- Designed a production test system for a wireless facility access control system. Hardware consisted of commercially available parts (controllers, analog and digital I/O modules,
power supply, data converters) and product specific software. Java Swing GUI application interfaced to two serial (RS-485) I/O controllers and a serial (RS-232) ASCII-to-Wiegand data converter.
- Designed a module tester for components of a facility access control system. Hardware consisted of a portion of the overall product, modified for test and software consisted of a Visual Basic GUI-based application serially interfaced to the test hardware. Hardware modifications included PCB changes as well as changes to Microchip PIC processor firmware.
- Wrote TL1 message handler twice to meet customer needs despite limitations of third-party equipment.
- Wrote embedded firmware in both C and Assembly for network interface units for T1, E1 and DS3 digital telecom formats. Processor platforms includ
