Specification
Interface Standard --Compliant with RS485 Standard
Physical Interface --RS485 Screw Terminal
Baudrate--300~460800bps (self-adaptive)
Supported Nodes--Each RS485 port supports up to 32 nodes
Communication Distance --1200m (9600bps), the higher rate the shorter distance
Operating Method --RS485 two-wire (A, B), half-duplex transparent transmission
Power Supply --DC 9~24V
Operating Temperature ---45 ~ +85℃
Environment Humidity -- Transmission Medium --Normal parallel cables/twisted-pair cables

Supports RS485 network relay, extension and isolation functions
1. 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.
2. 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.
3. 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.
