How to connect the UMI-7764 to a geared motor

Please, I have simply to connect a geared motor to the UMI-7764 thru an L293D driver.
Please, could you tell me which outputs of the UMI-7764 do I have to connect to the driver ?
Thank you.

You'll need to refer to the documentation for the L293D driver to determine which lines it need attached. For servo motors you typically atach the Analog Out line as well as the Encoder feed back lines from the UMI. For steppers, you need to at least wire the step and direction lines to your drive. I recommend taking a look at the 7764 user manual as well for help with wiring.

How do I power the UMI-7764?

The power supply says 5V, but what should the current rating of the power supply be? I just want to confirm that it is 0.2A as in the user guide, but it says " + user-defined encoder and limit power ". I do not know what that means---but we are in fact using an encoder and stepper motor, so it seems relevant. Thanks for letting me know.
Sincerely,
Christian

Christian,
0.2 A is the maximum power consumption of the active devices on the UMI-7764. If you connect devices like an encoder to the UMI, you typically power them via the +5V outputs of the UMI-7764. These outputs are feed-through terminals that are directly connected to the +5V input of the UMI, so you will have to add the power consumption of any device that draws current from these outputs.
E. g. if your connect three encoders with 100 mA power consumption each, you will have to use a power supply that is rated for at least 500 mA.

What is /INHIN1 terminal in the UMI-7764? It's not in the 7344 HW user manual.

What is the purpose of the /INHIN1 terminal and how does it relate to the Inhibit Output signal?

The basic purpose of the inhibit circuitry is to shut down the drive and inform other components in the system if a fault is detected. The UMI-7764 has circuitry onboard that will OR together four different sources of inhibits; the per axis controller inhibits, the per axis external inhibits (INHINx), the external inhibit all (INHALL), and the host bus interlock. You can use the INHINx lines to shut down an individual axis or the INHALL line to shut down all axes. These are typically wired to the "fault" output of the drive(s) you are using. When the UMI detects an inhibit from any of the four sources, then it will generate an inhibit signal on the INHOUTx lines. The INHOUTx lines are generally connected to the "enable" inputs on the drive(s). The polarity o
f the INHINx and INHOUTx lines is configurable using the switches on the UMI.
Do not simply tie any of these signals high or low with a jumper. Failure to properly connect the inhibit/enable signals can cause (and has caused) expensive damage to your motion system.

Using a CW230 Bi-polar driver with the UMI-7764 and 7330 PCI. But clock level is loaded below 2v and motor will not run?

I have my stepper driver connected to the +step and aogrnd terminals on the UMI-7764. With the driver connected to these terminals the output across the two is 2vp. When I disconnect the driver, the level returns to a 5vp signal. My drivers inputs are optically isolated so I suspect the impedance my be higher than TTL can drive. Is there any way to manually set the output parameters of the 7330 Motion controller?
Thx...Vic

Hi Vic,
Take a look at this KnowledgeBase: How Do I get the 73xx Controller and UMI-7764 to Drive a Third Party Stepper Motor?
I think it may have the solution to your problem. Also, here is another KnowledgeBase that is relavent:
Why Do I have to Supply Power to my UMI-7764?
I don't believe there is a way to manually set the output parameters of the 7330, but I don't think this is the source of the problem. If the KnowledgeBase articles are not the solution, post back and we'll keep troubleshooting!

Is possible to give a 5V input to the umi 7764 connector blick for the limit switch inputs

I am using a umi7764 connector block for my 7344 controller. My motion control hardware provides me a 5V output in case the limit switches are enabled. But the umi 7764 connector block connections for the limit swithces are in such a way that it doesnt get any input, instead it has to be directly connected to the limit switches.Is there any way to come around this problem so that the limit switch inputs read the 5v given out by my motion control appplcation

If your drive has individual outputs for the forward, reverse, and home switches, then you could connect these to the their respective terminals on the UMI. You will need to either disable limit functionality on one component (controller or drive) or make sure the limit behavior for the devices does not conflict with each other. It probably is best if the controller handles the limits, but this will depend on your application.
If the drive only has one output to indicate that one of the switches has been activated, then you have fewer options. In this case, you should probably just use the limit protection on the drive and poll that single output with another input on the UMI.

