the interface-related settings and it will pass the new settings to 3666, which will then 
initialize and pass the settings to any other connected scanners.

3666. 
2)  Within one minute, connect the interface cable between 3666 and your computer. 
3)  The scanners will connect to your computer via 3666.

settings –  
  “Activate Keyboard Wedge & Select Keyboard Type” 
  “Activate RS-232” 
6)  Have the scanner read the “Update” barcode to exit the configuration mode. 
7)  After the scanner resumes connection with 3666, it will pass the interface-related 
settings to 3666.
