Optical Isolation RS232 to RS485/422 Converter

IT-SC485P is a high performance, more function RS-232/485/422 interface converter. The product configure out connect power, optic-electrical isolation more than 2.5KV. Have small volume, far transmission distance, high rate, steadily performance and so on. It is abroad used in industry control system, It is an interface convert product that have good between performance to price. Adopt it self adapt interface technique, no use for setup switch.
