The XJLink is a legacy device that is not recommended for new projects. XJTAG recommends the XJLink2 JTAG controller.
- Small, lightweight, portable design: ideal for lab and field work
- Self-contained licence so you can use the XJTAG system on multiple PCs
- Re-configurable unit for multiple UUTs saving costs

Your test system where you want it
The XJLink contains the license for your XJTAG system. This allows you to easily move your licenses around on and off site to give you maximum flexibility. This also means you aren’t tied to one machine to do your XJTAG testing.
Configurable JTAG interface
Only a simple cable assembly is required to connect to your target board — no extra adapters needed. The 20-way connector on the XJLink is configurable from your test system.
The ability to change the pinmap for the JTAG signals simplifies the process of connecting your XJTAG test system to the Unit Under Test.
Light & portable
The XJLink can work with a laptop PC with a USB port and can supply power to low-power target systems, so testing can be done even without a source of mains power. This is especially useful if testing has to be done in the field or in a very busy lab.
The XJLink has variable signal termination, so it can handle boards both with and without signal termination. The advanced auto-skew control enables you to get the maximum frequency out of your JTAG chain and cable.
Simple DLL API interface
The hardware can be sold separately from the software, with a simple-to-use DLL API interface. We can craft the API to meet whatever needs you have for the system.
