- General Introduction
RS232-RS485 Converter is the RS-232 RS-485 serial signal inter-conversion, differential half-duplex, network-based active converter between RS-232 and RS-485. This product has features of a strong drive capability, simple and practical interface ,anti-lightning, anti-surge, anti-static, stable design and performance, beautiful appearance and so on. It comes with power indicator and data traffic lights to direct communication fault conditions. It’s a cost-effective and good performance data interface conversion item.
- Important features
Jumper-free DIP switch setting, adaptive connections, simple wire conecting,direct and clear communication situation feedback,, easy installation , maintenance and troubleshooting
Three level international standards for lightning protection design, lightning hit 50 consecutive 5000V is not bad, and it’s safe and secure with relative level index of anti- static and anti-surge indicators,.
Increase the transmission distance between the controller and compute. If 232 communication generally support transmission distance within 20m, it will support over 1000m with use of 485P convertor.
485+ and 485- the two must be mutually twisted-pair cable, you can use one pair of the four pairs cable.
485 must be hand in hand, bus-type structure that is resolutely forbidden star connection and branching connections.
