I need access to my digi portserver II 16 to configure

Hello guys, I just got a portserver ii unit and cannot get it to work. Driver is installed and unit is powered up however, I have not been able to see the serial com ports mapped in my computer. I need access to the portserver ii 16

I don’t have access the units IP address, not sure if it is the cables am using ie; CAT5, CAT6

I have confirmed the unit is obsolete but advised to seek for help in the forum

This forum may help to address the issue, you may have to use a crossover cable.
