Setup the NOMADTMDATALOGGER

NOTE: Close all programs before launching the

NOMAD Datalogger.
Attach the NOMAD to an available Serial port of

your computer using your RS-232 cable
purchased with your unit (see ordering block).

If you wish to use the external RTD sensor with
Temp dataloggers only, plug it in to the “Temp
Probe” socket on the NOMAD.

From the Windows program manager select the
NOMAD icon and start the program. The NOMAD
Datalogger main menu screen will appear.

Choose “COM port” from the “Setup” menu to
set and test serial communication with the
datalogger.

NNOO TTEE::

If NOMAD is not connected, an error message
“Port is available, but no NOMAD was detected” will be
displayed. Check cable connections and COM port settings
on your computer. Select “Setup” again to test
communication. If you still get an error message, choose an
alternate COM port setting.

Once successful, you will be greeted by the
“NOMAD Launch Utility” screen.

Follow your application requirements in choosing
the appropriate menu item, using on-line help as
needed.

Readout and Plotting

Shutdown any unnecessary programs before launching the
NOMAD Data Logger, especially programs that would be
busy processing data (and using much CPU time).
Otherwise, the NOMAD Data Logger may not launch
properly.

Run the NOMAD Launch Utility. Change the CommPort
number if necessary. The Comm Port setting will be stored
and then retrieved upon subsequent executions of the
NOMAD Launch Utility.

After successfully completing a communication test the
NOMAD datalogger can be launched. Choose "Configure &
Launch Datalogger" from the "Logger" menu. The program
establishes a serial link with the NOMAD and opens the
"Launch the Datalogger" dialog window.

You can enter up to 48 characters of arbitrary descriptive
text to the "Memo or Description" entry box. This text is
saved in the NOMAD memory during the launching process
and then retrieved along with the recorded data during the
readout process.

There are 4 different ways to start data recording.

1. Now.

2. At time specified below.

3. When button on datalogger is pressed.

4. After delay starting when button is pressed.

There are 2 different data recording options when the
NOMAD memory is full. The NOMAD may either stop
recording data or it may start overwriting the oldest data. In
addition, The datalogger stops recording when it is

connected to the computer, and the computer begins data
readout or tries to launch the NOMAD again. In the latter
case, new data starts filling the memory from the beginning,
overwriting the previous record.

By pressing the "Sampling Option" pushbutton you can
choose to record maximum, minimum, average, or one
sample every interval. If maximum, minimum, or average is
chosen, the datalogger takes 4 samples over the interval
and uses these 4 points for the maximum, minimum, or
average calculation. The "Sampling Interval" pushbutton
allows you to select the interval at which the data is
recorded. The highest sampling rate available internally is 1
sample per second. This means that the minimum sampling
interval is 1 second for sampling option set to "single", and
4 seconds for the other sample options. If you select a
sampling interval of less then 4 seconds, and then select a
sampling option of minimum, maximum or average, the
program will automatically adjust the sampling interval to 4
seconds. The displayed total record length indicates the
recording time available until the NOMAD memory is full.
This number depends on the memory size and sampling
interval.

The displayed NOMAD Version Number is a firmware
version number which allows you to distinguish between
subsequent versions of the datalogger. Sample capacity
indicates the amount of memory available. The system time
is the computer current time. The NOMAD automatically
sets its clock by reading the time from the computer. If the
computer time is incorrect, use the appropriate Windows
commands to set the computer clock.
