Accumulate Mode

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. A small laminated barpad card is provided with each reader

ordered to aid in entering variable quantities.

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 R/F Scanner and the R/F 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.
