The MT40 Linear Image Barcode Scan Engine is designed for 1D high performance
barcode scanning with optimal performance and easy integration. MT40 is ideal for
integration into data terminals and other small mobile devices. Wide-angle version
(MT40W) is also available.
The MT40 consists of 2 illumination LEDs, a high-quality linear image sensor and a
microprocessor that contains powerful firmware to control all aspects of operations
and enable communication with the host system over the standard set of
communication interfaces.
Two interfaces, UART & USB, are available. UART interface communicates with the
host system over TTL-level RS232 communication; USB interface emulates a USB
Keyboard device and communicates with the host system over USB.

Once trigger is pressed (pull low), scanning
operation continues until a barcode is

lly decoded or the trigger is released
(pull high). To proceed to the next scanning
operation, release (pull high) first and press (pull
low) the trigger again.

This chapter describes the timing associated with the various operating modes of
the MT40 including Power Up, Sleep Mode, and Decode Timing.

1- -3 3- -1 1. . P Po ow we er r U Up p
When power is initially applied, the MT40 is activated and begins the
process of initialization. Once initialization (duration ≦10mS) is
completed, the MT40 enters Standby Mode and is ready for barcode
scanning.

1- -3 3- -2 2. . S Sl le ee ep p M Mo od de e
The MT40 may enter Sleep Mode after a programmable time period has
elapsed without any activity. Please see Chapter 6 for more details about
Sleep Mode.
1
1- -3 3- -3 3. . D De ec co od de e T Ti im mi in ng g
In Standby Mode, the MT40 is activated by the Trigger signal which MUST
be kept low for at least 20 ms until the successful scan is achieved, as
indicated by the Buzzer/LED signals.
In Sleep Mode, the MT40 can be waken up by the Trigger signal which
MUST be kept low for at least 2 mS, which will prompt the scan engine into
Standby Mode.
The total scan and decode time is approximately equal to the time from the
Trigger signal going low to the Buzzer/LED signal going high. This time will
vary slightly based on several factors including barcode quality, barcode
type and the distance between MT40 and the barcode scanned.
Upon a successful scan, the MT40 outputs the Buzzer/LED signal and
keeps this signal for the duration of the transmission of the data decoded to
the host side. The duration is about 75 ms.
Therefore, the total duration of a typical scanning operation (from Trigger
turning low to the end of Buzzer PWM signal) is also approximately 120mS.

1. The maximum duration of initialization is 10mS.
2. The maximum duration of scanning operation in Standby Mode is 120mS.
3. The minimum duration of waking up MT40 from Sleep Mode by
Trigger signal is about 2 ms.
4. The maximum duration of waking up MT40 from Sleep Mode by Trigger
signal and completing decode (when barcode is within optimal focus) is
about 120ms
