BEEP AND DELAY

The 'Beep and Delay' configuration supports the general control options
for the WCS3900 Series Scanners. These options include the volume,
intercharacter delay, and interblock delay.

Interblock delay is the minimum time interval between two adjacent scans.
If the processing speed of your host device is slower than your scanning
speed, a longer interblock delay may ensure the data integrity.

Intercharacter delay is the time period that the scanner will wait before
transmitting the next character. If data sent by the scanner has incorrect or
missing characters, a longer intercharacter delay may solve the problem.
The intercharacter delay should be changed only if the transfer rate cannot
be maintained between the scanner and the keyboard buffer of the
computer.

Note: The default for the intercharacter delay is set to '140us' and is the
most common configuration; however, your PC may be different. When
you scan a barcode, if stray or scrambled characters appear, increase the
intercharacter delay to slow down the transfer rate.
