4.3. Display LEDs and Beeper Control

A notification given to inform the operator that barcode reading has been performed successfully can be

controlled as follows. This is specified at the Scanner.RdMode property.

• Turn ON/do not turn ON display LEDs. (Default: Turn ON display LEDs.)

• Sound/do not sound beeper. (Default: Sound beeper.)

If set to “Turn ON display LEDs.”, it will not be not possible to control the LEDs from the application while

barcode reading is enabled.

If set to “Do not turn ON display LEDs.”, the LEDs can be controlled from the application, even while barcode

reading is enabled. As a result, actions such as the following are possible.

• The read barcode value is checked at the user program, and the blue LED is turned ON only when the

barcode is read correctly.

• The red LED is turned ON when a barcode is read etc.

If set to “Sound beeper.”, the beeper is sounded when the barcode is read correctly.

By changing the Beep.Settings.Device value, it is possible to specify “Beeper only”, “Vibrator” only, or “Beeper

and vibrator”.

4.4. Barcode Data

 BHT-700B

Read barcode data is stored in the barcode buffer. The buffer is 99 characters in size and can store data for a

single input operation. Use the Scanner.Input method to read data from the barcode buffer.

The read barcode type and number of digits can be acquired. By checking the number of digits, it is possible to

check whether the read barcode data has been stored in the barcode buffer.

 BHT-700Q

The barcode buffer can store data for a single input operation, and is capable of storing 2D codes of 8192

bytes in size (a single Kanji character represents 2 bytes) and barcodes of 99 bytes in size.

The read barcode type and number of digits can be acquired. By checking the number of digits, it is possible to

check whether the read barcode data has been stored in the barcode buffer.

4.5. Check Digit Calculation

It is possible to calculate the barcode check digits. This function is used when adding check digits to a barcode

with no check digits.

Check digits in barcode data currently being read are automatically checked by specifying “With check digit” at

the Scanner.RdType property and enabling barcode reading.
