BCC Options

The BCC Option parameter permits you to enable or disable the use of BCC at the end of a message. When enabled, the BCC is the last character sent and is the Exclusive OR of each byte sent prior to the BCC, except the prefix byte. Scan the Hex 0 tag to disable the BCC Option, or scan the Hex 1 tag to enable it. The default is disable for NCR 7870-1000/3000 and enable for NCR 7870-2000/4000/4500.

Interface Control

The Interface Control parameter permits you to select how to control the transfer of data between the scanner/scale and the host terminal. The options are None, enable ACK/NAK, enable XOn/XOff, and enable both ACK/NAK and XOn/XOff.
