4QuadScan Control Methods

QuadScan models can be controlled in one of 3 different ways: Front Panel, RS-232/422, or InfraRed Remote Control. The following sections detail the use of each of these control mechanisms. In all cases, the state of a particular function of the QuadScan is indicated on the QuadScan’s Front Panel LED readout. On power-up, the LED display indicates “QUADSCAN”.

4.1Front Panel Control

The QuadScan Front Panel gives the user access to all of the control parameters detailed in section 3.1. Figure 2 indicates the placement of the buttons and LED display on the Front Panel of the QuadScan.

The controls are arranged such that the user can cycle through a circular list of controllable functions with the + or - buttons. Using the + button advances the controlled item to the next item in the list. Using the - button reverses the controlled item to the previous item in the list. Depending on the nature of the controlled item, the directional arrow buttons function differently.

If the controlled item is a Toggle (i. e. Channel Termination, Zoom, etc.) with a position of either On or Off, then the activation of any one of the arrow buttons will toggle the state of the controlled item.

If the controlled item is a Multiple Choice (i. e. Input Source, Output Resolution) with several mutually exclusive positions, then the activation of the Up Arrow or Down Arrow buttons will Increment or Decrement the state of the controlled item to the next state. When the last state is reached, the next state will be the first state.

If the controlled item is a Range (i. e. Input Horizontal and Vertical Size and Position, etc), then the arrow buttons increase or decrease the value of these quantities. The increase or decrease is proportional to the length of time that the button is pressed.
