Signal
Description
DIO
Digital input/output signal connection
EXTCLKIN External clock input source that can be used for source synchronous
acquisitions. The provided clock source must be stable and glitch-free.
GND
Ground connection
The PCIe-7821R is protected from overvoltage and overcurrent conditions.
