FA-T-RS40 type*
* 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.
