The Messenger Host Terminal is the focal point of any Messenger System. It is simple to install and use with a variety of useful features to enable quick response to alarm conditions detected at remote sites. Hardware requirements are as follows:
The Host Application is a bespoke software program written in C++
which provides the user friendly intuitive MMI for the Messenger
System. The Host Application offers the following main facilities:
Remote Site Monitoring Features
Meter Reading Features
Host terminals are available for
Messenger / Waste Watcher / Agri-Trak / PD2 / PD3 and PD4 remote site
monitors. The Host Station consists of the Host Application running on
a standard PC and communications hardware as required (PSTN landline
modems, GSM modems).
The host terminal system for monitoring the Messenger / Waste Watcher / Agri-Trak / PD2 / PD3 and PD4 remote monitoring devices ranges from a single stand-alone PC with a single PSTN modem displaying status information, through to a full client/ server system with a central industry standard data storage system (such as Oracle, Sybase SQL Server) with multiple communication gateway terminals, each equipped with up to 16 modems or suitable communication devices (Kilostream, Trunked Radio, GSM Terminal) and multiple client terminals for displaying information to the user.
The actual status display software is available in a variety of formats for displaying information in a format that most suits a particular customer's needs. Each terminal is highly configurable to tailor the facilities to specific user requirements and, in large systems with multiple client terminals, individual terminals can be configured to monitor and report on specific sections of the monitored system. Most client terminal types have the ability to view an historical archive of reported events and the ability to configure the database information fields stored for each monitored unit to suit the user's requirements.
Additional software packages are available as part of the host terminal system (when operating in a client / server configuration) to provide other facilities such as generation of statistics (e.g. Customer Minutes Lost figure when the system is used to monitor the electricity distribution network) or to interface to other systems that a customer may have in operation.
A mixture of Messenger Units can be monitored from a single system.
