1. GENERAL INFORMATION
1.1. Introduction
The Local Area Network (LAN) option for the GenesysTM series power supply allows the
user to remotely program, measure and check status of the power supply. It uses an
Ethernet connection like those used to connect computers to each other and to the Internet
A computer’s web page browser may be used to operate the power supply through a built-
in web page server. For applications including factory and test automation, communication
may be done using several standard network protocols and instrument commands
Refer to the GenesysTM Technical Manual for information on installing the power supply,
safety requirements, specifications, connecting the power-in and out, operating the front
panel, using the serial (RS-232/485) programming and the analog (J1) programming

3. SELECT THE CONTROL METHOD
3.1. A Variety of Control Methods
The Genesys™ power supply with LAN is very flexible. In addition to the LAN, there are
other ways the supply can be used.
See the Technical Manual for Genesys™ Power Supply for more details on the local (front
panel), serial (RS-232/485), or analog (J1) control.
3.2. LAN, Local, or Serial
The power supply, with the LAN option installed, may be operated through four interfaces.
This section describes how to enable each.
MODE
MODE DESCRIPTION
1
LAN
Control using an Ethernet connection
LAN will disable the J3-IN serial port
2
Local
Control using the front panel encoders and
buttons
LAN can be used to measure and
read while in local mode
3
Serial
Control using RS-232 and RS-485
through the J3-IN and J3-OUT connectors
Serial will disable the LAN port
4
Analog
Control using an analog signals to the
25-pin ‘J1’ connector
LAN, local or serial may still be used
to measure and set protections
3.2.1. Select Local (Front Panel) Mode
The supply may be operated in the local, or front panel, mode even when a computer
is using the LAN connection.
If the supply is in remote mode, the front panel “REM/LOC” LED is ON. The supply
may be returned to local by pressing and releasing the “REM/LOC” button
If the “REM/LOC” button will not go into local mode, then:
If a LAN program is running to change the power supply settings, it will
automatically go to remote with every command. Stop the LAN program and then
press the “REM/LOC” button.
The supply may be set to Local Lockout. Use the LAN to send SYST:SET LOC
(see section 11.4.2) or turn the supply AC off and on and then press the
“REM/LOC” button.
3.2.2. Select RS-232 & RS-485 (Serial) Remote Mode
The serial (RS-232 & RS-485) remote control may be selected even if the LAN option
is installed. The serial remote is described in the Technical Manual for the Genesys™
Power Supply. The LAN has similar capabilities as the serial remote, but the LAN
SCPI programming language is not compatible with the serial language.
To select the RS-232 & RS-485 mode:
A. Switch the supply AC power off.
B. Set the LAN card switches pin1 and 2 to DOWN (see Figure 3).
C. For RS-232, set rear-panel SW1 pin 6 to DOWN.
For RS-485, set SW1 pin 6 to UP.
D. Switch the supply AC power on. The front panel will not show “Lan” at startup.

10
8303460000 Rev A IA672-04-01-Rev. I
3.2.3. 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:
A. Switch the supply AC power off.
B. Set the LAN card switch pin1 to UP (see Figure 3). Pin 2 must stay DOWN.
C. Switch the supply AC power on. The front panel will show “Lan” at startup.
3.3. LAN Option Rear Panel View
The power supply rear panel, with the LAN option installed, is shown below.
Figure 3. Rear Panel LAN Features
3.3.1. LAN Enable Switch: This two-pole DIP switch allows you to select the LAN or the
RS-232/485 mode. The switch on the right must stay set down.
Note
The supply’s AC power must be OFF to change this switch. The
change is only detected during the supply’s power-up sequence
SWITCH UP: select the LAN mode. The power supply shows “Lan” at power-up.
The rear panel J3-IN port for RS-232/485 does not operate. The J3-OUT port may be
used to start a multi-drop chain of supplies (see section 12).
Note
When using the LAN, always set the supply to RS-232 mode by
setting rear panel SW6 bit 6 to DOWN. See section 12.2 for details
SWITCH DOWN: select the RS-232/485 mode. The power supply does not show
“Lan” at power-up. The rear panel J3 ports for RS-232 and RS-485 do operate. The
power supply may be used in a chain of multi-drop supplies (see section 12). See the
Technical Manual for the Genesys™ Power Supply for the description of the
RS-232/485 mode.

