Figure 4-38. File Options
4.4.13 Attach Option
The Attach option shown in Figure 4-39 allows the “
W
ATER
LOG” software to work in a
stand-alone mode or while connected to the sensor.
To use the attach option, the sensor must be physically connected to the serial port of the PC. The
“
W
ATER
LOG” software is expecting a mouse (if used) to be on COM port 1, and the sensor to
be connected to COM port 2. The action behind the “Attach” option is a software issue that links
the PC “
W
ATER
LOG” software to the software in the “
W
ATER
LOG” sensor, so even though the
sensor may be connected to the PC by a cable, they may not be “attached”.
When attached, all changes are sent to the sensor as the changes are made on the computer.
Sensor status information will be updated every 5 seconds. The “Working” message will be
displayed in the message box on regular intervals.
If the sensor is not connected to the PC, the software is forced to the stand-alone mode.
