FIGURE 2-9:
HV MUX Controller Board GUI Screen Capture.
1.
Initialize HV MUX Controller:
when clicked, the GUI starts the initialization of
FPGA on the HV MUX Controller and the communication between the GUI and
the HV MUX Controller. If there is no error, the user will see “Initialization Com-
plete” in the message window.
2. STBY: when unselected, the STBY logic input is set to high and HV2903 is set
to operate in normal mode. When selected, the STBY logic input is set to low and
HV2903 is set to operate in standby mode to decrease power consumption.
3. MODE: when selected, the MODE logic input is set to high and HV2903 is set to
operate in individual switching mode. When unselected, the MODE logic input is
set to low and HV2903 is set to operate in bank switching mode.
4. DIN: 32-bit data entry boxes. Each bit in the boxes is related to each analog
switch. If data entry is 1, the associated switch is set to ON. If data entry is 0, the
associated switch is set to OFF.
5. CLR: when selected, the CLR logic input is set to high and all the switches of
HV2903 are set to OFF. When unselected, the CLR logic input is set to low and
the 32 switches of HV2903 are set to ON/OFF states, according to the DIN data
entry.
6. EN: when selected, the EN logic input is set to high and HV2903 is set to active
for bank switching mode. When unselected, the EN logic input is set to low and
