SEGGER J-Link PRO

J-Link PRO is a refined version of the regular J-Link. It has an Ethernet interface in addition to the USB interface, as well as two additional LEDs which are used as hardware status indicators. It connects via Ethernet or USB to the host, running Windows, Linux or macOS.

J-Link Debug Probes ➦

J-Link PRO is fully compatible with J-Link and can be used "out-of-the-box". J-Link PRO uses DHCP per default. The built-in webserver makes manual configuration easy. Ethernet allows using the debug probe far away from the PC, over a hardwired or wireless network, in a development or production environment; download and debugging speed is higher and Ethernet provides electrical isolation from the PC. All features of the regular J-Link also apply to this product.

Speed

Up to 3 MByte/s download speed make J-Link PRO the fastest debug probe on the market. Using TCP/IP instead of USB eliminates latencies from USB usage, resulting in higher debugging speed.

Flexibility

Due to the Ethernet interface, long distances between the development PC and the target system are possible. You can set a default gateway for J-Link PRO, so it is also possible to use it in large intranets.

Security (Galvanic isolation)

Ethernet signal lines provide galvanic isolation of J-Link PRO (and so the target system) from the network and development PC.
