(1) Connection of a computer to the inverter (1:1 connection)

Computer-inverter connection cable
Refer to the following for the cable (RS-232C

RS-485 converter) for connection of

the computer having the RS-232C interface with the inverter.
Example of product available on the market (as of April, 2004)

*The converter cable cannot connect two or more inverters (the computer and

inverter are connected on a 1:1 basis). Since the product is packed with the RS-
232C cable and RS-485 cable (10BASE-T + RJ-45 connector), the cable and
connector need not be prepared separately.
