Chapter 1 Getting Started
Introduction
The RT211 hand-held barcode scanner (hereinafter referred to as “RT211 scanner” or “the scanner”),
armed with a computerized image recognition system-on-chip, bring about a new era of 2D barcode scanner.
The RT211’s 2D barcode decoder chip ingeniously blends image recognition algorithm and advanced chip
design & manufacturing, which significantly simplifies application design and delivers superior performance
and solid reliability with low power consumption.
The RT211 supports all mainstream 1D and standard 2D barcode symbologies (e.g., PDF417, QR Code, Data
Matrix and Chinese Sensible Code) as well as GS1-DataBarTM(RSS) (Limited/Stacked/Expanded versions). It
can read barcodes on virtually any medium - paper, plastic card, mobile phones and LCD displays.
This compact, lightweight engine fits easily into even the most space-constrained equipment such as
data collectors, meter readers, ticket validators and PDAs.
The RT211's instant start-up feature allows for a complete shutdown of the current in the application.
Instantly starting bar code recognition when needed, and bring convenience and quickness to applications
with ultra-low power consumption.
About This Guide
This guide provides programming instructions for the RT211. Users can configure the RT211 by scanning the
programming barcodes included in this manual.
The RT211 has been properly configured for most applications and can be put into use without further
configuration. Users may check Appendix A: Factory Defaults Table for reference. Throughout the manual,
asterisks (**) indicate factory default values.

Connecting EVK to PC
The EVK tool is provided to assist users in application development for the RT211. You can connect
the EVK to PC via a USB connection or an RS-232 connection. In case of USB connection, a driver is
required if PC wants to communicate with RT211 and receive decoded data through virtual serial
port.
Barcode Scanning
Powered by area-imaging technology, the RT211 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 beam or pattern projected by the RT211 over the barcode.
Barcode Programming
The user can use the setup bar code or serial port instructions to set the reading engine.

RT211 User Guide
Configuring the RT211
There are two ways to configure the scanner: barcode programming and command programming.
Barcode Programming
The scanner can be configured by scanning programming barcodes. All user programmable features/options
are described along with their programming barcodes/commands in the following sections.
Command Programming
Besides the barcode programming method, the scanner can also be configured by serial commands sent from
the host device. Note that communication parameters on the scanner and the host must match so that two
devices can communicate with each other. The default settings of the scanner are 9600bps, no parity check, 8
data bits, 1 stop bit, and no flow control. The scanner uses 8-bit registers.

Read Register
The read command is used to read the contents of 1 to 256 contiguous registers in the scanner.
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;
calculate method is CRC_CCITT
polynomial: X16+X12+X5+1(0x1021), initial value: 0x0000.
The highest bit is calculated first for a single byte, and there is no need to invert the direct
output. The following C language program is provided for reference.
