Product Features
Congratulations on selecting this smart, web enabled DC power
switch. Features include:
Simple Web Interface
The internal web server is accessible from any browser. Simply
enter an IP. Conguration and control are web-based. A RESTful
API is provided in addition to traditional HTTP controls.
AutoPing™ Reboot
AutoPing continuously monitors an IP address. If a server, router,
radio or other peripheral goes down, AutoPing can automatically
reboot it without user intervention. AutoPing can monitor several
devices and multiple IPs simultaneously.
Dual 50A inputs, 32 Switched DC 3A Outputs
Two input busses A&B are provided with separate 50A input
breakers. Outputs 1-16 are powered from bus A. Ouputs 17-32
are powered from bus B. On each output, a self-restetting PTC
protects against overcurrent.
Programmable LCD Display & Keypad
A 2x16 LCD displays status for each outlet. Custom messages
can be displayed via user scripts A keypad adds local control.
Multi-User Password Security
Multi-user authentication limits access. The administrator selects
which relays each user can control.
Sequenced “On Timer”
A programmable delay timer switches circuits on in sequence,
rather than simultaneously. Most devices draw a surge of power
when initially switched on. Using this timer, more equipment
can share a single circuit without overloads due to startup surge
current. Lua scripts can be used to create customized power-up
and shut-down sequences with variable timing.

Quick Setup
Use these shortcuts if you are an experienced installer. We
recommend reading the entire manual for rst-time installation.
• Unpack. Save the carton. Attach the line cord. Connect power
and loads. The switch can be installed “high side” or “low side”.
Inputs can be positive or negative. Returns are bonded together.
• Attach an Ethernet cable from the controller to your LAN. Switch
power on. If you are attached through a switch, you may need to
power-cycle your switch to initially establish a connection.
• Ping the default address 192.168.0.100 to conrm that a
network connection is established. If you don’t receive a response,
proceed to the IP Setup section below.
• Log in to the switch using the default user name admin and the
password 1234 Note: “admin” must be entered in lower case.
• Click the Settings link to reach the conguration page. Select
the safest power-loss conguration for your installation: (all OFF,
all sequential ON, or pre-powerloss sequential ON) Note that pre-
powerloss means the last previously congured state, and it does
not take cycling into account. “Power loss” means <10.5V DC
power for more than 100ms on both the A & B bus simultaneously
• Congure the switch as described below. After each change,
click Submit and wait for the page to refresh before continuing.
Tip: A digital meter is handy for checking conguration and
actual current drains.

IP Setup
If your network settings won’t access the default IP, use a direct
cable connection (temporarily bypass any switch or router)
and follow these steps to add a compatible static IP, such as
192.168.0.50 Before adding an IP, close all programs and
browsers. After the link is established, you can enable DHCP.
Windows Step 1
In Windows, the rst step is locating the network adapter TCP/IP
properties. The procedure diers for each Windows version:
Windows XP, 2000, 2003: Open Start / Control Panel / Network
Connections. In “classic view”, select Start / Settings / Control
Panel /Network Connections. Right-click on Local Area
Network Connection and select Properties. Proceed to step 2.
Windows Vista: Open Start, right click on Network, then on
properties. Double click Network and Sharing Center, click
Manage Newtork Connections. A Network Connections window
appears. Right click on the network connection to the switch, ie.
Local Area Network. Proceed to step 2.
Windows 7: Open the Start orb, click on Control Panel. Click
View Network Status and Tasks, then Change Adapter
Settings. Proceed to step 2.
Windows 8-10: Right-click on the Windows Start button. Select
Control Panel. Select Network and Sharing Center or Network-
>Network Settings. Click Change Adapter Settings or Adapter
Options. Right click on your connected network and select
Properties. Proceed to step 2.
Windows Step 2
The second step is adding an IP such as 192.168.0.50
Temporarily disable DHCP while conguring the switch.

