Front Panel LEDs problems for Mega 180

Hi, it's rigth one year I got a Mega 180, and I've not ended yet to tune and optimize it
I admit it's like a hobby now
I immediately ask you for my LEDs problems.
I have read many topics and maybe other people have the same my problem, also if I'm not sure if they treat about the Front Panel LEDs when they speak about the "LCD Display".
I have some switched off LEDs in my front panel, in the "time" displayng and in the volume bar: I have to substituite them? Someone have done it before? It's possible to remove the front panel or I have to disasseble all the pc
Or it's a firmware problem?
I also thank all people that cured the section of optical devices compatibility: last week I bought a new Pioneer 111D, because my LG GSA-4167B was not suitable in the PC mode, for DVD playback.
In fact I had many problems for the DVD fluently playback: I have spent 4 months trying new video codecs and also substituting the video card, then I finally have understood that was an optical device problem.
The Pioneer 111D was perfect in the PC mode, but then I had problems for HI-FI playing mode
Then I finally used my old Pioneer 108, that I had in the old desktop, and all work (I pray) fine both in HI-FI and PC mode.
I'll be very happy also to describe to whom that will ask me, my experience with the Mega 180 "assembling", during the last year, hoping it could be useful for other people.
Thanx

Initially, you might just hook your ring to a case structure to
determine which frame exe
cutes. You can put the terminals for the
Booleans in the different diagrams and about the only other thing to
keep in mind is that you probably want a delay in the loop.

Can I Bind a Front Panel LED to a specific element in an array of booleans?

In LabVIEW 2010 I have a string of LEDs. I have and array of boolean values that contain the values that the LEDs should indicate.
What is the best way to connect the LEDs to elements in the array of booleans?
Can I Bind a Front Panel LED to a specific element in an array of booleans?
How is this done?
Can anyone show sample code?
Solved!
Go to Solution.

Imagine that you have an I/O card that provides 128, 256 or 1024 digital inputs and the requirement is to have an LED on the front panel to represent the state of each digital input. This frequently occurs.
Wiring that many digital inputs individually is a royal pain and then some !
It would make sense to have one shared variable as an array of Booleans that represents the status of all inputs and then use data binding instead of wiring each individually. The individually wiring would violate all recommendations on diagram size and fan out.
Frequently scanned For loops to update all of the LEDS would take alot of CPU time.
Wouldn't it be MUCH better if PSP could be used to update the LEDs whenever the data changed (as it is supposed to do) ?
In my case I have a LabVIEW Yaskawa servo driver that provides me information about 16 servo drives that may be connected. I have LEDs on the front panel to represent some of that status for each individual drive. But Yaskawa provides the information on the drives as an array of clusters of information for each drive, which I perform some business logic on and turn into shared array of Booleans to feed the LEDs (and some banks of switches as well).
Unfortunately LabVIEW does not seem to have any way to bind the LEDs (and Switches) to individual elements in the shared array of Booleans. It is just not that smart. Even with only several banks of 16 LEDs and Switches, wiring them individually using Decimate Array of Index Array functions is a royal pain and makes the block diagrams very large. It would be much worse and almost unreasonable to do if the size of the information was much larger.

Front panel led connectors cables problem

Anyone knows how to connect the cables for the front panel power and hdd switches and leds to the jumpers on the board? The cables have wordings printed on one side of the cables (power led.. hdd led.. etc).. i'm not sure which side should be facing up on the board ... is it the side with the wordings facing up or the opposite side without the printed wordings ? i'm worried that i may end up short circuiting the board if i connec them the wrong way round ... thanks

The are just switches, so there is no polarity to worry about. the led's are polarity sensitive, so If they don't work, just reverse the connection; no damage will occur.

Controlling Front Panel LEDs

This is hopefully a simple problem, but I can't figure out what to search under. I have a program with two loops (Z Only Test and Full Test in Tester Program v2). They do not run at the same time. I would like both loops to interact with an LED on the front panel (Testing). How is this done?
Under Z Only Test, it works fine. I tried to connect it to the sequence (Full Test), but it tells me I can't do that. On odd sequences, for the most part, I would like to have the LED light (TRUE). On evens, off.

Do you mean make the LED a shared variable? How do you do that? I clicked on it and changed it to a variable, but I thought that was like one of the others that I have. I'll give it a try and see what happens.
I would assume whatever works for this would also work for numerical displays as well.
No. I'm not even sure exactly what you mean by clicked on the LED "and changed it to a variable."
Right now you have only a single place where you use that LED. It has a terminal node on your block diagram within a while loop. I don't know how that fits into your overall program architecture as your VI is quite expansive. (Two tips, 1. Don't use stacked sequences. 2. Look into a state machine architecture)
All that happens at that point is your read from a shared variable called "Testing". I'm not sure from where else in your VI that you want to interact with that front panel indicator. Or whether it will conflict with the already written piece of code. I also don't know where this shared variable is written to. But the first idea is have the other sections of the code write to the shared variable and let this one update the front panel indicator.
The second idea is to create a local variable of the front panel indicator. Right click on the terminal within your code and select Create / Local Variable. But again, you will have to be careful with conflicts with the different portions of your code writing to the LED. This is also known as a "race condition".
(Yes you can use either shared variables to store numeric data, or create local variables of numeric controls or indicators.)
I'm a bit nervous about your code. It looks like you have a decent amount of LV experience as you have created quite a sophisticated VI there. However, it doesn't seem like it is easy to expand or modify. It takes up quite a bit of screen real estate. It doesn't use any subVI's even though a lot of the code seems to be duplicated or very similar. And it seems like it uses a lot of shared variables, probably more than necessary.

