6.4 RS-485 connection
The SOLYS is equipped with a 4 wire RS-485 connection with galvanic isolation to the internal electronics and power supply. All
RS-485 wires have an over-voltage protection of 150 V to ground (chassis, VDC ground and VAC protective ground). The RS-485 is
ESD and surge protected (IEC 61000-4-2 / 4-5). The serial protocol, commands and messages are described in appendix A to E.
Both the RS-485 and the sun sensor have a 8 pin connector. Identification of the port is on the labels next to the connectors.
Exchanging the connectors will not work, but will also not cause any permanent damage.
