Using the Multi DIO application, you can control each pushbutton switch directly or via the IzoT network using the demo Web pages, as shown in the Dashboard Web page.
The following video describes how to create a network with the Multi DIO application:
...
The Multi DIO example application works with the following hardware:
- Raspberry Pi
- PiFace Digital -- the PiFace Digital is a digital I/O board with the following inputs and outputs:
- 8 digital inputs
- 8 digital outputs
- 8 LEDs that indicate the state of the 8 digital outputs
- 2 relays
- 4 pushbutton switches connector to the first four digital inputs.

| Flag / Option | Description |
|---|---|
| -C | Enables debugging with the PyCharm IDE. |
| -D | Runs the Touch Keypad example applicaiton in debug mode. The log level is increased for both the console log and the application log. |
| -d DEVICE | Sets the device URI, e.g., uc://10.0.1.12:1628. If If not specified the default URI is used. |
| -h | Displays the available flags and options. |
| -I | Disables ISI. Without ISI, the application requires installation by a network management tool such as the IzoT Commissioning Tool. |
| -i | Runs the Touch Keypad without any attached I/O hardware. This is useful for running the Touch Keypad on platforms that do not have the Touch Keypad I/O hardware. |
| -l LOG | Sets the path and filename for log files. If not specified, the default path is the Touch Keypad example directory, and the filename is 3-chan-dio. |
| -m | Runs the Touch Keypad in demo mode. In demo mode, periodic ISI messaging is increased to speed up device and connection discovery. The result is that more bandwidth is consumed for ISI messaging provide faster discovery at the expense of less bandwidth for application data. |
| -n NVD | Specifies the path for the non-volatile data directory. If not specified the default directory is 3-chan-dio-nvd in the Touch Keypad example directory. |
| -p PROGRAM_ID | Specifies a program ID for this running instance of the application. PROGRAM_ID is a 16-digit hex value described in the Defining the Program ID. If not specified the default program ID for the Environment Sensor example application is 9F:FF:FF:05:00:51:00:31. Specify a different program ID if you have modified the IzoT interface for the example application and you need to load a different device class file for the modified application. |
| -r RESET_TYPE | Clears persistent data. Set RESET_TYPE to 0 to clear all persistent data; set RESET_TYPE to 1 to clear all persistent data except for the device unique ID. RESET_TYPE 1 is useful to prevent a change in unique ID which will result in a new discovery of the device by the IzoT Server. |
| -v | Runs the Touch Keypad example application in verbose mode. The log level is increased to the maximum level for both the console log and the application log. |
