The Signum JDSNET 2XLP is an in-circuit emulator for real-time debugging and emulation of embedded systems. It connects to a host PC via parallel port or optional Ethernet, providing deep insight into target system operation through hardware breakpoints, register/memory access, code tracing, and optional trace buffering. The adapter pod interfaces with various processor packages via JTAG, supporting TMS320 DSP families, 8051 microcontrollers, and other architectures.