My ipad 3 is frozen on the plug into itunes page. I have tried to follow advice I have found on these pages but I don't know how to connect the ipad to my mac (there is no usb port on an ipad). If anyone could help it would be appreciated.

My ipad 3 is frozen on the plug into itunes page - it won't turn off or on - just stuck. I have tried to follow advice I have found on these pages but I don't know how to connect the ipad to my mac (the advice is to connect ipad to mac and there is no usb port on an ipad). If anyone could help it would be appreciated. Going nuts.

I think you should probably also read the iPad User Guide. You didn't say what version of iOS your iPad is running, so here's the links to both the iOS 6 and iOS 7 (PDF) versions:

Contact the University's IT dept, they may be able to set something up on the network to allow the ATV to connect without the need for a user name/password.

Does any body know how to connect the fingerprint scanner using jmf is it p

Hai,
I am not getting how to connect the fingerprint scanner how we can do it is it possible for device independent application
If any body knows anything about this please mail me its very urgent for me
hope u will be able to tell me something about this .
Regards
K Naveen Kumar

Hi,
Fingerprint scanners are not popular enough devices to be supported by Java yet. There's no general API or Java interface for it.
Each manufacturer of a fingerprint device will probably just ship their own drivers or SDKs. More than likely DLL's, so you'd need to write some JNI to call them.
If you want to allow your application to work with multiple devices, you will have to design it to do that. Ie. write a general "Fingerprint" interface, and write a class which implements that interface for each device you want to support.
Eg.
public interface FingerPrintAPI
     public void initialiseScanner ( )
            throws MyScannerException;
     public byte[] getFingerPrint ( )
            throws MyScannerException;
     public double getMatchProbability ( byte[] fingerprint1, byte[] fingerprint2 )
            throws MyScannerException;
     public void closeScanner ( )
            throws MyScannerException;
}I haven't used a fingerprint device at all, but that's how I would approach it.

How to connect the iPad to a TV?

I see that the Netflix app can now output from the iPad.
We would like to show movies on our television. Is the "Apple iPad Dock Connector to VGA Adapter" the accessory to buy? Is there something else we'd need?
We have older TV sets and use RCA component cables to input feeds. (You know, the old red-yellow-white cables.) (That's how our Tivo connects.)
Currently, we connect our MacBook Pro to the TV using Apple's "DVI TO VIDEO ADAPTER KIT-GEN M9267G/A". You just plug a RCA cable into it and run that into the video input jack on the TV. You run another cable from the headphone jack on the MBP to the TV's audio. I realize that connector wouldn't work with an iPad, but what would?
Our sets are standard definition (definitely not HD).

The VGA adaptor delivers the best resolution of the 3 possible "video-out" solutions that Apple offers. Now that both Netflix and Air Video have reved their apps to do video out it seems like the next natural thing is to figure out how to convert the VGA out to an HDMI signal so we can send movies from our iPad to our TVs. There are meny VGA > HDMI converters and I have tried the Atlona VGA to HDMI Scaler/Converter (USB Powered). Model: AT-HDVieW as I saw it mentioned (http://bit.ly/c5U7nv) as a specific match to the iPad. It didn't work. There is no setting on the iPad to send video out rather than display it on its own screen. It switches automatically when it senses "something" attached to the VGA adaptor. This "sensing" works flawlessly when connected to a real VGA monitor but I'm guessing that the Atlona converter is not sending the needed signal back to the iPad to trigger it to dump the video. Will someone please pick up this ball so we can solve this? Other possibilities abound. Here's a few http://bit.ly/d4jgkD and http://bit.ly/asc4RJ THANKS!!