Click Apply and
close windows.
Ping to conrm the
connection.
Point your browser to 192.168.0.100 Log in. Detailed instructions
are at digital-loggers.com/ip_setup
Mac OS X
Turn AirPort o temporarily. Click the Apple logo, then System
Preferences, then Network. Select Built-In Ethernet and then
Congure. Under the TCP/IP tab, select Manually and enter an IP
address such as 192.168.0.0 as shown:

Network Conguration
HTTPS is disabled by default. WiFi is enabled with a random
key. Start by establishing a hard-wired network connection to
32-Port DC Smart Switch

192.168.0.100, or use the LCD and keypad to display the default
WiFi SSID and password. The Settings page controls network
conguration:
The IP address of the controller needs to match the “class C” of
your system. In other words, the rst three bytes (192.168.0) must
match the IP on your computer to access the Pro. Using a ping
utility is a good way to conrm a valid network conguration. An
“unreachable” report from Ping indicates miscongured network
settings.
Once you have a connection, the switch may be operated via a
web browser. To access the Pro, enter the IP address in the URL
eld of your web browser. The default is http://192.168.0.100 SSH
is disabled by default.
After setup, the HTTP and SSH ports (if enabled) may be moved
to improve security. For example, changing the HTTP port to
2015 requires a browser URL of 192.168.0.100:2015 to reach the
switch. Note that some browsers will deny connections to
ports under 1024.

Home (Outlet Control) Page
To access the home page, rst enter the controller’s IP address in
the browser URL eld, then log in. User admin has access to all
features. Other users have limited access to circuits as assigned
by the administrator.
Relay Control
Clicking “Relay Control” links to the home page used for manually
switching circuits on and o. Access to specic circuits is
determined by user-name. Admin controls all circuits.
Setup
The setup page lets you set outlet names, create web links, adjust
startup delays, and set a power loss recovery mode. You can also
add user accounts and change login credentials on this page.
Scripting
The Lua language lets you easily customize the switch. Scripts
may be started manually, automatically on power-up, by external
http commands, or by AutoPing events. Find a list of commands
and examples at: digital-loggers.com/scripts.html
AutoPing
The AutoPing page lets you set parameters to automatically
32-Port DC Smart Switch

reboot attached equipment. First, specify an IP address to ping.
Next, adjust the timing settings and use the checkboxes to link the
IP to power circuits. For example, if a router is unreachable, you
may choose to automatically reboot both a router and a switch
attached to two dierent circuits. Learn more on page 13 and at
digital-loggers.com/AutoPing
System Log
The switch keeps internal event logs including logins, outlet
switching, errors, and AutoPing events. Recent events are stored
in the log and accessible from the System Log page. SYSLOG
export is supported. More information: digital-loggers.com/syslog.

Logout
Browser logout is automatic when a session is closed or after a
time-out period. Use this link to log-out in advance.
Programmable Web Links
User-dened web links are provided. Set names and destination
URLs for these links on the Settings page. These are convenient
for connecting to other power controllers, linking to page hosted
elsewhere, and for starting scripts.
Switching Circuits On and O
The relay control page lets you control any circuit. The master
control lets permitted users switch all circuits on or o.
To switch a circuit, simply click to the right of the relay name or
number. On->O switching is immediate O->On switching speed
is limited by the adjustable On Sequence Delay setting.
Use the keypad for local control: Select an outlet using the
arrow keys, then press on, o, or cycle. Press ON or OFF for 5
seconds to lock or unlock an outlet. Locking prevents web access.
To change the display mode, press the up and down arrows
simultaneously. The keypad may be disabled on the Setup page.
You may also want to Cycle an attached device. This feature is

useful for rebooting Ethernet devices which may interrupt the
web link to the switch. Clicking Cycle switches power o, waits
for the Cycle time, and then switches power back on while
conforming to the ON Sequence Delay. This can be used to
restore connectivity).
You can also cycle all relays using the Master Control on the
bottom of the page. An adjustable ON sequence
delay takes eect when relays are turned on one
after another, ehether when using the button, on
power-up, or when switching manually using the
front panel. This prevents power surges. A
separate Cycle delay setting is provided on the
setup page.
Depending on your web browser settings, you may need to click
the Refresh button or F5 key to update the on-screen status
display after changing settings. Screen refresh rate is adjusted
in two places: on the Setup page and in your browser settings.
Setup Page
The Setup page allows the admin to congure:
Controller and Outlet Names
Use the controller name eld to assign a name to the switch.
An example is Rack 4 PDU. The Controller Name will appear on
top of all pages. Assign a separate name to each outlet, such as
DSL Router 1 or Wireless Link to aid identication. Check the
Conrm box to the right of the outlet name if you prefer a pop-
up window conrmation before switching critical circuits.
Power-On Sequence Delay
When a time value is entered in the All ON Sequence Delay
eld, the switch will pause for a period of time before switching
each outlet on in sequence. This delay helps prevent power
surges and blown circuit breakers which can occur when
multiple devices are switched on simultaneously. A delay of 60
seconds is suggested for server applications.
