This document de
44、fines the management information for a Data Collection and Monitoring (DCM) unit.The term DCM includes a range of devices from traditional traffic counters on the simple end, to more complicated devices such as weigh-in-motion field units. This document defines individual parameters that represent t
45、he configuration, status, and control information that are unique to DCMs. This document also defines specific groupings of these parameters and others to address the operational configuration, monitoring, and control of the device in a baseline system configuration. There are four annexes to this d
46、ocument. Annex A is normative; all other annexes are informative. This document is an NTCIP Device Data Dictionary Standard. Device Data Dictionaries Standards definemanagement information in terms of objects (data elements, data frames, and messages) for use within NTCIP systems. A Joint NTCIP Devi