3.3.2. Link and Activity LED: this small LED, embedded in the RJ-45 socket, glows green
when the connection is made to an active network and it blinks when any message
packets are detected.
3.3.3. Collision LED: this small LED, embedded in the RJ-45 socket, blinks green when
the LAN packets are corrupted by collisions.
3.3.4. LAN Status LEDs: These are a red LED (top) and a green LED (bottom) to the right
of the RJ-45 connector. They show:
Normal Operation: Steady green LED. The power supply has an active LAN
connection.
Device Identify: Blinking green or red. 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 the ‘blink off’
SCPI command, or by changing any front panel control.
In a multi-drop chain of supplies, only the master LAN supply can blink.
LAN Fault: Steady red LED. Shows the LAN mode is not enabled, the LAN
connection was never made, or that the LAN connection was made and then
broken.

8303460000 Rev A IA672-04-01-Rev. I
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.
Note
The serial link cable (0.5 m long) provided with the Genesys™
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:
B. NETWORK WITH A SERVER: this is the typical local area network with a server
computer and network administrator to keep it running. The server will download the
IP address and other settings to the power supply
Figure 4. Server Network Connection Diagram

13
8303460000 Rev A IA672-04-01-Rev. I
B. PEER-TO-PEER NETWORK: this is typically the situation when you connect the
Genesys™ supply directly to a computer that is not a network server. The power
supply will configure its own IP address and other settings.
Figure 5. Peer-to-Peer Connection Diagram
4.3. Power-up the LAN Power Supply
The Genesys™ power supply LAN option will automatically detect if it is connected or
disconnected from a network. It will also automatically look for a network server and it will
get or create an IP address. It will also broadcast its IP address and hostname to all other
devices on the network.
A. Before turning the power supply ON, verify it is set to enable LAN. See the switch
setting in section 3.3.1.
B. Turn ON the power supply AC power. See the front panel show “Lan” for about
3 seconds. After that, the supply will show “OFF” or the last output settings.
C. The LAN cable may be connected before or after the supply is switched on.
D. For a DHCP server or STATIC IP network, wait about 15 seconds.
See the rear panel LAN Status LED turns green.
E. For a peer-to-peer network, wait about 40 seconds.
See the rear panel LAN Status LED turns green.
The computer screen may show a LAN notification, “This connection has limited or no
connectivity.”
When the LAN Status LED turns green, the power supply IP address will change from all
zeroes to a valid address. It can be viewed on the front panel (see section 5.1).
Note
If the LAN Status LED does not turn green,
see section 15 for troubleshooting steps.

14
8303460000 Rev A IA672-04-01-Rev. I
4.4. IP Addresses
The simplest and most reliable way to open a network connection is with the power
supply’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 from its front panel (see section 5.1).
There are three modes which the power supply can get an IP address, as show in this
table:
Note: Static IP numbers (octets) may not be set to zero when setting from the front panel,
but they may be set to zero when using the web page.
4.5. Hostnames
The hostname is a way to address the supply using a name instead of an IP address.
The power supply’s hostname can be seen on its web Home page. Using the hostname
requires a network with naming service such as NetBIOS or DNS.
The factory default hostname is in the format:
< Product > < Voltage or Current rating > –< last 3 digits of serial number >
The default hostname will use the larger number from the voltage or current rating and then
append a Vor A. The last three digits of the serial number will skip over any letters.
Example factory default hostnames:
Model
Serial Number
Default Hostname
GEN8-180-LAN
08J4210B
GEN180A-210
GEN600-2.6-LAN

8303460000 Rev A IA672-04-01-Rev. I
A custom hostname can be created through the web pages (see section 6.6.2). For
example, the hostname can be changed to Heater_3.
Hostname Conflict: The power supply can detect if its hostname is already used by
another device. This is called a hostname conflict. In this case, the supply will make its
name unique by appending a dash and number to it. For example, it will become
Heater_3-2.
A LAN Reset (see sections 5.3 and 5.4) will not change the hostname, even if it is a custom
name, but it may remove the dash number if a hostname conflict has been removed.
To restore the factory default hostname, open the LAN Modify web page and enter a
blank for the new hostname (see section 6.6.2) or send the DIAG:COMM:LAN:FAC
command (see section 11.6.6).
The power supply may be set to one of three network modes in the table below:

4.6. Description and DNS Service Names
On the power supply web page, the Description field is also the DNS-SD service name.
The service name may be used by a network running the DNS-SD protocol (also called the
‘Bonjour’ discovery protocol).
The factory default description is “Genesys DC Power” plus:
< Product > < Voltage or Current rating >
The default description will use the larger number from the voltage or current rating and
then append a Vor A. This is similar to the hostname, but without the serial number.
Example: Genesys DC Power GEN1250V
A custom service name can be created through the web pages (see section 6.6.2). For
example, the service name can be changed to AuxMixer.
Service Name Conflict: The power supply can detect if the service name is already used
by another device. This is called a service name conflict. In this case, the supply will make
its name unique by appending parenthesis and number to it. For example, it will become
AuxMixer (2).
To restore the factory default description, open the LAN Modify web page and enter
a blank for the new description (see section 6.6.2) or send the DIAG:COMM:LAN:FAC

