Product Description:
This product is a high-performance and multi-functional RS232-485 interface converter. This product is a passive converter with small size, long transmission distance, high speed, and stable performance. It is widely used in monitoring systems, attendance systems, and IC card charging systems. It is a cost-effective data conversion product. Supports 32/128 nodes.
The main function:
- Semi-bidirectional conversion of RS232 and 485 signals, one RS485 signal output
- Efficient power stealing, no external power supply required;
- Hot plugging, only RX and TX, serial port protection.
Technical Parameters:
- Speed 0-115200BPS
- RS485 transmission distance is 1200 meters (at 100kBPS)
- Working temperature -10 to 70 degrees
- RS485 port has the anti-static, anti-lightning design
- 128 nodes
Instructions:
- The DB9 interface is an RS232 port, connected to the COM port of the system control port
- (A), (B) are RS485 signal output ports, and connected to control equipment, such as a decoder. For RS485 communication, it is a half-duplex communication method
- The 485 interfaces of the most remote RS485 device of the output circuit is connected with a 120Ω resistor in parallel, and one circuit is not more than a 120Ω resistor
- The RS485 communication specification requires a shielded twisted pair connection. If parallel cables are used, the communication distance will be greatly reduced.
