Continuous reading mode (
C)
OPEN "BAR:C" AS #7 CODE "A"
Upon execution of the above statement, the BHT turns on the illumination LED
(laser source
*2
) and keeps it on until the bar code device file becomes closed,
irrespective of the trigger switch
*1
.
While the illumination LED (laser source
*2
) is on, the BHT can read a bar
code.
Once a bar code is read successfully, the BHT cannot read the next bar code
as long as the entered bar code data is not read out from the barcode buffer.
• If
readmode is omitted, the BHT defaults to the auto-off mode.
• In the momentary switching mode, alternate switching mode, or continuous
reading mode, after you read a low-quality bar code which needs more than
one second to be read, keeping applying the barcode reading window to that
bar code may re-read the same bar code in succession at intervals of one sec-
ond or more.
