Introduction to installation 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. Installation - keyboard wedge 1. Switch off the host and unplug the keyboard connector. 2. Attach the modular connector of the Y-cable to the cable interface port on the scanner. 3. Connect the round male DIN host connector of the Y-cable to the keyboard port on the host device. 4.
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 5, 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.
Scanning modes The scanner has two scanning modes: hand-held and auto-detection. When the scanner is scanning, ensure the scan line crosses every bar and space of the symbol. RIGHT WRONG Figure 6 The auto-detection scanning mode has two operating modes: in-stand and always ON. The following is an introduction to in-stand auto-detection mode. 1. When the scanner is seated in the stand, the scanner operates in auto-detection mode (see Figure 7). 2.
Programming instruction Refer to the next page, the steps of programming are: 1. Scan the SETUP bar code on the parameter setting part. 2. Enter the option mode by scanning the Option bar code. 3. To the right of the option barcode, the necessary alphanumeric inputs are listed. Scan these alphanumeric entries. 4. Scan the END bar code, listed on the lower right hand corner of each parameter setting part. 5. Notes that only one parameter can be setup at each time. 6.
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 chapter of “USB interface”. 3- Please read the chapter of “Scanning & some global settings” about the setting of Scanning mode in details.
Interface selection This scanner supports interfaces such as keyboard wedge, 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 keyboard wedge, RS-232 or USB interface for user. SETUP Option bar code Option Auto detection (Keyboard Interface selection Alpha.
Keyboard wedge Keyboard type: As a keyboard interface, the scanner supports most of the popular PCs and IBM terminals. Keyboard layout: The scanner supports different national keyboard layouts. Clock period: According to the PS2 protocol, the clock is provided by the device, e.g. keyboard or scanner, with the period between 60us to 100us.

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.

USB interface USB device type: HID keyboard– By setting, the scanner is used as a USB HID keyboard emulation device. The keyboard layout setting follows the setting of keyboard layout in the chapter of Keyboard wedge. USB virtual COM– By setting, the scanner is used as a USB virtual COM emulation device. A software driver is required to install on the connected PC. The information can be found in the associated CD. Note: when changing USB Device Types, the scanner automatically restarts.

Hand-held scan & some global settings Scanning mode: Good-read off-The trigger button must be pressed once to activate scanning. The light source of scanner stops scanning when there is a successful reading or no code is decoded after the Stand-by duration elapsed. Momentary-The trigger button acts as a switch. Press button to activate scanning and release button to stop scanning.
i.e. in ASCII from 20H to 7EH. Alphanumeric character only- If this option is selected, the scanner will output the alphanumeric characters only, i.e. “A”-“Z”, “a”-“z”, “0”-“9”. Decoder optimization: If it is enabled, the scanner will optimize the decoder with error correction. This function is not effective for all types of barcodes. Data output delay in continue-scan mode: If it is enabled, in the continue-scan mode, the scanner can store the data while continue-scanning. elapsed.

Indication Power on alert: After power-on the scanner will generate an alert signal to indicate a successful self-test. LED indication: After each successful reading, the LED above the scanner will light up to indicate a good barcode reading. Beeper indication: After each successful reading, the scanner will beep to indicate a good barcode reading, and its beep tone duration is adjustable. Beep tone duration: This parameter can be adjusted for a good reading upon favorite usage.
Auto-detection scan Auto-detect sensor: By setting Enable, the scanner will start operating if any nearby object has been detected. The laser light of scanner stops scanning when there is a successful reading or no code is decoded after the Stand-by duration elapsed. Once the laser light stops scanning, the present object must be removed to enable Auto-detect sensor. Operating mode: In stand-The scanner must be placed in the stand to enable Auto-detect sensor.

Maintenance Cleaning the exit window is the only maintenance required. A dirty window may affect scanning accuracy. 1. Do not allow any abrasive material to touch the window. 2. Remove any dirt particles with a damp cloth. 3. Wipe the window using a tissue moistened with water. 4. Do not spray water or other cleaning liquids directly into the window. 5. Use a piece of soft and dry cloth when cleaning the scanner.
Assembling the stand 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.

Barcode representing non-printable character Notes to make the following barcode: 1. According to different barcode printing software, the method of printing following barcode is different. 2. If using CODESOFT software, firstly read the information through “Help→Index→Code128→Special input syntax”. Also refer to ASCII table. For example, if we wish to make “F1” barcode, select “code128”, then select “CODE A” type, and input “{DOC1}” as data.
