    likely ethernet/IP, but I do know that USB is used as well. Going a while back, R232 was common.

    My new laptop doens't carry a RS232 port. So i have to use USB to RS232 converter. How many types of converters is there? Or is it only one type?

    No there are many. You have to be sure the one you get will report to the proper pins on the rs-232 side. Some are not 'straight thru' devices. The computer must be using a proper driver for the device also.

    I have found 1 that is..:

    another thing to watch out for is required use of handshaking for rs-232 devices

    a lot of usb-serial converters do NOT allow for manipulation of these pins and can leave you frustrated wondering why things arent working.

    your best bet is to try the suggested converter out - and if things arent working you may need to invest in a serial comms card for your PC.
