(5) Image capturing operation
1) Upon receipt of an IMAGEOUT command, the scanner captures an image, beeps three times, and switches to the
image transmission mode (Xmodem 1K protocol).
2) When the thumbnail is enabled:
The scanner transmits a thumbnail (BMP file in 1/64 VGA) repeatedly.
Pressing the trigger switch causes the scanner to beep once, capture an image, and start transmission (Xmodem 1K
protocol).
When the thumbnail is disabled:
The scanner immediately captures an image and transmits it in the format specified by IMAGEOUT parameters
(Xmodem 1K protocol).
3) Upon completion of transmission, the scanner beeps once and exits the image transmission mode.
(6) Notes
 Image transmission can only be command-controlled; it cannot be started by the QR-coded parameter menu.
 When the scanner is in the image transmission mode, it cannot scan bar codes or 2D codes. The protocol is fixed to
the Xmodem 1K.
 Parameters of the IMAGEOUT command should be uppercase or numerical ASCII characters.
 Transmission condition settings such as header, terminator and transmission speed for the image transmission are
the same as those for ordinary commands.
 Upon completion of image transmission, the scanner returns to the normal communications protocol
(non-acknowledge mode or ACK/NAK mode).
 In a JPEG file format, images are compression-converted, so the image quality may be lower.
(7) Image transmission time required (Typical)
The table below lists the typical image transmission time required from image capturing to conversion and
transmission under the following conditions:
Communications adapter BA10-RKU using the RS-232C interface
Communications protocol: Xmodem 1K
Transmission speed: 115200 bps
However, this may vary according to the Bluetooth
Video mode
Standard VGA
1/4 VGA
1/16 VGA
Thumbnail (1/64 VGA)
Standard VGA
* In a JPEG file format, images will be compression-converted, so the file size may vary, depending on images
scanned (approx. 10 to 40 KB, normally 25 KB). No compression ratio can be specified.
