Model 106-L Ozone Monitor Manual Rev. E

5. In Parenthesis, next to the “USB to UART” listing is the assigned COM

port number. This number will be used for the settings for the 2B Tech
software or terminal emulator used to read data from the Model 106.

Using the Connection



Plug the USB cable in after the powering the Model 106 to ensure correct

functionality.



When setting up your software or terminal emulator, choose the correct

com port listed in the Device manager.



Use these baud rate settings: 2400, 8 bits; no parity; 1 stop bit.



Use 2B Technologies Display and Graphing Software (free download

from

http://twobtech.com/software.htm

) to read measurement data from

the Model 106.
