Laboratory balance with PS/2 interface

PS/2

— specialized connector for connecting scales to a PC; has a characteristic round shape. In terms of functionality, such a connection is similar to USB (see the relevant paragraph); The peculiarity of PS/2 is that such ports are found mainly in full-sized PCs (and even then not necessarily) and are practically not used in laptops. As a result, few scales with such a connector are manufacturing nowadays.
