Communication principle experiment box Teaching didactic module
EQUIPMENTOVERVIEW
The main board and modular structure are adopted, and each module has a standard structure,
signal input and output interface, clock bus and communication bus interface. Built-in independent
optical power meter and error meter module.
Provide physical protection
The modules have the same size and structure, and the upper and lower layers of protective
cover are used to protect the modules in a full range, and the upper layer is a transparent shell
for easy observation. In addition, the upper and lower protective shells of the module are connected
with bayonets for easy disassembly (screw free installation), which is convenient for experimental
teaching and module maintenance.
Self-designed chip protection scheme
The circuit module uses a convenient replaceable pin package bus driver to isolate the I/0 test
point of the test circuit and the function chip, which can effectively prevent the wrong operation
of the test port connection and the damage of the function chip of the test circuit.
Each module is equipped with an independent power switch
Each module of the experiment box is equipped with an independent multi-channel power switch.
tudents can turn each module on and off independently according to the actual situation.
Each module is relatively independent, which can prolong the product life and improve the reliability
of the product.
