Interesting... The doc (http://www.lovatoelectric.com/HandlerDoc.ashx?s=I365GB12_12.pdf&ic=119) says it is a RS485 line. I guess that A+/A+ are connected and B-/B- too for easy chaining. But page 3-13 describes a plain serial connection too (pins 4/5 RXD0/TXD0). That is the test entry point (needs to be tested for 5V or RS232 levels). It may be the console or an alternative interface. You should be get some info from there. My best guess is that they have mapped the entire register space from the front-panel config (page 4-9 and forward), as documented, to the communications register map. That should be possible to test with a few read commands. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
