| The Ultimate I/O is a output controller with 96 outputs all supporting 256 pwm levels with a PWM frequency of 100khz. Since the outputs of the unit are constant current drivers providing 20ma each, leds can be connected directly to the outputs (no resistor needed), but booster circuits must be used to driver higher loads (e.g. Cree leds). Up to 2 Ultimate I/O (currently) can technically be used with the DirectOutput framework as supported by the PacDrive SDK (ask Ultimarc for firmware to program second ID), but this has not been tested nor confirmed.
