1 Description
1.1 Purpose
The purpose of this document is to define the interface between Monitor and Control System Data
Recorder (MCS-DR) and other Long Wavelength Array (LWA) station subsystems. The MCS-DR
subsystem records output of the Digital Processing (DP) subsystem and is controlled by the Moni-
tor and Control System (MCS). Whereas station architecture and subsystem ICDs may refer to the
MCS-DR as a whole, this ICD applies to a single MCS-DR PC.
1.2 Scope
This ICD shall describe the MCS-DR’s physical and electrical connections, software interfacing and
control methods.
