A776-PG00001 C 12/09 A776 (B780) Programming Guide
Congure/Change Image Transmission Port
Hexadecimal: 1D B1 m n
Parameters: m = 0 (default) after scanning, status + image le goes to the port issuing the scan or transmit function; =
1 all image transmissions go only to a 2nd channel Ethernet port. N = 0 indicate that this conguration is temporary (till
powered o, default, or n = 1 selection is also retained in non-volatile memory.
Return: None
Description: This command species whether or not all image transmissions should only use a 2nd high-speed
imaging channel. The physical port for this channel must be the Ethernet port. Irrespective of which of the two
command streams issued an image transmission action, when M = 1 the #2 port will be used to transfer all image
les. The N parameter indicates whether the choice is to be treated as a permanent setting at power-on time, or just a
resetting of whatever the permanent setting was.
When MICR is congured to uses the top path head, a legacy MICR read command will not result in an image capture.
But an image scan using the slip entry point will implicitly read MICR which will be placed in the imager buer and will
be available in the TIFF header of the next image transmission.
Set Top Entry Startup Delay
Hexadecimal: 1D B2 n
Parameters: n is interpreted the same as in the second parameter in the set slip waiting time command (1B 66 m n),
i.e. the delay between front image sensor detect and motor start for movement along the path expressed in tenths
of a second, with 9 (default) indicating 900 ms; maximum value is 50 (5 seconds) waiting. There is similar to the clamp
action in the slip, except that document movement starts immediately after this delay. This command is ignored if the
value of n is greater than 50.
Return: None
Description: This command sets the delay between detecting the presence of a document at the front sensor and
starting the path rollers to scan the document. Note: If a document is being sent from the slip station to the imager
(back sensor), that timing delay is automatically determined.
Set Image Format Properties
Hexadecimal: 1D B3 m p r
Parameters: m species if the image captured should be rotated 90 degrees to have the width size be the largest value
(0 = no change from previous setting; 1= no, default, 2 = yes). The rotation direction is such that documents inserted
(at either opening) face up with the bottom edge on the right will be right side up. p species the image transmit
format selection (default value = 7) as follows:
Value Denition
0 No change from previous setting
1 LZW (lossless, also used in GIF) compressed grayscale (in TIFF Wrapper)
2 CCITT T.6 compression (G4 binary) (in TIFF Wrapper)
3 Reserved for JPEG (lossy) (in TIFF Wrapper) (Future)
4 Binarized, no compression (in TIFF Wrapper)
6 16 level (4 bit) packed bytes format (1/2 size of raw, ignores R parameter drop bits) (in TIFF Wrapper)
7 No compression, raw (256 level) grayscale (in TIFF Wrapper), default
