Additional Requirements

How to use

The terminal is printed with "a, c, b" on the board. When the relay is turned on, a-c is connected and c-b is disconnected. When the relay is turned off, a-c is disconnected and c-b is connected. When the power is turned on, it always starts from the OFF state (c-b is connected).

IWT303 is controlled by the TD-USB command. TD-USB is a command-line program that works on Windows/Linux.

Example) td-usb iwt303 set 3

set is a fixed string that updates the status of the relay. The setting value "3" becomes binary 011, updating CN1 and CN2 to ON and CN3 to OFF. If 2 is specified as the setting value, it becomes binary 010, so only CN2 is ON, and CN1 and CN3 are OFF.

If you want to control it from your own developed program, please use TD-USB as an external program. For details, please refer to the README of TD-USB.

Also, on Windows, you can control the relay from the screen using the demo application TD-AppKit.
