Frequently Asked Questions
Have a Question?
-
What is the maximum cable length I can use with this adapter?
Standard TC2050-IDC cables are 8 inches long. For longer distances, consider the signal integrity requirements of your specific debugging protocol and target clock frequencies.
-
Does the adapter provide target power to connected devices?
The adapter passes through the debugger's power pins (typically pin 19 at +5V or +3.3V), but actual power delivery depends on your specific debugger's capabilities and configuration.
-
How does this compare to using two separate single adapters?
The TC2050-2x10 provides a more compact solution than dual adapters, reducing cable clutter and bench space whilst maintaining identical functionality and signal integrity.
-
Is the adapter suitable for production programming?
Absolutely. The robust PCB design and reliable connections make it ideal for production environments requiring dual target programming or testing workflows.
-
What cables do I need to purchase separately?
The adapter requires two TC2050-IDC or TC2050-IDC-NL cables for complete operation. These connect between the adapter headers and your target PCBs' Tag Connect footprints.
-
Can I debug two different microcontroller families simultaneously?
Yes, each 10-pin output operates independently, allowing debugging of different ARM cores, microcontroller families, or even mixed ARM/non-ARM systems simultaneously.
-
What is the pin mapping between the 20-pin input and dual 10-pin outputs?
The 20-pin connector maps pins 1-10 to header J1 (rightmost) and pins 11-20 to header J2 (leftmost), maintaining standard ARM JTAG pinout assignments.
-
Does the adapter support both JTAG and SWD protocols?
The TC2050-2x10 maintains full compatibility with both JTAG (4-wire) and SWD (2-wire) debugging protocols, automatically adapting based on your debugger and target configuration.
-
Can I use both legged and no-legs cables with this adapter?
Yes, the adapter supports both TC2050-IDC (legged) and TC2050-IDC-NL (no-legs) cables. For no-legs variants, you may need TC2050-CLIP retaining clips for hands-free debugging.
-
What debuggers are compatible with the TC2050-2x10 adapter?
The adapter works with all standard 20-pin ARM JTAG/SWD debuggers including SEGGER J-Link, ST-Link/V2, ST-Link/V3, XJTAG systems, P&E Multilink, and Lauterbach TRACE32 units.
