Datalogger Product Description
The GL500-2-1 Datalogger is the latest addition to Global Water's line of rugged remote dataloggers.  The dataloggers feature two analog channels and one digital channel for recording data, as well as monitoring battery voltage.  The datalogger records over 81,000 readings and has four unique recording options: fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception.  Start and stop alarm times can be programmed to synchronize multiple dataloggers, delay sampling until a preset time, or limit the number of recordings during a day.  The dataloggers are available for computers with either a RS-232 serial communications port (GL500S-2-1 version) or a USB port (GL500U-2-1 version).

Remote Monitoring
The GL500-2-1 dataloggers can monitor two 4-20mA sensors (0-5 volt inputs are available as a factory option) and features a scalable digital input that accepts switch closure signals from rain gauges or relays, as well as pulses from various external monitoring and control devices.  The datalogger provides switched power to the sensors based on the programmable sample interval and sensor warm up time settings.  2-wire and 3-wire sensors can be quickly connected to the datalogger's internal terminal strip and calibrated via the Global Logger software.  The GL500S-2-1 Datalogger Serial Communications version can be accessed through dial-out to a remote modem attached to the serial communication port.

The GL500-2-1 dataloggers include Global Logger II Windows software and PDA software, which allow for easy setup, calibration, upload, and transfer to a spreadsheet program using a laptop, desktop, or PDA.  The Global Logger II Windows software has online help files that are easily accessed using drop down menus and links to quickly find the answers to your questions.

Please note: The Global Logger PDA software, included with the datalogger, does not support the Palm operating system.  For more information on supported PDAs click HERE.

Bluetooth Capability
The AK1500 Bluetooth Adaptor was designed to eliminate the need for custom PDA cables to communicate between your PDA and the GL500S-2-1 Dataloggers.  The adaptor connects to the datalogger's serial port using the same interface cable provided with the software-cable kit.  The interface operates from a single 9 volt battery and is turned on automatically when the cable connects the datalogger and Bluetooth adapter.  Because the Bluetooth module consumes power when turned on, it is recommended that the cable be disconnected from the datalogger when not in use.  A red LED shows the power status and is on continuously while the adaptor is plugged into the datalogger.  There is also a blue LED that shows the status of the Bluetooth connection.
