I have decoded both signals and they are essentially the same, just the scanned data followed by CR and LF (Carriage return and Line Feed).Ī normal USB to serial adapter does not work as the new software can't accept data from comm port like the old software. Both of these are one-way data only from the scanner to the computer. Their old system uses an RS-232 serial link that spits out the code at 1200 baud to a comm port that was monitored by the old software. Their new software uses barcode readers that emulate a USB keyboard and just dump text into a field in the software. Our local library has updated their software, but want's to keep using their old scanning kiosks. I need to build a cable adapter that will take an RS-232 serial input and convert it to an HID keyboard output.
