If we go ahead and save this file as Autopatch Parse Test, then select Build -> Save And Compile, (or just hit F12) you'll see that our four-line module is A-ok as far as the compiler is concerned: In the window that comes up, just go ahead and delete all the text, and add these lines:ĪNALOG_OUTPUT audio_stat, video_stat Īside from coloring, your screen should look something like this: When the SIMPL+ editor appears, we want to select File -> New -> New SIMPL+ Module. To start out - in SIMPL, we'll go File -> New SIMPL+. That leaves us with the need to create 8 analog signals in our SIMPL program - 4 for audio, 4 for video. For the sake of simplicty, we're going to say that we're using an Autopatch half-Y 12x4 switcher. We want both audio and video status, as our system application calls for the possibility of breakaway routes. So given the strings coming in from the switcher, we want a set of analog values in our SIMPL program to reflect which input is currently routed to which output. We've now been tasked with the requirement that we obtain feedback from the unit to acknowledge our commands AND let us know if a user has simply gone up to the front panel of the switcher and manually done a route. Let's assume that we've already got a program going that uses the autopatch BCS protocol to initate routes.

For example, the string 'CL2I3O4T' coming in the com port tells us that the switcher has just routed only the video (level 2) from input 3 to output 4. T - for 'take' is the delimiter used by Autopatch to represent the end of a command. In this case, x represents the 'level' being switched - for a basic audio/video switcher, x represents a route on the audio level, 2 the video level, and 0 represents an audio follow video route. For part 1 of this example, we're going to work with responses to the Autopatch route command, which comes in this format: 'CLxIyOzT'. Two good things about Autopatch - a) The protocol is the same across all of their products, and b) operations done from the front panel create the exact same command strings as those sent across the RS232 connection. For this example, we're going to use the protocol for an Autopatch matrix switcher. A request was made in the Crestron discussion forum for some help with parsing strings in SIMPL+.
