RACEAIRTMREMOTE INSTRUCTIONS
Computech’s RaceAir Remote Competition Weather Station consists of; the RaceAir Remote Sensor
Assembly, the Computer Interface, the Weather Pro software, the interconnect wiring, and a user supplied
IBM compatible personal computer (PC) using Windows 95 or newer operating system. The computer must
have a 9 pin serial port available to connect to the RaceAir Remote Computer Interface. The system will
automatically sample the current weather conditions and record the information to the PC. Monitoring and
recording trackside weather conditions has never been easier.
Features & Abilities:
Heat and moisture resistant sensor assembly for prolonged sampling
Log and graph weather data in real time
Perform multiple calculations automatically
Collected data can be saved to a file for future reference
Weather data and calculations are displayed in graph mode
Graph ranges, scales, and variables are customizable
Tracks high and low values for collected and calculated data
Logged data can be printed in log or graph form
Graphs can be "stamped" with text to mark events

INSTRUCTIONS
RaceAir Remote Sensor Assembly Installation:
The heat and moisture resistant Remote Sensor Assembly should be mounted in a location to duplicate
track conditions as closely as possible. The assembly can be mounted on a vertical surface, stand, or
pole. Avoid mounting the Sensor Assembly near large dark surfaces that radiate heat or in an area where
vehicle or generator exhaust gases will influence it. A mounting bracket is included in the kit. A mating
bracket is attached to the Remote Sensor Assembly. This mounting system is intended for quick
attachment of the Sensor Assembly to the mounting surface or pole. The RaceAir Remote Sensor
Assembly should be removed and safely stored for transport and during heavy rains. The kit includes an
extension cable to connect the Remote Sensor wiring harness to the RaceAir Remote Computer
Interface.
RaceAir Remote Computer Interface Installation:
The Computer Interface is a junction and switch unit with a serial port adapter and an AC power supply.
Install the serial port adapter on the computer COM port. Connect the RJ-11 cable to the serial port adapter.
Using the extension cable (4 wire cable with rectangular connectors), connect the RaceAir Remote Sensor
Assembly to the Computer Interface. Insert the AC power supply plug into the round port on the back of
the Computer Interface unit. Plug the power supply into a 110V source.
Weather Pro Software Installation:
The Weather Pro software is supplied on a CD-ROM. Start Windows and insert the CD into the disk drive.
The install process should start automatically. Follow the on screen instructions. If the program does not
auto run, click the Start button on the Windows desktop screen. Click Run. And on the command line type
D: setup and then click OK. Follow the instructions on the screen to complete the software installation.
The software will automatically place a Weather Pro short-cut icon on the Windows desktop screen. To
start the software simply double click on the Weather Pro icon. The system requires the PC to be running
the Weather Pro software continuously to log sensed weather conditions and calculated values. However,
the PC may be used for other functions with the WeatherPro program minimized or in the background.
Software Help:
The Weather Pro program includes an on-line help library that may be accessed from the Help toolbar
button, or by pressing the F1 key. There is a sample file that you may open to see exactly how the
system works. The best way to learn to use the software is by actually using it and reviewing the on-
line help.
COM Port Selection:
The serial port (com connection) must be free of other background programs that use the same port. For
example: Devices like Personal Digital Assistants or digital cameras usually have software that is running
in the background that must be closed. Make sure the Weather Pro software communications port selection

matches the port the RaceAir Computer Interface is on. Click on the toolbar button labeled COM to open
the communications port selection box. Simply click on the port in use and click OK.
System Operation:
Start the Weather Pro software. Push the red button on the Computer Interface to power the system. Single
click on the LOG tool bar button to start the logging process. Once communication has been established
with the RaceAir Remote Sensor Assembly the system will automatically open a data file name box. Click
Save to record this session. The On-line help can be accessed at any time by pressing the F1 key.
Frequently Asked Questions:
Can I plot other values on the graphs?
The Calculation Graph variables may be changed by using the Graph Data Panel. WeatherPro remembers
which values were being displayed on the graph each time you run the program.
Where is the most recent sample data shown?
The most recent sample data is displayed on the top row of the Data Grid and on the Graph Data Panel at
the lower portion of your screen.
Can I save new sample data in an existing file?
Yes. If the name of an existing file is chosen when the File Save Prompt is displayed, the
Append/OverwriteDialog is displayed providing the choice to append to the file or overwrite it. Note that
if a lot of time has elapsed, a large gap will exist in the sample data that may make the graph confusing.
How can I change the Graph Ranges/Settings?
WeatherPro allows you to customize the graph ranges and settings by selecting Ranges from the Graph
Menu. This displays the Graph Ranges Dialog. Ranges for all six graph bands may be adjusted as well as
the time interval shown.
How do I see data for a particular point on the graph?
Hover your mouse cursor over either graph. The cursor changes to a hand. Click the left mouse button and
a blue vertical line will be displayed on both graphs. The data recorded for this time slice is displayed in
the Data Grid.
What is proportional scaling?
Proportional scaling is a powerful WeatherPro feature the constantly adjusts the graph ranges to display
data collected in the most efficient manner. It sets the range for each band based on the +-2% of the
high/low recorded for the data set. For more information see: Proportional Scaling Explained.
