For Serial Program Mode, all commands must be framed by an STX (02 Hex) and ETX (03 Hex).
To recall defaults:
1) Transmit <STX>999999<ETX> through the Serial Port. This will put the scanner in serial
program mode. Scanning will be suspended and the scanner will respond with an ACK (06 Hex).
2) Transmit <STX>999998<ETX> through the Serial Port. This is the Recall Defaults bar code in the
MetroSelect guide. The scanner will respond with an ACK (06 Hex).
3) Transmit <STX>999999<ETX> through the Serial Port. This will cause the scanner to exit
program mode and save the new settings. The scanner will beep 3 times and send an
ACK (06 Hex).
If at anytime, the scanner cannot recognize a command, it will respond with a NAK (15 Hex).
Please refer to the Installation and User’s Guide of the scanner for a complete description of Serial
Program Mode.
