Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1-2, a secure two-in-one data interface includes an RJ45 port and a two-in-one data patch cord. One end of the two-in-one data patch cord is an RJ45 crystal plug 2, and the other end is a USB female plug 3 and a DB9 female plug 4. The female USB connector 3 is in signal connection with the RJ45 network port 1 through the RJ45 crystal plug 2, is used as a data transmission port and carries out data transmission with connected equipment. The DB9 female head 4 is in signal connection with the RJ45 network port 1 through the RJ45 crystal head 2 and is used as a debugging port for debugging connected equipment. The RJ45 network port 1 is installed on a device, and as an external data interface, there are 8 pins, and the pin definitions of the pins are shown in table 1 below:
