Chapter 1 Getting Started
Introduction
The MS842N series embedded 2D barcode scan engines are armed with CMOS image capturer, featuring fast scanning and accurate decoding on barcodes on virtually any medium - paper, magnetic card, mobile phones and LCD displays.
About This Guide
This guide provides programming instructions for the MS842N. Users can configure the MS842N by scanning the programming barcodes included in this manual.
The MS842N has been properly configured for most applications and can be put into use without further configuration. Users may check the Factory Defaults Table in Appendix for reference. Throughout the manual, programming barcodes marked with asterisks (**) are factory default values.

Barcode Scanning
The MS842N feasures fast scanning and decoding accuracy. Barcodes rotated at any angle can still be read with ease. When scanning a barcode, simply center the aiming beam or pattern projected by the MS842N over the barcode.
Programming Barcodes
Scanning the Enter Setup barcode can enable the engine to enter the setup mode. Then you can scan a number of programming barcodes to configure your engine. To exit the setup mode, scan the Exit Setup barcode.
If the engine has exit the setup mode, only some special programming barcodes, such as the Enter Setup barcode and
Restore All Factory Defaults barcode, can be read.
Enter Setup
** Exit Setup
Programming barcode data can be transmitted to the Host. Scan the appropriate barcode below to enable or disable the transmission of programming barcode data (programming commands) to the Host.

Factory Defaults
Scanning the following barcode can restore the engine to the factory defaults. See Appendix 1: Factory Defaults Table for more information.
Restoring the engine to factory defaults will not remove custom defaults stored on the engine.
Restore All Factory Defaults
Note: Use this feature with discretion.
Custom Defaults
Scanning the Restore All Custom Defaults barcode can reset all parameters to the custom defaults. Scanning the Save as Custom Defaults can set the current settings as custom defaults.
Custom defaults are stored in the non-volatile memory.

Chapter 2 Communication Interfaces
Introduction
The MS842N engine provides a TTL-232 interface and a USB interface to communicate with the host device. The host device can receive scanned data and send commands to control the engine or to access/alter the configuration information of the engine via the TTL-232 or USB interface.
Serial Communication Interface
Serial communication interface is usually used when connecting the engine to a host device (like PC, POS). However, to ensure smooth communication and accuracy of data, you need to set communication parameters (including baud rate, parity check, data bit and stop bit) to match the host device.
The serial communication interface provided by the engine is based on TTL signals. TTL-232 can be used for most application architectures. For those requiring RS-232, an external conversion circuit is needed. The conversion circuit is available only to some models.
Serial Communication
Default serial communication parameters are listed below. Make sure all parameters match the host requirements.

Hardware Flow Control
If this feature is enabled, the engine determines whether to transmit data based on CTS signal level. When CTS signal is at a low level which means the serial port’s cache memory of receiving device (such as PC) is full, the engine sends data through RS-232 port until CTS signal is set to high level by receiving device. When the engine is not ready for receiving, it will set RTS signal to low level. When sending device (such as PC) detects it, it will not send data to the engine any more to prevent data loss.
If this feature is disabled, reception/transmission of serial data will not be influenced by RTS/CTS signal.
Enable Hardware Flow Control
** Disable Hardware Flow Control
Note: Before enabling this feature, make sure that RTS/CTS signal line is contained in RS-232 cable. Without the signal
line, serial communication errors will occur.
** Exit Setup 8

USB Interface
USB-DataPipe
A driver is required when using this protocol to communicate with the engine. Its advantages include fast data transmissoin and easy to use.
USB HID-KBW
When you connect the engine to the Host via a USB connection, you can enable the USB HID-KBW feature by scanning the barcode below. Then engine’s transmission will be simulated as USB keyboard input. The Host receives keystrokes on the virtual keyboard. It works on a Plug and Play basis and no driver is required.

