Problem interfacing Symbol LS2208 with Arduino

Hi, everyone. I been looking for information in the forum and google with no sucess. The barcode scanner manual says that communication is TTL-RS232 because the vcc is 5v to feed the device, so i connected to arduino directly without max232 or max3232(of course i tried too, but nothing happen, only direct connection throw me data). The matter is that the data that i recieve i don’t know how interpret it, i’m read only code 39… Here is the code, it’s a super simple code:

#include <SoftwareSerial.h>

SoftwareSerial scanner(10,11);

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  scanner.begin(9600);

}

void loop() {
  if(scanner.available()){
    Serial.println(scanner.read());
  }
}

I connected the pins like this:
RS232 Arduino
2(RX)--------->10(RX)
3(TX)--------->11(TX)
5(GND)------->GND

When i scan a barcode “215774”, the monitor serial shows:
179
86
22
22
118
6

If i scan a barcode “170264”, the monitor serial shows:
103
100
182
54
118
6

How i have to do for get the same number that i scanned? or i ignored something?

I would appreciate so much your help, thank you!

How did you configure your scanner? What type of barcode do you scan?

BTW: you forgot the link to the devices manual: https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/barcode-scanners/ls2208-product-reference-guide-en-us.pdf
