Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The EM1395 embedded 1D barcode scan engine, armed with linear imager and Newland patented image recognition system, can read barcodes on a variety of mediums like paper and magnetic cards and is suitable to be integrated into various OEM devices including handheld barcode scanners, PDAs and kiosks. -
Page 8: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the EM1395 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 EM1395 must be sufficiently enclosed to prevent dust particles from gathering on the imager, lens and circuit board. -
Page 9: Installation Orientation
Installation Orientation The following figure illustrates a front view of the EM1395 after proper installation. -
Page 10: Optics
Optics Window Placement The window should be positioned properly to let the illumination beam 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). The maximum distance is measured from the front of the engine housing to the farthest surface of the window. -
Page 11: Window Size
Window Size The window must not block the field of view and should be sized to accommodate the illumination envelopes shown below. Ambient Light The EM1395 shows better performance with ambient light and it is well able to handle the flicker in fluorescent lights using 50-60Hz AC power. -
Page 12: Mounting
Mounting The illustrations below show the mechanical mounting dimensions for the EM1395. The structural design should leave some space between components and reserve enough room for the flat flexible cable. Front View (unit: mm) Top View (unit: mm) Bottom View (unit: mm) -
Page 13: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM1395 until it is properly connected. Be sure the power is cut off before connecting a flexible cable to or disconnecting a flexible cable from the host interface connector. Hot-plugging could damage the engine. -

Page 15: Chapter 4 Interfaces
Chapter 4 Interfaces Host Interface Connector The following table lists the pin functions of the 12-pin host interface connector on the EM1395. - Page 16 PIN# Signal Name Function When low, the engine enters the Download mode after being repowered; when high, the engine enters the Normal mode after Flash_DOWN being repowered. If this function is not required, leave this pin unconnected. 3.3V power supply. Power-supply ground.

Page 17: Dimensions Of The Host Interface Connector (Unit: Mm)
Dimensions of the Host Interface Connector (unit: mm) The engine uses a 12-pin ZIF socket (bottom contact, model: 10051922-1210ELF/ 10051922-1210EHLF) manufactured by FCI. The socket can be connected to a host device with a flat flexible cable. -
Page 18: Flat Flexible Cable (Unit: Mm)
Flat Flexible Cable (unit: mm) A 12-pin flat flexible cable can be used to connect the EM1395 to a host device. The cable design must be consistent with the specifications shown below. Use reinforcement material for the connectors on the cable and reduce cable impedance for reliable connection and stable performance. -
Page 19: Communication Protocol
Communication Protocol The following describes how the host sends a command to the EM1395. Step 1: The host lowers the CTS (to request to send), then checks the state of the RTS. Step 2: When the engine detects the CTS is low, it lowers the RTS (to grant permission). Step 3: When the host detects the RTS is low, it asserts the CTS (to remove request), then check the state of the RTS. - Page 20 The EM1395 also supports the other host initiated transaction which is based on the one illustrated above: Execute steps 5-6 only. Advantage: Steps 1-4 are skipped. Disadvantage: If the engine is in shallow sleep, this transaction can still function, but it becomes impossible if the engine enters deep sleep.

Page 21: Trigger
Trigger Driving the TRIG pin (PIN 12) on the host interface connector low for over 10ms causes the EM1395 to start a scan and decode session. If barcode is decoded, the EM1395 waits for the voltage at the TRIG pin to turn high (or the trigger to be released) after sending the data to the Host. -
Page 22: Beeper
Beeper The EM1395 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 or good decode. The PWM output is not strong enough to drive a beeper, thus a beeper driver circuit is needed. -
Page 23: Good Read Led
Good Read LED The EM1395 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 LED pin gets pulled low for about 300ms, and then the signal is back to a high level. -
