4.3.12 Command 0x0C - Set Bitmap (Bitmaps Only)
This command directs the device to save new bitmap image data in the specified slot with the selected
format. The device can hold up to four different bitmaps in slots specified as Bitmap slot 1 through
Bitmap slot 4. Slot 0 holds the default bitmap image, which is generally blank and can not be changed.
For details about preparing and optimizing bitmaps for loading into the device, see
D998200065
INSTRUCTIONS FOR LOADING BITMAP IMAGES , available from MagTek.
To send new bitmap data to the device, follow these steps:
1) Issue Command 0x10 - Send Big Block Data to Device to send new bitmap image data to the
device.
2) Issue Command 0x0C - Set Bitmap (Bitmaps Only) to direct the device to save the new bitmap
image data in the specified slot with the selected format.
3) Optionally, display the Welcome page superimposed on a bitmap of the host’s choice by calling
Command 0x02 - End Session and specifying which bitmap slot to use.
To clear a bitmap from a specified slot, the host can simply issue this command with the Operation to
Perform set to 0x00 (“Clear”).
If an error occurs, the device terminates the command and reports the error in ACKSTS of
Command
0x01 - Response ACK . For a full list of error codes, see Command 0x01 - Response ACK .
