5. TCP/UDP Server
General
The board provides an Ethernet port (RJ45 — connector
J7) which allows accessing all the 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):
Features
CheckSum (Data integrity)
Multiport (data multiplexing)
Flow control
Acknowledge Data
Multipacket order reconstruction
Two ports are available using the TCP protocol:
Port #80
Port #8010
Only one port is accessible through the UDP protocol:
Port #8010
You will find a detailed description on 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.
for HTTP communication.
