Note: Voltage level of all RS232 Pin-outs (RXD, TXD, CTS and RTS) is 0V for logic low level and 3.3V for
logic high level. A transceiver (max232) PCB is designed inside the RS232 cable, and it can achieve
signal transition between TTL and RS232.

2-4 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.
2-4-1 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 powersupply (DC 5V adapter)
to the RS-232 cable.
Figure 2-4 Installation - RS-232
2-4-2 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 2-5, 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.
Figure 2-5 Installation - USB
2-4-3 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.

2-6 Scanning
When the scanner is scanning, ensure the laser beam crosses every bar and space of the barcode. See
Figure 2-7.
2-7 Auto-detection
Note: Auto-detection and stand are optional accessories.
1. To scan a barcode, present the bar code and ensure the scan line crosses every bar and space of
the symbol.
2. Upon successful decode, the scanner beeps and the LED lights.
3. When the laser light is off, the present bar code must be removed to active next scanning.
Figure 2-8
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 2-9.
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.

3 Parameter menus
3-1 Introduction
This section describes the programmable parameters, provides barcodes for programming.
The scanner is shipped with the factory default settings as describedin this chapter. These factory-default-
settings values are stored in flash memory and are preserved even when the scanner is powered down.
Changes to the factory default values can be stored as custom defaults. These values are also stored in
flash memory and are preserved even when the scanner is powered down.
There are two methods to change the parameter values as described following.
Scan the appropriate barcodes as the example shown in 3-2 Example: configure scanner. The new
values replace the existing memory values.
Referring to 7 Return default parameters & firmware version , scan the Write to customer’s default
setting (%%WCDF) barcode to set the new values as custom defaults. The factory default or custom
default parameter values can be recalled by scanning the manufacture default setting (%%%DEF)
barcode, or the Restore customer’s default setting (%%RSDF) barcode.

12
3-2 Example: configure scanner
Note: The factory default settings are indicated with asterisks (*) in this manual.
1、Single-scan setting
Scan the appropriate Single-scan setting barcode according to the user’s demand.
Example: Set Flow control to be none.
Steps: Scan the following barcode.
2、Multiple-scan setting
The steps of configuration are:
a) Scan the SETUP barcode on the parameter setting part.
b) Enter the option mode by scanning the Parameter name barcode.
c) To the right of the option barcode, the necessary alphanumeric inputs are listed. Scan these
alphanumeric entries (see 9 Configuration alphanumeric value barcode)individually as Para.
Value.
d) Scan the END barcode, listed on the bottom of each parameter setting part.
Notes that only one parameter can be setup at each time.
Example: Set Flow control to be none.
Steps: Scan the following barcodes in order.

Figure 4-4
3-3 RS232 interface
Flow control:
None- The communication only uses TXD and RXD signals without any hardware or software
handshaking protocol.
RTS/CTS- If the scanner requests 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 Response delay

14
timeout, 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- If Decode data packet format is set to Packeted, after barcode 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.When the scanner finishes receiving the command from host, it will send ACK/NAK
to host.
Note: If Decode data packet format is set to Raw, the scanner will not wait for ACK/NAK after
transmitting decoded data completely.
Response delay: This delay is the time that the scanner waits for a handshaking acknowledgment (NAK
or ACK) from the host.
Inter-character delay: This delay is the time that the scanner transfer the each character interval. Host-
character delay: This delay is the time that the scanner waits for the host to send the next character in
serial communication.
Decoded data packet format:
Raw- Scanner sends raw decoded data directly.
Packeted- The decoded data is sent in data packet.
