Cleaned up links to other sheets.
Changed regulators to through-hole components. Updated pin numbering to suit. Changed PNP clamp transistor to through-hole component and updated schematic accordingly.
Removed CBUS IO header and LEDS.
Changed MAX232 IC to DIP16 variant.
Updated AAP sensor part number due to part availability.
Changed Logic IC to use spare gate from CAS circuit.
Moved spare gate to digital input - wakeup circuit. Also showed logic gate supply connections.
Changed TC4427 IC to TC4424 as per MrOnion's suggestion. Thank you Mr Onion! Also removed output leds and cleaned up schematic aesthetically.
Changed to through-hole FET's. Removed LED's.
Changed to through-hole FETs. Removed LED. Changed ground connection to INJ GND.
Used same logic IC as CAS circuit. Cleaned up schematic aesthetically.
Removed VSS input connection.
