To read Device ID:
Host sends: ReadDeviceID.
Device responds: SN:xxxx;MID:xxxx;FID:xxxx.
Example: to write/read Device ID: SN:20230120;MID:MT89M;FID:MARSON.
To write Device ID:
Host sends: WriteDeviceID:SN:20230120;MID:MT89M;FID:MARSON.
Device responds: WriteDeviceID:SN:20230120;MID:MT89M;FID:MARSON.
To read Device ID:
Host sends: ReadDeviceID.
Device responds: SN:20230120;MID:MT89M;FID:MARSON.
Note:
1. Write command is followed by comma ( . ) as ending symbol.
2. When no Device ID is defined, device will respond with
“SN:NULL;MID:NULL;FID:NULL.” when read.
3. No response or “FALSE” as response indicates write command error
(wrong format or data).

2. Interface
2.1 Introduction
MT89M 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 MT89M and host at the same time.
2.2 Interface Options
By default interface is USB HID. Scanning below configuration barcode will
switch MT89M 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
VID&PID can be used to locate MT89M by the host. Below are the
corresponding VID&PID among various USB interfaces.

2.2 UART
The UART communication of MT89M is based on TTL level signals. For
RS232 communication, a conversion circuit must be added externally.
Parameter Default
Serial communication type UART (TTL-232)
Baud Rate 9600
Parity None
Data Bits 8
Stop Bits 1
Hardware Flow Control None
2.2.1 Baud Rate
The unit of Baud Rate is bps (bits per second); below are available options:

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.

1. Control Code Output Methods
Control code (0x00 ~ 0x1F) can be sent by two methods:
Ctrl Mode Alt Mode
Disable Output*
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:
Enter “Alt + 0 + 9” – Virtual keyboard will press and hold Alt key, press “0”
and “9” on numeric keypad respectively, and release Alt key.
When in standard keyboard, control code (0x00 ~ 0x1F) will be sent
according to its function key definition, as seen in below table:
