Image Capture to the Host by Host Command
This feature is only available for RS-232 and USB COM interfaces.
The host command format is as follows:
P<cnt>pSBCIF
where:
P - ASCII 'P' used as preamble of pass-through commands
<cnt> - binary value of 6 indicating 6 bytes to follow
p - ASCII lowercase 'p' ; command to take a picture
S - size value of image as ASCII character
B - brightness value in ASCII
•‘B’ == uses scanner's configuration value CI_IMAGE_BRIGHTNESS else
‘0’ thru’9’ specifies brightness
C - contrast value in ASCII
•‘C’ == uses scanner configuration value CI_IMAGE_CONTRAST else ‘0’
thru’9’ specifies contrast
I - imager selection
F - format of image
IF the image is of a type the scanner supports, capture and transmission occurs,
and the command is of proper format
THEN
The scanner will transmit an ACK (0x06) to the Host in response to this com-
mand.
The image data transmission starts with a 4 byte binary field representing (Big
Endian) number of bytes to follow.
If the “number of bytes to follow” value is zero, there was a problem with gen-
erating the image and the request should be retried.
ELSE
The scanner will transmit a BEL (0x07) to the Host in response to this com-
mand.
ENDIF
NOTE
If the USB COM interface has been selected, follow the instruc-
tions in the Interface Related Features on page 203 chapter of
this guide.
• ‘S’ == uses scanner's configuration value CI_IMAGE_SIZE
• 0’-VGA, (640X480) • 2’-FVGA, (full 1024x1280 VGA)
• ‘1’-WVGA, (752X480) •‘3’-HVGA (half vga)
• ‘V’ == vertical •‘H’ == horizontal
• ‘J == jpeg • ‘T’ == tiff
• ‘M’ == bmp (bitmap) • ‘B’ == binary
