Modbus / Modbus TcpIP Cable Hitachi WJ200

« on: March 08, 2015, 03:04:13 PM »

I have a new Hitachi WJ200 VFD installed on a mill.  It works fine manually.  Now I am ready to connect it to Mach 3 with Modbus TCPIP.  Can I just use a USB cable from my computer to the USB port on the inverter?  If so, specifically  what type of cable do I need?  The end on the inverter is not a type I recognize.  I see mention on several threads about a RS232 to 485 converter....  Not thinking I need that with this inverter?  If not the USB then how do I need to physically connect the inverter to the computer?
