Data Flow and Automatic Control

The UT-890A features an internal zero-delay automatic receiving and transmitting function. This means the converter automatically detects the direction of data flow, eliminating the need for manual control signals. This ensures seamless communication between your computer and the connected RS-485/422 device.

LED సూచికలు

The converter is equipped with LED indicators to provide visual feedback on its operational status:

• PWR (పవర్): Indicates that the device is powered on and receiving power from the USB port.
• TXD (డేటాను ప్రసారం చేయండి): Flashes when data is being transmitted from the computer through the converter to the serial device.
• RXD (డేటా స్వీకరించండి): Flashes when data is being received by the converter from the serial device and sent to the computer.

This video provides a brief introduction to the UOTEK UT-890A converter, demonstrating its features and typical usage scenarios, including the LED indicators for power and data transmission.
