However; this communication software also supports loggers which may be programmed in a Fixed Baud Rate Mode. This is useful in telemetry applications, particularly when using Global Water data loggers with our Global Access radio modem software. The upcoming discussion assumes that the logger is programmed in auto detect mode. -
Page 9: Modem Connection
Global Water 800-876-1172 • globalw.com To make a direct connection to the logger, click the “Direct” option and from the “Port” menu, select the port you wish to use. For USB access (GL500U) select the USB serial port at the COM port the driver was assigned, which is automatically shown in the list as “Global Logger USB Device”. - Page 10 Global Water 800-876-1172 • globalw.com GL500S Only settings must be made to the remote modem and an initialization file may be required to properly configure the host modem. Two baud rates are supported 9600 and 19200. Should you experience difficulty establishing a reliable connection at 19200, try the slower connection speed.
- Page 11 Global Water. The remote modem is configured by setting DIP switches. They should be set to auto-answer on, DTR Normal, carrier detect normal and smart mode. Global Water can provide external modems and interface cables at an additional cost if requested.

Page 12: Main Screen
Global Water 800-876-1172 • globalw.com Main Screen: The main screen is where the status and option menus are accessed. The data logger will continue to log at normal intervals while connected to the Global Logger software. While connected, the logger will draw an addition current from the power supply of 5-10mA so it is advised that, if you plan to not access the logger for extended periods of time, you disconnect to increase battery life. - Page 13 Global Water 800-876-1172 • globalw.com Tool Bar: The tool bar at the top of the screen has 3 options; File, Action and Help. In this screen, the File option is used to exit the program only. Action allows a menu driven interface to the various functions and displays the hot-keys, which can be used for fast access.
- Page 14 Global Water 800-876-1172 • globalw.com Records: This field indicates the number of data recordings in memory. Logging State: This shows whether the data logger is currently logging or waiting to be started or stopped by the alarm timers. These features are described in detail later.
- Page 15 Successive numerical readings taken by using Sample Continuously or Get Sample are shown in a list below the bar, up to 5. Pulse channel: The GL500-2-1 Data Logger has one pulse channel with a maximum count of 65,535. At the time of the logger’s normal sampling interval, the counts are stored in memory along with the other sensor data and time stamp, and then the counters are set to zero to start the counting sequence over again.

The logger will start at the next occurrence of the Alarm 1 time and stop at the next occurrence of the Alarm 2 time after the Alarm 1 timer has expired. - Page 23 Global Water 800-876-1172 • globalw.com The calibration of channel one to a water level sensor is discussed in the following example where it is not possible to calibrate the sensor over its full range. The water level sensor shown is designed to measure over the range of 0-15 feet but a water column of 15 feet may not be available.
- Page 24 Global Water 800-876-1172 • globalw.com Disp High: This field sets the upper limit of the bar graph displayed in the main screen and provides a way of scaling the graph beyond the upper limit used to calibrate the logger. In this example, the upper calibration point was a water level of 8 feet but the maximum range of the sensor is 16 feet.

Global Water 800-876-1172 • globalw.com Click on the Low EU field and enter the low engineering unit that will be used to calibrate the logger, not necessarily the lowest reading the sensor can output. In this example, the value is zero feet, which is the lowest calibration point and water level. - Page 26 Global Water 800-876-1172 • globalw.com Enable: Checking the Enable box allows the display of the data for that channel in the historical record. The pulse channels are always being monitored and the counts between sampling intervals stored whether they are enabled or not.
