adapter that supplies 14 volts in
order to supply enough power to
the pressure sensor. I used a 12 volt
unregulated AC adapter for this.
When you apply power to the 5V
regulator, the LED on the regulator
should light up. If it does not or is
very dim, then you have a bad power
connection somewhere. Disconnect

the power immediately.
The DiosPro ships with a test
program installed on the chip. When
power is applied, the status LED
should blink. This indicates that the
chip is getting enough power.
In order to program the DiosPro
chip, you need an RS-232 adapter
to connect the chip to your PC.
These are available from the
Kronos Robotics website for under
$10. The EZRS232 interface
comes in kit form with a five-pin
male header. In order to connect
the EZRS232 to our Carrier 1, we
need to create a small adapter by
connecting two five-pin female
headers together as shown in
As an option, you may forgo the
male header and attach a five-pin
female header in its place as shown
in Figure 20. This is the preferred
method of programming the Dios
Carrier 1 when the headers are on
the top of the board.
The EZRS232 interface board is
connected to the carrier by slipping

the female header over the programming leads. These are the first five
leads on the right side of the carrier as
shown in Figure 21. You can now
connect the PC to the indoor satellite
and apply power.
If you have not already done so,
download and install the free Dios
Compiler from the Kronos Robotics
website. You can pick up a copy
Once installed, start the program
and load the code from Program
1 into the compiler and hit the
program button. The compiler should
compile the program, then upload
the code to your DiosPro chip.
Once done, the status LED will blink
and the word “test” will continue
to print on the debug terminal of
Back in March, I showed you how
to build the 1Wire temperature sensor
shown in Figure 22. Information for
this sensor is also available on the
Kronos Robotics website.
You will need one of these remote
sensors connected to
your indoor satellite.
Once built, just plug the
connector into one of
the existing sensors
mounted on the satellite.
