| Abstract: |
| In order to guarantee the capability of the data communication of software based on RS422 interface, a testing device is introduced. The device consists of a FPGA card (slave computer) and computer (master). The detection for the data communication capability of aerospace software with RS422 interface is realized by adjusting the baud rate, data frame format and time interval in data packets. |
