3.5.1 Default IP Address
The iSE is shipped with a default IP address set to 192.168.1.200 and Subnet Mask of
255.255.255.0. If you are going to use a Web browser or Telnet program to access the
iSE using its default IP address, make sure that the PC from which you’re establishing
the connection has an IP address that is in the same range as the iSE’s IP address
(192.168.1.x, where x can be any number from 1 to 254.
Your PC’s IP address cannot
be the same as the iSE’s IP address).
You also need to make sure that your PC’s Subnet Mask is 255.255.255.0. This is a
good way to access the iSE over the network and make any configuration changes
needed. If 192.168.1.200 is already in use on your network, use an Ethernet crossover
cable between your computer and the iSE to change the IP address or any other settings
within the iSE.
3.6 Port Number
All TCP connections are defined by the IP address and a port number. A port number is
an internal address that provides an interface between an application running on your
computer and the network through the TCP/IP protocol.
There are three default TCP socket port numbers assigned to the iSE:
1. Port (socket) number 1000 when using HTTPget program.
2. Port (socket) number 2000 when trying to access the sensor (probe) connected to
the port of the iSE to receive data.
3. Port (socket) number 2002 when trying to access the iSE itself for Power
Recycling the iSE remotely. This can be done using Windows standard Telnet
application.
Power recycling the iSE can also be done through the iSE’s Web Server (see Section
4.2).
Telnet stands for Telecommunications Network, is a protocol that provides a way for
users (or clients) to connect to computers (or servers) on a network, whether in the next
building or across the world.
Example: C:\>Telnet 192.168.1.200 2002
You will then get the following screen.
Figure 3.3 Telnet Login into the iSE
You can open a Telnet session using other terminal emulation programs like Tera Term
Pro (downloadable from the internet), which is a free software for MS-Windows. It
supports VT100 emulation, Telnet connection and serial com port connections.
