Bar Code Scanner

I am trying to connect a bar code scanner to my PICO.

Serial2.setup(9600, {rx:A3,tx:A2,bytesize:8,parity:none,stopbits:1,flow:none});
Serial2.on('data', function(data) {
  console.log(data);
});

The response I am getting is gibberish though?

I have tried various other baud rates and nothing seems to work. The code should read 0000027840200.
Any ideas??
