How to connect VFD to a laptop or computer?

[dream-builder]

I was recently trying to connect my Delta VFD drive with my laptop using Vfd-Soft software (which I downloaded from Delta website) and RJ 45 to USB converter(RS232/RS485 converter). I connected the variable frequency drive to supply and connected the connecting lead to drive and pc both. I then ran the VFD-Soft software for interface. Using the Com port which was assigned to usb I used automatic detect settings for Baud rate and protocol. Then clicked the TEST button and a Success Green Signal was displayed. Next I went to step 3 to accept the settings and go online, but a error message was displayed that communication time out.
I don't know what is this and how I can resolve this issue.
Kindly help me to solve the issue.

Is your software registered? Is your module registered? Getting success until the crucial moment, then a strange error message appearing might be their way of blocking unregistered software or hardware.

Hi,

I do know neither this VFD nor the software, thus at first I'd read the manuals.
