I. Product Introduction

51/96 SCM Principle Experiment Apparatus is tightly close to such teaching syllabus as SCM Principle, SCM Control technology, Automatic control. It has comprehensive experiment contents, which could fully meet the experiment teaching requirements of Electronic communications, Computer, Automation among colleges and universities.

1. The experiment apparatus has a flexibly and open structure, all the circuit units are nearly independently open to improve flexibility of the experiment. Each unit module is free to build experiment circuit to leave creation space for students thus improve resource utilization. For example, the open keyboard, open displayer and the open serial ports etc to adapt various experiments.
2. Expansion slots are left on the motherboard, which are convenient for development extension.
3. The system integrates 51/96 universal SCM emulator, 64K data space, fully open 64K program space which doesn’t occupy the CPU; adopt dual-CPU mode; Emulation-CPU and experiment-CPU run independently; Software support compiling, PL / M, C language, stable performance.
4. The system supports two working ways: on-line and off-line operation. On-line: In line with the upper software, various operations of deb ing and running can be realized; Offline operation: with management monitor. In the absence of simulator, the system can switch to the state of offline management automatically thus users can call the experiment programs freely to complete 52 experiments.
5. The system equips with 51/96 universal SCM emulator of excellent function which can adapt debug software of Windows98/2000/xp operating platform.
