ELVIS Voltage Selection Jumper (JP6)
The ELVIS voltage selection jumper (JP6) is used to select the power source for the EZ-KIT Lite. In a standard mode of operation, the board receives its power from an external power supply. When JP6 is installed, the board is powered from an ELVIS station, and no external power sup- ply is required. The jumper setting is shown in Table 2-12.

The external power supply must be disconnected from the board when JP6 is installed. Otherwise, the power supply can cause dam- age to the EZ-KIT Lite board and ELVIS unit.
ELVIS Select Jumper (JP8)
The ELVIS select jumper (JP8) configures the EZ-KIT Lite’s connection to an ELVIS station (see “ELVIS Interface” on page 1-12). When JP8 is installed, the connections to the push buttons and LED are re-directed to the ELVIS station, instead of the processor. The jumper setting is shown in Table 2-13.
