2. Interface
MT82Ag provides UART serial interface and multiple USB interfaces to
communicate with the host. Through communication interface, it is possible to
receive barcode data and send command to control MT82Ag at the same time.
2.1 UART
Scanning below configuration barcode will set MT82Ag to UART interface,
which is based on TTL level signals. For RS232 communication, a conversion
circuit must be added externally.
UART
Parameter Default
Serial communication type UART (TTL-232)
Baud Rate 9600
Parity None
Data Bits 8
Stop Bits 1
Hardware Flow Control None
2.1.1 Baud Rate

2.2.1 Intercharacter Delay
Intercharacter delay is the time interval between the release of last key and the
pressing of the next key. The configurable range is from 0 to 75ms; default is
2ms. Please refer to Appendix D for configuration method of Set
Intercharacter Delay.

2.2.2 Polling Rate
The smaller the value, the faster MT82Ag sends characters to the host. If the
host loses characters, please increase polling rate.

2.2.4 Alt Code
To ensure that all ASCII code (0x00~0xFF) can be transmitted correctly
regardless of keyboard layout, Alt Code can be enabled. When Alt Code is
enabled, transmission speed will be slower because all keyboard data is sent
by key combinations. Please select one of the following modes according to
your applications:
Mode 1: Send all ASCII code (0x20~0xFF), not supported by current keyboard
layout, by Alt Code.
Mode 2: Send all ASCII code (0x20~0xFF) by Alt Code.
Mode 3: Send all ASCII code (0x00~0xFF) by Alt Code.
Note: When Mode 3 and Control Mode are enabled at the same time, Control
Code (0x00~0x1F) will be sent by Ctrl key combinations.
Disable Alt Code* Mode 1

code depending on Control Mode status. Please refer to Appendix E for
corresponding key code for each Control Code.
Ctrl Mode Off* Ctrl Mode On
2.2.6 Capslock Mode
Letter case of all alphabets (A~Z) can be altered by below configurations.

2.3 USB VCP
When configured to USB VCP interface, MT82Ag can communicate with the
host via USB Virtual COM, which requires VCP driver to be installed.

2.4 HID POS
When configured to USB HID POS interface, MT82Ag can communicate with
the host via USB HID, which requires no driver.

3. Reading Mode
3.1 Batch Mode
In batch mode, MT82Ag starts scanning barcode when trigger pin = low. If
trigger stays low, the scanning continues, with each barcode scanned once. To
restart a new batch reading, the host must reset trigger level first and then pull
trigger low again.
Batch Mode
3.2 Trigger Mode
In trigger mode, MT82Ag starts scanning barcode when trigger pin = low. If
trigger stays low within LED timeout, the scanning continues. When trigger
level is reset or LED timeout expires, the scanning stops. To restart scanning,
the host must reset trigger level first and then pull trigger low again.
Trigger Mode
3.2.1 Trigger Condition
When trigger condition = level, the trigger pin must always stay low during a
scanning operation. When trigger condition = pulse, MT82Ag starts scanning
whenever a low level pulse at trigger pin is detected, and will continue
scanning until a barcode is scanned or a pre-set timeout is reached.
