WebSwitch™ Users Manual
WebSwitch™ is installed on a separate private network. For example, if the user doesn't control the
network connections where WebSwitch™ is installed, “Remote Services” would initiate a TCP
connection over the Internet with the control computer. Since WebSwitch™ initiates the connection, the
control computer doesn't have to know the IP address of WebSwitch™. This means that WebSwitch™
can be installed using DHCP. In addition, no special router configuration is required. This makes the
network installation of WebSwitch™ very simple, and since no incoming ports need to be opened in the
router, security is not compromised. See the
Advanced Network
Tab for more information.
WebSwitch™ can be configured to establish a connection when triggered by an event, such as an Outlet
state changing. This is done by setting the Remote Service/SNMP checkbox in the setup tabs.
When an event occurs and a connection is open, the state.xml file is sent.
If a connection is not open and Remote Services is enabled, a connection will be established by sending
the connection string. Once the connection is established state.xml will be sent.
Connection String
With Remote Services enabled, a connection attempt will be made periodically according to the
Connection Interval setting in the
Advanced Network
setup tab. The Connection String is a user-
defined character string configured in the
Advanced Network
tab.
The connection string is also sent at the same interval once the connection is open. The external server
is responsible for closing the connection when it is done.