Beep on Unknown Character
Due to the differences in keyboard layouts, some characters contained in barcode data may be unavailable on the selected keyboard. As a result, the engine fails to transmit the unknown characters.
Scan the appropriate barcode below to enable or disable the emission of beep when an unknown character is detected.
Beep on Unknown Character
** Do Not Beep on Unknown Character
Emulate ALT+Keypad
When Emulate ALT+Keypad is turned on, any ASCII character (0x00 - 0xff) is sent over the numeric keypad no matter which keyboard type is selected. Since sending a character involves multiple keystroke emulations, this method appears less efficient.
Emulate ALT+Keypad ON
** Emulate ALT+Keypad OFF
Function Key Mapping
When Function Key Mapping is enabled, function character (0x00 - 0x1F) are sent as ASCII sequences over the numeric
keypad. For more information, see Appendix 6: ASCII Function Key Mapping Table
A shortcut to send a function key (F1-F12) is to scan the corresponding barcode in Appendix 9: F-Key Barcodes.
.
Note: Emulate ALT+Keypad ON prevails over Enable Function Key Mapping.

Caps Lock
The Caps Lock ON option can invert upper and lower case characters contained in barcode data. This inversion occurs regardless of the state of Caps Lock key on the Host’s keyboard.
Caps Lock ON
** Caps Lock OFF
Note: Emulate ALT+Keypad ON/ Convert All to Upper Case/ Convert All to Lower Case prevails over Caps Lock ON.
Example: When the Caps Lock ON is selected, barcode data “AbC” is transmitted as “aBc”.
** Exit Setup 12
Convert Case
Scan the appropriate barcode below to convert all bar code data to your desired case.
** No Case Conversion
Enter Setup
Convert All to Upper Case
Convert All to Lower Case
Example: When the Convert All to Lower Case feature is enabled, barcode data “AbC” is transmitted as “abc”.
Emulate Numeric Keypad
When this feature is disabled, sending barcode data is emulated as keystroke(s) on main keyboard.
To enable this feature, scan the Emulate Numeric Keypad barcode. Sending a number (0-9) is emulated as keystroke(s) on numeric keypad, whereas sending other character like “+”, “_”, “*” , “/” and “.” is still emulated as keystrokes on main keyboard.
Numeric keypad is usually situated at the right of the main keyboard. The state of Num Lock on the simulated numeric keypad is determined by its equivalent on the Host. If Num Lock on the Host is turned off, the output of simulated numeric keypad is function key instead of number.
Emulate Numeric Keypad
** Do Not Emulate Numeric Keypad
Note: Make sure the Num Lock light of the Host is turned ON before enabling this feature.
Simulate ALT+Keypad ON prevails over Emulate Numeric Keypad.
13 **Exit Setup
Enter Setup
Example: Supposing the Emulate Numeric Keypad feature is enabled:
if Num Lock on the Host is ON, “A4.5” is transmitted as “A4.5”;
if Num Lock on the Host is OFF, “A4.5” is transmitted as follows:
1. “A” is sent as is because it is not included in numeric keypad;
2. “4” is sent as the function key “Cursor Move to Left”;
3. “.” is sent as the function key “Delete After the Cursor”;
4. “5” is not sent as it does not correspond to any function key.
USB COM Port Emulation
If you connect the engine to the Host via a USB connection, the USB COM Port Emulation feature allows the Host to receive data in the way as a serial port does. However, you need to set communication parameters on the engine to match the Host requirements.
USB COM Port Emulation
HID-POS
The HID-POS interface is recommended for new application programs. It can send up to 56 characters in a single USB report and appears more efficient than keyboard emulation.
Features:
HID based, no custom driver required.
Way more efficient in communication than keyboard emulation and traditional RS-232 interface.
Note: HID-POS does not require a custom driver. However, a HID interface on Windows 98 does. All HID interfaces employ standard driver provided by the operating system. Use defaults when installing the driver.
HID-POS
** Exit Setup 14
Access the engine with your program:
1. Use CreateFile to access the engine as a HID device.
2. Use ReadFile to deliver the scanned data to the application program.
3. Use WriteFile to send data to the engine.
Enter Setup

Chapter 3 Scan Mode
Trigger Mode
If the Trigger Mode is enabled, receiving a valid trigger signal activates a decode session. The session continues until the barcode is decoded as long as the trigger signal remains valid; the session stops when the signal becomes invalid. For good decode, the engine transmits decoded data via communication port. To activate another session, the Host first terminates the trigger signal, waits 20ms or longer and then makes the signal valid.
Trigger Mode
Auto Mode
If the Auto Mode is enabled, the engine activates a decode session every time it detects a change in ambient illumination. The decode session continues until the barcode is decoded or the Decode Session Timeout occurs.
Receiving a trigger signal can also activate a decode session. The decode session continues until the trigger signal becomes invalid or the barcode is decoded or the Decode Session Timeout occurs. The trigger signal needs to be terminated before the engine is able to monitor ambient illumination again.

