What type of cable should I use?

Can you Please tell me which cable should I use to connect my portserver 8 RJ45 to the hub? I am using with window XP, and config as a RealPort.

When I use a regular cat 5 RJ45, It tell me there were no port

Hub as in Ethernet hub? If so, use the same kind of cable you’d plug a PC in with. We’re a standard Ethernet client.

I got error message “error opening port or port invalid”

Please help. I tried to config the portserver rj45 to be realport, connecting through an ethernet hub.
