Pins 1, 3 - RS232 They are used for UART BSL communication and need to be connected to the corresponding
RS232 inputs of the target board.
Attention: The RS232 pins are no TTL pins but real RS232 levels (MAX232 driven).
Pin 5 - LIN This is the LIN bus connection to the LIN transceiver implemented in the µIO- Stick, it is suited to
drive a corresponding LIN input of the target system.
Pin 7 - Target Reset This pin is intended to drive the reset input of the target device in order to synchronize the
device state with the attempts to establish a BSL connection. The connection of this pin to the reset of the target
device is not necessarily required, as synchronization can also be achieved by:
• power cycling of the target device by Pin 6 (VS)
• keeping the target device in BSL mode by configuring an appropriate NAC value
Pin 2 - GND This is the common ground connection to the target system.
Pin 6 - VS This pin can either be driven from the implemented charge-pump of the µIO-Stick (+12 V/200 mA) or
can be overridden by an external supply, i.e. the supply of the target device. This pin is also being used to
internally drive the LIN transceiver available on the µIO-Stick. If BSL communication over the LIN interface is
intended, then the supply of Pin 6 is mandatory.
