TWELITE UART

General

Can I communicate immediately after purchase? Is configuration necessary?

The TWELITE UART Series comes pre-flashed with the Serial Communication App (App_Uart), and it is set to Header-Inclusive Transparent Mode.

To switch the communication mode or change settings such as the application ID, you need to use the TWELITE R2/R3 and configure it via Interactive Mode.

Why can’t I use Header-Inclusive Transparent Mode with a brand new device?

It is possible that the Serial Communication App has not been flashed. Please contact us.

Can it be used as a Parent like MONOSTICK?

Yes. By writing the Parent and Repeater App (App_Wings), you can use it as a Parent device and output serial data to an external microcontroller, etc.

Hardware

Is it okay to leave the SET and PRG pins unconnected?

Yes. They can be left unconnected when not in use.

Note that the SET pin is used for overriding the operating mode, and the PRG pin is used when rewriting the firmware.

How can I securely fix it?

For secure fixing, DIP or SMD types are assumed, and we do not recommend any specific fixing method.

Are there recommended pin headers?

There are no specific recommended pin headers, but generally, 2.54mm pitch, 0.64mm square standard pin headers should work in most cases.

What are the specifications of the pin sockets?

They are for 0.64mm square pin headers, with a height of 5mm. Pin headers with an exposed length exceeding 5mm may have some wobble.

Configuration

How do I apply the alternative baud rate setting?

Unlike TWELITE DIP, there is no BPS pin. You need to set the option bit 00010000: Force apply alternative baud rate in Interactive Mode.

How do I reset the settings?

Please follow these steps:

1. Write another TWELITE APP (for example, the Extremely Simple! Standard App) to the device via writing.
2. Access the Interactive Mode of the written app.
3. Execute reset settings (R) and save settings (S).
4. Write back the Serial Communication App (App_Uart).
