Operational Test
Metrologic recommends using the external power supply provided with the
scanner when operating the MS7120. When using power supplied by the host,
the host system should supply a minimum of 250 mA of current @ 5VDC.
Keyboard Wedge Scanners:
1. Connect the 10-pin modular plug of the PowerLink cable into the
scanner jack. Connect the other end of the PowerLink Y-type cable
to the PC. Connect the 5-pin female DIN side of the Y-type cable
into the keyboard connector on the PC and connect the 6-pin male
mini-DIN side into the PC.
2. Check the AC input requirements of the power supply to make sure the
voltage matches the AC outlet. Connect AC power to the transformer.
