mpptracker shows nothing

I have an inverex mks 5kva and I tried connecting it to my laptop via ethernet cable and downloaded mpptracker in my laptop but nothing showed up on my screen. Do I have to do some settings? The communication cable came with the inverter had an rs232 port on one side and lan port on the other (picture of which is attached below) and I did not have rs232 port in my laptop so I had to use an ethernet cable to connect my inverter to the laptop

    Do you have a router that you can connect to your device?

    It has been a very long time since I tried connecting a laptop to some other device via 10/100 Base-T cabling directly...

    What operating system is the laptop? What brand and how old is the laptop?

    Thanks for the reply, bill. I have a router but I don't think it connects to the router. If it does, do I need to connect via the ethernet cable? because it does not have wifi or Bluetooth. there is just one ethernet port on the inverter so if I connect it to the router, I cannot connect it to the laptop.
    This is the inverter I own:



    and this is the wire that came with the inverter but because my laptop does not have an rs232 port, I had to switch to the ethernet cable:

    I find it odd that if it came with a RS232 cable it wasn't for the inverter.

    If you are connecting directly to your computer, you may need a network 'crossover cable' though I had understood these were no longer needed in the last 10 years or so... Then again one of the supplied cables is RS232...

    You can likely still find them, maybe still required. Alternatively post in a local computer group and someone will make you one for a couple bucks.

    Routers have multiple ports, so you'd connect both the inverter and your laptop to the router.  The router will give each device an IP address which allows them to communicate with each other.

    I am going to take a wild guess and say that is not an RS-232 to xBase-T Ethernet converter... But just a simple DSUB-9 to RJ45 connector (using RJ connectors for wiring instead of DSub connectors).

    If you where looking to converter from RS-232 to Eithernet, then you would want something like these (I think--too many years since I have worked with this stuff):
