The Universal Debug Probe
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.
- Additional Ethernet interface
- Download speed up to 3 MByte/s
- Superset of J-Link ULTRA+

About J-Link PRO
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.
