Download Data

Whenever data is received from the TriLink, it is accumulated and displayed
automatically by MultiLab. There are two modes of communication: Online and Post-
Experiment.
Online communication
When TriLink is connected to the PC and programmed to run at sampling rates of up
to 100/s, TriLink transmits each data sample immediately, as it is recorded, to the
PC. The software thus displays the data in real-time in both the graph window and
the table window.
When TriLink is connected to the PC and programmed to run at a sampling rate of
500/s or 1000/s, TriLink transmits every twentieth or fortieth data sample online. This
means MultiLab displays data at a rate of 25/s, while the full data is accumulated in
TriLink's internal memory. Once the recording has ended, the full data is
automatically downloaded to the PC and displayed.
When TriLink is connected to the PC and programmed to run at a sampling rate of
11,200/s or 20,800/s, data is accumulated in TriLink's internal memory. This data is
not transmitted to the PC until the recording period has ended, when the data is
automatically downloaded to the PC and displayed.
Off-line data logging
To download data that was recorded offline, or while TriLink was not connected to a
PC, connect TriLink to the computer, run the MultiLab program and click Download
on the toolbar. This will initiate the Post-Experiment Data Transfer
communication mode. Once the transfer is complete, the data will be displayed
automatically in the graph window and in the table window. If there are several
experiments stored in the TriLink, the first download will bring up the most recent
experiment; the second download will bring up the earliest file, the third download will
bring up the second earliest file, and so on.
To download a particular experiment, choose Selective download from the Logger
menu, then select the experiment's number in the Download dialog box.
Click Cancel in the Download progress window at any time to stop downloading the
data.

Save Data

Click Save on the main toolbar to save your project. This will save all the data
sets, graphs, tables and video movies under one project file.
Saving the project will also save any special formatting and scaling you did.
If you made any changes to a previously saved project, click Save to update the
saved file or select Save as... from the file menu to save it under another name.
Note:
To delete a specific data set, a graph or a table from the project, use the
Data Map (see page 96)
To remove unwanted data from a specific data set, apply the crop tool
(see page 139).
