Enhanced Interference Resistance: This TTL turn to RS485 module includes robust interference resistance and thunderbolt protection measures, specifically designed for 485 bus systems. By grounding the module's "ground" during long-distance transmissions, it effectively prevents interference and protects against thunderbolt strikes. 2. Convenient Development: The 485 to serial UART level mutual conversion features a standard 2.54mm spacing design, making it easy for you to undertake secondary development tasks. It comes with a 120-ohm matching resistor that can be easily connected by shorting R0. This configuration is recommended for long-distance transmissions. 3. Support for Multi-Device Communication: The TTL to RS485 module supports multi-device communication, allowing access to a maximum of 128 devices on the bus. It provides flexibility in setting up complex systems and enables efficient data exchange between multiple devices. 4. Hot-Swappable Design: With its hot-pluggable feature, this hardware automatic flow control module allows for easy installation and removal without affecting other 485 chips or causing signal disruptions. You can conveniently add or replace devices on the bus whenever needed, increasing convenience and reducing downtime. 5. Comprehensive Signal Protection: The 85 to serial UART level reciprocal is equipped with a large copper area, providing effective protection against signal interference. This design ensures stable and reliable data transmission, even in challenging environments where interference may be present.
