The Experiment Control and Monitor (EC & M) software was developed at NASA Lewis Research Center to support the Advanced Communications Technology Satellite (ACTS) High Burst Rate Link Evaluation Terminal (HBR-LET). The HBR-LET is an experimenter's terminal to communicate with the ACTS for various investigations by government agencies, universities, and industry. The EC & M software is one segment of the Control and Performance Monitoring (C & PM) software system of the HBR-LET. The EC & M software allows users to initialize, control, and monitor the instrumentation within the HBR-LET using a predefined sequence of commands. Besides instrument control, the C & PM software system is also responsible for computer communication between the HBR-LET and the ACTS NASA Ground Station and for uplink power control of the HBR-LET to demonstrate power augmentation during rain fade events. The EC & M Software User's Guide, Version 1.0 (NASA-CR-189160) outlines the commands required to install and operate the EC & M software. Input and output file descriptions, operator commands, and error recovery procedures are discussed in the document. The EC & M Software Maintenance Manual, Version 1.0 (NASA-CR-189161) is a programmer's guide that describes current implementation of the EC & M software from a technical perspective. An overview of the EC & M software, computer algorithms, format representation, and computer hardware configuration are included in the manual.
