HOW TO DISABLE OPERATING MODES
Two operating modes of the USB
Wizard can be disabled if desired. The Command Mode can be disabled which
would also disable the Scan Mode, or, the Scan Mode can be separately disabled leaving Command Mode
enabled.
To disable these operating modes, the user must get access to the jumpers block. This block is located close to the dip
switches on the circuit board the keyboards plug into (called the digital board) inside the
USB Wizard.
(See Fig. 2
0)
Figure 20- Location of the jumpers block
If the unit is a rackmount style, the digital board is located directly beneath the cover of the unit, requiring the user to only remove
the 9 screws from the cover to get access. With the cover removed, the jumpers block will be easy to locate (see Fig. 2
0).
Follow the instructions under "CONFIGURING THE JUMPER BLOCK" (page 2
1) to disable the desired mode(s).
If the unit is in a plastic case, the digital board is located on the bottom of the case, requiring the user to partially disassemble the
unit to gain access to the jumpers block.
For models in a plastic case::
1. The
USB Wizard must be completely disconnected from all computer components.
2. Unplug the
USB Wizard from the electrical outlet.
3. Remove the two philips-head screws from the underside of the
USB Wizard and set the USB Wizard on a firm and flat
surface, bottom down (see Fig. 2
1).

4. Remove the top half of the plastic case from the
USB Wizard.
Note: Before proceeding, it is important to discharge any static charge by touching any large metal object (away from
the USB Wizard).
