beeping three times. The low intensity 
blue LED will remain turned on. 
Installation Note 
Plugging the imager into a port on the host system does not guarantee that 
scanned information will be communicated properly to the host system.  
The imager is shipped from the factory configured with default settings.   
Please refer to the MetroSelect Single-Line Configuration Guide (PN 00-02544) 
or MetroSet2’s help files for instructions on changing the imager’s configuration.  
In addition, please check that the imager and host system are using the same 
communication protocol.  
  The MS7580 requires 12V power from the host for RS485 operation.
