Pin Assignments for the PowerLink Cable Keyboard Wedge
Interface
The MS7120 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.
