Digital Output (Green Wire)
The digital output is for monitoring the readings from a PC or from WB G1 LED
display. Please refer to drawing on page 2 for digital output connections via DB-9
connector to a PC. Baud rate is 9600 bps, data bits is 8, no parity, and stop bits is
1 (9600 8N1).
1- Wire the DB-9 pin numbers 2 and 3.
2- Run http://www.ontrak.net/adrcom.zip application.
3- Select and open the related port.
4- Write some letters on the black area on the software.
5- If you see a repeat of the letters, then all is correct. (When you type “A”, it
should display another “A” next to it immediately.)
If not, check to comport numbers. Go to device manager and change the port
number to something lower than 9.
We use a single-byte protocol. It is not ASCII. If it reads 1 then the device is not
ready. Otherwise, it should read 90 to 190.
90 = 9.0 AFR
190 = 19.0 AFR
147 = 14.7 AFR
This will be only for gasoline, even if you change the fuel type to others.
