FlashRunner Quattro User's Manual
3.3 Control Connector
The “CONTROL” D-Sub connector is used to communicate with the host
system and for integration with automatic programming/testing equipment.
i
Note:
all control signals are referenced to GND_I, separate
from GND.
This allows a host system to safely communicate with
FlashRunner Quattro even when the target board has a
different ground reference than the host system’s (and it’s
not possible to connect them together).
Additionally, in order to avoid undesired current loops
between the FlashRunner power supply and the target
board, a power supply with a floating output (ground not
referenced to the earth potential) should be used.
