12-6. Using a Bar Code Reader

 The bar code reader can be connected to the RS-232C interface on the scale. It can

read bar codes for the ID number, unit weight, tare weight and comparator limits.

 Any of the RS-232C interfaces can be used for the bar code reader.

 Set the F-Function f-06/07/08-01="5" to use a bar code reader.

For example, to use Ch.1 (PORT 1), set f-07-01="5".

 Refer to “13-1. OP-01 Bar Code Reader” about the optional bar code reader.

Requirement for the Bar Code Reader

Interface EIA RS-232C

Baud rate 2400, 4800, 9600 bps

Character code ASCII

Terminator C

or C

Bar code EAN/JAN, UPC, Codabar (NW-7), Interleaved 2 of 5,

Code39 etc., depending on the bar code reader.

Connector D-Sub 9pin connector (recommended)

In most cases, a bar code reader with an RS-232C interface is to connect directly

with a personal computer. The signals must be converted to connect this kind of bar

code reader with the scale. Refer to the diagram below.

Do not use RS-232C adapter/cable to connect the bar cod reader (OP-01) to the

RS-232C interface on the scale.

Some bar codes will have start and stop characters. But, set your bar code reader

not to send those characters to the scale. The scale doesn’t accept such data.

EAN/JAN/UPC bar codes usually have a check digit and other bar codes may have

either. But, set your bar code reader not to send the check digit. The scale doesn’t

accept such data. If sent, the scale cannot tell the difference between data and the

check digit.
