I/O Standard Description
Power
GND
O
—
Digital ground from the RMC
connector host system.

O
—
3.3 V_AUX from the RMC
connector host system. The
rail is always on when the
main host system is connected
to power.
5 V
O
—
5 V from the RMC connector
host system.
FPGA_VIO
O
—
I/O voltage for the FPGA
3.3V
pins.
VIN_FILTERED
I
—
9 V to 30 V input to power the
device through the RMC
connector rather than through
the front panel connector.
VBAT
I
—
This pin may be used to
connect a longer life battery to
