EW Windows Uploader - Model D Logger Main Window

When a model D logger is connected to a port opened by EW Windows Uploader the program uploads the list of traces in the logger and other information then displays the appropriate Logger Main Window.

When other logger models are connected a slightly different window is displayed: Models A, B and C Logger Main Window.

Logger Traces

The trace list at the top of the window shows, for each trace in the logger's memory, most recent trace first:

• The sequence number of the trace.
• The date on which the recording of the trace was started, in ISO 8601 format. That is, year, month and day order.
• The time at which trace recording was started.
• The time at which trace recording ended, which may or may not be on the same day as the start of trace recording.
• The user number of the trace - that is, the user number setting of the logger at the time the trace was recorded.
• "(Uploaded)" if the trace is flagged in the logger's memory as having been uploaded.

Upload Trace starts the upload of the trace selected in the trace list. The upload process is described in more detail under Trace Upload Process.

Clear Memory... clears the logger's trace memory after displaying a confirmation dialog box. It does not affect the settings such as the sample interval, user number or task declaration.

Logger Settings

The Logger Settings box displays a few of the key pieces of information in the logger:

User Number

The user number which is used to help identify traces recorded.

Battery

The current voltage of the logger's internal battery.

Clock

The time shown on the logger's internal clock relative to the clock of the computer.

Sample Interval

The interval between altitude and GPS samples which will be used in any traces recorded in the future. This is in seconds.

Settings... displays a window which allows various settings in the logger to be changed. This is described under: Model D Logger Settings Window.

Set Clock... sets the logger's clock to be the same as that of the computer. Note: this will invalidate any traces currently stored in the logger so don't use it until valuable traces have been uploaded. For this reason, there is a confirmation dialog box displayed before the operation is carried out.

Refresh Display

The Refresh Display button causes all of the trace and settings information to be read from the logger and redisplayed. The Logger Main Window closes then a few seconds later, another window of the same type is opened.

Close

The Close button closes communication with the logger by sending it a command to switch itself off and closes the logger main window. The serial port is left open, waiting for another logger to be connected and switched on.
