Unfortunately there is no way to tell identify the port just by model name as different GPS tracker manufacturers use same name for completely different devices. Please read following page:

I ended up purchasing the TK103A to configure with Traccar. I am almost complete, but seem to be having difficulty getting it to communicate with the traccar server. Can I get confirmation on the port number that it will work on?
Thanks,
