Web Interface

The NDACS 6000 contains an embedded Web interface enabling the configuration of all instrument operations to be carried out using a standard Web Browser no matter which communication interface is being used. The User Interface is the same no matter if the connection to a system is made via the Internet or dial-up telephone connection. Any computer using a modern operating system will be able to examine data without the need for any third party applications software.

Status Messages

A series of status messages can be sent at preset time intervals or when the instrument restarts to indicate that the system is alive and functioning correctly. These messages are useful to show that the instruments are working when deployed remotely or when waiting for a specific in frequent event to occur.

Data Logging Operations.

The NDACS 6000 family of loggers supports 2 independent data loggers. An event logger capable of storing 1 million records used to detected a defined event, and a general purpose recorder that can stores data at preset intervals.

Internet Connectivity

The NDACS 6000 loggers supports all the network operations  required to transmit data across the Internet.  A  multiple level  password system ensures that data and instrument configurations stay safe when operating on an un-secure network. Can be fully configured and results displayed on the web interface. Data is reported automatically after a preset number of records,  data recorded up to a specified date or time and upon detecting a specified event.

The NDACS 6000 family of products offers both real-time data acquisition and data recording in a single easy to configure device. The NDACS 6000 can be deployed for stand-alone operations and will report data automatically by e-mail across a suitable network or allow remote access to view results in a web browser. The instrument can be connected to a network and results read in real-time using the freely available driver software.
