Maintained and added features to firmware in multiple closed-circuit TV security system modules

The security systems were made up of different modules connected to each other via a serial connection. These modules included such things as alarm sensors, camera controllers, and other security devices, all controlled and monitored via software on a PC. I fixed bugs and added features to several of these modules, including a modified version of the camera controlling firmware to support a user requested camera type.

Did onsite configuration debugging

There were several times where our technical support people could not get an installed system working correctly. I was sent to these sites (i.e., EDS, USAF, etc.) to do real-time debugging and fix them. Some were mere configuration problems, while other turned out to be bugs. I fixed the bugs on-site and installed the new firmware.

Developed DOS based serial communications logger/debugger

To aid in our debugging I developed a tool to allow us to intelligently process our serial streams. The software included view multiple serial streams, capturing data , filtering data, triggering on specified data and/or patterns.
