2 - 29 data transmission stops. To resume transmission, the host sends the XON character (DC1, hex 11). Data transmission continues where it left off when XOFF was sent. Default = XON/XOFF 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. Communication Timeout This allows you to set the length (in milliseconds) for a timeout for the host ACK/NAK response. Scan the bar code below, then set the timeout (from 1-65535 milliseconds) by scanning digits from the Programming Chart, then scanning Save. Default = 2000 ms. Timeout Retries This setting limits the number of Communication Timeout retries. If the Timeout Retries is set to 0, the transmission is terminated after the ini- tial Communication Timeout. Scan the bar code below, then set the * XON/XOFF Off XON/XOFF On ACK/NAK On * ACK/NAK Off Communication Timeout
2 - 30 number of retries (from 0-255) by scanning digits from the Programming Chart, then scanning Save. (5 is the recommended set- ting.) Default = 0. Communication Timeout Beeper This selection programs the scanner to issue an error beep when a communication timeout has occurred. The error beep sound is pro- grammed using Number of Beeps – Error (page 3-4). Default = On. NAK Retries This selection limits the number of NAK retries that can occur in ACK/NAK mode. Scan the bar code below, then set the number of retries (from 0- 255) by scanning digits from the Programming Chart, then scanning Save. (5 is the recommended setting.) Default = 0, or disabled. Timeout Retries O f f * On NAK Retries
2 - 31 Support BEL/CAN in ACK/NAK This protocol responds to and commands when in ACK/ NAK mode. The scanner sounds an error tone when a command is sent from the host. terminates the transmission. Default = BEL/ CAN Off. RS232 Defaults If you want the custom RS232 default settings restored to your scanner, scan the RS232 Defaults bar code below. This resets the scanner to the custom default settings (see Setting Custom Defaults on page 1-5). If there are no custom defaults, it will reset the scanner to the factory default settings. Any settings that have not been specified through the custom defaults will be restored to the factory default settings. NCR Modifiers NCR ACK/NAK This is an NCR communication protocol for ACK/NAK processing. Default = NCR ACK/NAK Off. BEL/CAN On * BEL/CAN Off RS232 Defaults * NCR ACK/NAK Off NCR ACK/NAK On
2 - 32 Block Check Character When this selection is set to Tr a n s m i t, the NCR Block Check Character (BCC) is expected with incoming messages and transmitted with outgoing messages. Default = Transmit. NCR Prefix This selection allows you to program an NCR-specific prefix. Refer to the ASCII Conversion Chart (Code Page 1252)on page A-3 to find the hex equivalent for the characters you want for the NCR prefix (typically, 02 for STX). Scan the bar code below, then set the hex number (from 0-FF) by scanning digits from the Programming Chart, then scanning Save. Default = 0. NCR Suffix This selection allows you to program an NCR-specific suffix. Refer to the ASCII Conversion Chart (Code Page 1252)on page A-3 to find the hex equivalent for the characters you want for the NCR suffix (typically, 03 for ETX). Scan the bar code below, then set the hex number (from 0-FF) by scanning digits from the Programming Chart, then scanning Save. Default = 0. * Transmit Don’t Transmit NCR Prefix NCR Suffix
2 - 33 NCR Prefix/Suffix When set to Transmit, both the NCR prefix and suffix are transmitted with bar codes. Usually, prefixes and suffixes are programmed using the Data Editing selections (see Data Editingbeginning on page 4-1), however, the following commands override any other prefix/suffix settings. Default = Don’t Transmit. NCR NOF (Not-on-File) Error A scanner receives an NOF (Not on File) command from the POS when- ever 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 3-4) for an NOF, and disables 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 2-25, and RS232 Timeouton page 2-28 for further information. Transmit * Don’t Transmit On * Off
2 - 34 Scanner-Bioptic Packet Mode Packet Mode On must be scanned to set the scanner’s format so it is com- patible 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. Communication Timeout This allows you to set the length (in milliseconds) for a timeout for the host ACK/NAK response. Scan the bar code below, then set the timeout (from 1-65535 milliseconds) by scanning digits from the Programming Chart, then scanning Save. Default = 2000 ms. * Packet Mode Off Packet Mode On ACK/NAK On * ACK/NAK Off Communication Timeout
3 - 1 3 Input/Output Settings Power Up Beeper The scanner can be programmed to beep when it’s powered up. Scan the Off bar code(s) if you don’t want a power up beep. Default = Power Up Beeper On - Scanner. Beep on BEL Character You may wish to force the scanner to beep upon a command sent from the host. If you scan the Beep on BEL On bar code below, the scanner will beep every time a BEL character is received from the host. Default = Beep on BEL Off. Power Up Beeper Off - Scanner * Power Up Beeper On - Scanner *Beep on BEL Off Beep on BEL On
3 - 2 Good Read and Error Indicators Beeper – Good Read The beeper may be programmed On or Off in response to a good read. Turning this option off, only turns off the beeper response to a good read indication. All error and menu beeps are still audible. Default = Beeper - Good Read On. Beeper Volume – Good Read The beeper volume codes modify the volume of the beep the scanner emits on a good read. Default = High. * Beeper - Good Read On Beeper - Good Read Off * HighMedium Off Low
3 - 3 Beeper Pitch – Good Read The beeper pitch codes modify the pitch (frequency) of the beep the scan- ner emits on a good read. Default = Medium. Beeper - Transmit Order The beeper transmit order determines when the good read beep occurs. The scanner can be set to emit the good read beep either before or after data transmission. Default = Before Transmission. Beeper Pitch – Error The beeper pitch codes modify the pitch (frequency) of the sound the scan- ner emits when there is a bad read or error. Default = Razz. Low (1600 Hz) * Medium (2350 Hz) High (4200 Hz) * Before Transmission After Transmission * Razz (100 Hz) Medium (2000 Hz) High (4200 Hz)
3 - 4 Beeper Duration – Good Read The beeper duration codes modify the length of the beep the scanner emits on a good read. Default = Normal. Number of Beeps – Good Read The number of beeps of a good read can be programmed from 1 - 9. The same number of beeps will be applied to the beeper and LED in response to a good read. For example, if you program this option to have five beeps, there will be five beeps and five LED flashes in response to a good read. The beeps and LED flashes are in sync with one another. Note: The LEDs can also be programmed separately. See LED Settingson page 3-6. To change the number of beeps, scan the bar code below and then scan a digit (1-9) bar code and the Save bar code on the Programming Chart inside the back cover of this manual. Default = 1. Number of Beeps – Error The number of beeps and LED flashes emitted by the scanner for a bad read or error can be programmed from 1 - 9. For example, if you program this option to have five error beeps, there will be five error beeps and five LED flashes in response to an error. Note: The LEDs can also be programmed separately. See LED Settingson page 3-6. * Normal Beep Short Beep Short Beep Number of Good Read Beeps/LED Flashes