5. LAN SETUP
5.1. View the IP and MAC Addresses
When the power supply is running with the LAN enabled, the IP and MAC addresses may
be viewed on the front panel by following these steps:
A. Press and hold the FOLD button for three seconds. The 7-segment displays will show
something such as:
IP-1 010
By turning the voltage encoder, the complete IP and MAC addresses may be seen.
All four numbers of the IP address may be changed through the web pages or from the
front panel (see next section). The MAC address cannot be changed.
The IP may not show on display if faults, such as Enable or Shut-Off, are in progress.
IP-1 10 In this example,
Rotate voltage knob IP-2 225
IP-3 26 –the IP address is:
IP-4 38 10.225.26.38
AC-1 00
AC-2 19 –the MAC address is:
AC-3 F9 00:19:F9:27:D3:B0
AC-4 27 (“AC” is short for “MAC”)
AC-5 d3
AC-6 b0
B. If the voltage knob is not changed for five seconds, the supply will revert to the normal
voltage and current displays. If this happens, press and hold the FOLD button again.
5.2. Change the IP Address
The LAN with revision after 2.0 allows you change all four numbers (octets) of the IP
address from the front panel. The IP address has four numbers (ex: “192.168.53.44”).
Each number may be set to any value from 1 to 254.
The power supply must be set to Local Mode to allow changing the IP address.
See section 3.2.1 to set local mode.
A. Press and hold the FOLD button for three seconds. The 7-segment displays will show
something such as:
IP-1 192 “192” is the 1st number in the address.
B. Rotate the voltage encoder until the display shows something such as:
IP-3 53 “53” is the 3dnumber in the address.
C. Rotate the current encoder to change the 3d number in the address:
IP-3 60 “60” is the new 3dnumber.

D. To apply the new address, momentarily press the “FOLD” button.
See the display shows for a few seconds:
LAn Hold
This shows the LAN connection is on hold while acquiring the new address.
If you do not press “FOLD” soon enough, the display returns to normal and the old
address is kept.
If another device already has the address you are trying to set (duplicate
addresses), then after “Lan Hold” clears, the front panel will blink and the address
will return to what it was before the change was made.
Note
When you change the IP address from the front panel,
the Genesys™ LAN will switch to STATIC addressing.
( DHCP and Auto-IP addressing will be disabled)
5.3. LAN Reset
If it is necessary to reset the supply to the factory default LAN settings, use the front panel
to:
A. Press and hold the OVP/UVL button for 2 seconds.
B. The 7-segment displays will show:
LAn rES
C. Release the OVP/UVL button
D. Briefly pressed and release the OVP/UVL button again.
E. The displays will briefly show:
rES 0000
and the LAN will be reset to the default settings (listed below).
If the OVP/UVL button is not pressed again, the LAN settings will not be reset.
F. It may be required to AC cycle the power supply off and on. This ensures a new
network connection is established with the reset values.
In addition the DIAG:COMM:LAN:RES command may be sent to reset the LAN.
See section 11.6.6.
This display may not show if faults, such as
Enable or Shut-Off, are in progress

6. WEB PAGES
6.1. Benefit of Web Pages
The GenesysTM web pages are useful for:
Reading the supply’s model, identity, revision and LAN setup information
Configuring the LAN connection
Programming and reading the supply’s DC output
This is all done graphically. There are no commands to look up
6.2. Opening the HOME Page
Once the rear panel LAN Status LED has turned green (see Section 3.3.4), you may open
the GenesysTM web page
A. Read the IP address from the supply’s front panel by holding the FOLD button (see
section 5.1 for details)
B. Open a web page browser program such as Internet Explorer or Netscape Navigator.
Type the power supply’s IP address as shown below. Click the GO button
The power supply’s Home page will appear.
If it does not, see Troubleshooting section 15.
C. Alternately, the hostname may then be used for addressing the web page as shown
below (if the power supply is set for “DHCP/Auto-IP”, and if a DNS naming service is
running on the computer). See Section 4.5 for a description of the hostname
The power supply’s Home page will appear. If it does not, see Troubleshooting section 15
