DaVinci Command Protocol

The Davinci Command Protocol is a serial protocol to command various functions of the appliance. It supports

notifications for 2‐way syncronization. When used with a wired UART, the baud rate is 115200, 8 bit, 1 stop bit, and

no parity (This high baud rate allows for real‐time control of parameters).

Integration with Control Systems Some control systems may require additional programming or driver software not provided by Travis Industries. Check with your A/V Integrator to make sure that they are capable of this work. Wiring to RS232 Connector This board works with “TTL” levels. A RS232 Shifter may be needed for systems using “RS232” levels. The following example shows a typical connection to a RS232 shifter. The RS232 shifter is not included (this example was sourced at https://www.sparkfun.com/products/449 ).

Communication Troubleshooting Overview The information below illustrates how to test the operation of the DaVinci Home Automation Board and Auxiliary board for troubleshooting purposes.

Required Items

DaVinci Auxiliary (AUX) board

DaVinci Home Automation Control Board (sku# 94400141)

Power Cord with Molex Connector (sku#250-00316)

Cat 5+ Cable

USB to 5v TTL UART serial Cable Amazon Link https://www.amazon.com/EZSync-serial-TTL-232R-5V-WE-compatible-EZsync009/dp/B010K5NC68/ref=sr_1_15?ie=UTF8&qid=1549492853&sr=8-15&keywords=usb+serial+interface+ftdi

TTL Emulator software (i.e. PuTTy)

http://www.putty.org/

A PC computer with USB ports



Configuring the Hardware 1. Download and install a TTL emulator software such as “PuTTy”. PuTTy is free and able to be

downloaded at the following address: http://www.putty.org/ 2. Connect the USB to TTL cable to the terminal block of the Home Automation board as shown below.

Wire Color Location Function

Black 1 Ground

Yellow 2 Transmit

Red 3 5V +

Orange 4 Receive

Green Not Used Not Used

Brown Not Used Not Used

3. Connect one end of the CAT-5 cable to the CAT-5 socket labeled “MAIN” and the other end to the CAT-5 socket on the AUX board (see below).

NOTE: These colors are for the USB to 5v TTL UART serial Cable that is linked to in the “Required Items” list above. If using a different cable, the colors may be different.



4. Connect the power cord to the AUX board. NOTE: Do not connect the cord to 120VAC power at this time.

5. Connect the USB end of the USB to TTL cable from step 2, to the USB port on the computer you will be

doing the testing with.

6. Make sure the AUX board is sitting on a non-conductive material (i.e. wood, paper, plastic, cloth). Plug the power cord into 120VAC power.

7. Open the “Device Manager” on the computer. Select “Ports” and determine the port name for the USB port you connected to (i.e. COM 1, COM 5…).

NOTE: If you can not identify which port you plugged into, unplug the USB and the list will update. Plug the USB cord back into the port and watch the “Ports” in the “Device Manager” and see what pops up.

8. Open the PuTTy software or other TTL emulator software on the computer.



9. After opening “PuTTy” the following configuration window will open.



10. Select the “Serial” radio button. The serial line will automatically enter COM1 and Speed of 9600.

11. Enter the COM port number that you identified in step 6 in the “Serial Line” field (for this example it is

COM5).

Select “Serial”

Will default to COM1 and 9600



12. Enter 115200 in the “Speed” field. Select “Open”.

13. Check the label on the AUX board (see below). If the board is V1.30, skip this step and go directly to step

15. If the AUX board is V1.50 or above, PuTTy should be configured to set “Echo On”. This will allow you to see the key strokes that you type into PuTTys command screen.

Enter “115200”

V1.3.0 = Echo Off V1.5.0 or Higher = “Echo On”

Select “Open”



14. If the AUX board is V1.5 or higher, Select “Terminal from the left hand menu on the PuTTy Configuration screen. Next find the “Local echo” section and select “Force on”. After making the changes, select “Open”.

15. After selecting “Open” the command window the will appear. You cannot backspace or delete in this

window. You can move the cursor and type over a mistake if you make one. If you make a typing error and press “enter” the board will return an error message. If this occurs, just proceed with another command.

A. Select “Terminal”

B. Select “Force on”



16. Type the command “set flame on”. Press return.

17. The Aux board should respond with “HEY FLAME ON”.

18. Type the command “set led on”. Press return.

19. The Aux board should respond with “HEY LED ON”.

20. Type the command “set ledcolor 0,255,0,0”. Press return.

21. The Aux board should respond with “HEY LEDCOLOR RED: 0 GREEN: 255 BLUE: 0 WHITE:0”.

22. Type the command “set led off”. Press return.



23. The Aux board should respond with “HEY LED OFF”.

24. Type the command “set flame off”. Press return.

25. The Aux board should respond with “HEY FLAME OFF”.

The same tests can be run for other options on the board as shown in the DaVinci Command Protocol document. Other options include LEDFADETIME, HUMIDITY, TEMPERATURE, DEWPOINT, HEATFAN, etc. The commands stay the same.

GET asks the board what the setting is currently (i.e. “GET FLAME” and the board would respond “OK HEY FLAME OFF” if the flame is off.)

SET tells the board that you want to change a setting (i.e. “SET LEDCOLOR 0, 255, 0, 0” and the board would respond “OK HEY LEDCOLOR RED: O GREEN: 255 BLUE: 0 WHITE: 0”).

If the board responds to the commands as described above, it indicates that it is functioning properly. If there are still issues getting a smart home system to control the fireplace, you will need to troubleshoot the smart home system to find the communication issue.
