The on-board jumper options allow configuration of on-board power supplies and ADC options. Many of
the jumper selections that involve DC inputs or static control signals are by way of push-on square post
jumpers. The jumper options are listed in Table 3. The table indicates the default settings of the jumpers
as the EVM is normally shipped. Some of the jumpers are open circuit by default.

ADC trigger input. This can be used to start the rev. E to the ADC trigger input
auto-burst process.
There are two pushbuttons on the EVM. While JP7 is set in the 2-3 position, the pushbutton switch, SW1,
provides a hardware reset to the ADS58H4x. Upon powering up, the ADC can either accept a hardware
reset by pressing SW1 or by toggling the software reset switch on the EVM GUI. Table 4 lists the
descriptions of each pushbutton switch.
If the ADS58H4x is configured for high resolution burst mode, pressing SW2 while JP12 is set to the 2-3
position allows the ADC to enter burst mode. The SW2 pushbutton also provides the initial pulse needed
to start the auto-burst mode process after the ADC is configured in High Resolution Auto-Burst mode.

SW1 While JP7 is set in the 2-3 position, pressing SW1 resets the ADC. The ADC can be reset either by pressing
SW1 or with a software reset in the GUI.
SW2 While JP12 is set in the 2-3 position, pressing SW2 allows the ADC to enter burst mode. This can also
provide the initial pulse needed start the auto-burst process.
