1.  Turn off power to the host device. 
2.  Plug the interface cable’s modular  
connector into the socket on the imager.  
3.  Disconnect the keyboard from the 
host device. 
4.  Connect the “Y” ends of the 
communication cable to the keyboard 
and the keyboard port on the host 
device. A male/female adapter cable is 
supplied with the imager kit. 
5.  Plug the 12V power supply
 into the 
power jack on the cable. 
6.  Check the AC input requirements of the 
power supply to verify the voltage 
matches the AC outlet.  The outlet must 
be located near the equipment and be 
easily accessible. 
7.  Connect AC power to the transformer. 
8.  The MS7580 will start to initialize.  The 
white and blue LED will alternately fade 
on and off for three seconds.  When the 
imager has finished initializing, the 
imager will flash the white LED three 
times while simultaneously beeping 
three times.  The low intensity blue LED 
will remain turned on. 
9.  Turn on power to the host device. 
 
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 to function for Keyboard Wedge operation.
