Configure/Change Image Transmission Port

Hexadecimal: 1D B1 m n

Parameters: m = 0 (default) after scanning, status + image file 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 configuration is temporary (till powered off, default, or n = 1 selection is also retained in non-volatile memory.

Return: None

Description: This command specifies 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 files. 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 configured 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 buffer 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 specifies 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 specifies the image transmit format selection (default value = 7) as follows:

Value	Definition
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
