Server Network Connection Diagram
Fig.4-2: Peer-to-Peer Connection Diagram
11
4.3 Power-up the LAN Power Supply
The Z+ power supply LAN option automatically detects if it is connected or disconnected from
a network. It will also automatically look for a network server and it will retrieve or create an IP
address. It will also broadcast its IP address and hostname to all other devices on the network.
1. Turn ON the power supply AC power.
“Lan” appears for about 2 seconds on the front panel display. Then “OFF” or the last output
settings will appear on the front panel display.
2. The LAN cable may be connected before or after the power supply is switched on.
3. For a server network, wait about 10 seconds.
The rear panel LAN Status LED turns green.
4. For a peer-to-peer network, wait about 20 seconds.
The rear panel LAN Status LED turns green.
When the LAN Status LED turns green, the power supply receives the IP address. It can be viewed
on the front panel. See section 5.1.
If the LAN Status LED does not turn green, refer to section 12 for troubleshooting steps.
4.4 IP Addresses
The simplest and most reliable way to open a network connection is via power supply’s IP address,
which is represented by group of four numbers separated by periods (for example: 10.1.15.123).
This IP address may be viewed from the front panel (see section 5.1).
Three modes in which the power supply can access an IP address, show below:
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 6.6.2) or
by setting the IP1-4 address on
the front panel
(see section 5.2)
Assignment Assigned by the network server Assigned by the power supply
Assigned in the “LAN Modify”
web page (see section 6.6.2) or
by setting the IP1-4 address on
the front panel
(see section 5.2)
Range Any address
169.254.xxx.xxx
Any address
Lifetime
Address may change as
the DHCP server assigns
addresses dynamically to many
instruments
Fixed for the power supply,
except if an address collision is
detected
Always fixed for the power
supply
Duplicate
Addresses
The DHCP server should
prevent duplicate IP addresses
Finds another available auto-IP
address
The LAN Status LED and Front
Panel blink.
