Retrieve next image location
EIA-232 syntax:
GS N SOH NULL or X'1D 4E 01 00'
Remarks:
Returns the table position where the next image is stored. Command is
Extend MCT Request command (2-byte address). Status byte 5, bit 3 is set
to indicate data is attached.
Retrieve first unread image location
EIA-232 syntax:
GS N SOH SOH or X'1D 4E 01 01'
Remarks:
Stored images are searched sequentially, and the first location that has not
been set to ″read″is returned. The command is Extend MCT Request
(2-byte address). Status byte 5, bit 3 is set to indicate data is attached.
Select compression format and scanned image threshold
EIA-232 syntax:
X'1B;4d;x;n1;n2'
where:
vx = X'1F'
– address to store data
vn1
– 00 200 DPI TIFF-CCITT-Group 4 compression
– 01 200 DPI JPEG compression
– 02 200 DPI BMP (uncompressed)
– 04 200 DPI TIFF file, no compression (gray scale)
– 10 100 DPI TIFF-CCITT compression (black and white)
– 11 100 DPI JPEG compression (gray scale)
– 12 100 DPI BMP (uncompressed gray scale)
– 14 100 DPI TIFF File (no compression)
vn2
– Lightens or darkens the contrast of a scanned image. Higher numbers
print darker.
Remarks:
The current format applies to retrieval and storage of the currently scanned
image. Changing the format does not change the format of any images
already stored in flash. The setting is persistent across reset and power
cycles.
