[. . . ] SIMPL Windows is Crestron Electronics' software for programming Crestron control systems. It provides a well-designed graphical environment with a number of workspaces (i. e. , windows) in which a programmer can select, configure, program, test, and monitor a Crestron control system. The next two subsections describe a sample SIMPL Windows program that utilizes the CNXFZ. The first subsection details how the sample program works with a textual description and block diagram. The second subsection provides a broad description of how to actually create the SIMPL Windows program. A third subsection, "Application for an Alternate Method of Control" on page 15, is provided to offer an alternate method of control. An example program is referenced, but details for creating it are not furnished. NOTE: The following description assumes that the reader has knowledge of SIMPL Windows. If not, please refer to the extensive help information provided with the software. Operations Guide - DOC. 5753 CNX Focus/Zoom Control Interface: CNXFZ · 9 Focus/Zoom Control Interface Crestron CNXFZ NOTE: There is no need to recreate the sample SIMPL Windows program. A similar copy of this program is available from Crestron's ControlCD (version 5. 2 and later) or the Software Downloads page (Examples Library) of the Crestron website (www. crestron. com). This zipped file contains the necessary files to recreate the following programming sample. How the Program Works A basic CNXFZ SIMPL program is shown on the next page in block diagram form. For this example, the SIMPL Windows program controls the CNXFZ through the use of nine analog signals. Block Diagram of System Incorporating a CNXFZ 10 · CNX Focus/Zoom Control Interface: CNXFZ Operations Guide - DOC. 5753 Crestron CNXFZ Focus/Zoom Control Interface Positional Feedback Signals Positional feedback signals are generated by the networked CNXFZ and input to the rest of the program. Two analog positional feedback signals, FOC_POS and ZOOM_POS, represent the current focus/zoom lens setting. The CNXFZ converts positional potentiometer wiper voltages to analog positional feedback signals. In general for example, an analog level of 0% on ZOOM_POS indicates that the lens is at its wide shot (wide and tight shot descriptions may be reversed for some camera lens, consult the manufacturer). An analog level of 100% on ZOOM_POS indicates that the lens is at its tight shot. Drive Signals Drive signals are generated from the SIMPL Windows program and output to the CNXFZ. There are two types of drive signals, position and rate. Each type is comprised of analog programmed outputs for the CNXFZ. Two position drive signals, FOC_SET and ZOOM_SET, are used to instruct the CNXFZ to drive the camera to a preset position. Anytime the analog level on one of these drive signals change, the CNXFZ adjusts the corresponding focus/zoom lens position until the feedback matches the level at the programmed output.
