Notice
Make sure you carefully read the following information to ensure that your barcode scanner is able to
perform at the level for which it is designed.
All software, including firmware, furnished to the user is on a licensed basis.
The right is reserved to make changes to any software or product to improve reliability, function, or
design.
The material in this manual is subject to change without notice.
The manufacturer assumes no responsibility for any loss or claim by third parties which may arise
from the use of this manual.
Do not throw or drop the scanner or otherwise subject it to strong impact, which can damage the
scanner, interrupt program execution, corrupt memory contents, or otherwise interfere with proper
operation.
Different version of the barcode scanner may have different software function, please confirm the
corresponding version of software.

Notes about structure and electric circuit design
1. Suggest using non-magnetic screws, when mounting the scanner. Magnetic screws can cause
element/mirror neutral position to change.
2. It is recommended to use a thread locking method, such as a Nylok patch.
3. Do not place magnetic material (e.g. dynamic speakers, ringers, vibrators, inductors, metal parts)
within 1 inch of the scanner chassis. Evaluate placement of all magnetic or ferrous material during
system layout to determine if 1 inch is sufficient.
4. Leave sufficient space to accommodate the maximum size of the scanner.
5. Read section “ 1-2 Electrical interface/Pin assignment ”, carefully to learn about the electrical
interface design.

2 Installation guide
2-1 Important notes of installation
ESD
The scanner needs to protected from ESD events that may occur in an ESD-controlled environment.
Magnetism
Mounting screws must be non-magnetic material. Do not place any magnetic material within 1 inch/ 2.54
cm of the chassis without testing.
2-2 Mounting
There are four mounting holes (M2) on the top of the chassis and it is shown in Figure 2-1.

3-1 Example: Configure scanner by scanning configuration barcodes
Throughout the programming barcode menus, the factory default settings are indicated with
asterisks (*).
❶Single-scan setting
Scan the appropriate Single-scan setting according to the user‘s demand.
Example: to set Flow control to be ACK/NAK.
Steps: Scan the following barcode.
❷Multiple-scan setting
The steps of configuration are:
1) Scan the SETUP barcode on the parameter setting part.
2) Enter the option mode by scanning the Parameter name barcode.
3) To the right of the option barcode, the necessary alphanumeric inputs are listed. Scan these
alphanumeric entries.
4) Scan the END barcode, listed on the bottom of each parameter setting part.
5) Notes that only one parameter can be setup at each time.
Example: to set Flow control to be none.
Steps: Scan the following barcodes in order.

3-2 RS-232 interface
Flow control:
None-The communication only uses TXD and RXD signals without any hardware or software
handshaking protocol.
RTS/CTS-If the scanner wants to send the barcode data to host computer, it will issue the RTS
signal first, wait for the CTS signal from the host computer, and then perform the normal data
communication. If there is no replied CTS signal from the host computer after the timeout duration,
the scanner will issue an error indication. By setting (Host idle: Low RTS or Host idle: High RTS), the
scanner can be set to match the Serial Host RTS line.
ACK/NAK-After data transmitted, the scanner expects either an ACK (acknowledge) or NAK (not
acknowledge) response from the host. When a NAK is received, the scanner transmits the same
data again and waits for either an ACK or NAK. After three unsuccessful attempts to send data when
NAK are received, the scanner issues an error indication and discards the data.
Inter-character delay: This delay is inserted after each data character transmitted.
Response delay: This delay is used for serial communication of the scanner when it waits for a
handshaking acknowledgment from the host.
Host-character delay: This delay is the time that the scanner waits for the host to send the next character
in serial communication, it is based on 1ms increments.
Data package:
Disable: The scanner sends the decoded data directly.
Enable: The decoded data is sent in data package mode (see section “ 4-4 DECODE_DATA ”).

3-3 USB interface
USB device type:
HID keyboard–By setting, the scanner is used as a USB HID keyboard emulation device.
USB virtual COM–By setting, the scanner emulate a regular RS232-based COM port. If a Microsoft
Windows PC is connected to the scanner, a driver is required to install on the connected PC. The
driver will use the next available COM Port number. The driver and the installation guide can be found
in the associated CD and on the manufacturer’s website. A Windows-based software COM_Text is
recommended to display the barcode data in text format. COM_Text emulates some kind of serial-key
typing.
The scanner will send the data in data package by the USB interface, if the data package is enabled
(see section " 3-2 RS-232 Interface "). while the USB works in USB virtual serial port operating mode,
the USB virtual serial port will follow the ACK / NAK flow control, if the RS232 interface uses ACK /
NAK flow control.
Simple COM Port Emulation- Please contact the manufacturer for the instruction.
Note: After changing USB Device Types, the scanner will automatically restart.
Keyboard layout: The scanner supports different national keyboard layouts.
Inter-character delay: This delay is inserted after each data character transmitted.
Numeric key:
Alphabetic key- the scanner will output code result as alphabetic key.
Numeric key- the scanner will output code result as pressing numeric keypad ( ‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’,
‘7’, ‘8’, ‘9’, ‘.’, ‘+’, ‘-‘, ‘/’, ‘*’only).
Alt+ keypad- the scanner will output code result as pressing Alt+ numeric key (on keypad). Note that
the Num Lock control key must be ON. This setting can be specially adapted for use with different
national keyboard layout.
