Function.It is widely used in remote distance power transmission and city secondary substation（35/110kV).
SVG needs to access the communication processor on backstage by RS485 interfaces at the scene, is carried out with the communication processor on backstage
RS485 is communicated, and the data of SVG are finally transmitted to background monitoring system by communication processor.Debugging initial stage can lead due to various reasons
It causes communication connection abnormal, at this moment needs on-site service personnel's carrying notebook computer, the USB-485 converters to scene of SVG, adjust
Try the RS485 communication interfaces of SVG.On-site service personnel is not equipped with laptop individually generally, if only because debugging SVG
RS485 interfaces and be equipped with laptop, it is desirable that on-site service personnel carries, and not only increases the negative of attendant
Load, also increases the cost of serving of company.
