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 2-3

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 2-4

2-4-3

Uninstallation of cable

Figure 2-5

Remove the interface cable:

1. Find the release-hole.

2. Insert a thin wire into the hole and pull out the cable gently.

2-5 Assembling the stand

Note: The stand is an optional accessory.

1. See the figure above, tighten the screws.

2. Bend the neck to the desired position for scanning.

3. Screw mounting: Screw one #10 wood screw into each screw-mount-hole until the base of the stand

is secured.

4. Tape mounting: ①Peel the paper liner off one side of each piece of tape and place the sticky surface

over each of the three rectangular tape holders. ②Peel the paper liner off the exposed sides of each

piece of tape and press the stand on a flat surface until it is secure.

10

2-6 Auto-

detection

Note: The stand is an optional accessory.

1. To scan a barcode, present the barcode and ensure that the scan angle from the scan window

can cover the barcode.

2. Upon successful decode, the scanner beeps and the LED lights.

3. When the scanner stops scanning, the present barcode must be removed to active next

scanning.

Figure 2-7

The scanner offers 2 methods to enable/disable Auto-detection quickly.

Method 1

Scan the barcode “EN-AutoDete” on the stand to enable Auto-detection.

Scan the barcode “DIS-AutoDete” on the stand to disable Auto-detection. Note: The

Scanning mode will switch to momentary.

See Figure 2-8.

Method 2

Scan the barcode “%%SWAM” to enable Auto-detection.

Scan the barcode “%%SWLM” to disable Auto-detection. Note: The Scanning mode

will switch to momentary.

See 8 Quick setting to enable/disable Auto-detection.

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:

❶ Single-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.

❷ Multiple-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 3-5 RS-232 interface, scan the following barcodes in order.

3-2 Example

2: Multiple-parameter setting by scanning a QR code barcode

User can customize a QR code barcode 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 %

···

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: “0x54” (T)

When the scanner received the above command, it will start barcode scanning following the setting

of Scan mode. If the scanner is in the mode of “Auto-detection”, the scanner will have a single

scan, then returns to “Auto-detection” mode.

2) Stop command: “0x50” (P)

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) Restart command: “0x35” (R)

Once the scanner received the above command, it will restart.

Returning message from the scanner

1) A successful decode

Once the scanner successfully decoded a barcode, the scanner will stop scanning and returns

the barcode data to the Host.

2) Not a successful decode

Once the scanner failed to decode a barcode before stopping scanning, the scanner will return a

message to the Host. The message is set as “0x25, 0x25, 0x4E, 0x6F, 0x52, 0x65, 0x61, 0x64”

(%%NoRead).
