 Delcom USB Numeric DisplayThe challenge was to provide for lot tracking of supplies entering the production process at points distributed over an entire manufacturing site. Each supply container had a bar code label providing the lot number. Low cost USB scanners are available but lack the ability to provide confirmation that the scan had actually been read and recorded. The solution was provided by a Delcom Engineering Model 806016 six digit display. (www.delcomproducts.com). The display included a very clean enclosure and USB connectivity.
- Operators scan a barcoded label.
- Software on a Mac Mini receives the scan in an AppleScript application
- The software adds time stamp and station meta information
- Records are created in a local database and a remote database
- The last six digits of the scan are sent back to the operator station and displayed on the Delcom
To control the Delcom Display, a Framework and Small terminal application are needed. You can download a copy here (download) along with small AppleScripts for testing and source code.
