This chapter describes the timing associated with the various operating modes of the MT84G including Power Up, Sleep Mode, and Decode Timing. When power is initially applied, the MT84G is activated and begins the process of initialization. Once initialization (duration≧1000mS) is completed, the MT84G emits power-up beeps, enters Standby Mode and is ready for barcode scanning. -

Scanning above barcode will set your MT84G to USB VCP interface. 1. At power-up, the MT84G sends the Power-Up (PWM) signals over Buzzer pin as an indication that the MT84G enters Standby Mode and is ready for operation. 2. Once the MT84G triggered by either hardware or software method, it will emit white illumination with a narrow, horizontal slab of red light which helps user target the barcode. -
