Like most barcode scanners, the PecuMecu TM-10C scanner is configurable by scanning magic barcodes. A manual and quick-reference card are included with the scanner, but seemingly not posted online. Below is a table containing the data and an image of all barcodes in the manual. The data of all barcodes starts with a 0x80 byte, followed by the string "WSM", followed by 8 ASCII digits, followed by a period character. The images in this table were generated with qrencode. They are not identical to the barcodes in the manual, but they represent the same data.
