Lutron Grafik Eye issues

Good Morning, 

 

I am having difficulty getting the lutron Graik Eye 3000 and the GX-RS232 to connect to the Global Cache 100

 

When I open up the RS232 box LED 1 is blinking which means its talking to the Grafik Eye 3000. But once I plug the rs232 into the global cache and use the drivers supplied by iRule there is no response. Does anyone have files or xml drivers that I can use? I have checked with my Cisco guy and the internal network is wide open so there is no ports being blocked 

 

Thanks ahead of time.

When dealing with serial command data, it is important to make sure you are using the correct cable and command syntax for the hardware. Once those have been confirmed, connector settings such as the baud, parity and flow control will need to be confirmed as well. These are dictated by the controlled hardware specification and will be different for each application. After that, using a loop between pins 2 and 3 on the serial connector in conjunction with our testing utility will allow users to see if the data being sent is coming out properly. I have linked the iTest utility below.

any ideas what the wiring pattern from the Lutron would be to the Global Cache, The lutron has a custom cable that just has a connector on one end and the other ender is the DB9  

RS232 Link of RS232 Interface (the GRX-RS232 

1. Common

2. Data In

3. Data Out 

4. + Voltage In

5. - Voltage out. 

 

I have to make them match the correct in out for the Global Cache.

Our serial interface is as follows:

pin 2: Transmit

pin 3: Receive

pin 5: Ground

pin 7: Request to Send

pin 8: Clear to Send

Any connection made between our serial port and that of another device will need to match so that the devices are able to properly communicate with one another.

Great it looks like a just gonna to do some fancy wire switching and tone it out on the DB9 end to make sure it matches and we should be in progress.   

Is the request to send and Clear to send the same as Voltage + in and - Voltage out?

I do not think so. The way that these lines are used will need to be determined by the Lutron specifications. This may be for some purpose which does not have any reason in this setup, so you may not even need to use them. Be sure to know what voltages are present on lines before connecting anything in order to prevent damage to your unit.

what voltages am I looking for on the RX and TX?

On the global cache end does the request to send and clear to send need to be connected to something in order for it to work. 

 

Thanks

You will see a +-5 to 8V voltage on the transmit line, but you shouldn't have to worry about transmit and receive as they will connect to the other hardware's transmit and receive lines which shouldn't cause problem. The RTS and CTS lines are used only when the hardware (in this case the Lutron piece) requires hardware handshaking. If it does not, then you will likely have no problem leaving the lines open.

Any idea on how to create xml files for the global cache rs232 control?

Our RS232 is a simple terminal connection allowing for a transmit and receive. Questions regarding files & formats necessary for software to work properly will need to be directed at the company responsible for the control software.

Hi there,

I am going to install Lutron Grafik Eye QS system, using iRule and Globe Cache to connect.  Since I just need a very simple control of my Lutron's connected lighting and curtains, I don't need a R232 conenction.  IR 1-way connection is good enough for me.  The good news is there is IR connection, like a Relay port at the back which I need not a IR emitter stuck at the surface (yet to find out the details and I am not a technical guy, just DIY try out for budget and self interest reason)  The bad news is I don't know how to connect them with the Global Cache.  Appreciate if there is tips on this area.  Many thanks.

Following the above, attached with the latest manual of Lutron Grafik Eye QS.  Page 7.

For some reason I am unable to view your attachment, but I can give you an explanation of what I would imagine your setup is going to look like. You will need codes, which you will likely be able to learn with our hardware without an issue. From there, you will need to make sure first, but your emitter can likely be removed from the end of your cable and the two wires can be wired into the terminal connection to receive the IR commands. You will need to determine whether or not the hardware uses the same protocol for the terminal input as it does for the IR signal, and you will need to check to see if you need to put a certain wire into a certain portion of the terminal. If the Lutron piece does not supply a voltage to the terminal connector, then you should be safe connecting the emitter cable directly to the terminal to see if the commands can control the device.

Thanks for the input from Josh which gave me a list of technical things which I need to consider.  Lutron just gave me a configuration which they have recently a client connected Grafik Eye QS to a Xantech product.  

When I talked to the sales of Lutron, I asked if it is as simple as cutting the end of IR Emitter and connect the two copper cables into the two holes of Grafik Eye QS.  They said "yes".  However, I have concern whether if there is difference between the two cables, e.g. + / -.  What will happen if I connect the + / -, if any, the opposite way?  They then have no specific answer but forward me the attached.

Hope you can open my attachment this time and give your valuable advice.  Many thanks.

Luckily I can see the attachment from this message. I can't tell based on what you sent over, but if there is no voltage present on those two lines then you are safe connecting our emitter output to this connector. One thing to know is that the signal is sent over on the line connected to the tip, and the ground is connected to the base of the connector. If this does not work, then you will want to know what sort of input voltage level the Lutron piece is looking for. If it operates in a Xantech compatible IR environment then you will need to use a conversion cable (GC-CGX) in order to convert our output to work properly with their input.

Related to William Chan's query regarding connection IR emitter from GC-100-12. to Lutron Grafik Eye QS, it is very a very simple ecercise. I have  tested connection last week with the engineer of Lutron's dealer in HK last week. Just cut the emitter wire and directly connect to the IR terminal at the back of the QS unit. The QS will take the electrical signal from the IR output of GC-100-12. Hope this input can clear your concern.

Great.  thanks for the update.  I am using iRule, so the remaining issue is how much can iRule control the QS, i.e. how many scenes, 8 or 16? and what else can iRule + Globe Cache control the QS?  Lutron dealer is going to install QS in my new home in coming two weeks and I will test out the whole thing in early Sept.

16 scenes. IRule control Global Cache which can control QS's lightings plus curtain if you like.

Getting more excited!  Good to hear iRule can control 16 scenes.  I learnt from dealer than Lutron QS remote control can only control 8 scenes (the first 8 scenes programmed in QS), so I expect iRule, as a replacement of QS Remote Controller, can control only the first 8 scenes.  I assume that I can use the available database from iRule to control QS's 16 scenes.

Just trying to explore further, when you said control lighting or curtain, you mean the lightings and curtains that included and set in the scenes, right?  You do not mean iRule can control each and individual lighting or curtain, on the top of scenes...??  (I am a bit going too far!)

Hi , I was reading the forum and I am interested to link the graphik eye via rs232. It was not quite clear to me if I will need to modify my cable or not . Does anybody Know the answer ?

William/Josh, 

I am trying to achieve something similar - control Lutron Savoia QS through iRule and iTach IP2SL or IP2CC.  

Here are some questions

1. Will the iTach be sufficient to control the shades through iRule or will I need addl hardware ? (Assuming we can create the command strings in iRule)

2. Which iTach - IP2Sl or IP2CC - will work with Lutron smart power panel ... http://www.lutron.com/TechnicalDocumentLibrary/045-310%20QSPS-P1-10...

Appreciate your inputs.

What you will want to make sure of is what the control interface is for the smart power panel, and what the command structure looks like. This will determine whether or not the device can be controlled by our units, whether you need any intermediate hardware between our unit and the device, and should put you on the right track for getting control of your lighting through iRule. If you do get a good break down of how this device is controlled, paste it here and I should be able to tell you what you will need to control it.

Josh,

Here is a quick update. 

Lutron uses a 2-way RS232 interface.

And,

Here are the specs for the Integration Protocol and Wiring Diagram. Pl note that we can eliminate the NWK-e by going directly through iTach, and create all the commands in iRule.

 

Appreciate your inputs.
