Power up communication interface system |
摘要 |
A controller for a system has two or more operating modes. The controller operates according to a different control algorithm in each operating mode. A manually operable switch typically used for sending a reset signal to the controller, may also be used to change operating modes. The controller changes operating mode when it detects that the switch is manually operated during a preselected phase of controller operation, typically when power is first applied. The disclosed embodiment allows up to four different operating modes to be selected. A first selection of operating modes can occurs if the switch is held closed during startup and then immediately released. A second selection of operating mode occurs if the switch is pressed within a preselected time interval after power is first applied to the controller. Both selections can be made during a single start-up event. The controller may use a status light if present, to visually indicate what operating mode has been selected after the time intervals in which to change operating modes have elapsed.
