How to send data from serial port to NodeRED?

image
Im connecting my wireless USB barcode scanner with my raspberry Pi Zero W. Im able to receive the data using pi zero but not for Node-RED. There is no message being show up. Can anyone help in this matter?

Looking at the second screenshot your barcode reader emulates a keyboard.
So you must look for node that can capture HID devices or maybe you can reconfigure your scanner to output serial data

Ok. I will try to use it later on. So, the normal serial in node is not really suitable for this case?

I am not able to install the palette

Im able to install the palette after changing my Node.js version to v8.12.0. Now i can proceeds to convert the data obtain from my scanner. Thanks alot.:slight_smile:
