5. TCP/UDP Server
General
The board provides an Ethernet port (RJ45 – connector J7) which allows
access to all parameters (registers) of the module through a TCP or UDP
connection.
Here you will find a small comparison table between these two protocols
(non exhaustive):

CheckSum (Data integrity)
Multiport (data multiplexing)
Flow control
Acknowledge Data
Multipacket order reconstruction
Two ports are available when using the TCP protocol:
Port #80
Port #8010
Only one port is accessible through the UDP protocol:
Port #7010
You will find a detailed description of the different ports in the next pages.
Note: The board allows up to 4 simultaneous TCP connections. That means, for
example, that 4 users can connect to the #80 port to see the web page, or 4
users can be connected to the #8010 port and control the I/Os, or even that
two see the page and two control the I/Os, etc. In UDP protocol, there is no
limitation on the number of users connected.
HTTP port (TCP # 80)
This port is used to access the web page stored on the module.
The user can simply access that port and ask for a particular page, through
the use of a standard Web browser, and typing the IP address of the card:
Ex: type
http://169.254.5.1/index.htm
"index.htm" page will be loaded.
