ADDRESS : SYS
MEDIA : USB
-->Please can you tell me if I did the good selection.

Also this CPU have one port of Communication
- I can not connect to the CPU through the RJ45 port with the Ethernet cable " type straight"
in SET ADDRESS Menu I choice :
ADDRESS : I convert the MAC address HEXADECIMAL TO DECIMAL : 00.80.F4.07.A1.34. I convert to Decimal 84.07.161.52
