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.

9
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.

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.

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 an ACK 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.
