Quick Start
- Install ôNOMADö software:
DOS version: insert diskette in floppy drive. At the DOS prompt
type A:\INSTALL and press enter. If floppy drive is B, then at DOS prompt
type B:\INSTALL followed by enter.
Windows version: Before installation, all programs must be closed
and ensure that terminant resident (TSR) programs are turned off. These
programs have been found at times to conflict with the installation process.
Insert diskette into floppy drive, from file manager choose File, Run.
Type A:\SETUP and press enter. Use B:\SETUP if floppy is the B drive.
Macintosh version: insert diskette into floppy drive, drag the
NOMAD Datalogger folder onto your hard drive.
To start NOMAD, open the Nomad 
Datalogger Folder, and doubleclick on the NOMAD icon.
Verify your computer clock is set to correct time, since
NOMAD obtains its time stamp from your computer.
To start NOMAD
for Windows,
inside Windows click on the NOMAD Icon.
To
start NOMAD in DOS, type cd:\nomados and press return. Then
type NOMAD and press return.

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 sensor with Temp dataloggers only, plug it in
to the ôTemp Probeö socket on the NOMAD.
From program manager select Nomad icon. Cancel ôabout the dataloggerö
screen by keyboard return or select æOKÆ button.
The Nomad Datalogger screen will appear. Select logger sub-menu, ôconfigure
and launch dataloggerö.
NOTE: If NOMAD is not connected, an error message ôPort
is available, but no Nomad was detectedö will be displayed. Check hardware
connections and select ôCOMPORTö under the ôSetupö menu for alternate
ports to test. Once successful, you will be greeted by the ôLaunch dataloggerö
screen.
Follow your application requirements in choosing the appropriate menu
item, using on-line help as needed.
