Have you "connected" to the controller using the serial cable?
My guess is you have NOT
You need to read from the controller it's exact network configuration
Download MSView - Open MSView - Open the Tristar MPPT setup Wizard - Create a new configuration - Make it a Solar Charge controller - Proceed to the Network Communications configuration page (5 or 6 pages into the configuration SETUP) .......This will be the standard default setting but might not be how yours is configured for - YOU will need to connect to the controller - Strongly suggest you do that with a Serial data cable a null Modum 9 pin D type cable - you will need a USB to serial adapter and setup the proper Baud, data bits, and stop bits for RS232 communications - The setup is clearly detailed in the manual
