Bộ Chuyển Đổi HUB 4 Cổng RS-232/485 (UT-2204)

Giới thiệu

UT-2204 is a RS-485 bus split hub designed for RS-485 system used in demanding environments. It supports a data communication rate up to 115.2KBPS and has data buffers and microprocessors. It uses external switching power supply for safety and reliability and is ideal for engineering applications. The built-in discrimination circuit can automatically sense the direction of data flow and switch the enable control circuit to ensure the switch of transmit and receive in RS-485 mode. The communication distance of RS-485 can exceed 1200m for stable performance, so it’s widely used in applications such as video supervision system as a high-performance data interface converter. UT-2204 RS-485 HUB provides star-type RS-485 bus connection. Users can improve the RS-485 bus structure and split bus segments conveniently to improve the communication reliability. This feature significantly improves the reliability of existing RS-485 network and reduces maintenance interval. Reasonable use of UT-2204 RS-485HUB can help to design a unique, highly reliable RS-485 system.
