Additional Requirements
A 12V power supply capable of providing 1A is needed for the relays. You can connect the power cable directly to the terminal block or use an AC adapter. If using an AC adapter, consider the suitable AC adapter (IWAC12-1.0) listed in the related products.
How to Use the Control Program
The IWT313 is controlled using the TD-USB command. TD-USB is a command-line program that works on both Windows and Linux.
Example
> td-usb set 255
This command turns ON all relay channels on the connected IWT313-USB.
The first argument set
is a fixed command string to configure the relay state.
The second argument 255
represents 11111111
in binary, meaning all 8 channels are ON. If you specify 128
, it translates to 10000000
in binary, so only channel 8 is ON, while the other channels remain OFF.
To control the module from a custom program, call TD-USB as an external program. For more details, refer to the TD-USB README.
Additionally, on Windows, the demo application TD-AppKit allows relay control through a graphical interface.
Notes
If an error indicating that vcruntime140.dll
is missing appears at startup, please install the necessary library here.
The old control program "iwt313ctl" is still available for use and download but will not be maintained in the future. For new development, use the TD-USB commands.
