Viewing Real Time Data on your PC
Real Time data from your Sportsman data logger can be displayed and recorded on your PC computer using the
DataLink II program. Before you can view the data however, you must first setup the real time parameters in
your data logger. To setup your data logger’s real time configuration, open your configuration file, and right
click on the Sportsman channel button. An edit dialog box will be displayed. In the center of the dialog box will
be a Real – Time Telemetry Section.
Setting up the Logger Real Time Telemetry Parameters
This section will contain two lists. The list on the left-hand
side of the telemetry section will include all of the data
channels currently being monitored by your data logger. The
list on the right-hand side of the telemetry sections includes
all those channels that will be displayed during a real time
telemetry session.
To add a channel to the telemetry list, highlight the name of
the channel in the left-hand list, and click on the right arrow
button to add the selected channel to the real-time channel
list. To remove a channel from the real-time channel list
highlight the name of the channel in the right hand list and
click on the left arrow button. Remember that only channels
in the right hand list will be displayed during a real time
telemetry session.
From the options list in the lower left-hand corner of the dialog box, select the
Real Time Sample Rate
and
select the desired real time sample rate.
Note:
the V-Net Sample rate of each module(s) to be monitored, should
be equal to or greater than the real time sample rate. If they are not, then the last data points will be repeated
during the sample process.
Next, select the
Real Time Communications Port
option and type in the name of the serial communications port
on your PC you will be using to receive the real time data from the V-Net system.
Normally this is the same as the default Logger Com Port setting in the initial software installation. Normally this
is COM1.
After you have edited the options, use the
Send Configuration
button to sync the setup data to your data logger.
Next, select
OK
to exit the edit box. You will need to turn the power to your data logger “Off”, and then back on
to allow the changes to take effect. When you have completed the edit, save the configuration file.
Entering the Datalink Real Time Telemetry Parameters
The final step to setting up the real time telemetry session is to set the DataLink II real time recording parameters.
These parameters are set by selecting the
Recording Parameter
menu item found in the
Telemetry
main menu
selection. The following dialog box will be displayed.
The first parameter
Circular Buffer Length
is used to set the amount of data to record in seconds. The
Recording
Mode
is used to determine whether the recording will stop when the maximum record time is reached or whether
the oldest data will be overwritten. For example, if a 1000 seconds is entered for Circular Buffer Length and
Stop
after reaching end of buffer
is selected, the program will record data for 1000 seconds and stop. If
Continue
until stopped manually-overwrite oldest data
is selected, the program will continuously record until stopped by
the operator. Only the last 1000 seconds of data will be stored.
