Signal Direction is described from the BlueBox perspective.

 

Warning_orange

When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure.

 

Additional cable

If the 26-pin 1.27mm pitch ribbon cable gets damaged, it can be ordered as a spare part under the ordering codes:

IA26PIN26PIN127

IA26PIN26PIN127-CUST -  Custom cable length must be specified at the order.

IA20PIN20PIN127

Warning_orange

Note that the optional length should be reasonable (e.g. 10 cm) since the quality of electrical signals degrades with prolonging the cable.

 

i-icon

BlueBox functionality with this cable, intended for rare situations when the standard debug adapter cannot connect to the target due to physical obstacles, is not guaranteed. Using the BlueBox at lower debug frequency scan speeds without trace functionality may be an acceptable compromise. You should test the BlueBox with a custom-length ribbon cable to ensure compatibility with winIDEA.

Make sure this adapter fits on your Target connector.
