Product Description:
This insulated RS485E repeater is a kind of high performance industrial RS485 signal amplifier and extender. Automatically detects data flow direction and communication baud rates without the need for control or handshake signals, ensuring transparent data transmission. The power and communication signals of the device are fully insulated, surge protection and static protection. Features long distance transmission, high speed, stable and reliable performance. Widely used in attendance machines, IC card charging systems, automatic control, access control systems, parking lots, dining service systems, highway toll systems
Signal Common Ground:
1. To avoid common mode interference, all devices on the same segment need uniform signal gland.
2. If you use a concentrated power supply, you can directly connect the DC negative pole to all power sources of the same segment (including the power of the communication device) to form a common signal gland. At this time, the signal ground is DC power ground.
3. If you use a separate power supply, connect the ground (black wire) pins of all bus devices on the same segment to form a common signal ground.
