評(píng)估板EVALKITST8500-1
The EVALKITST8500-1 is a platform which allows an easy way to evaluate the features andperformance of a power line communication (PLC) node based on the ST8500 modemsystem-on-chip and the STLD1 line driver.
This user manual explains the EVALKITST8500-1 hardware and software installation, and
details the evaluation of the kits.
This user manual does not explain the functionalities of the various PLC protocols running
on the ST8500. Detailed information can be found in the protocol specific documentation,
available within the software packages, separately delivered under the Software license
agreement by contacting your local ST sales office.
Based on the ST8500 power line communication System on Chip, the EVALKITST8500-1 evaluation kit embeds all the functions required for a turnkey power line communication network.
Depending on the PLC protocol targeted, different firmware releases should be loaded on the host Flash memory. Please check software release availability with your local STMicroelectronics sales office.
Intuitive graphical user interface (GUI) for the Windows? environment allows the user to upgrade the firmware release, configure and control the evaluation kit.
