Communication Setup (Cable Configuration) 4-7
Beep on BEL
When enabled, the scanner will beep when a <BEL> character is
detected on the RS-232 link. <BEL> may be used to indicate an event
such as an illegal entry.
Unknown Characters
Unknown characters are characters not recognized by the scanner. When
SEND BAR CODES WITH UNKNOWN CHARACTERS is enabled,
all decoded bar code data is transmitted except for the unknown
characters. If this option is disabled, bar codes containing one or more
unknown characters are not transmitted.
Response Timeout
The response timeout determines the maximum amount of time the
scanner will wait before it assumes the end of a transmission. The
timeout period may be from 0.0 to 9.9 seconds in 0.1 second increments.
The default is 2.0 seconds.
To enter a new timeout, scan the timeout label followed by the two digit
timeout. The decimal point is fixed between the first and second digits.
