More info
This adapter enables direct communication between two devices with serial ports by inverting the transmit and receive signals. It facilitates the interconnection of computers, terminals, or industrial devices that require a crossover cable configuration for data exchange. It centralizes the physical conversion of the cabling in a compact form, resolving communication conflicts in technical maintenance and serial hardware configuration environments.

Communication Series
RS-232 (Recommended Standard 232, also known as EIA/TIA RS-232C) is an interface that designates a standard for the exchange of a series of binary data between a DTE (Data Terminal Equipment) and DCE (Data Communication Equipment , Data Communication Equipment), although there are others in which the RS-232 interface is also used. An equivalent definition published by the ITU is called V.24. The RS-232 is a connectorDB-25 type (25-pin), although it is normal to find the version of 9-pin (DE-9, or popularly also called DB-9), cheaper and even extended to certain types of peripherals (such as serial mouse PC).
