1. Introduction
WIZ220IO is an embedded remote I/O module which is able to control and monitor I/O port remotely
via Internet. It is possible to monitor and control I/O port by using Windows application program or the
embedded Web server. There are 16 digital I/O ports and 4 analog I/O supported by WIZ220IO.
Additionally, the firmware and embedded webpage can also be updated remotely through the
Ethernet.
WIZ220IO-EVB is the evaluation base board for users to evaluate WIZ220IO module quickly. There
are 8 switches used for digital input test and 8 LEDs for digital output test, and a variable register for
analog input test included in this evaluation board.

1.3. Block Diagram
Figure 1. Block Diagram
WIZ220IO includes not only I/O controlling & monitoring but also I/O value transmission functions.
The users can control or monitor via web browser in remote host PC, and configure the module’s
environment parameters and check the IO status via Configuration Tool program provided by WIZnet.
The interface of WIZ220IO consists of analog interface and digital interface. 12 bits resolution analog
I/O, 3.3V digital output and the maximum 5.5V digital input are supported by WIZ220IO. The digital
I/Os are internally pulled up. The users can use Web browser or Configuration Tool to remotely control
the interfaces.The UART data output can also be displayed in the Web browser.

2. WIZ220IO Base Board
WIZ220IO module can be tested by using base board.
Figure 2. WIZ220IO Base Board Layout
①WIZ220IO Module Connector
It is an interface for WIZ220IO Module.
[Caution] Observe pin position and align when mounting the module on the base board.
Incorrect mounting can damage the WIZ220IO module and base board, and your product
warranty does not cover such damage.

③Switch
8 switches are controlling each Digital Input ports. When you turn switch on, the digital port
signal will be LOW.
Figure 5. DI Switch of the WIZ220IO Base Board
④D-SUB9
This connector is for an UART. The WIZ220IO’s UART port can be used for debug message or
data output through the webpage. It supports RTS/CTS flow control.
⑤Power
The power can be controlled by using power switch after connecting the DC 5V (min 500mA)
adapter.
[Caution] Observe polarity and voltage when connecting the power adapter. Incorrect
input polarity or voltage can damage the WIZ220IO module and base board, and your
product warranty does not cover such damage.
