Connectors

All low-level interface lines are isolated from system GND (and

are referenced to GNDI), except for the PWR line, which is

referenced to GND.

Ground Domains

The following diagram illustrates the two ground domains of the

programmer.

ATE and Target Ground Domains

In order to avoid undesired current paths between the

programmer and the target board, we suggest to use a power

supply with a ﬂoating output (ground not referenced to the

Earth potential).
