Cardax FT Controller

The Cardax FT Controller is an Intel 386ex based controller with 8MB of RAM and 4MB of Flash memory. It has three RS-232 serial ports, a 10-BaseT Ethernet port and a high speed RS-485 port (for communicating with the field units).

The controller is the key component in the Cardax FT system and it provides card access control and monitoring independently of the head-end PC. The on-board Flash memory is used to store cardholder access criteria and system configuration as well as for logging events, alarms and images when the head-end PC is off-line.

The software for this device is written in C++, C and assembly language.
