Cardax FT Remote Units

Cardax FT Strike Controller. This is an input/ouput board with 6 general purpose balanced inputs and 4 general purpose relay outputs, that is designed for use when controlling and monitoring two doors.

Cardax FT Prox Reader. This is a proximity card reader without keypad for use when PIN entry is not required for card access.

Cardax FT I/O Board. This is an input/ouput board with 15 general purpose balanced inputs and 5 general purpose relay outputs, that may be used to control and monitor doors, passive infra-red (PIR) detectors, reed switches, plant alarms, time-clock relays or other inputs and outputs in the building.

Cardax FT Relay Board. This is an output board with 20 general purpose relay outputs, that may be used to control doors, time-clock relays or devices in the building.

The above devices all use the Dallas 87C520 microcontroller with software written in assembler and C.

My involvement with these products has been in system design, communications protocol design and assisting the software engineers who implemented the software for them.
