Worth Data RF Laser user manual Accumulate Mode

Accumulate Mode

Accumulate Mode is an option (which can be enabled or disabled using the RF Laser 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 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.
