This pin is not connected in Flasher ATE.
19 5V-Target
supply
Output This pin is used to supply power to some eval boards. Typi-
cally left open on target hardware.
Pins 4, 6, 8, 10, 12, 14, 16, 18, 20 are GND pins connected to GND in Flasher ATE. They
should also be connected to GND in the target system.
9.1.3 Target power supply
Pin 19 of the connector can be used to supply power to the target hardware. Supply volt-
age is 5V, max. current is 400mA. The output current is monitored and protected against
overload and short-circuit.
Power can be controlled via the
ASCII command interface
on page 59 or by enabing power
supply in the project configuration.
