Set the scanner to "Beep on BEL Character" by sending the command BELBEP1. After this command, when the scanner receives a BEL character (hex 07), it will beep.

  • thanks sir , can you help me how to send command to my scanner in c# ? – Hossein Bagheri Aug 28 '17 at 07:49
  • Unofrtunately not, but make sure to read the "Serial Programming Commands" section in the technical reference guide, since you must follow a specific protocol when sending commands. You can not just send the string "BELBEP1". – Marc Balmer Aug 28 '17 at 07:51

    that was exactly right --> byte[] bytestosend = { 0x07 }; serialPort1.Write(bytestosend, 0, bytestosend.Length); – Hossein Bagheri Aug 29 '17 at 04:51
