Matrix Analog vs DM Tool
|
Folks -?
When routing analogs with a touch panel to a Matrix everything works great. When I use both DM Tool + Touch Panel things go weird. If laptop is analog 1, and I press laptop on the touch panel, it routes. When I manually then use DM Tools to switch to input 2, when I press laptop on the touch panel again, it does not route. I have to route away from analog 1 (different source) then back to laptop, then it takes. Is this an issue where, even though I manually switch using DM Tools, if the analog value already propagated in SIMPL (laptop 1), sending the same value again will not repropagate and make the switch on the touch panel? Any information would be greatly appreciated. AV_Programmer |
¿ªÔÆÌåÓýYou need to look at the signal path from the button press to the DM analog input and the propagation characteristics of each signal along the way. ? Also how are you triggering the ENTER on the DM frame? ? If you had an INIT connected directly to the DM analog the INIT should repropagate through to the DM frame and all Bueno when the button is pressed. ? On the other hand, if you have analog buffer or crosspoint between the INIT and the switcher this is the expected behavior because those only propagate values that have changed from the left to right ¨C eg if the left side is 1 and the right side is 1 the right side will never see a change no mantter how many times you init the left side ¨C this can be very handy in a lot of cases but cause trouble in others. There are solutions like running a serial buffer instead of or in parallel with the ABUF, using XSIG symbols to encapsulate the analog value into a serial before routing it through a crosspoint, etc. but thos all have varying considerations as far as processor workload, ease of maintenance of the program, etc. ? -- Lincoln King-Cliby, CTS, DMC-E-4K/T/D ?

¿ªÔÆÌåÓýIn parallel ¨C out of an abundance of caution I won¡¯t post the detail from the SIMPL Windows Help here but compare and contrast the descriptions of the SBUF and ABUF relative to enable being high. ? The ABUF propagates on transition of enable to high or when a new value on the left side arrives that does not match the value on the right side. The SBUF propagates on any value change but not a transition of enable to high. ? The SBUF/ABUF naming is one of those weird quirks of Crestron that has persisted since the beginning of time or thereabouts. ? If you aren¡¯t using the enable on the ABUF and want all values to propagate you could also use just the SBUF instead. ? ? -- Lincoln King-Cliby, CTS, DMC-E-4K/T/D ?
