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 a TCP/IP interface between an application software on
a computer and a device on the network or between two devices on the network.
There are two default TCP port (socket) numbers assigned to the iServer:
1) Port 2000: Once a TCP connection is made to the iServer using port 2000 or any
port number that is configured on the iServer for Local Port (see Network menu,
Section 4.4.2), the iServer can then be polled for variables like temperature,
humidity, etc. using commands. For the list of commands see Section 4.9.1.
2) Port 2002: This port is the iServer's network console port for reading or changing
the settings within the iServer. For the list of settings refer to Section 4.8.1. For both
of the above cases, for example, a Telnet application can be used.
PART 4
oPeRATIoNS
Depending on user's preference and network setup, the iServer can be configured in
several ways:
Using the latest versions of Web browsers like Internet Explorer, Firefox, Opera, or
Safari (iPhone) the iServer's Web server can be accessed, see Section 4.2.
It can also be configured using a TCP connection to port 2002 using a command line
interface, see Section 4.8.1.
The iCONNECT Configuration Software can also be used to find and configure the
iServer over the Ethernet, see Section 4.1.2.
Before you configure the iServer, you will need to assign an IP address to the
unit. Refer to Section 4.1.1, 4.1.2 or 4.1.3.

4.1 IP Address Assignment

4.1.1 DHCP (Method 1)

The DHCP server will assign an IP address, see Section 3.3.

4.1.2 ARP HTTPget Commands (Method 2)

You can download the HTTPget program from our web site to use it for this section.
1. From the Command line (DOS prompt) where you keep the HTTPget.exe file, type the
following:
arp -s 128.100.101.76 00-03-34-00-b8-70
128.100.101.76, for example, is the IP address that you want to assign to your iServer
and 00-03-34-00-b8-70 is the MAC address of your iServer labeled on the bottom of the
unit.
2. From the same prompt, type the following HTTPget command:
httpget -r -S "00000000" 128.100.101.76:1
00000000 is the default ADMINISTRATOR password in your iServer unit and
128.100.101.76:1 is the IP address that your iServer will accept on TCP port 1. At this
point, you have successfully assigned 128.100.101.76 IP address to your iServer.
