Ludlum Model 375NET-32 Area Monitoring System

The Ludlum Model 375 Network Software allows a PC equipped with multiple serial ports to monitor up to a quantity of 32 Ludlum Model 375 Digital Area Monitors. Data, containing radiation levels and status, can be logged to a file at user-specified intervals. E-mail or pager messages can be sent out during alarm and/or failure conditions. Data can be displayed in a grid, a graph, or in a map view. Data is saved to a Microsoft Access database and to an ASCII file if desired. Queries can be made, for example, to locate alarms over the past week. The use of this software and versatile area monitors creates a very powerful yet inexpensive system.

CONNECTION: When only 1 or 2 units are connected, they can be connected directly to the PC COM ports. When 3 or more units are connected it is suggested that connection be done through the USB port via a USB to RS-232 converter.
COMMUNICATION: The Model 375 outputs data every 2 seconds and the software displays the data and logs the average readings to a database at user specified intervals.
DISPLAY: The main screen displays the 32 channels and the status of each channel. Below each channel are 2 indicators that show when data is received from the Model 375 and when the data is logged. The background of each channel indicates the status of the Model 375.
DATA LOGGING: Each channel can be independently logged at user specified intervals. There is the ability to log data when the reading exceeds a user-defined value. The database stores the channel name, date, time, reading, status, and a user defined comment. The data can be viewed from within the program or in Microsoft Access.
GRID/GRAPH VIEW: The current or logged data can be viewed in a graph or data grid. It is possible to query the data by date, time, reading, or status.
MAP VIEW: Each channel can have a user-defined name. There is also a user-defined comment field available for each channel. A bitmap image can be imported in and used as a location map. A built in editor allows for individual placement of the channels on this map. The map can be scaled to 25%, 50%, 75%, or 100% size.
E-MAIL SUPPORT: When an alert, alarm, or error event occurs, the software will send an e-mail to 8 user-defined e-mail addresses. There are 8 e-mail addresses for alarm/alert conditions and 8 e-mail addresses for other conditions (overload, detector fail, off-line, error). It is also possible to specify a time range for sending e-mails so that, for example, during working hours the e-mail goes to 1 set of addresses and then at night goes to another set of e-mail addresses.
COMPUTER:A Windows-based PC with multiple serial ports is required. LMI will provide interface computers and/or a complete turnkey computer solution on request.
