WIZ-IP20-io
wizip20-io is an interface board for the WIZ-IP20 ioPort Serial-to-Ethernet Mag Jack module, providing easy access to UART, power, and control signals for rapid prototyping and evaluation.
WIZnet S2E Solution
-
WIZnet 'Serial to Ethernet' product is a protocol converter that transmits data sent by serial equipment as TCP/IP data and converts the TCP/IP data received through the network back into serial data to the serial equipment.
-
With this product, it is possible to easily add an Ethernet networking function to a device supporting UART/SPI interface, the devices can be controlled via an Ethernet network - Internet.
-
We also provide Customization Services such as change / add functions by customer request.
