1、Soft wire, does not affect communication in winter, convenient and practical. 2、The cable is protected by optical coupling isolation, and the protection circuit can also reduce external signal interference and assure communication quality. Support MPI, PPI, DP port programming. The baud rate is adaptive. 3、Nickel‑plated connectors, low resistance, reduce plug wear. 4、The isolation chip mainly plays the role of protection and stable communication. The cable with isolation is more stable than the one without isolation, data transmission is faster, and the ability to resist external interference is strong. It is generally used in environments with many interferences, such as frequency converters, modules and other industrial sites with large interference. 5、Free driver (no need to install driver in V5.5), no need to generate serial port, select USB direct 6、Choose PTC self‑recovery fuse, which can protect well in the case of overvoltage, overcurrent and short circuit.
