2. Connect the debug adapter to the other end of the 25 cm 40-pin ribbon cable.
Align the notch on the 40-pin debug adapter with the orientation key of the connector of the
40-pin ribbon cable. Press the cable carefully straight down until the latches lock.
3. Ensuring that the BlueBox and the Target are not powered, and that the Grounding wire
is securely connected, connect the debug adapter to the Target.
Do not use any excessive force when pressing the connector onto the target system’s
connector. The connector requires minimal force if it is correctly aligned.
Observe the orientation key (either on the connector itself or implemented through a
missing “key” pin) or the position of pin 1 as indicated by the ribbon cable’s red marker
wire!
To disconnect the ribbon cable, squeeze the two metal latches on the cable connector inwards
and pull the connector gently from the socket.
If the delivered ribbon cable does not meet your needs, iSYSTEM offers a range of alternative
lengths. Please refer to the Accessories chapter for available ribbon cables.
The quality of electrical signals degrades with prolonging the cable. iSYSTEM gives no
assurance for BlueBox operation with such cable. The cable is meant to be used only for
boundary cases where BlueBox cannot be connected to the target hardware through the
standard 25 cm long ribbon cable, for example due to the physical obstacles of the
target system. In such cases, operating the BlueBox at lower JTAG scan speeds and not
using the trace functionality at all, might be still an acceptable compromise. It’s up to
you to thoroughly test and qualify the BlueBox operation using longer ribbon cable and
to determine working winIDEA settings for the system.
