VIII. Connecting to the Software:
Important: This data logger supports an Auto Baud Rate Mode which automatically
detects the communication speed. 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. If you cannot connect to the
logger and suspect that the logger may be using a fixed rate mode; try each
connection speed separately, especially 38400 which is required when using the
Global Access software. Direct connection is made through the USB port.
To connect to the logger, click the “Direct” option and from the “Port” menu, 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”.
Next, select the desired baud rate from the “Baud Rate” menu. Generally, the
recommended rate of 57.6K baud is used although; long cables or other factors may
require a slower setting. Click “Connect” to make the connection. If a connection is
not made, an error message will appear. Check the battery, communication cable,
driver installation and COM port settings.
