Application and access possibilities
SIP
The core function of the SIP ring switch is to switch outputs by dialing extension
numbers in an IP PBX. The communication with the telephone system based on SIP
(Session Initiation Protocol).
Browser access
Using password protected access, you can also switch the outputs with the required
access rights.
Email sending
The SIP Ring Switch offers the option of sending email messages depending on
output states or at xed intervals. The SIP Ring Switch also supports authentication
procedures prescribed by public providers.
Web-API - HTTP requests / AJAX
The status of the outputs can be queried using HTTP requests. In addition the
outputs can be directly controlled using HTTP requests.

13
Product introduction
Individual applications
The SIP Ring Switch offers TCP socket access from your own applications.
The SIP Ring Switch supports addressing using command strings. With the support
of HTTP requests your own web applications (e.g. with PHP or JavaScript) can also
access the SIP Ring Switch.
Actions
Which output is to be switched to which state when a certain extension is called is
determined by creating corresponding actions.
In addition, actions can be created that are triggered by changes to the outputs or at
certain times, e.g. the sending of an e-mail message. Further actions are writing to a
le via FTP, sending data via TCP or an HTTP request, up to switching the outputs of
a SIP ring switch accessible via the network.

With a typical industrial power supply of 24V, the SIP Ring Switch draws approxima-
tely 100mA of current.
1NOTE
IO channels that are congured as outputs are also supplied via VDD. The loads to
be switched must also be taken into account in the current consumption.

Installation and wiring
Output wiring
IO channels that are congured as outputs operate as current drivers and can be
loaded with max. 500mA each. The positive voltage applied to VDD .is switched to
the positive terminal of the IO channel, whereby the negative terminal is used as re-
ference ground.

Initial start-up
6. Initial start-up
After the SIP Ring Switch has been properly installed and wired, the power supply
can be switched on. All three status LEDs should light up briey. After approx. 5
seconds only the Power LED should remain on. The Status LED may ash.
If the network connection is working, the green LED in the network socket signals an
active link. The orange LED indicates the network speed:
On = 100MBit/s
Off = 10MBit/s
Assigning the IP address
At delivery, the SIP Ring Switch is set to IP address 0.0.0.0.0 and DHCP is activated.
Networks with DHCP
If a DHCP server is active in the network to which the SIP Ring Switch is connected,
an IP address should be automatically assigned to the SIP Ring Switch. To be able
to specically access the SIP Ring Switch, you should congure a reservation in
the DHCP server so that the SIP Ring Switch is always accessible under the same
address. The required Ethernet address can be found on the white sticker on the
device.
xxx
(If in doubt ask your network administrator)
Networks without DHCP
Install the WuTility program on a Windows PC (download from http://www.WuT.de).
If you do not have a Windows PC, read the subchapter Alternatives for IP address
assignment in the appendix.
When WuTility is started, the local subnet is scanned and all detected W&T network
components are listed. Select your SIP Ring Switch and click the IP address icon.

18
Initial start-up
WuTility suggests the network parameters (subnet mask, gateway, DNS server) that
also apply to the PC. If you want the SIP Ring Switch to work in the same subnet as
the PC, you only need to adjust the IP address.
If you select Address range > any network, you can also enter parameters which are
different from your local network, for example to pre-congure the SIP Ring Switch
for a different network.
Changing the set IP parameters
To change the IP address, subnet mask, gateway or DNS server later, you can either
use Wutility again or adjust the parameters using the browser under Basic settings »
Network.

19
Basic settings
7. Basic settings
The further conguration of the SIP Ring Switch is done using a web browser. Enter
the IP address of the Web IO in the browser command line. In the navigation tree,
click Login and choose Administrator as user. By default, no password is assigned
and a click on the login button is sufcient to congure the SIP Ring Switch with
administrator rights.
Conguring the Outputs
In Basic settings » Outputs you can give individual names to the outputs. These
names replace the factory default names Output n in the visualization and any
message texts.
Expanded output settings
For special applications some output properties can be modied:
Inverted output characteristics
Normally the outputs are switched off in OFF state (i.e. without signal) and switched
on in ON state. By activating the inversion, the output congured in this way acts
exactly reversed.
Pulse mode
By activating the Pulse Mode, the output automatically returns to the OFF state after
the selected pulse duration when it is switched to the ON state. When switched
on again during the pulse, the pulse duration starts counting again. Reset Allowed
species that the output may also be switched to the OFF state during a current
pulse.
Pulse mode (flashing signal)
For some signaling applications it is helpful if the signal is not switched permanent-
ly to ON or OFF state, but changes continuously between ON and OFF.
If a negative value is entered as pulse duration, the output falls back to OFF after
the specied time and automatically switches back to ON after four times the pulse
duration. If a pulse duration of e.g. -1000 is entered, the output remains switched on
for one second and then switches off for four seconds.

20
Basic settings
This is repeated as long as the output is active.
Date / Time
In the Date / Time section you can dene whether a periodical adjustment with a
time server should take place. In addition, date and time can also be set manually.
The conguration of a time zone and the daylight saving time can also be done here.
Language / Info
In addition to the language selection German or English, further display elements,
including the logo, can be modied here.
Password
The passwords for administrator and user can be set in this section.
Please note that the same password should not be used for Administrators and
Operators.
If the administrator password is no longer known, physical access to the Web IO is
required to reset the passwords. See the chapter Emergency Access in the appendix
of this manual.
