I have a Solectria PVI7600 and I am trying to access the RS485 port. My end goal is to hack one of the following projects into something I intend to open source after:
https://www.deuxpi.ca/pysunrise/
https://github.com/bchess/solectria_reader
I am using a Votek UT-2011 for my RS485/232 converter. I have it connected to a USB/Serial port on a Linux host (Ubuntu). The Linux host sees the USB/Serial port as "/dev/ttyUSB0". All the physical physical cabling seems correct. The SW revisions on my PVI7600 are:
AC 01.04.01
DC 01.04.01
SYS 02.01.01
ENS 02.01.01
I have been unable to get pysunrise to gather any data. I have modified the code to support my USB port and PVI RS485 ID setting of "1". If I open minicom and try to access the /dev/ttyUSB0 directly, I don't receive any response. At this point I need help trying to further troubleshoot this. Either I am not sending proper key sequences to have the PVI respond or I have a physical connection problem. I welcome any feedback or suggestions. Thanks!
