Chapter 1 Getting Started
Introduction
The NLS-EM3095 OEM scan engine, armed with the Newland patented , a computerized image
recognition system, brings about a new era of 2D barcode scan engines.
The EM3095 ingeniously blends 2D barcode decoder chip technology and advanced chip design
& manufacturing, which significantly simplifies application design and delivers superior performance and
solid reliability with low power consumption.
The EM3095 supports all mainstream 1D as well as PDF417, QR Code (QR1, QR2, Micro QR), Data
Matrix and GS1-DataBarTM(RSS) (RSS-Limited, RSS-14, RSS-14 Stacked and RSS-Expand).
The EM3095 can read barcodes on virtually any medium - paper, plastic card, mobile phones and LCD
displays. It provides an ideal solution for both emerging mobile phone-based barcode applications, like
coupons, e-tickets and boarding passes, and traditional applications.
This compact engine weighs only 4.4 grams and fits easily into even the most space-constrained
equipments such as data collectors, meter readers, ticket validators and PDAs. Moreover, the instant
power on/off feature along with ultra low power consumption brings greater efficiency and convenience in
barcode scanning.

About This Guide
This guide provides programming instructions for the EM3095. Users can configure the EM3095 by
scanning the programming barcodes included in this manual.
The EM3095 has been properly configured for most applications and can be put into use without further
configuration. Users may check the Factory Defaults Table in Appendix for reference. Throughout the
manual, programming barcodes marked with asterisks (**) are factory default values.
Connecting EVK and PC
The EVK tool is provided to assist users in application development for the EM3095. The EM3095 can be
connected to the EVK via a 12-pin flat flexible cable. Either USB connection or RS-232 connection can be
used when connecting the EVK to PC. A driver is required if EVK wants to communicate with EM3095
and receive decoded data through USB COM port.
Barcode Scanning
Powered by area-imaging technology and Newland patented technology, the EM3095 features
fast scanning and accurate decoding. Barcodes rotated at any angle can still be read with ease. When
scanning a barcode, simply center the aiming pattern projected by the EM3095 over the barcode.
Configuring the EM3095
There are two ways to configure the engine: barcode programming and command programming.
Barcode Programming
The EM3095 can be configured by scanning programming barcodes. All user programmable
features/options are described along with their programming barcodes/commands in the following
sections.

3
Command Programming
Besides the barcode programming method, the EM3095 can also be configured by serial commands sent
from the host device. Note that communication parameters on the engine and the host must match so
that two devices can communicate with each other. The default settings of the engine are 9600bps, no
parity check, 8 data bits, 1 stop bit, and no flow control. The engine uses 8-bit registers.
Read Register
The read command is used to read the contents of 1 to 256 contiguous registers in the engine.
Syntax: {Prefix1} {Types} {Lens} {Address} {Datas} {FCS}
Prefix1 : 0x7E 0x00
Types : 0x07
Lens : 0x01
Address: 0x0000~0x00FF, starting register address.
Datas : 0x00~0xFF, number of registers to be read. When Datas=0x00, 256 contiguous
registers are to be read.
FCS : CRC-CCITT checksum, 2 bytes.
Computation sequence: Types+ Lens+Address+Datas;
polynomial: X16+X12+X5+1 (0x1021), initial value: 0x0000.
The following C language program is provided for reference.

4
unsigned int crc_cal_by_bit(unsigned char* ptr, unsigned int len)
{
unsigned int crc = 0;
while(len-- != 0)
{
for(unsigned char i = 0x80; i != 0; i /= 2)
{
crc *= 2;
if((crc&0x10000) !=0)
crc ^= 0x11021;
if((*ptr&i) != 0)
crc ^= 0x1021;
}
ptr++;
}
return crc;
}

Reply: {Prefix2} {Types} {Lens} {Datas} {FCS}
1) Success message:
Prefix2 : 0x02 0x00
Types : 0x00 (success)
Lens : The number of data returned. If Lens=0x00, that means values of 256 contiguous
registers are returned.
Datas : 0x00~0xFF, data that are returned.
FCS : CRC-CCITT checksum.
2) CRC check failure message:
Prefix2 : 0x02 0x00
Types : 0x01 (CRC check failure)
Lens : 0x01
Datas : 0x00
FCS : CRC-CCITT checksum (0x04 0x01)
3) Invalid command message:
Prefix2 : 0x02 0x00
Types : 0x03 (invalid command)
Lens : 0x01
Datas : 0x00
FCS : CRC-CCITT checksum (0x6A 0x61)

Example:
Read the content (0x3E) of register 0x000A
1) Read operation succeeds:
Command sent: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01 0xEE 0x8A
Message received: 0x02 0x00 0x00 0x01 0x3E 0xE4 0xAC
2) CRC check fails:
Command sent: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01 0x11 0x22
Message received: 0x02 0x00 0x01 0x01 0x00 0x04 0x01
3) Situations that may cause the engine to respond with an invalid command message: Command sent is
shorter than the required length, or the third byte is not sent out within 400ms after the first two bytes
“0x7e 0x00” are sent
Command sent: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01
Message received:0x02 0x00 0x03 0x01 0x00 0x6A 0x61

7
Write Register
The write command is used to write contiguous registers (1 to 256 registers) in the engine.
Syntax: {Prefix1} {Types} {Lens} {Address} {Datas} {FCS}
Prefix1 : 0x7E 0x00 (2 bytes)
Types : 0x08 (1 byte)
Lens : 0x00~0xFF (1 byte), byte count, i.e. number of registers written. When Lens=0x00, 256
contiguous registers are to be written.
Address : 0x0000~0xFFFF (2 bytes), starting register address.
Datas : 0x00~0xFF (1~256 bytes), data to be written into the register(s)
FCS : CRC-CCITT checksum, 2 bytes.
Computation sequence: Types+ Lens+Address+Datas; polynomial: X16+X12+X5+1
(0x1021), initial value: 0x0000.
The following C language program is provided for reference.
