(6) Note:
- Only control commands can be used to enable image transmission. There is no setting to initiate it in the QR Menu.
- During image transmission mode, scanning of barcodes or 2D codes, etc. is disabled. Further, the protocol is fixed as
Xmodem 1K.
- When setting the command parameters, use uppercase or numeric ASCII characters.
- Communications condition settings such as the command header, terminator, transmission speed, etc. are the same as those
of normal commands.
- Transmission conditions when in the Xmodem 1K Protocol are the same as during normal operation mode
(non-acknowledge mode or ACK/NAK).
- Once image transmission is completed, the transmission protocol will return to normal operation mode (non-acknowledge
mode or ACK/NAK).
- As the image is compressed during conversion to JPEG format, image quality may deteriorate.
(7) Image Transmission Time (Standard Value)
The communications adapter (BA11-RKU or BA20-RU) interface uses RS-232. Communications condition displays the
standard speed of image capture, conversion, and transmission when the protocol is Xmodem 1K and the transmission speed
is 115200 bps. As a result, transmission time will change due to the condition of Bluetooth

* As the image will undergo compression and conversion when JPEG format is selected, the file size will change
depending on the photo image (approx. 10-40KB, typically around 25 KB) The compression rate cannot be set.
