Lightwave Communications USB-Wizard HOW to Disable Operating Modes, For models in a plastic case

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. 20)

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. 20). Follow the instructions under "CONFIGURING THE JUMPER BLOCK" (page 21) 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. 21).
