E-mail Alarm & Auto Report Format

The NDACS 6000 utilises a standard E-mail format for sending alarm and automatic report data. It is possible to send E-mail messages from the instrument to a maximum of 4 users simultaneously and this can be expaned using the E-mail account mail box options.. The Automatic report data files are CSV format and can be read directly by most Windows packages such as Microsoft Excel, Word etc.. Each E-mail alarm or record in the data files are time stamped and use the following data format:

Date,HH:MM:SS,Chan-0,Chan-1,Chan-2,Chan-3,.....

Figure 10 demonstrates how a large number of sensors are combined into a single instrument system. The LSI-R102 receivers can all be grouped together and only interpret signals from their specified sensors. The output from the LSI-R102 is passed to a network of NDACS loggers or NetPod 4000 instruments depending upon the application.

As long as T/S-102 sensors are deployed within the range of the receiver then data with be acquired. The T/S-102 can also be directly connected to the Keynes data acquisition systems if required.

Figure 6 and 7 shows the T/S-102 sensor directly connected to the NDACS logger for local stand-alone data recording operations. When used in conjunction with the NDACS logger a laptop PC can be used to observe real-time information and download archived data. The same real-time display is presented to the User no matter which communication interface is in use.

Figure 8 demonstrates the configuration of the LSI-R102 receiver unit and NDACS logger units for use as a remote stand-alone recording system. The instrumentation can be configured to report automatically via a dial-up Internet link or directly by a data server. A wireless modem can be used when a standard telephone line is not available.

Figure 9 shows details of the E-mail automatic data report that can be sent directly from the Keynes Controls instrumentation without the use of a local PC.

The following pages demonstrates how the T/S-102 sensors are deployed to form local systems with direct connection to a data acquisition or logger unit, distributed systems where the sensors are connected to the logger unit using the radio interface and widely distributed applications where sensors are deployed at different

locations on the same site but a long way from the data logger and finally multiple sites using many sensors connected to a logger unit with the data reported automatically across the Internet. It is also possible using Keynes data acquisition systems to read data from multiple sites anywhere in world as long as an Internet connection is available.
