The newly received inventory is all packed in yellow cartons. The line is 6m long and the article weighs 446g. It is also returned from the inventory. This line only supports the maximum 115.2 baud rate, not 187.5 baud rate. Pay attention when purchasing. PC / PPI + programming cable is a communication cable from RS232 to PPI interface (RS485), which is suitable for Siemens S7-200 series PLC. It supports PPI Protocol and free port communication protocol, photoelectric isolation and built-in photoelectric isolator, which can provide isolation voltage up to 2500vrms. It is equipped with fast transient voltage suppression protector, which is designed to protect RS-485 interface, Adopt today’s advanced TVs Transient voltage suppressor. Normally, the TVS tube is in a high resistance state. When both ends of the TVS tube are subjected to an instantaneous high-energy impact, it can reduce the impedance at both ends at a very high speed and absorb a large current, so as to clamp the voltage at both ends at a predetermined value and protect the subsequent circuit components from damage due to the transient high-voltage impact The protector can effectively suppress lightning and ESD, provide 600W lightning surge protection power for each line, as well as surge voltage and transient overvoltage generated on the line for various reasons, and the very small inter pole capacitance ensures the high-speed transmission of RS-485 interface. The RS-232 interface end is connected with the compatible RS-232C standard interface through a DB9 female connector, and the RS-485 end is connected through the DB9 male connector. The converter is equipped with zero delay automatic transceiver conversion. The unique I / O circuit automatically controls the direction of data flow without any handshake signals (such as RTS, DTR, etc.), plug and play Ensure that it is suitable for all existing communication software and interface hardware, and there is no need to make any software modification to the previous working mode based on RS-232.

The goods are all packed in yellow cartons as shown in the figure below, with a box weight of 446g.
