Problems solved by technology

[0002] On commonly used industrial instruments and equipment, network interfaces and serial signal interfaces (such as: TTL interface, RS-232 interface, RS-485 interface, empty contact interface, single-mode optical fiber interface, multi-mode optical fiber interface, etc.) are commonly used interfaces. In the prior art, the network interface, TTL interface, RS-232 interface, RS-485 interface, empty contact interface, single-mode optical fiber interface, multi-mode optical fiber interface, etc. are usually designed side by side. On instruments and equipment, the total number of interfaces is even more astonishingly large
