Microprocessor control permits the simultaneous data collection of a virtually unlimited number of photo diode channels. Using advanced networking features, processed-pin-photodiode data may be communicated to a single host computer. Network communications provides facilities to perform calibration, diagnostics, and in-system firmware upgrades.

Orchid selected a Freescale MC9S12A128 microcontroller as the brain of this low cost, multi-channel transconductance amplifier. The HCS12's feature- rich complement of flash program store, static RAM, timers, analog to digital conversion circuitry, and robust processor reliability make the HCS12 a perfect fit. CodeWarrior software development tools unlock the power of the sixteen bit HCS12 processor. Complex filtering and mathematical algorithms may be implemented on the transconductance amplifier board itself.
