2-4 Installation and uninstallation of cable
Note: If any of the below operation is incorrect, turn off the power immediately and check the scanner for
any improper connections. Go through all steps again.
2-4-1 Installation - USB
The scanner attaches directly to a USB host, and is powered by it. No additional power supply is
required.
1. Refer to Figure 2-3, connect the USB interface cable to the bottom of the scanner.
2. Plug the series A connector in the USB host, or an available port of the terminal.
3. Windows will automatically detect the USB device.
Figure 2-4
2-4-2 Installation - RS-232
1. Connect the RS-232 interface cable to the bottom of the scanner.
2. Connect the other end of the interface cable to the serial port on the host. Tighten the two screws to
secure the connector to the port.
3. If the host does not have power supply (on PIN 9), connect the external power supply (DC adapter)
to the RS-232 cable.
Figure 2-5

8
2-4-3 Uninstallation of cable
Figure 2-6
Remove the interface cable:
1. Find the release-hole.
2. Insert a thin wire into the hole and pull out the cable gently.

3 Programming
3-1 Example 1: Single-parameter setting by scanning 1D barcodes
Important notes:
1. During the process of programming, LED is lighting to indicate the programming correctness. LED
will go off if any incorrect programming operation performed.
2. After each successful programming, LED will go off and the scanner will beep twice.
3. Throughout the programming barcode menus, the factory default settings are indicated with
asterisks (*).
Two programming modes have been provided as bellows:
❶Single-scan setting
Scan the appropriate Single-scan setting (e.g. %0101D00%) according to the user‘s demand.
Example: To set Flow control to be XON/XOFF.
Steps: Scan the following barcode.
❷Multiple-scan setting
Step 1. Scan the Option barcode barcode (e.g. %0101M%) according to the user‘s demand.
Step 2. To the right of the option barcode, the necessary alphanumeric inputs are listed. Scan
two alphanumeric entries from 0 to 9 or A to F, refer to 10 Configuration alphanumeric entry
barcode.
Step 3. Repeat Step 2, if more user parameters input are required.
Step 4. Scan the %END% barcode, listed on the lower left hand corner of each parameter
setting part.
Example: To set Flow control to be XON/XOFF.
Steps: Referring to 3-6 RS-232 interface, scan the following barcodes in order.

10
3-2 Example 2: Multiple-parameter setting by scanning a QR code
barcode
User can customize a QR code to set multiple parameters. The scanner can set multiple parameters by
scanning this single QR code barcode.
1. The data format of the QR code barcode is as following.
% Parameter set 1 % Parameter set 2 % Parameter set N %
<Option barcode index><D/H><Alpha. entries>
···
Note that:
<Option barcode index> means the corresponding 4 digits of Option barcode.
<D/H> means “D”or “H”character. D means that the type of alphanumeric entry is decimal; and H
means that the type of alphanumeric entry is hexadecimal.
<Alpha. entries> is a character string with various length of 2, 4, or other values.
Example: Set 0401->03 (decimal); 8002->0D0A (hexadecimal); 8202->01 (decimal). The customized
QR code barcode contents and symbol are as following.
%0401D03%8002H0D0A%8202D01%
2. Notes of making QR code barcode
The model is chosen as M2. Other requirements, e.g. ECC level, Start mode, etc, are not specified.
Other notes
The contents of a QR code barcode can include several same <Option barcode index> associated
with same or different <Alpha. entries>. In the case of with different <Alpha. entries>, the latest
<Alpha. entries> is the valid one.
If any one of the parameter settings is invalid, the total setting is failed. The invalid setting can be
caused by one of the following problems: invalid <Option barcode index>, invalid type of <D/H>,
invalid type, length or value range of <Alpha. entries>, etc.

11
3-3 Operate the scanner by receiving command via UART
Note:
1- The information in this chapter is provided for the scanner with RS232 cable or USB cable.
2- If the scanner is with USB cable, the setting of USB device type must be set as “USB virtual COM”.
Please refer to 3-6 USB interface.
3- Please read 3-7 Scan mode & some global settings about the setting of Scan mode in details.
UART parameter should be set as below:
(1) Baud rate: 9600 bps;
(2) Data bits: 8 bits;
(3) Stop bit: 1 bit;
(4) Parity check bit: None;
(5) Flow control: None.
Guide of control command: all commands are sent by UART
1) Start command: “0x16 0x54 0x0D”
When the scanner received the above command, it will start barcode scanning following the setting of
Scan mode.
2) Stop command: “0x16 0x55 0x0D”
If the Scan mode is set as “Alternate continue”or “Continue”, and the scanner received the above
command, it will stop barcode scanning and act as in an idle mode.

12
3-4 Interface selection
This scanner supports interfaces such as RS-232 serial wedge and USB interface. In most of the cases,
simply selecting an appropriate cable provided by the manufacturer will work for a specific interface.
Interface selection:
Auto detection- By setting this function, the scanner will automatically detect the RS-232 interface or
USB interface for user.

3-5 RS-232 interface
Host type:
Standard- The scanner is connected to a standard RS-232 interface.
OPOS/JPOS- The scanner is connected to a POS terminal which may be necessary to install the
OPOS/JPOS driver to be compatible with the manufacturer's scanner. The OPOS/JPOS driver is
provided by the scanner manufacturer; please contact the scanner manufacturer for the instruction.
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.
XON/XOFF- An XOFF character turns the scanner transmission off until the scanner receives an XON
character.
ACK/NAK- After transmitting data, 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 anACK or NAK. After three unsuccessful attempts to send data when NAKs
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.
