Wasp Bar Code WWS500 用户手册

The 'Beep and Delay' configuration supports the general control options for the
Wasp WWS500 Freedom Scanner. 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 bar
code, if some stray or scrambled characters appear, increase the intercharacter
delay to slow down the transfer rate.
