Ultimately define the inputs and outputs of the system. Proprietary hardware such as IO extenders also included on the schematic would

Again these are of course by our definition black boxes. Crestron’s CAIP scheme and subsequently CSP (Crestron service providers) has, at its core, the requirement for programmers to produce a functional specification but even this is not standardised across the body of CSP’s.ĭSP’s are common place in mid to large systems.
Infocomm, pre Avixa did some good work on this but this is not widely adopted across the industry.
#CRESTRON SIMPL DIMMER EXAMPLE HOW TO#
To discover the actual requirement we need a functional scope which has hopefully been produced by some good needs analysis that informed the system design.Ĭontrol systems in the form of processors and touch panels with IO allowing control over 3rd party devices have been around since the 80’s and the discussion over how to specify their operation has produced little in the way of standards. System turns on and off based on an internal timeclock and Button 1 raises volume and button 2 lowers volume. On functionality we can make some assumptions but without some additional information they are just that.īutton 1 turns system on and Button 2 turns system off. Take a simple system with a two-button keypad and a display.Ī Schematic showing a control system a content player and a display accurately describes the system. Have a great weekend.It’s reasonable to glean from a schematic alone that the functionality of this piece of hardware in this system is to display a video stream of the connected source and that power and input control will be using the RS232 port.Ĭontrast this with a control processor pre-Ethernet. It's great to have this resource available to help me along the way as I learn. I read the F1 help last night and I did manage to get the logic completed and ready for bench testing which I hope to do here early next week with my employer. Along with those an all on/off, dim up/down, and individual off control. 3 lighting loads, each will have 3 presets of 75%, 50%, and 25%. I'm looking for either an example program or any extra resources that could lead me in the right direction. I looked on Crestron's website and did not see an example program to follow along with. The area i'm held up with is the added lighting to the system which consists of CLW-Dimex-P dimmer switches and slave dimmers. I have everything completed as far as the Xpanel, the logic to control the video sources, and an AAE to provide room audio. Im working on my first program for my work. Matt toggle quoted messageShow quoted text I find that helps me find the little(or big) features that make a difference in programming, especially with a device I haven't programmed before. Don't just skim.read everything and let it absorb. I'd also drop one in your program and hit F1 on every slot under the device. Connect a couple desk lamps with incandescent bulbs and try out different configurations/setups. I'd setup a processor, RF gateway, and two switches on a test bench. I can get very complex, but my point is to start SIMPLE first and add the more complex scenarios as needed. Or maybe you've used button caps instead of a rocker and you add a actual House Off button there. Quite often I will have 40 out of 50 switches using their default logic, and maybe a handful that use remote logic (there is a setting in slot 4 - Dimmer UI settings.) One example would be a switch by the front door - perhaps a single tap would turn off the light near the front door, but a double tap of that button could do a house off function. In the case where you will be triggering "scenes" from keypads that contain many loads, then you will have to do some more programming in SIMPL. Perhaps you might only attach two digitals to that switch: Recall_Pre_1 and Off. If this is a case where the switches installed will for the most part only control the load they are attached to, then there is little programming to do on your end. By that, I mean there is a LOT of built-in functionality to the CLW-DIMEX-P. Please describe the layout of the dimmers involved and how you want them to operate.
