Procedure for Programming Version D Circuit Boards 

Date: 1 July 2006

Author: Craig Williford

Requirements
Programming the ozone monitor requires a computer running the "Analog Devices Serial 
Downloader" program to download the firmware from the computer to the ozone monitor, 
and the rs232 serial cable provided by 2B Technologies. The computer must have a 
serial port or a USB port with a USB to Serial converter cable to connect to the rs232 
serial cable provided by 2B Technologies. 

Procedure
1. Download the Widows Serial Downloader provided by Analog Devices from the 
website: 
ftp://ftp.analog.com/pub/www/technology/dataConverters/microconverter/wsd_v6_7.exe. 

2. Install the Windows Serial Downloader by starting the executable file you have just 
downloaded. 

3. Start the Windows Serial Downloader program that you just installed. 

4. Connect one end of the serial cable provided by 2B Technologies to serial connection 
on rear side of ozone monitor and the other end to the computer. Or if the computer does 
not have a serial port, connect the other end to the USB to Serial converter cable. 

4. Remove the top cover of the ozone monitor. Instructions for removal are located in the 
ozone monitor manual. 

5. Locate the small buttons labeled “sw1” and “sw2” on the circuit board inside the ozone 
monitor.

 6. Turn on the ozone monitor. 

7. Press and hold the switch labeled “sw2”. While holding “sw2” down, press and 
depress the switch labeled “sw1”. Now release “sw2”. This will enter the board into 
“Serial Download Mode”. 

8. On the computer running the Windows Serial Downloader, locate the “Reset” button 
on the program’s window. Press the “Reset” button. If the board is connected correctly 
and in “Serial Download Mode”, you will see this message: 
“Configuration: COM1, 9600 baud 
RESETTING PART: OK” 

*If you do not see this message, repeat steps 7 through 8 until you see the correct 
message 

9. Press the “Download” button located on the Windows Serial Downloader. This will 
bring up a window prompting you to choose the file with a .hex extension to be 
downloaded. Find the .hex file that was provided by 2B Technologies and select it. A bar 
will appear showing the status of the download and the download should only take a few 
seconds. 

10. The Board is programmed! Turn the ozone monitor off and on again to start the new 
program. 

11. Enter the menu of the ozone monitor and re-enter all of the parameters (Averaging 
time, Calibration parameters, External, Baud Rate, Units). You must do this because the 
internal eeprom memory is cleared when the microcontroller is reprogrammed. 

Note: If step 8 is unsuccessful, please submit a tech support ticket on our website under customer support for further assistance.
