Communication Setup
You set the OaktonLog up for recording, saving, downloading,
and viewing the data from your computer. Connecting the
OaktonLog to the computer is a 3-step operation:
1. Hardware connection Ð Connect the OaktonLog to the
and viewing the data from your computer. Connecting the
OaktonLog to the computer is a 3-step operation:
1. Hardware connection Ð Connect the OaktonLog to the
computer.
2. ÒWake upÓ the OaktonLog Ð Open the OaktonLogÕs COM
port for computer communication.
3. Software Connection Ð Establish a connection using
MicroLab.
Hardware Connection
In your OaktonLog PC connection kit you will find a serial cable.
One end of this cable connects to an empty serial port on the
back of your computer. Note that you may need to use a 9/25-pin
adapter (this applies mostly to non-Pentium computers).
Connect the other end of this serial cable to the computer
connection socket on the back of your OaktonLog device.
ÒWake upÓ the OaktonLog
Since communication depletes battery life, the OaktonLog device
is not generally open for communication. If you wish to transfer
data to and from the OaktonLog, you have to first open the
computer connection port manually by pressing both of the
OaktonLogÕs keys simultaneously. The OaktonLogÕs LCD displays
the status of the device, and from that moment the PC connection
port is open for transmission. The port remains open for 4
minutes. Please find the scheme of this procedure at page 12.

Note: Communication between the PC and the OaktonLog
device requires a free serial port.
Software Connection
In most cases, the OaktonLog will automatically connect to the
software. You should be able to proceed to setting up the
OaktonLog parameters (page 3) or downloading data (page 4).
If there has been a communication
problem or you have changed ports
click the Connect icon on the left
toolbar. The Comm Setup dialog
box opens. This dialog box
indicates which of the four possible
serial ports on your computer are
available for communication. Note
that in the dialog box above COM 1, 2 and 4 are available for
communication.
If none of the four boxes in the Comm Setup dialog box is
checked, you must open a serial port in your BIOS configuration.
If you do not know how to open a serial port on your computer,
refer to your computer vendor.
By clicking the Try to connect button, MicroLab establishes a
connection with the OaktonLog. The Connected window opens.
Click OK - the OaktonLog is now ready to communicate with the
computer. Once a connection is established
with the OaktonLog, you can perform all
operations from the MicroLab software. The
following section provides additional
information regarding various MicroLab
features.

Setting up the OaktonLog
Data-Recording Setup
All data recording parameters are configured from the right panel
of the MicroLab software.
Stopping the OaktonLog
Before setting up the OaktonLog, you must stop the
current recording run.
All data recording parameters are configured from the right panel
of the MicroLab software.
Stopping the OaktonLog
Before setting up the OaktonLog, you must stop the
current recording run.
To stop recording data, make sure the OaktonLog is connected
to the cable, and that its communication channel is open. Click
the Stop icon on the left toolbar. The OaktonLog stops recording
data.
Sensor selection Ð The upper part of the right
tool bar is used to select the sensors to be
used in the next recording. These are
temperature, humidity, and external
temperature sensor. Click the button at left of
temperature icon to select
to the cable, and that its communication channel is open. Click
the Stop icon on the left toolbar. The OaktonLog stops recording
data.
Sensor selection Ð The upper part of the right
tool bar is used to select the sensors to be
used in the next recording. These are
temperature, humidity, and external
temperature sensor. Click the button at left of
temperature icon to select
°
F or
°
C.
Clicking one of the sensor icons with the left
mouse button selects the corresponding sensor for the next data
logging. A selected sensor shows a red light next to it. Otherwise
the circle next to the icon will appear black. To the right you see
only the internal temperature sensor selected, while the two other
ones are not.
Some models do not include the humidity sensor. In those cases
the Humidity sensor icon is
disabled. When you select the
humidity sensor, you may
calibrate it through the Microlab
software as follows:
Click the arrow to the left of the
Humidity sensor icon. The
Calibrate dialog box opens.
Make sure that the OaktonLog
has been stopped (i.e. it
measures, but doesnÕt save the result in its memory).
Measure the humidity in two known values (e.g. 23% and 75%).
Fill in those values together with the values the OaktonLog is
showing.
Click Calibrate. The OaktonLog takes about five seconds to
calculate the new linear conversion for the relative humidity. After
the OaktonLog finished the calculation, the Calibration dialog box
closes.
Sample interval Ð This digital display
is used to determine the amount of
time between every two samples taken
by the OaktonLog. To change the
sample interval, simply click on the
digit that you wish to change. A click
on the left mouse button makes the digit rise by one unit. A click
on the right mouse button lowers it accordingly. The largest
sample interval is 120 minutes and the smallest one 10 seconds.
The picture to the right shows a sample interval of 10 seconds.
Start Time Ð You may set the
OaktonLog to start the data recording
at a predetermined date and time. This
is done by changing the Start Time
display. By default, the start time is set
to your current time and date. A click
on the left or right mouse button on
time and date changes it to the start time of your choice. If you
want to return to the default time and date, click on the small reset
button. In the picture above, the starting time was set to 7:49 PM
on February 14th, 2001. The number 01 refers to the year 2001.
Cyclic Run Ð A cyclic run means that
when the OaktonLogÕs memory is full, it
overwrites older samples starting with
the oldest one. Click the Cyclic run
indicator with the left mouse button to
select a cyclic run for the next data recording. This picture shows
that the Cyclic run has been selected for the next data recording.
Send Ð After setting recording parameters you must send these
settings to the OaktonLog using the Send Icon. The arrow of the
Send icon is empty (wire) by default to indicate that no changes
