6 Dust Networks ETERNA2 Regulatory User Guide
2.2 API UART
ETERNA2 offers a comprehensive Application Programming Interface, API, that provides full programmatic access to
control the device, monitor its status (such as battery charge and network status), and provide access to the wireless mesh
network. Messages over the API UART are HDLC encoded and require specific software to support command and response
communication required for regulatory testing. Refer to the SmartMesh API Guide for details.
3 Test Configurations
Test configurations can be divided into two distinct configurations, one for Radiated immunity and a second for Emissions
and Conducted Measurements.
3.1 Radiated Immunity
Operation of the network in the presence of an interferer can most easily be monitored by operating ETERNA2 as a mote
participating in a network. In this configuration, the RF link between the ETERNA2 and a network manager can be
exercised and simultaneously monitored via the network managers UART CLI port. Communication and monitoring to the
UART CLI port can be done via generally available terminal emulation software, such as TeraTerm, HyperTerminal, or
iTerm2.
3.2 Emissions and Conducted Measurements
Emissions and Conducted measurements can be made with ETERNA2 integrated into a product or stand alone. When
integrated into a product a convenient method to invoke commands over ETERNA2’s CLI or API UART should be
considered as part of the product design. To access the CLI port and power on ETERNA2 in a stand alone configuration, a
Samtec MTMM-111-04-S-S-175-003, connector should be installed on J2, as shown below,
J2 per the pinout shown below, provides both power and connection to ETERNA2’s CLI port. Connection to pins 1 through
6 are optional for CLI access.
