1.5 Custom Default
You can create your own custom default. Scan Save Custom Default
configuration barcode below and all the current settings of MT84G will be
saved to your custom default, overwriting, if any, the previous one. Scan
Custom Default to reset MT84G to the custom default settings.
Save Custom Default Custom Default
1.6 Check Version
To check firmware version, please scan below configuration barcode.

1.7 Write/Read Device ID
User can write or read Device ID of up to 16 bytes of alphanumeric via UART
or USB VCP interface.
To write Device ID:

MT84G User’s Manual V0.1
___________________________________________________________________________________
13
Host sends: WriteDeviceID:(desired Device ID).
Device responds: same as write command
To read Device ID:
Host sends: ReadDeviceID
Device responds: DeviceID:(current Device ID)
Example: to write/read Device ID:MT84G001
To write Device ID:
Host sends: WriteDeviceID:MT84G001.
Device responds: WriteDeviceID:MT84G001.
To read Device ID:
Host sends: ReadDeviceID
Device responds: DeviceID:MT84G001
Note:
1. Write command is followed by comma ( . ) as ending symbol.
2. When no Device ID is defined, device will respond with “DeviceID: NULL”
when read.
3. No response indicates write command error (wrong format or data).
Check Device ID

2. Interface
2.1 Introduction
MT84G provides UART serial interface and multiple USB interfaces to
communicate with the host. As a result it is possible to establish bi-directional
communication which enables barcode data receiving and command sending
between MT84G and host at the same time.
2.2 Interface Options
By default interface is USB HID. Scanning below configuration barcode will
switch MT84G among different interfaces (UART/USB VCP/USB HID). When
USB and UART are simultaneously needed, please select HID & UART. After
switching interface, please wait for initialization to finish before operation.
UART USB HID*
USB VCP HID & UART
2.2 UART
The UART communication of MT84G is based on TTL level signals. For RS232
communication, a conversion circuit must be added externally.
Parameter Default
Serial communication type UART (TTL-232)

2.3.8 Virtual Keyboard
To adapt to more regional applications, virtual keyboard can be enabled at the
cost of data output speed. Please make sure all alphabet keys and number
keys are available when using virtual keyboard.

Standard Keyboard* Virtual Keyboard
1. Control Code Output Methods
Control code (0x00 ~ 0x1F) can be sent by two methods:
Ctrl Mode* Alt Mode
2. Control Code Output
The ASCII between 0x00 to 0x1F can be transformed into control code.
When virtual keyboard is enabled, the output sequence of control code is
as follows:
(1) Ctrl Mode:
A barcode of “A<HT>F” (0x41/0x09/0x46) is scanned, the output
sequence of virtual keyboard is:
a. Enter “A” – Press A key
b. Enter “Ctrl + I” – Since 0x09 corresponds to “CtrI + I”, virtual keyboard
will press and hold Ctrl key, press I key, and release Ctrl key and I key
c. Enter “F” – Press F key
Since “Ctrl+I” is shortcut for italicizing text in some software applications,
the result of above output sequence can be a regular A plus an italic F.
Please note that Ctrl Mode is only supported by English (USA) keyboard
layout.
(2) Alt Mode:
When virtual keyboard and alt mode are enabled at the same time, the
control code output will be ALT + ASCII Decimal Value. For <HT>, the
output sequence of virtual keyboard is:
