1. The hub can prevent bus failures and damage caused by the voltage difference between the power supplies at both ends of the master and slave. 2. This RS485 hub can be optoelectronically isolated, automatically sensed, stable performance, and high-speed transmission. 3. Safety protection, signal port with reverse connection, short circuit alarm indication, and can automatically isolate faulty channels. 4. The internal processor chip can automatically identify and control the data direction without external interference. 5. Using industrial grade, all core chips are imported with original packaging, which is stable and durable.
