Negative Positive
Title: old firmware or new?
Review: Apparently, you can't update the firmware on this unit. The update feature in the software directs you to a link to the website for the update ".bin" file, but no such file exists. I've looked for hours to no avail. Also, serial ports are obsolete - this scanner should have a USB interface for connecting to your PC. I had to purchase a separate usb-serial adapter, which is an extra needless step...
