voltage ramp output for 3 series
Jeff Wagner
I am changing out a Pro2 for a Pro3. The Pro2 has a CNXAO-8 to control an audio processor but this card won't work in a Pro3. So far I haven't found a Crestron devices to provide the 0-10v ramp that I need. Is there a workable Crestron solution or do I have to go to a third party device like the Extron ?
Thanks, Jeff Wagner UC Santa Cruz |

Re: Servo Shade Control
Yes, that looks like it would work nicely. On Wed, Jul 5, 2017 at 2:55 PM, richie_nelsen@... [Crestron] <Crestron@...> wrote:

Re: Servo Shade Control
?The S3003 servo requires you to provide a 3V-5V squarewave pulse, every?0.0015 second to every 0.0019 second (depending on the position you want) in order to hold the servo position...Good luck getting a Crestron processor to provide that. ?As soon as you stop pulsing the signal, the servo will stop holing it's position. ?

Re: Servo Shade Control
Controlling these from a serial port is definitely going to cause you to have a burned up processor and/or port. They aren't meant to do PWM nor can they supply enough current for a motor.
Use an Arduino to handle the PWM as they have built in libraries and tons of examples along with motor driver shields that are meant to do motor control. You can use the serial (pins 0 & 1 on arduino) along with a serial logic level converter to step it to ~12v then you can use a Com port along with an SIO and your own protocol to go between them. There are tons of online resources on how to do this. Including on Arduino's web site and within their software. |

Servo Shade Control
Hi All, I came across a hacker project to automate your shades using a $13 Futaba S3003 servo. I have the servo wired into?the com port on my MC3 and can get it to react to serial commands but can't figure out how to get it to stay in an open/close state.?I found a post that says?the following: "To control the S3003 you need to provide a PWM signal of between 1ms and 3ms (2.5ms?) every 20 to 50 times a second. The good news is that you don't usually need to buffer the signal - it can come direct from the PIC pin to the S3003 servo I/P pin. As for programming this PWM - there are many ways of generating the PWM. However, the one thing that is important is that the PWM Mark time is consistent (minimum jitter). So I usually use a timer to generate the Mark-Time aspect of the PWM signal. The Space-Time is a little more forgiving and can vary alto." This link may also be helpful: Any pointers would be much appreciated. Thanks! |

Re: TPMC-4SM - SD card faliure
¿ªÔÆÌåÓýCouldn¡¯t you just boot the panel on an isolated network segment [or disconnect the original 4SM] and use MACA at console to set the MAC to the preferred/original address? ? -- Lincoln King-Cliby, CTS, DMC-E-4K/T/D ? From: Crestron@... [mailto:Crestron@...]

Anyone aware of how to copy SD card from a working TPMC-4SM to a unit with a bad SD card, and preserve the MAC of the second unit? Appears the MAC is stored on the SD card, which is a bummer. Have like 10 TPMC-4SM units that were running old firmware and fried the SD card.

Re: 3 series internal memory failure...AGAIN!
"So after several processors having internal memory card failures, I have
very little confidence in the reliability of 3 series processors. ?What
is everyone else's experience with this?"
Been working with 3-series since they came out and have not had a single one fail with a memory card issue.? In fact, I'm not sure I'm aware of any installed processors needing to be replaced for any reason, period. That includes the MC3 running my home AV system... I do remember a story about a Crestron engineer that had to delay the start of their vacation to investigate mysterious issues at a large client's site.? Turns out the developer's code was writing to a file with some kind of unnecessarily high frequency and killing the cards in all the processors at the site... ? - Chip |

Re: DM-RMC-4K-SCALER-C
¿ªÔÆÌåÓýThere should be someone on pager duty if you really have to get it fixed today, but first¡ ? RMC may be stuck in bootloader. If you have access to a DM frame, try connecting it to a DM output and doing REPORTDMNET in text console on the matrix and see if (and how) it reports. ? If you don¡¯t have access to a DM matrix, do the same thing from the transmitter. ? If you see it report, usually the easiest thing is to run PUF tool pointed at the non-RMC side of the equation, and PUF tool should pick up the RMC even in bootloader and either automatically select it or allow you to manually select it to push firmware. ? If it is reporting, but PUF tool isn¡¯t playing nice you may have to go the more circuitous approach of extracting the specific firmware from the PUF, setting up an indirect connection in Toolbox, and manually updating the firmware. ? If it doesn¡¯t report at all, it may be time for an RMA ? -- Lincoln King-Cliby, CTS, DMC-E-4K/T/D Commercial Market Director Sr. Systems Architect | Crestron Certified Master Programmer (Gold) ControlWorks Consulting, LLC Crestron Services Provider | Biamp Audia Certified | Extron Control Professional ?

Hi everyone, ? Understand TB is closed today, I am wondering if any of you can shed some light on issue connecting to RMCs. ? I have 11 RMC's ?- Tx pair in which each RMC is connected to a network switch with DHCP server on. Originally, I was able to see all 11 RMC's but when I performed puf?update via script manager, 5 out of 11 failed (during scripting upgrade, I was connected to the switch and only updated RMC's together).? ? I was like no biggey as it's not the first time an update has failed so I tried to connect to each directly without any tx attached. Currently, I can't connect to any of this 5 RMC's. I tried resetting, setting them to static IP. ?Even after setting them to static IP, I can't discover them or ping them at the default IP (my pc ip?was set to 192.168.1.200 and pinging to .221). ? Weird part is that If i attach tra nsmitter to each of the receivers and tie the lan?of rmc?to switch with dhcp, i can see all the transmitters and able to batch upgrade them without a problem but can't seem to connect to any RMC. ? Any thoughts? ? ?

Re: 3 series internal memory failure...AGAIN!
Then they need to make the SD cards field replaceable period. It's a complete joke that the entire processor has to be sent back to replace a $10 SD card. I've had a few MC3s sent back because of this. I was told that early versions of the SD cards were not setup correctly which is what causes the early failure. Crestron knows about this but has decided to just charge us for the mistake.?

British Gas Hive Integration
Hey folks,
Any of you integrated Crestron with British Gas Hive products? I have a client who wants to control multiple Hive Active Plugs. They appear to use a although this is not officially documented and could very well change in the future (there have been several iterations already within a short period of time). I was looking at the Crestron which would probably do the job...if the international 230V version exists. Any advice? What do you use / recommend when your client's need to switch a handful of mains sockets on/off in various rooms? Thanks in advance, Fred. |

Re: Fusion SSI. Multiple Rooms in 1 program
The largest I can attest to is 5x Fusion Room full modules ( each with Scheduling Awareness, 4x Static Assets etc) per Slot.
Born out of necessity, it's a pretty wild build with 40 ( SLOTS 2-9 x 5 each) in total, with SLOT1 handling all Fusion in/out comms from internal EISCs. CP3 alive and stable for 6 months straight. |
