3.5.1 Default IP Address
The iServer 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
iServer 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 iServer’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 iServer’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 iServer over the network and make any configuration changes
needed. If
192.168.1.200
address is already in use on your network, use an Ethernet
crossover cable between your computer and the iServer to change the IP address or any
other settings within the iServer.
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 port (socket) numbers assigned to the iServer:
1. Port (socket) number 1000 when using HTTPget program (see
Section 4.8
).
2. Port (socket) number 2000 when trying to access your serial device connected to
the serial port of the iServer.
3. Port (socket) number 2002 when trying to access the iServer itself for reading or
changing the settings. This can be done using Windows standard Telnet
application.
Power recycling the iServer can also be done through the iServer’s Web Server (see
Section 4.2
).
Telnet stands for Telecommunications Network, it 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 iServer
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.
