MISCELLANEOUS FEATURES 
 
SERIAL PROGRAM MODE  
 
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.
