FAQ
Question : On what are the key benefits of ES-U-1002-AB & ES-U-1002-MB over their former models, ES-U-1002-A & ES-U-1002-M?
Answer : The ES-U-1002-AB & ES-U-1002-MB models maintain the same functionality, enclosure, and design as their former models, ES-U-1002-A & ES-U-1002-M. However, the key upgrade is the replacement of the FT2232D dual USB-to-Serial UART/FIFO IC with the FT2232H. This enhancement enables High-Speed USB 2.0 (480 Mbps), significantly improving data transfer rates for high-performance applications. The ES-U-1002-AB & ES-U-1002-MB remain compatible with Full-Speed USB hosts like the former models.
Question : What are the common applications for ES-U-1002-AB & ES-U-1002-MB?
Answer : The ES-U-1002-AB & ES-U-1002-MB are USB-to-RS232 adapters designed to add two serial communication ports to a computer. They are widely used in industries requiring legacy RS232 communication, including:
- Industrial Automation & Control – PLC communication, SCADA systems, and CNC machines.
- Embedded Systems & Microcontrollers – PC-to-microcontroller communication for development and prototyping.
