Barcode Reader

Once the barcode reader is installed, check that it is operating correctly. See the User’s

Interface

Guide for your monitor for instructions on how to use the barcode reader.

1.Use the barcode reader to scan Test Barcode 1 and then Test Barcode 2 from the barcode sheet.

2.Check that TEST OK5 is printed on the paper. If it is not, switch the monitor off and on, and repeat the test. If it is still not printed, connect a new barcode reader.

The barcode reader interface has voltage levels of ± 12V, 9600bd, max.1 byte/20 ms. The connector is a female D-type, 9-pin subminiature connector.
