2. Configuration of the Power Switch
To use the Power Switch on your network you must first configure its network parameters. Ask
your network administrator for the parameters to use.
There are three different methods to configure the Power Switch:
Method 1:
Through a network using the Power Switch Finder Program (on the delivered CD).
It is the simplest and fastest configuration method if you use Windows as operating system. We
suggest that you use this program at least during the first configuration: it allows you to
configure your Power Switch through your local network even if its network parameters (IP
Address, Subnet mask and Port) are not compatible with those of your PC or your local
network.
If you decide to use this method you can directly go to §3 "Configuration using the Power Switch
Finder program".
Method 2:
Through a network using a Web browser (Internet Explorer > 6.0 and Netscape > 6.1).
This method can only be used if the network parameters of the Power Switch (IP Address,
Subnet mask…) have already been configured using either the Power Switch Finder program
(Method 1) or a Terminal program (Method 3).
For the first configuration you can also change the Network parameters of your PC according to
the default settings of the Power Switch.
Default Network setting of the Power Switch:
IP Address: 192.168.100.100
Mask: 255.255.255.0
Port: 80
If you decide to use this method you can directly go to §4 "Configuration using a Web browser".
Method 3:
Through a RS232 serial connection using a Terminal connection (see §7 "serial port pin
configuration" for the configuration of the serial interface connector).
If you use a PC, use the serial cable supplied with the product and a Terminal program such as
HyperTerminal from Microsoft.
If you decide to use this method you can directly go to §5 "Configuration using a Terminal
connection".

3. Configuration using the Power Switch Finder program
Remarks:
∇ The Power Switch and the PC used to configure it have to be connected on the same
segment of the network. The protocol of this program can not be routed so it can not be used
to configure the Power Switch through a WAN or the Internet.
∇ This program does not work if the administrator has deactivated it in the configuration of the
Power Switch (for security reasons for example).
1. Start the program PS-Finder.exe on the CD-ROM.
The Power Switch Finder window appears.
2. In the tool bar click on the first left button or choose the File/Scan Menu.
The program browses the segment on which is connected your PC and displays the name,
the type, the IP and MAC Address of the connected Power Switch.
3. In the tool bar click on the second left button or choose the File/Configure Menu.
The properties dialog box appears and you can now configure all parameters. To configure
all other parameters click on the Options button on the bottom of the dialog box.

6. Security parameters configuration
Explanations about the masks settings:
∇ Each mask can be an IP address or a range of IP addresses.
∇
Each mask allows you to authorise or deny access to the Web server of the Power Switch to
specific addresses or to specific ranges of addresses.
∇
Each mask can be activated or deactivated (without function in this case).
∇
Each IP address consists of a series of four eight-bit numbers. The number 255 is used as a
wildcard, so it replaces all others.
∇
Masks are listed in order of descending priority; so Mask 1 has the highest priority.
∇
Masks have a cumulative effect; high priority masks supersede the effect of lower priority
masks.
Example 1:
⇒ Deny the access to all IP addresses except 192.168.001.015

7. Ping and Port Scanning
Power Switch has two methods to check whether an IP equipment (PC, server, router,
Webcam...) is still alive.
Ping
The first method uses the well-known Ping command whereby a request is sent to a specific IP
address. The Ping command, which is an echo request, enables you to determine through an
ICMP protocol (Internet Control Message Protocol) if an IP device is available on the network. If
the system reacts to this request, Power Switch knows that the TCP/IP connection is
established. If the system does not react to one or several requests, Power Switch can
automatically switch off and after a specified delay switch again on the IP equipment (Reboot).
Port Scanning
The second method uses the Port Scan command to test a specific TCP/IP port. In other words,
this command allows you to find out if a specific protocol is available on a server (for example
HTTP, FTP, Telnet, SMTP, POP...). Power Switch simply tries a connection to a specific server
port. If the connection is possible, Power Switch knows that a server program is running there. If
the connection is not possible, Power Switch can automatically switch off and after a specified
delay switch again on the IP equipment (Reboot).
Remarks:
− The Ping and Scan function can be used separately or together.
− The network route between Power Switch and the IP device to supervise should be as direct
as possible, so do not use unnecessary routers and complex wiring between them. A
problem on a router or the wiring could reboot the IP device to supervise.
− Execute several Pings and/or Scans before running the Reboot function. It could be possible that the IP device
to supervise doesn't respond although the IP device is still working.
− Choose a realistic supervision cycle. One second is possible, however it’s not necessary to overload the
network with Pings and Scans requests.
Recommended values:
Interval between Requests 10 sec or more
Number of unsuccessful Requests
before Reboot
3 or more
Delay before Reboot 10 sec or more
Delay before first Request after Reboot 120 sec or more

9. Command the state of the socket through a Web browser
1. Start your Web browser
Type the IP address of your Power Switch.
The browser displays the authentication dialog box.
2. Enter a user name and its corresponding password.
− If you enter the administrator name (default value = admin) and the administrator password
(default value = admin) and click OK, you will be able to control the socket status and also
to configure all the parameters of the Power Switch.
− If you enter the user name (default value = user1) and the user password (default value =
user1) and click OK, you will be able to control the socket status only.
The button Power allows you to switch the socket ON and OFF.
The button Restart allows you to switch the socket OFF. It will be automatically switched on
after the delay fixed by the administrator during the configuration (default value is 5 sec).
Under the command button is displayed the state of the IP supervision.
− If the supervision function is deactivated (can be done by the administrator only) the
message «Supervision deactivated» is displayed.
− If the supervision function is activated (can be done by the administrator only) the message
«Supervision activated» is displayed.
Remark: if you switch the socket OFF, the supervision function is temporarily deactivated
and the message "Supervision temporarily deactivated" is displayed.

SW161A Power Switch Maverick 1-Port User Guide
10. Command the state of the socket through a serial connection
The socket of the Power Switch-1 can also be controlled using a simple ASCII protocol over a
RS232 serial connection.
To control the power socket:
1. Use the supplied RS232 serial cable to connect the Power Switch-1 to an available serial port
of your PC.
2. Run a terminal program such as Windows HyperTerminal.
3. Configure the appropriate serial port of your Terminal program with the following settings:
9.600 bauds, 8 bits, no parity, 1 stop bit, no flow control.
If you use the MicroTerminal program on the CD (folder miscellaneous) you have only to
choose the used serial port, this program is already configured at 9.600 bauds, 8 bits, no
parity, 1 stop bit, no flow control.
4. On your computer, press <ENTER> until the prompt «>» appears on your screen.
(the Power Switch is now in command mode and is waiting for commands to switch the
power socket).
Remark: the power outlet of the Power Switch can only be controlled if the Power Switch is in
Command mode and NOT in Configuration mode. If you are in Configuration mode, type the
/RS command to leave this mode. By default, the Power Switch is in Command mode after a
power up.
Use the following commands:
p=1 and press <ENTER> to switch the socket ON
p=0 <ENTER> to switch the socket OFF
p=r <ENTER> to restart the socket
p=t <ENTER> to toggle the socket
The Power Switch accepts lower case and upper case commands.
The version of the firmware can be displayed by typing "?" followed by <ENTER>.
