Read text content off RS232 port through a PC's USB port
« on: October 14, 2011, 12:05:13 am »
I’ve a PC which needs to read text content off a RS232 port of an industrial device connected to a printer.
I’m wondering a solution wherein I can connect a converter to read off the data and show it on the PC which only has USB host port support only?
Essentially it’s a RS232 to USB conversion, so that I can read off the text content available at the RS232 port off a virtual com usb port on the PC side to collect the text stream and show it on the PC.
Is there a converter that can do RS232 to USB, so that I can connect RS232 cable from industrial device to this converter and USB cable from this converter to USB port of a PC?

Yes, USB to serial converters are among the oldest USB products that are around.

Sorry, does this mean that I can get a USB to Serial cable which by your reply indicates can work bidirectional. Hence data can be read both ways in both ports without any issues?
