When I connect it to the serial port on my desktop, it is working fine. The problem is, I have to do the programming part in my laptop. My laptop does not have any serial ports, so I purchased a connector that will convert it to usb. I tested the connector in the desktop, all ps/2 devices (ex. mouse) works fine. But when it comes to the barcode scanner, the computer cannot read the device. Which is weird. It can read the device when I connect it to the serial port, but it does not read the device when I connect it to the USB via a connector or converter. Any ideas?
some devices just do not work via the USB converters.
I have seen paralel printers for Point of Sale apps not work via USB/Paralel adpaters for example.
the Serial barcode reader/scanner may require a "real" serial port.
does this have a driver in the OS when you set it up?
or is it just a raw Serial like an old Modem ?
can you get a USB scanner from the same Mfg ??
new PC's are not having serial ports so I would work on moving to USB .... in the end I think it's worth it.
9pin and 25pin Serial is just about gone.
and really USB is a 4 wire serial buss anyway...
