RS232 Protocol Converter
KeyPad Configuration Interface
The Client
A local school district using the Zangle student information system.
The Challenge
The schools have an abundance of legacy RS232 key pads that were previously used to input student ids in the cafeteria checkout lines. The keypads were no longer compatible with the Zangle software currently used at the checkout terminal. An application was needed to translate RS232 output from the key pads and convert it into Windows keyboard input. The text strings emitted by the key pads also needed some character conversion.
The Solution
A C# application was developed by Huron Data Solutions to facilitate the conversion of data from the key pads. The KeyPad Converter application installs natively as a windows service. It offers a graphical interface for configuring and debugging the key pad communication, as well as allowing configuration of data validated performed by the converter program.