This parameter sets the maximum time decode session continues during a scan attempt in the Auto Mode. It is programmable in 1ms increments from 500ms to 3600000ms. The default timeout is 3000ms. To learn how to program this
parameter, see the “a. Program the Decode Session Timeout” section in Appendix.
Decode Session Timeout
Timeout Between Decodes (Same Barcode)
In order not to decode a barcode repeatedly, you can program this parameter to prevent the engine from rereading the same barcode in a given period of time.
This parameter sets the timeout between decodes for the same barcode in the Auto Mode. It is programmable in 1ms increments from 1ms to 3600000ms. The default timeout is 1500ms.
To learn how to program this parameter, see the “b. Program the Timeout between Decodes (Same Barcode)” section in Appendix.
Timeout Between Decodes (Same Barcode)
Disable Timeout Between Decodes: Allow the engine to re-read the same barcode.
Enable Timeout Between Decodes: Do not allow the engine to re-read the same barcode before the Timeout Between Decodes (Same Barcode) occurs.

Continuous Mode
Enter Setup
This mode enables the engine to scan/capture, decode and transmit over and over again.
If the Continuous Mode is enabled, the engine activates/suspends/resumes barcode reading through control over the trigger signal. When barcode reading is in progress, terminating the trigger signal after having kept it valid for 30ms or longer will suspend barcode reading; when barcode reading is suspended, performing the same control over the trigger signal will resume barcode reading.
Continuous Mode
Timeout Between Decodes (Same Barcode)
In order not to decode a barcode repeatedly, you can program this parameter to prevent the engine from rereading the same barcode in a given period of time.
This parameter sets the timeout between decodes for the same barcode in the Continuous Mode. It is programmable in 1ms increments from 1ms to 3600000ms. The default timeout is 1500ms.
To learn how to program this parameter, see the “b. Program the Timeout between Decodes (Same Barcode)” section in Appendix.
Disable Timeout Between Decodes: Allow the engine to re-read the same barcode.
Enable Timeout Between Decodes: Do not allow the engine to re-read the same barcode before the Timeout Between
Decodes (Same Barcode) occurs.

Chapter 4 Scanning Preferences
Introduction
This chapter contains information as to how to adapt your engine to various applications with preference setting. For instance, to improve barcode reading performance off mobile phones and LCD displays; or to narrow the field of view of the engine to make sure it reads only those barcodes intended by the user.
Regular Mode/Mobile Phone Mode
The engine can capture barcodes printed on paper labels or displayed on the screen of a mobile phone. Select a mode as per actual need.
Regular Mode: Read barcodes printed on paper or plastic.
Mobile Phone Mode: Read barcodes off mobile phones or LCD displays.

Decode Area
Whole Area Decoding
When this option is enabled, the engine attempts to decode barcode(s) within its field of view, from the center to the periphery, and transmits the barcode that has been first decoded.

Central Area Decoding
The engine attempts to decode barcode(s) within a specified central area and transmits the barcode that has been first decoded. This option allows the engine to narrow its field of view to make sure it reads only those barcodes intended by the user. For instance, if multiple barcodes are placed closely together, central area decoding in conjunction with appropriate pre-defined central area will insure that only the desired barcode is read.
Central Area Decoding
Specify Central Area
The default central area is a (Width*20%) by (Height*20%) area in the center of the engine’s field of view, as shown in the
figure below. You can define the central area by scanning the Specify Central Area barcode and numeric barcode(s) corresponding to a desired percentage (1-100). If Central Area Decoding is enabled by scanning the Central Area Decoding barcode, the engine only reads barcodes that intersect the predefined central area.
To learn how to program this parameter, see the “c. Program the Central Area” section in Appendix.
