REMARKS
⋅ 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. Commercially available product examples (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. Contact a maker for details of the product.
⋅ Refer to the following when fabricating the cable on the user side.
Commercially available product examples (as of April, 2004)
* Do not use pins No. 2, 8 of the 10- BASE-T cable.
CAUTION
When performing RS-485 communication with multiple inverters, use the RS-485 terminals. (Refer to page 312)
