• Combination of a computer and multiple inverters (1:n)
RS-485
interface/
terminals
RS-232C
cable
*1 The inverters may be affected by reflection depending on the transmission speed or transmission distance. If this reflection hinders
communication, provide a terminating resistor. If the PU connector is used to make a connection, use a distributor since a terminating resistor
cannot be fitted. Connect the terminating resistor to only the inverter remotest from the computer. (Terminating resistor: 100 W)
NOTE
• Computer-inverter connection cable
Refer to the following for the connection cable (RS-232C to RS-485 converter) between the computer with an RS-232C
interface and an inverter. Commercially available products (as of February 2015)
Interface embedded cable
DAFXIH-CAB (D-SUB25P for personal computer)
DAFXIH-CABV (D-SUB9P for personal computer)

Connector conversion cable DINV-485CAB (for
inverter)
Interface embedded cable dedicated for inverter
DINV-CABV
*2 The conversion cable cannot connect multiple inverters. (The computer and inverter are connected in a 1:1 pair.) This product is an RS-
232C to RS-485 conversion cable that has a built-in converter. No additional cable or connector is required. For the product details, contact
the manufacturer.
• Refer to the following table when fabricating the cable on the user side.
