Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The EM3090 OEM scan engine, armed with the Newland patented , a computerized image recognition system, brings about a new era of 2D barcode scan engines. The EM3090’s 2D barcode decoder chip ingeniously blends technology and advanced chip design &... -
Page 8: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the EM3090 and the engine is shipped in ESD safe packaging. Always exercise care when handling the engine outside its package. Be sure grounding wrist straps and properly grounded work areas are used. Dust and Dirt The EM3090 must be sufficiently enclosed to prevent dust particles from gathering on the lens, circuit boards and LEDs. -
Page 9: Installation Orientation
Installation Orientation The following figure illustrates a front view of the EM3090 after installation. Optics Window Placement The window should be positioned properly to let the illumination and aiming beams pass through as much as possible and no reflections back into the engine (reflections can degrade the reading performance). The window should be mounted close to the front of the engine (parallel). -
Page 10: Window Material And Color
Window Material and Color Wavelengths of illumination and aiming beams should be taken into consideration when choosing window material and color, to achieve the possible highest spectral transmission, lowest haze level and homogeneous refractive index. It is suggested to use PMMA or optical glass with spectral transmittance of illumination and aiming beams over 90% and haze less than 1%. -
Page 11: Ambient Light
Ambient Light The EM3090 shows better performance with ambient light. However, high-frequency pulsed light can result in performance degradation. Eye Safety The EM3090 has no lasers. It uses LEDs that create the aiming and illumination beams. These LEDs are bright, but testing has been done to demonstrate that the engine is safe for its intended application under normal usage conditions. -

Page 15: Chapter 4 Interfaces
Chapter 4 Interfaces The following table lists the pin functions of the 12-pin host interface connector on the EM3090. Refer to the “Cable Connection” section in this chapter for the location of Pin 1. PIN# Signal Name Function Power supply. Power supply. -
Page 16: Host Interface Connector
Host Interface Connector The EM3090’s host interface connector is a 12-pin ZIF socket (bottom contact) which can be used to connect a host device (e.g., software development board EVK) with an FFC cable. The following figures show the location and dimensions of the socket. (unit: mm) -
Page 17: Dimensions Of The Host Interface Connector
Dimensions of the Host Interface Connector unit: mm FFC Cable A 12-pin FFC cable can be used to connect the EM3090 to a host device. The cable design must be consistent with the following specifications shown below. Use reinforcement material for the connectors on the cable and reduce cable impedance for reliable connection and stable performance. -
Page 18: Cable Connection
Cable Connection Be sure the power is cut off before connecting a flexible cable to the host interface connector on the EM3090. Hot plugging could damage the engine or the host device. Connect the EM3090 to a host device with a 12-pin flexible cable as shown in the following figure. Communication Interfaces The EM3090 can communicate with the host device through either TTL-232 serial port or USB port using one of the following communication modes. -
Page 19: Control Interfaces
Control Interfaces Reset Driving the RESET pin (PIN 11) on the host interface connector low for 100μs-500μs and then having the signal back to high or idle high level resets the EM3090. The minimum interval between reset operations must exceed 2 seconds. Trigger Driving the TRIG pin (PIN 12) on the host interface connector low for a specified time period causes the EM3090 to start a scan and decode session. -
Page 20: Beeper
Beeper The EM3090 provides a pin (BUZ, PIN 9) on the host interface connector that provides a PWM output to an external driver circuit for generating audible feedback to the user to indicate statuses like power up, good read or operation error. The PWM output is not strong enough to drive a beeper, so a beeper driver circuit is needed. -
Page 21: Good Read Led
Good Read LED The EM3090 provides a pin (LED, PIN 10) on the host interface connector that can be used by an external driver circuit to drive an LED to indicate a good read status. When a good read occurs, the signal from the LED pin turns from a low level into alternation of high and low levels and a while later back to a low level. -
Page 22: Chapter 5 Development Tools
Chapter 5 Development Tools The EM3090’s development tools can be utilized for engine performance evaluation, application development and engine configuration. The EVK is provided to help users to test and evaluate the EM3090, which contains beeper & beeper driver circuit, LED & LED driver circuit, trigger & reset buttons, TTL-232 to RS-232 converter & TTL-232 to USB converter, RS-232 &... - Page 23 Headquarters Fujian Newland Auto-ID Tech.
