Beep and Delay
The 'Beep and Delay' configuration supports the general control options for the Wasp WLR 8900/8905 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 bar code, if some stray or scrambled characters appear, increase the intercharacter delay to slow down the transfer rate.
