This TCP/IP server board allows manufacturers and system integrators connect their different devices such as home appliances and industrial control systems directly to the Ethernet network, and remotely monitor & control them with standard TCP-IP protocols.
The FMod-TCP DB allows a fast integration in final product during production. A development kit and software libraries are available for fast conception process.
Connections available on boards on the DEVICE side are:
One UART bus
One I2C bus
19 5V digital I/O
5 5V analog inputs
From the COMMUNICATION side, an Ethernet bus allows the use of the following protocols: ICMP (ping), UDP, TCP and HTTP in order to send the data to the dedicated application layer.
