Problem reading RS232 7E1 from digital scale

[agungadi]

I am trying to read data in arduino uno from digital monitor scale GSC SGW 3015 PS. I use MAX232 to connect serial with the monitor scale.
The scale monitor provide rs232 passive 7E1.

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600,SERIAL_7E1);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // set the data rate for the SoftwareSerial port
  mySerial.begin(2400);
}

void loop() { // run over and over
  if (mySerial.available()) {
    Serial.write(mySerial.read());
  }

  delay(100);
}

The code above throw unknown charcters

Anyone know, how to read the data correctly ??

You need to set up myserial for 7E1, not Serial.

As I understand the balance is read by myserial. The balance uses 2400 baud and 7E1.

To where, what does the Serial.write go?
