Application note
Transparent serial link over ST7590 OFDM PRIME modem
1
Introduction
Nowadays, a lot of power meter manufacturers or smart grid providers are switching from
simple networks like RS845 to more sophisticated ones like PRIME. In order to help and
inform CTMs in their evaluation phase with transition from a simple protocol to a more
sophisticated one, a transparent bridge between RS485 and PRIME would be welcomed.
Such a system could easily help to evaluate PRIME protocol in the lab and in the field.
STMicroelectronics™, as a chip manufacturer, provides a system-on-chip realizing PRIME
protocol ST7590, and the implementation of such a transparent bridge is described in this
document. A part of this application note is a zip archive file with a firmware referenced
within this document.
