1 Getting Started
1.1 Introducing the MS846
This guide provides programming instructions for the MS846 . Users can configure the MS846 by scanning
the programming barcodes included in this manual.
The MS846 features 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 MS846
over the barcode.
1.2 Factory Defaults
Scanning the following barcode can restore the engine to the factory defaults.
Note: Use this feature with discretion.
Restore All Factory Defaults

2 Communication Interfaces
The MS846 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.
2.1 TTL-232 Cable Select
Before using Serial Communication interface, scanner must be set as TTL-232 cable. Please reset the
scanner after set 232-cable.
232 Cable
Reset

2.2 TTL-232 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-level 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.
Default serial communication parameters are listed below. Make sure all parameters match the host
requirements.

requirements.

2.5 USB HID-KB
When you connect the engine to the Host via a USB connection, you can enable the USB HID-KB 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.

2.7 Convert Case
Scan the appropriate barcode below to convert barcode data to your desired case.
No Case Conversion (default)
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”.
2.8 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. A driver is required for this feature.
USB COM Port Emulation

3 General Configuration
3.1 Trigger Mode
If the Trigger Mode is enabled, you could activate the scanner by providing an external hardware trigger, or
using a serial trigger command. When in manual trigger mode, the scanner scans until a barcode is read, or
until the hardware trigger is released. When in serial mode, the scanner scans until a barcode has been read
or until the deactivate command is sent.
Trigger Mode(default)
3.2 Continue Mode
This set the scanner to work in Continue mode.
Continue Mode

3.3 Cellphone Mode
If the Cellphone Mode is enabled, the engine activates a special capturing image and illumination session.
Every 3 frame open one illumination.
When the backlight of cellphone is weak and the reflection is strong, please scan mode 1
Cellphone Mode 1
When the backlight of cellphone is not weak and the reflection is strong, please scan mode 2

To set a customer prefix, scan the “Set Custom Prefix” barcode and the numeric barcodes which representing
the hexadecimal values of a desired prefix, and then scan the “Save” barcode. Refer to Appendix 2: ASCII
Table for hexadecimal values of characters.
Example: Set the custom Prefix to “ODE”
1. Check the hex values of “ODE” in the ASCII Table. (“ODE”: 4F, 44, 45)
2. Scan the Set Custom Prefix barcode.
3. Scan the numeric barcodes”9”,”9”, “4”, “F”, “4”, “4”, “4” and “5”in Appendix 5 .
4. Scan the Save barcode.
