Sol-Ark 12k Outdoor

On the 12k outdoor model the port labelled as CAN is both a CAN and RS485 port by containing the pins for both. This is the correct port to connect SolarAssistant to. The RS485 to the left of the CAN port will not work. If your CAN port is already used to read a battery via CAN, then you can use an RJ45 splitter to split the port into two. When it's split into two, you can use the CAN pins in one port and the RS485 pins in the other. Note the splitter should simply connect the pins of the ports, it should not be an ethernet switch.
