The challenge was to design an inexpensive single cavity thermoset injection enclosure and tubular support pole which could support either smartcard or magnetic reader mechanism with optional NFC (Near field communication) reader writer.
Between 1999 and 2018 over three thousand, magnetic and smartcard variants were manufactured and installed throughout South Australia, Queensland and Northern Territory.
During this time, I developed an expert knowledge coding Neuron® C, OpenLDV and Echelon's LNS® Network Operating System. I wrote an interface that enabled Windows applications to send and receive low-level messages through Echelon's LonTalk implementation of the ISO/IEC 14908 Control Network protocol, for Layer 2 or Layer 5 network interfaces. Researched and collated most of the LNS Data field structures for explicit messages, network variables, network management and diagnostics and exposed via a Dynamic-link library. Coded an ActiveX Exe out of process server for third party application.
LNS licencing and installation tools no longer required.
The device integrates a high-performance Echelon Corporation FT-5000 Smart Transceiver for the LONWORKS® 2.0 platform with a free topology twisted-pair transceiver and three independent 8-bit logical processors to manage the physical Media-Access Control (MAC) layer, the network, and the user application.
Neuron® C code highly optimised to fit into an application code block of only 42KB.
Including IO peripherals, LCD and keypad, encrypted telemetry APDU, cryptographic algorithms for BlockChain, 3DES and Mutual Authentication to Host Security Access Module and support for a total of twelve EMV compliant microprocessor Smartcard platforms.
