Supports 300～460800bps Wide Baud Rate Communication Range (Self-Adaptive)
Generally, the RS485 requires a hand-in-hand connection, if a star connection (master station as the centre) is required, this RS485 hub can effectively isolate the connection interference between multiple RS485.
Function
Extension-
When the master RS485 device needs to connect 8x RS485 slaves in a star connection, connect the master to the RS485-HUB-8P master port and the slaves to the RS485-HUB-8P slave port. It can prevent interference between RS485 and isolate effectively.
Isolation-
By connecting one end of the RS485 to the RS485 master port and the other end to any RS485 slave port, the RS485 cable is effectively isolated and protected from lightning strikes and interference. The other end of RS485 is effectively protected from damage by high voltage and strong current.
Relay-
When the RS485 cable exceeds a long distance such as 1200 meters, the signal will be attenuated and interference will increase. By using RS485-HUB-8P, the communication distance can be extended.
