• If the scanner cannot communicate with the communication unit wirelessly, then the

barcode will not be read. (A low-pitched beep will sound twice.)

• Be sure to aim the laser to scan the entire length of the barcode.

{ Correct Scan XIncorrect Scan

2

• Only shine the laser light on one barcode at a time. Scanning multiple barcodes at once

can lead to scan errors, or barcodes being scanned out of order.

X Incorrect Scan

• Depending on the laser reflection, interior lighting, or barcode label angle, light reflected

from the label may be partially reflected, resulting in scan errors.
In such situations, adjust the label and laser angle or distance.

• When scanning an RSS Stacked barcode, aim the laser and scan from the top of the

barcode to the bottom, or from the bottom to the top.

z Caution when using the BL-N9UB/N9V

When using the BL-N9UB/N9V, barcode data read by the BL-N90 is treated as data
entered through the keyboard. In this way, data may be input directly into the running
application, without the need for special drivers.

When using the BL-N9UB/N9V, please note the following:

• Do not try to read a barcode while pressing down a key on the computer's keyboard. Do

not press a key while receiving the data. Data input will not be read correctly.

• If the computer has multiple language settings, make sure that the input mode is set for

half-width alphanumeric characters.

Inter-character Delay

The time between each character can be set to three levels for the data sent from the BL-N90
series to the computer ( page 4-22).

If the processing speed on the computer is slow, set a longer value for the inter-character
delay. If the delay is not set long enough, the computer processing speed may fall behind
and digits may be dropped from the data. Adjust the inter-character delay so that data is
received correctly from the reader.

RS-232C Communication Interface (BL-N9R)

The RS-232C communication protocol can be set to no protocol, RTS/CTS, or ACK/NAK
( page 4-24).

z No protocol

There is no procedure used for communication Once the barcode is read, the data is sent
in sequence.

z RTS/CTS

The CTS signal for RS-232C (RTS on the host side) can wait to send data by using the
following methods.

• CTS signal off (Low) : Waits to send data.

• CTS signal on (High) : Sends data.

Barcodes cannot be read while waiting to send data.

RTS signal for RS-232C

Note

• With "No protocol," the RTS signal is normally set to "Always on (High)".

• With "RTS/CTS," the RTS signal becomes "On only when sending data (High)."

z ACK/NAK

The reader sends data between the host by using the following procedure.

1 Read data is sent to the host from BL-N9R.

BL-N9R waits for a response from the host (ACK [06h]: Completed without errors, NAK
[15h]: Request resend). While waiting for ACK [06h], the next barcode cannot be read.

2 The response is sent from the host to BL-N9R.

When the ACK [06h] response is sent, the first communication is completed.

•

BL-N9R can send the following read data (it does not respond with ACK [06h]).

•

When the NAK [15h] response is sent, BL-N9R resends the same data and waits for the
ACK [06h] response.

3-5 Charge Error Prevention

Charging terminals

To computer

BL-N90 includes a feature to warn users about charge errors.

z Charge error prevention

This function sounds an alarm if the BL-N90 is set in the communication unit and fails to
charge correctly.
The function is turned off in the initial setting (factory default).

The following situations may cause the scanner to charge incorrectly.

• The charging terminals for the BL-N90 and the communication unit are not touching.

→ Reset the BL-N90 so that the charging terminals touch correctly.

• The charging terminals are dirty.

→ For details about cleaning the charging terminals, see "Maintenance" on page 8.

Descriptions of Key Functions

z Using charge error prevention

To use this detection function, switch the "Charge error prevention function" setting on the
BL-N90 to "On."
For information about setting this function, see page 4-25.

3-13

3-6 Sleep Mode

Set the BL-N90 to sleep mode in the following situations.

• When not using the BL-N90 for a long period of time

Since the BL-N90 and the communication unit are continuously communicating wirelessly,
battery power is depleted even when the scanner is not reading a barcode. Enabling
sleep mode interrupts the wireless communication to the communication unit, thereby
saving battery power.
For details on power consumption, see page 2-12.

• When changing the BL-N90 pairing (when using multiple BL-N90 and communication

units)
When changing the BL-N90 pairing, set the BL-N90 that is currently being used to sleep
mode.

Descriptions of Key Functions

For details about changing the pairing, see page 2-14.

z Setting sleep mode

Press and hold "Trigger" for about 10 seconds.
After setting sleep mode, the following actions occur.

• The buzzer sounds once long beep.

• The blue LED on the communication unit lights up (wireless communication stopped).

z Releasing sleep mode

To release the sleep mode, press "Trigger".

• Wait 10 to 30 seconds until wireless communication starts.

• Once wireless communication starts, the blue LED on the communication unit lights up.
