10.6 Description of the Interface
USB interface:
It is a standard and common configuration with the advantages of fast transmitting, high
reliability, convenient linking and instant inserting/plugging.
It is a common and widely-used interface.
USB interface
USB interface accords with the regulations of USB V1.1.
Interface down-wire:
power wire: +5V, GND
signal wire: D+, D- , bi-direction and tri-state.
Interface linking:
Plug one end of the USB transmitting cable wire into the USB interface socket on the
front panel and the other end into the USB interface socket on the computer.
