-
Remote IP Address / Remote Port Number: It is valid on "TCP Client" and "UDP" modes.
Input the host IP address and port number.
-
Keep TCP connection: If you check this option, the WIZ220IO module maintains the
connection as sending keep-alive packet. If you uncheck this option, the module closes the
connection after sending data.
-
Time period to sending: It is possible to set the sending period. To disable notification
option, input '0' to this parameter.
3.3. Serial Tab
Serial tab is for the UART configuration. The UART is used to display debug message and to output
the UART data through the webpage.
-
Speed: It supports baud rate from 1200bps to 230400bps.
-
Data Bit: It supports 7bit or 8bit of data bit.
-
Parity: It supports odd, even and none option of parity.
-
Stop Bit: It supports only 1bit.
-
Flow: It supports flow control – none, RTS/CTS.
3.4. Input / Output Tab
Input/Output tab is for the I/O control and monitoring. When you click the "Update I/O Status" button, it
will be displayed I/O parameters at that time.
In the Digital parameters, a green indicator means port is asserted 'HIGH' and a gray indicator means
'LOW'. Each port can be set 'HIGH' as checking checkbox in 'Digital Output Control' and click the
'Update I/O Status' button.
The Analog I/O has range from 0 to 4095 and it has voltage type. In the Analog input status, '4095'
means maximum input value that is same to '5V_Input' (Vcc) value. However, analog output
maximum value '4095' generates 4V. In other word, the analog output maximum value is 4V.
[Warning] At the digital input, if you set the switch on the base board, module recognizes it as
"low". At the digital output, when the module is "low", LED on the base board becomes on.
