Product Description:
This isolated RS485E repeater is a kind of high-performance industrial grade RS485 signal amplifier and extender. It can automatically sense data flow direction and communication baud rate, not requiring any control or handshaking signals, and ensure transparent data transmission. Equipment power supply and communication signal are completely isolated, with surge protection and static protection. It features long distance transmission, high speed, stable and reliable performance. Widely used for attendance machine, IC card charging system, automation control, access control system, parking lot, dining service system, highway toll system.
Signal Common Ground:
1. All devices on the same network segment must have a uniform signal ground to avoid common mode interference.
2. When using centralized power supply, connect DC negative poles of all power (including the communication device power) of the same network segment together directly to form a common signal ground. At this time the signal ground is the DC power ground.
3. When using individual power supply, connect the ground (black wire) pins of all the bus devices on the same network segment together to form a common signal ground.
