NCR NOF (Not-on-File) Error
A scanner receives an NOF (Not on File) command from the POS whenever it cannot cross-reference the bar code to a
price parameter. When set to On, the error tone sounds (set via Number of Beeps – Error, page 4-3) for an NOF, and dis-
ables the scanner while the cashier looks up the price manually. When set to Off, no sound is emitted for an NOF. Default
= Off.
Scanner to Bioptic Communication
The following settings are used to set up communication between Honeywell scanners and bioptic scanners.
Note: The scanner’s baud rate must be set to 38400 and the RS232 Timeout must be set to 3000 in order to communicate with
a bioptic scanner. See "RS232 Modifiers" on page 2-22, and RS232 Timeout on page 2-25 for further information.
Scanner-Bioptic Packet Mode
Packet Mode On must be scanned to set the scanner’s format so it is compatible with a bioptic scanner. Default = Packet
Mode Off.
ACK/NAK
After transmitting data, the scanner waits for an ACK character (hex 06) or a NAK character (hex 15) response from the
host. If ACK is received, the communications cycle is completed and the scanner looks for more bar codes. If NAK is
received, the last set of bar code data is retransmitted and the scanner waits for ACK/NAK again. Turn on the ACK/NAK
protocol by scanning the ACK/NAK On bar code below. To turn off the protocol, scan ACK/NAK Off. Default = ACK/NAK
Off.
