T

RAK

 monitor comes with special software called T

RAK

P

RO

TM

 

Data Analysis Software, which is designed to provide you with maximum 
flexibility and power when using the D

UST

T

RAK

 monitor. The following 

sections describe how to install the software and set up the computer.

 Data Analysis Software 

T

RAK

P

RO

 software contains a very comprehensive Help Function. This 

utility provides all the necessary information to guide you in all aspects 
of software operation.  

 

Connecting the D

UST

T

RAK

 Aerosol Monitor to the Computer 

Each D

UST

T

RAK

 monitor comes equipped with an RS-232 cable and a 

25-pin to 9-pin serial cable adapter. One end of the cable is a 25-pin D 
subminiature connector labeled COMPUTER; the other end is an RJ-45 
modular connector that connects with the logging instrument. Serial port 
connectors always have pins (male) on the computer side. 

1.  Locate an available serial port on your computer: COM1, COM2, 

COM3, or COM4. 

2.  If the port has a 25-pin connector, you do 

not

 need the adapter. If 

the port has a 9-pin connector, plug the 25-pin end of the adapter 
into the RS-232 cable. 

3.

 

Connect the RS-232 cable to the available serial port on your 
computer. 

4.

 

Connect the RJ-45 connector to the D

UST

T

RAK

 monitor. 

 

Set-Up the Communications Port 

To communicate with the D

UST

T

RAK 

monitor

, 

the software must be 

configured for the proper COM port. The T

RAK

P

RO

 software can be 

manually set to operate on a specific COM port, or it can automatically 
find a D

UST

T

RAK

 monitor that is attached to any COM port. To set up 

the COM port, do the following:  

1.

 

Turn on the D
