2. determine if your application requires usb keyboard communication protocols or usb point-of-sale communication protocols.
3. if you require usb keyboard communication protocols, skip to step 4.
if you require usb point-of-sale communication protocols set the dip switches shown in figure 4a to positions 1 and 2.
4. connect the powerlink cable to the 10-pin usb interface jack. it is the 2↑nd round opening from the left side of the ms7320 (see figure 4b).
5. connect the other end of the usb cable to the host.
before continuing verify that the usb cable is connected to the appropriate interface jack on the scanner. an incorrect cable connection can cause communication problems or potential damage to the scanner.
plugging the scanner into the usb port of the pc does not guarantee that scanned information will appear at the pc. a software driver and correct configuration setting are also required for proper communication.
6. scan the enable usb defaults bar code to configure the ms7320 for usb communication.
7. turn on the host system.
8. snap on the cable cover.

1、to maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for selv (safety extra low voltage) according to en 60950.
2、to maintain compliance with standard csa c22.2 no. 60950-00/ul 60950 and norm en 60950, the power source should meet applicable performance requirements for a limited power source.
