Abstract

A resource controller 1 having a validation section 2 and a control section 3 for controlling for controlling mobile resources. The validation section 2 has an ID comparator 13 with an associated counter 14 an ID memory 15 and an active low ID latch 16. A data input latch 12 has a checksum comparator 20 and an associated checksum latch 21 and a checksum memory 22. The control section 3 has a crystal oscillator 30, a frequency divider 31 and a resource clock 32. The control section 3 also has actuation means provided by a twelve volt stepper motor controller 40, a solenoid 41 and an emergency override swith 56. The crystal oscillator 30 provides the clock input to a serial interface 10 and to the stepper motor controller 40 for controlling the operation of both validation and control sections.
