| Abstract: | In this paper,a cross-backup method for LVDS interface on high-reliability data transmission system is described in detail.The differences between the cross-backup of LVDS and the one of TTL end are compared.The method of cross-backup way in TTL level port is discussed with focus on a few typical methods,which can isolate the failure between the host and the backup instruments.Subsequently,a method named resistance-linking is adopted in the data transmission system,which is featured by simplicity and reliability. |
