EZ-KIT Lite Hardware Reference
ELVIS Select Jumper (JP2)
The ELVIS select jumper (JP2) configures the EZ-KIT Lite’s connection
to an ELVIS station (see “ELVIS Interface” on page 1-8). When
JP2 is
installed, the connections to the push buttons and LED are re-directed to
the ELVIS station, instead of the processor. The jumper settings are
shown in Table 2-11.
ELVIS Voltage Selection Jumper (JP3)
The ELVIS voltage selection jumper (JP3) 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
JP3 is installed,
the board is powered from an ELVIS station and no external power supply
is required. The jumper settings are shown in Table 2-12.
[
The external power supply must be disconnected from the board
when
JP3 is installed. In this case, the power supply may cause
damage to the EZ-KIT Lite board and ELVIS unit.
