Pin Assignments for the PowerLink Cable Keyboard Wedge
Interface 
The MS7100 Keyboard Wedge scanner interface terminates to a 10-pin
modular jack. Connect the 10-pin modular plug of the PowerLink cable 
into the jack then connect the other end of the PowerLink Y-type cable to the
host and keyboard (refer to page 7 for details). Due to the variations 
in current supplied by the many  available PC’s, Metrologic suggests the 
use of an external power supply.
