Cable for E700 from UB4.0 to COM

[temistocle]

I've buyed a cable for E700, but I've made a mistake: I' was searching for a COM cable, but this cable is for use with the Universal Box 4.0 :sad: It has 4 contact in a RJ-45 (2Yellow, 4Red, 5Green, 8Black). So, can I connect it to a Com port (RS232)?? Do you know the cable-schema? There is a way (via software) to use it trought the lan port? :-?
Thank you all
