An Auxiliary Interface Instrumentation Module for the AMRL Low Speed Wind Tunnel Data Acquisition System

Abstract

An IBM PC based electronic module is described which extends the capability of the data acquisition system of the Low Speed Wind Tunnel (LSWT) at the Aeronautical and Maritime Research Laboratory (AMRL). Occasions arise when wind tunnel measurements require external data input or specific data extraction by external or temporarily acquired equipment. Access to the data is provided by the Auxiliary Data Module (ADM). The ADM is one of the VME modules in the LSWT instrumentation console. The functions of two types of plug-in commercial board are used to provide a suite of digital input and output functions using a total of three boards. Two input, two output and two tachometer channels are provided by two identical I/O boards in addition to the two standard PC RS-232C serial communication ports. The second plug-in board type provides eight analog input channels and two analog output channels with 12 bit resolution.
