It is essential to follow the proper hardware installation procedure to ensure that your Z-Wave Programmer software works correct. 
Use PDF version of the Z-Wave Programmer User Guide (INS10679) to get a printed copy of this procedure.
1.	Install CP210x USB to UART Bridge Virtual COM Port (VCP) driver.
Note! This should be done before the Z-Wave Programmer hardware (ZDP02A Z-Wave Development Platform) is connected to the USB interface.
To run the CP210x VCP driver installation wizard, open C:\DevKit_X_YY\Tools\Programmer\CP210x_VCP_Win2K_XP.exe executable file and follow the installation wizard.
2.	Check the jumper settings on Z-Wave Programmer hardware (ZDP02A Z-Wave Development Platform).
Jumpers J10, J11 and J13 should be short.
Jumper J9 should be open in case the Z-Wave module connected via the ISP cable and uses an independent power-supply. Otherwise it must be short.
3.	Mount Z-Wave module either directly in Z-Wave module connector or connect units using the ISP cable.
Z-Wave module can be mounted directly on Z-Wave Programmer hardware (ZDP02A Z-Wave Development Platform) using the Z-Wave module connector. This configuration allows writing data to the external EEPROM on the Z-Wave module and debugging the embedded application.
Alternatively Z-Wave module can be mounted on Z-Wave interface unit and then connected to the Z-Wave Programmer hardware via the ISP cable. The Z-Wave module can be powered via the Z-Wave Programmer hardware. In this configuration it is impossible to write data to the external EEPROM on the Z-Wave module.
4.	Plug the power supply.
The Z-Wave Programmer hardware cannot be powered via the USB interface so plug the external power supply to it.
5.	Connect Z-Wave Programmer hardware (ZDP02A Z-Wave Development Platform) to the PC using the USB cable.
Windows will detect the new hardware and the new hardware wizard will start.
Select No, not this time on the wizard then click Next.
On the next page select Install from a list or specific location option.
On the next Wizard page point to the location of the USB driver you installed previously at step 1, it is “C:\SiLabs\MCU\CP210x\Windows_2K_XP_S2K3_Vista” folder by default.
6.	Install driver for the new hardware.
Follow the wizard to install CP210x USB to UART Bridge Virtual COM Port (VCP) driver as described above.
Note! This step is required to complete twice to avoid being prompted every time you connect the Z-Wave Programmer hardware.
7.	Restart the PC when the USB driver installation is finished.
Make sure you completed this procedure to install the Z-Wave Programmer hardware. Click Next to continue. 
Otherwise click Cancel and re-start the Z-Wave Programmer installation after Z-Wave Programmer hardware is ready to use.
