HOW TO DISABLE OPERATING MODES
The operating modes of the KEEMUX can be disabled if a user desires to do so. The Command Mode can be disabled
which would also disable the Scan and Broadcast Modes, or, the Scan and/or Broadcast Modes can be individually disabled
leaving the other features in Command Mode enabled.
To disable these operating modes, the user must get access to the jumper block. This block is located close to the dip-
switches on the circuit board the keyboards plug into (called the digital board) inside the KEEMUX. (See Fig. 17.)
Figure 17- Location of the jumper 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 10 screws from the cover to get access. With the cover removed, the jumper block will be easy to locate. Follow the
instructions under "CONFIGURING THE JUMPER BLOCK" on page 24 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 jumper block.
For models KEEMUX-Px in a plastic case:
1. Make sure the KEEMUX is completely disconnected from all CPU components. Be sure to unplug the KEEMUX from
the electrical outlet.
2. Remove the two Philips-head screws from the underside of the KEEMUX and set the KEEMUX on a firm and flat
surface, bottom down. (See Fig. 18.)
