Pin Assignments for the PowerLink Cable
The MS7120 scanner interfaces terminate 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 cable to the host. (Refer to
page 6 for details). Due to the variations in current supplied by the many
available PC’s, Metrologic suggests the use of an external power supply.
