Research and Implementation of LXI Auto Discovery Mechanism
Xi Jun Zhang, Hao Liu · Applied Mechanics and Materials · 2015
Instrument discovery as defined by the LXI standard implements the VXI-11 instrument discovery protocol. This mechanism allows the user to quickly discover instruments on a local subnet. The paper describes how to implement the auto-discovery RPC server compatible with LXI standard. For better understanding auto discovery process, it starts by introducing the VXI-11 protocol stack and follows with the deep analysis of auto discovery process. Finally, it discusses how to implement the RPC server. The RPC server supports both windows XP and windows CE operating system. The auto-discovery RPC server passes the tests on the Elgar LXI Browser, Agilent IO Library Suite and NI Measurement and Automation Explorer.
