Introduction The E3000H barcode reading engine uses the world's leading intelligent image recognition technology to combine advanced image recognition algorithms with advanced chip design and manufacturing technology, which greatly simplifies the design difficulty of one-dimensional barcode reading products and establishes one-dimensional images. An excellent benchmark for high performance, high reliability and low power consumption.

Chapter 1 Introduction General Requiremetns ESD The E3000H has been designed to protect against static electricity and uses anti-static packaging. However, anti-static measures should be taken during unpacking and use, such as grounding wrist straps and grounding of the work area. Dustproof The E3000H must be sufficiently sealed during storage and use to prevent dust, particles or other contaminants from adhering to the lens, circuit board, etc.
Chapter 2 Installation Mounting orientation When the E3000H is properly placed or installed, its front view looks like the picture below. In the middle is the lens, the two sides are aimed, the upper is the decoding circuit board, and the screw mounting holes are below. At this time, the relative orientation of the image captured by the E3000H correctly corresponds to its orientation.
Window material and color The material and color of the window should be chosen in consideration of the illumination of the E3000H and the wavelength of the light wave that the CIS can respond to (mainly red and white), so that the light transmittance is as high as possible, while ensuring the lowest possible blur and uniform refractive index. . PMMA or optical glass is usually used, and the window material has a red light transmittance of more than 90% and a haze of less than 1%.

Chapter 3 Electrical characteristics Power requirement Power input must be allowed after the E3000H is connected. If the E3000H (with hot plug) is plugged or unplugged while the cable is live, the electronic components of the E3000H may be damaged. Make sure that the power is turned off while the cable is being inserted.

第四章 接口 Chapter 4 Interface Interface Description The table below lists the names and signal descriptions for the individual pins of the E3000H's 12-pin connector. Instruction PIN# Signal Name I/O 1 NC NC - 2 VDD - 3.
Connector The figure below is a schematic of the E3000H connector. It uses a ZIF 12 PIN lower contact socket and is connected to the peripheral (host) with a flexible cable. The lower icon shows the size of the socket (unit: mm). Flat Cable The 12PIN flexible cable used in the E3000H connector can be designed as the same or different-sided cable according to the application. The specifications must meet the following requirements.
Communication Interface : The E3000H communicates with the host computer in the following ways: TTL TTL level signal (TTL-232): This interface accommodates most system architectures. For some systems that require an RS-232 form factor, a TTL-232 to RS-232 conversion circuit is required. USB HID-KBW: A USB-based keyboard emulation device that can be directly connected to a PC without the need to install a driver.
When the E3000H is started, the reading is successful, etc., the PWM signal is output on the Buzz pin according to the setting. The signal output can drive the buzzer to sound a sound through an external matching circuit. The Buzz pin has limited load capacity and cannot directly drive the buzzer to sound, so as not to damage the chip on the E3000H.
Decode LED signal The LED (PIN 10) pin of the E3000H provides a level cue signal when decoding is successful, and is typically used as an input control signal for externally decoded LED cues. When the decoding is successful, the LED pin will output a high-level pulse with a duration of approximately 300ms and eventually return to a low level. The LED signal output pin has a limited load capacity and cannot directly drive the LED. A matching LED driver circuit is required.