How to Connect the Apogee Duet with Digitech Vocalizer 3

I have been trying to figure out how to interface my guitar and microphone with the Apogee Duet 2 using the Digitech Vocalizer 3 (voice correction). I would like someone from Apple to verify what I have found, but this is how I finally got it to work:
1. Connect you microphone directly to the Vocalizer as shown in the instructions. If you are using a condenser mic, remember to activate the 48v power on the back of the Vocalizer.
2. Set the Vocalizer output to mono (on back of device), and connect one cable from either output port of the Vocalizer to the Input 2 of the Apogee Duet.
3. Use a 1/4" splitter (one mail 1/4" that splits into 2 female 1/4") to attach two standard 1/4" guitar amp cables to the output of your guitar. Connect one of these to the "Guitar In" port on the back panel of the Vocalizer. Connect the other to Input 1 of the Apogee Duet.
4. Open the Apogee Maestro Software, and select "Input". You should see both devices listed (1 and 2). The Apogee will not recognize the Vocalizer as a microphone, so set both of these devices to "Inst".
5. Open Garage Band and add both instruments.
6. When you add your guitar, remember to set your Input Source to "Mono 1" and turn the Monitor On so you can hear it through your hed phones. Also, make sure you have the headphone Icon selected on the Instrument panel.
6. When you add you Vocalizer (Instrument 2), select "Vocals" and "no effects". Remember to set your input source to "Mono 2" and turn your Monitor On so you can hear it through your hed phones. Also, make sure you have the headphone Icon selected on the Instrument panel.
7. If you want to hear and record both instrumental tracks, go the "Track" menu and select "Enable Multi-Track Recordning."
In summary, the Apogee Duet does not appear to recognize the Vocalizer as a microphone, so you have to set up the connection from the Vocalizer to the Duet as another instrument.

#3 Can't you just plug your guitar into the Vocalizer's guitar in jack and then use the guitar thru jack to the apogee?

How to connect the Satellite Pro P100 to Hifi

I've got Satellite Pro P100. How to connect this notebook to HiFI
This is probably easy, but what can i say... just call me stupid.
I've got the lead that goes out of the headphone jack, it links up to my hifi nice.
Trouble being, there's a nasty hiss in the background. Tried plugging my boys mp3 player into the lead, and that works fine.
Any chance of some help... thanks

Hi
In my knowledge you can connect the Sat Pro P100 to HiFi only via a 2-RCA Audio Y cable adapter. In my knowledge the notebook does not support the S/PDIF audio out so you will be able only to use an analog sound port.
You could also buy a stereo adapter with 2x cinch jacks to connect the notebook to the Hifi. Such adapter can be plugged into the headphone jack
Check this:
stereo adapter
I think you should visit the nearest notebook dealer. He can show you the right and supported cables and adapters.

How to use an external start button for 6024E w/ sc-2345, I would like it to function like a start button in LabView but I don't know how to connect the external button to the sc-2345's connector block

I am confused as to how to connect my external start botton. I would like it to function like a start button on a front panel of a VI. I would like to use the +5V on pin 14 but I really don't know where to go from here. Any guidence for a novice would be most appreciated.

phod,
This is the LabVIEW Real-Time forum, so I suggest that in the future that you post this type of question to the Multifunction DAQ forum.
For the simplest solution you will have to connect your button to a digital line of your board, consult the sc-2345 user manual for a diagram of where these lines are exposed. You will have to connect your start button in series with a line that is high, such as your 5V pin or another digital line. Then connect this to a digital line that will be your start trigger.
Your program can poll the digital line that is connected to your button in a while loop and when it goes high, it lets the rest of the program execute. For the programming, I suggest you take a look at the shipping examples that come with LabVIEW. If yo
u have LabVIEW 7.0 go to Help>>Find Examples. Open Hardware Input Output>>Traditional DAQ>>Digital Input and Output>>E Series for some examples of digital I/O programming with E-series boards.
Hope that gets you started.

How to connect the I-Trigue 5600 to a DVD player???

I got a set of I-Trigue 5600 and thinking of connecting all 5 speakers and woofer to the back of DVD player to get the surround effect when watching DVD. The problem is I can just plug all 5 speakers to the back of the DVD player but how can I connect the sub-woofer to the DVD player as there is no cable to connect them together? Is there some sort of cable or adapter I can buy to connect them together? Thx in advance for any help!!!

have you tried that setup already?
my guess is that the subfrequencies are still combined with the front channels, and if I correct, your speakersystem will redirect them to the sub. just give it a try.
