2. Communication Connection
MJ104 reader module provides TTL-232 serial communication interface and USB interface (optional
function) to communicate with the host. Through the communication interface, the reading data can
be received.
2.1 Communication Mode Selection
The factory defaults to use USB-HID mode for communication. Users can switch between the
communication port output modes (TTL-232 serial port mode/virtual serial port/USB-HID mode)
through scan code settings. When users need USB and serial port to output at the same time, they
can select HID & TTL simultaneous output mode by reading the setting code. When the user switches
the communication mode, he needs to wait for the device initialization to complete before
performing related operations.
Note: When the module is set as a USB virtual serial port and communicates with the host through
this port, the host needs to install the corresponding driver.
1. Communication Port Output Mode
Read the following setting codes to set the communication output mode.
TTL-232 Serial Mode
**USB-HID Mode
USB Virtual Serial Mode USB Virtual Serial Mode
2.2 Serial Communication Interfaces
The serial communication interface is a common way to connect the reading module and the host
device. When using the serial communication interface, the communication parameter configuration
must be completely matched between the reading module and the host device to ensure smooth
communication and correct content.
The serial communication interface provided by the reading module is a TTL level signal. The TTL-232
format can be connected to most application architectures, but when the RS-232 format must be
used, a conversion circuit needs to be added externally.

3.1 Manual Mode
Manual mode is the default reading mode. In manual mode, press the trigger button, and the reading
module will start shooting and reading; within the limited time range of "single reading time", if the
reading is successful, the reading module will output the reading content through the communication
interface and stop reading, if you need to start a new reading, you need to trigger the button again.
If the reading exceeds the single reading time, the shooting and reading will be suspended.
**Manual Mode
1. Trigger Mode
The trigger condition can be selected in manual mode. The default trigger condition is level trigger,
or edge trigger can also be selected.
•Edge triggering means that the level pulse of the trigger signal is detected, that is, the reading
starts, and the reading ends when the reading is successful or the single reading time condition
is reached
•The level trigger condition means that the level of the trigger signal needs to be maintained
from the beginning of the reading to the end of the reading. When the trigger level is cancelled,
the reading is successful or the reading exceeds the single reading time, the reading ends.
Edge triggering ** level trigger condition
2. Single reading time

3.4 Induction mode
The induction mode refers to a working mode in which the reading module enters the reading by
sensing the changes in the brightness of the surrounding environment. When the scene changes, the
reading module starts to read. After the reading is successful and the output information or the single
reading time expires, the reading module needs a certain interval (settable) to re-enter the
monitoring state. If the following conditions do not occur, the reading module will work in cycles as
described above: if the barcode is not scanned within a single reading time, the reading module will
automatically suspend the reading and enter the monitoring state. In the induction reading mode,
the reading module can also start to read the code after pressing the trigger button and continue to
monitor the brightness of the surrounding environment when the code is successfully output or the
trigger button is released.

output methods for control characters smaller than 0 x 20, and the user can switch by scanning the
following setting codes.
** Ctrl mode
Alt mode
2. Control character transmission
The ASCII characters located between 0 x 00 ~ 0 x 1F can be escaped into a certain control function
key. When the virtual keyboard is enabled (other HID Keyboard related settings of the module are
default values), the input operation of the control function keys is as follows: (For the specific ASCII
value and the corresponding relationship between the control function keys, please refer to the
control character correspondence table).
(1) The virtual keyboard Ctrl mode is turned on
•The read data is "A <HT>F (HT is an invisible character, not displayed on the terminal
software)" (the hexadecimal value is 0x41/0x09/0x46), the operation of the virtual keyboard
of the scan module is as follows:

18
•Input "A"-press button A
•Enter "Ctrl I" - Since the data of 0 x 09 corresponds to the control function key "I", the virtual
keyboard will hold down Ctrl, then press the I key, and finally release the Ctrl and I keys at the
same time
•Enter "F"-press button F
•Since "Ctrl I" corresponds to the function of converting characters into italics in some word
processing software, you may see normal characters "A" and italic "F" after completing the
above operations
•Currently, in the QL1601 small module, the virtual keyboard Ctrl mode "control character
output only supports the US keyboard layout
(2) Virtual keyboard Alt mode
•If the virtual keyboard is turned on and set to "Alt mode", the corresponding control
character output operation is: ALT+ "character corresponds to ASCII code decimal value". For
example, for "<HT>" characters, the virtual keyboard operation of the scanning module is as
follows:
•Enter "Alt 0 9"-the virtual keyboard will hold down Alt, then press "0" and "9" on the numeric
keypad in turn, and finally release Alt
•When the standard keyboard is output, the control character output function is closed, and
the ASCII characters smaller than 0x20 will output the corresponding key value function (For
corresponding functions, please refer to the control character correspondence table)
