DIRECT COMMANDS FROM HOST

ON DEMAND TRANSFER ARRAY IMAGE COMMAND

All the images stored in the Transfer Array Image Buffer can be sent over the dedicated

Transfer Image FTP Client if requested by the Host (On Demand). To do this the Host must

send the following command string over the Ethernet Data Socket channel:

<ESC> [ T I <node> (hex values 1B 5B 54 49 xx)

Where <node> (xx) = reader node address:

0 (hex 00) = download images from Master

1 to 31 (hex 01 to 1F) = download images from Slave xx

255 (hex FF) = download images from entire array

The Matrix reader does not reply to this command.

ROTATE LAST IMAGE COMMAND

DESCRIPTION HOST COMMAND REPLY MESSAGE

1 Rotate Last Image <ESC> <ACK>

After sending this command the reader activates the Code Rotation on the last

image present in the Image Buffer. It uses the Code rotation info in order to obtain a

Code orientation equal to 0 degrees. This command is meaningful only when a code

is present in the last image of the Image Buffer.

If the command is correct, the device confirms with the first reply message. If

programming command is wrong (i.e. no image present in the Image Buffer) or due

to a transmission error, Matrix replies with the second error message.

DECODE LAST IMAGE COMMAND

DESCRIPTION HOST COMMAND REPLY MESSAGE

1 Decode Last Image <ESC> <BEL>

After sending this command the reader Decodes any barcode present in the last

image of the Image Buffer.

If the command is correct, the device confirms with the first reply message. If

programming command is wrong (i.e. no image present in the Image Buffer) or due

to a transmission error, Matrix replies with the second error message.
