Hello Buiphuquoi,

Inverter end is CAT5 connector (This connects to the programming console socket).
PC end is a standard 'D' type Serial connector.

Pin 7 at CAT5 connects to Pin 2 at D type Serial.
Pin 6 at CAT5 connects to Pin 3 at D type Serial.
Pin 2 at CAT5 connects to Pin 5 at D type Serial.

Having done this a few times myself, I suggest you get yourself an Ethernet cable, and cut one end off.
Then solder the 3 required cables to a 9 pin D connector as described above.

Hope this helps.
