PortServer 2

Please Help with PortServer2 !!!1
Is the first time that I`am using PortServer2

How can I connect portserver 2 with cisco router? witch cable can I use? I just configure the PortServer like this:
#> set config ip=192.168.23.12 submask=255.255.255.0
#> set port range=16 dev=prn auto=off
#> set flow range=16
I can telnet the PortServer thru Ethernet port from other computer on my network.
Now I need to know which cable and how can I connect cisco router to the portserver2:

You can find the cabling details here:

Note: The cable ends are not interchangeable. The “Cisco” end needs to plug into the Cisco port.
