Abstract: A car wash controller for receiving input data from a plurality of remote input devices and for controlling the operation of multiple remote output electrical devices. The central controller is coupled to a series of input boards by a communication cable, such as a telephone cable, to receive input data from the input electrical devices. The input boards can be coupled to each other to reduce the amount of wiring within the car wash environment. The central controller is further connected to a series of output relay boards, each of which are connected to a supply of power. The central controller is connected to the output relay boards by a communication cable such that an output command can be sent to each relay board to supply electrical power to the output electrical devices. The relay boards can be coupled to each other to reduce the amount of wiring within the car wash environment.

Abstract: A method and system for utilizing remote code generation terminals to generate authorization codes that control and authorize the activation of a service device. The remote code generation terminals each allow a customer to select between multiple service levels for operation of the remote service device. The code generation terminal generates an authorization code that includes various groups each having a specified number. The groups are encoded into an authorization code, which is then encrypted and printed for the user. The customer enters the encrypted co authorization code into the remote service device that validates the authorization code and begins operation of the service device. A computer controller in the service device keeps track of the used authorization codes in its own internal database such that each authorization code can only be used once.
