Accumulate Mode (1D only)
Accumulate Mode is an option (which can be enabled or disabled using the Reader Setup Menu's Code 39
section) allowing the reader to accumulate multiple bar codes in its buffer, then transmit them to the computer
as if they had been a single bar code. This is useful for entering quantities and other variable data.
It works with Code 39 only, and can't be used with a check digit. When the reader reads a bar code with a
leading space, it beeps and buffers the data without transmission. It continues to read and buffer bar codes (up
to 40 characters) until it reads a bar code without a leading space. Then the entire buffer (including that last
code) is transmitted as one long bar code. A bar code of a double minus (--) sign clears the buffer. Scanning a
backspace code ($H) backspaces in Full ASCII mode. A handy code for
Enter
(as seen on the "Barpad"
below) is a Start/Stop only. (No data.) The code to use for testing the transmission link between the RF Laser
Scanner and the RF Base Station is the CLEAR BUFFER code (the same bar code as titled Link Test on the
Setup Menu. It will cause beeps to be heard, but no data will be transmitted to the computer -- testing blind
with no computer consequence.
This numeric "Barpad" illustrates Accumulate Mode. Scan
5, 3, 8,
and
Enter
. The reader transmits a single
message of
538.
