PROGRAMMING INTERFACE OVERVIEW

The table below shows which interfaces can be used to program the flash memory of the various Z-Wave 700 products:

CALIBRATION

It is mandatory to calibrate the crystal in EFR32ZG14 Z-Wave 700 devices during product development to make sure that the mean
value of the crystal frequency is correct. Refer to [4] for calibration instructions. Furthermore, for best possible performance, it is
recommended that calibration be performed during production to minimize the spread in crystal frequency. All ZGM130S Z-Wave
700 devices are calibrated during production and therefore do not need any further crystal calibration.
4.1

CRYSTAL

It is recommended to calibrate the crystal frequency for the gateway devices to ensure minimum error of the radio carrier
frequency.

RF VERIFICATION TOOL

The RailTest tool can be used to verify the RF performance of a device without the overhead of the Z-Wave protocol. The same RF
PHY present in the Z-Wave protocol is used. The tool is suitable when investigating RF performance and performing RF regulatory
tests. To use the tool, it is required that the chip is programmable and the UART0 is connected to a terminal over RS-232 or
through the WSTK. For a comprehensive user's manual for the RailTest tool, refer to [2] and [3].
As the RF PHY can be updated for new software releases, it is important to compile a RailTest version based on the same software
release that will be used in the final product.

SAW FILTER

It is recommended that a SAW filter is used in Z-Wave 700 gateway designs also containing GSM or LTE transceivers operating in
the subGHz band. A SAW filter attenuates unwanted radio emissions and improves the receiver blocking performance. Three
