  - TD-1208 is a RS-485 hub (also known as RS-485 bus splitting concentrator, RS-485HUB). Shenzhen Tiandi Huajie Communication Co., Ltd. specializes in the design of satellite wiring for RS-485 bus system in complex electromagnetic environment. The RS485 hub uses bidirectional transparent transmission. The RS485 hub can divide one RS-485 or one RS-232 bus into eight RS-485 buses, or collect eight RS-485 signals into one RS-485 or one RS-232 bus. And each port is independent of light isolation, short circuit and open circuit protection. When the system fails, the built-in controller can cut off the faulty port in time. The RS485 hub ensures that each port works independently and achieves no interference. Each port can connect 32 contacts at the same time, which can extend the 1200 meter RS-485 signal. It is the best choice to change the single structure of RS-485 bus wiring.
