IMAGING FEATURES
Image Capture to the Host by Host Command
This feature is only available for RS
‐
232 and USB COM interfaces.
NOTE
If the USB COM interface has been selected, follow the instructions in
USB Interface Selection on page 76
The host command format is as follows:
P<cnt>pSBC
where:
P
‐
ASCII 'P' used as preamble of pass
‐
through commands
<cnt>
‐
binary value of 4 indicating 4 bytes to follow
p
‐
ASCII lowercase 'p' ; command to take a picture
S
‐
size value of image as ASCII character
‘S’ == uses scanner's configuration value
‘0’-VGA, (640X480)
‘1’-WVGA, (752X480)
‘2’-SXGA, (1280x1027)
‘3’-CIF (320x240)
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
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
command.
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
generating 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.
