Newland’s SDK. ※ Note: This guide provides general instructions for the installation of the engine into a customer's device. Fujian Newland Auto-ID Tech. Co., Ltd. recommends an opto-mechanical engineer should conduct an opto-mechanical analysis before integration.
Chapter 1 Getting Started Introduction The EM50S is an area image engine for barcode reading. It includes a laser aiming system, an LED illumination system and a 12-pin FPC connector. LED Compliance Statement The EM50S complies with IEC 62471:2006 for LED safety. Laser Compliance Statement The EM50S is certified to be in compliance with IEC 60825-1:2014 as a class 1 laser product.
Figure 1-1 System Block Diagram Illumination Aimer 12-pin Connector CMOS The 12-pin FPC connector on the engine can be connected to a host device with an FFC cable. For information about this cable, please see the “12-pin FFC Cable” section in Chapter 4. Illumination The EM50S has a white LED for supplementary lighting, making it possible to scan barcodes even in complete darkness.
Chapter 2 Installation Introduction This chapter explains how to install the EM50S, including general requirements, housing design, and physical and optical information. △ Caution: Do not touch the imaging lens when installing the engine. Be careful not to leave fingerprints on the lens. !...
CPU, CIS, LEDs, DC/DC, etc and could result in a 40° C (EM50S-10) /35° C (EM50S-20) increase inside the engine. Overheating can degrade image quality and affect scanning performance. Given that, the following precautions should be taken into consideration when integrating the EM50S.
The EM50S series include two models -- EM50S-10 and EM50S-20 -- to cater for different mounting needs. For the EM50S-10 (the decoder board and the imager already assembled as one), the user can just mount the assembled unit on the target device.
EM50S-20: Figure 2-7 Housing Design ※ Note: Conduct an optical analysis for the housing design to ensure optimal scanning and imaging performance. Housing design should make sure that internal reflections from the aiming and illumination system are not directed back to the engine.
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 of the engine). There are two window placement options. •...
Window Material and Color Window material must be clear. Use only cell-cast plastics or optical glass. PMMA, ADC and chemically tempered glass are recommended. Window material selected for the engine should meet or exceed the specifications specified in Table 2-4. •...
The AR coating specifications below should be met when using an AR coated window. Single side AR coating: 92% minimum transmittance within spectrum range from 420 nm to 730 nm. Double side AR coating: 97% minimum transmittance within spectrum range from 420 nm to 730 nm. Window Size The window must not block the field of view and should be sized to accommodate the aiming and illumination envelopes shown below.
Three different reading angles, roll, skew and pitch are illustrated in Figure 2-10 Roll refers to rotation around the Z axis, skew to rotation around the X axis and pitch to rotation around the Y axis. For the engine’s technical specifications, please visit the Newland website or contact your dealer. Figure 2-11 Ambient Light The EM50S shows better performance with ambient light.
Chapter 3 Electrical Specifications Power Supply Do not power up the EM50S until it is properly connected. Be sure the power is cut off before connecting a cable to or disconnecting a cable from the host interface connector. Hot-plugging could damage the engine. Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable performance of the engine.
I/O Voltage Table 3-2 VDD=3.3 V, VSS=0 V, T=23° C Parameter Minimum Maximum Unit Timing Sequence Power Up and Power Down Timing Sequence Figure 3-1 1. In the diagram above, it takes A+B (less than 1s) for the engine to power up: A is reset time (about 560ms), B is time needed to start the engine (including bootloader execution, kernel boot and decoding chip initialization).
Chapter 4 Interfaces Interface Pinouts The host interface connector of the EM50S is a 12-pin FPC connector, which can be used as TTL-232 interface or USB interface. The figure below illustrates the position of 12-pin FPC connector on the EM50S’s decoder board, as well as the pin 1 location.
12-pin FPC Connector The following table lists the pin functions of the 12-pin FPC connector. Table 4-1 PIN# Signal Function Remark PIN1 No connection 3.3V power supply input Power-supply ground TTL level 232 receive data TTL level 232 transmit data USB_D- USB D- differential data signal USB_D+...

※ 3 This output signal can be used by an external LED to indicate good read status. The LED pin (PIN 10) produces a low output (default duration: 20ms, user-programmable) when a good read occurs. The Good Read LED can be programmed On or Off. To learn how to program these parameters, please see the EM50S user guide.
Connector/Cable Specifications (Unit: mm) The EM50S is equipped with a 12-pin FPC connector. 12-pin FPC Connector The 12-pin FPC connector on the EM50S is supplied by Hirose Electric Co., Ltd. Model No.: FH34SRJ-12S-0.5SH(50), dual contact. Figure 4-2...
External Circuit Design Good Read LED Circuit The circuit below can be used to drive an external LED for indicating good read. The LED signal is from PIN 10 of the 12-pin FPC connector. Figure 4-4 Beeper Circuit The circuit below can be used to drive an external beeper. The BUZ signal is from PIN 9 of the 12-pin FPC connector. Figure 4-5...
Trigger Circuit The circuit below can be used to provide the engine with a signal to trigger a scan and decode session. The nTRIG signal is from PIN 12 of the 12-pin FPC connector. Figure 4-6 External Illumination LED Circuit The circuit below can be used to control external illumination LED when the user wants to add external illumination to further improve lighting.
Reset Circuit The circuit below can be used to reset the engine by giving a 200μs low pulse on the nRESET pin (PIN 11) on the host interface. The host device can send the RESET signal through GPIO. Figure 4-8...
The EM50S can be connected to the EVK via a 12-pin FFC cable type 1 (contacts on the same side). Either USB connection or RS-232 connection can be used when connecting the EVK to a host device. EasySet EasySet is a Windows-based configuration tool developed by Newland, which can be used to configure the EM50S.