Save a front panel image problem

Hi, i'm trying to save at run-time an image of my front panel, and the little code with the Invoke Node (FP.GetImage) works well but there is a problem, i have a background image for my front panel and this image don't show up in the image saved so i have an image with controls and graphs but a blank background. Is there some way to obtain an image of my ENTIRE front panel? Thanks

Hi,
Here's how I got ride of tghis issue, I use Windows "printscreen" function by simulating a keyboard stroke and then I get the data from clipboard (crop it it necessary) and save the image.
What I like about it is that the "crop" makes it easy to get just what I want when there's more than one monitor.
What I don't like is that it's a windows only solution.
Hope it helps

Accessing front panel LEDs in several subVIs

Hi, I'm new to LabVIEW! Ok, what I'm trying to do is create a front panel with 9 LEDs. Then I have a Menu Ring, with three different options. These options determine the order in which the LEDs are lit. So what I was planning on doing was creating three subVIs, one for each of the options...but how can I do that when I only have one boolean for each LED? So basically how can I relate the LEDs on the front panel into the subVIs? I tried using globals - but it seemed like that just passed on the state of the boolean instead of allowing me to actually change the boolean in the subVI. I hope this makes sense...I'm really confused! Thanks for any help!

NI 5112 Scope soft front panel setting problem

Hi,
I tried to meausre a 5.1 voltage using SCOPE soft front panel. I could get 5.1 AC voltage from SCOPE soft front panel,
but it did not go back to 0 volt after 1 to 2 second in a horizontal line. Nornamlly, my 5,1V will go back to 0 volts
in my oscilloscope after 1 to 2 seconds because I am measureing a shock beep pulse waveform.
Can you tell why?
I am going to give you my setting. I was trying Y-axis 2 volt/div, AC coupe, ch 0, X-axis is 10 microsecond/div. normal mode.
Trigger: edge, rising, ch 0, trigger lever 2.5.
I am in a urgent. Coould you pls send me quickly

I'm sorry if I don't completely understand what the behavior is but if I understand you correctly, you have a signal that goes from 1 volt, peaks at 5.1, and then slowly drops to 1 volt again. That entire signal takes 1 to 2 seconds.
I am not sure if the problem you are seeing is 1. You can never get the full signal in the SFP or 2. You get the signal ok but the SFP does not wait for you to hit a button to try and acquire again.
If the question is number 1
If this is the issue it sounds like you are able to capture the 5 Volt peak, however it never goes back down to 1 volt. You mentioned that you have the X-Axis set to 10 microseconds/ div. Therefore the SFP is only acquiring an total of 100 microseconds, and if the reference is set to 50%, then you are only getting 50 microseconds of signal after the trigger, so you will not be able to acquire the 1-2 seconds it takes for your signal to drop. I would suggest increasing the number of points and slowing down the Time/Division. You should be able to change those settings a few times to actually get 2 seconds worth of signal.
2. If you want to simply hit a button and the SFP will acquire again then you need to change the mode to SGL. Then you just need to hit the run or pause button and the SFP will acquire again.

Remote front panel reconnection problem

Hello,
I have created a real time application build for myRIO and i can succesfully run it as startup. After MyRIO reboots, through the Project Window i select Operate/Connect to Remote Panel. I enter the local network IP address 192.168.0.101 and port 8000 and the Front Panel of the Startup VI opens. I run it and everything is running as expected.
This setup is installed on a UAV and acquires data from scientific instruments all data is writen on a USB flash drive on myRIO
It is expected that sometimes the local network link will break during the flight. To simulate this i unplugged myRIO from the ethernet cable will the Data is saved.
I noticed the following strange things:
1. At time X i connect to the remote panel and i start the DAQ which acquires data
2. At time X+10 minutes i unplug the ethernet cable which connects myrio to the local network
3. At time X+20 minutes i poweroff myRIO
I was expecting that after the connection was broken the VI would have kept acquiring the Data until myRIO powers off.
Instead i noticed that myrio acquires data for only 1 more minute after the ethernet cable is unplugged.
It is very important that after the UAV takes off whatever happens to the network connection the VI keeps acquiring data for as long myrio is powered on.
I also tried the web publishing tool but i could not connect using a browser. It seems that the web server was not running properly. I also noticed that the html file was not located in the target destination folder. I tried to manually copy it using a map networked drive but the file could not be copied.
I will appreciate any help on the above issues.
Thank you,
Christos

I see thank you. Very funny because i thought i had to do something with duplicating the real time target.
So regarding the above problem, is there any way to be connected remotely to the target and when the link is broken to reconnect without affecting the operation of the VI running?
For example, lets assume we connect to a remote front panel which has a simple VI with just a 1 second period timed loop running and for each iteration of the loop i monitor and i save the index of the loop. When i connect to the VI i request control and i click run. The VI starts running. After one minute, at loop iteration 60 the link between the host and the target breaks. The VI should continue running.
After 1 minute of broken link the network is again available.
What can i do to re-establish connection without affecting the VI operation and continue monitoring the VI. If reconnecting after 1 minute i will be expecting to see the loop iteration to be 120 and keep running. Is there any way to do this?

Z87-G43 Board Front panel USB Problem

I have installed the board and windows 7 64bit
Updated the Bios and checked everything I could. I do NOT get the connect tones from anything I connect to the front panel USB ports. I have used 2 (KNOWN GOOD, works on other machines) connector sets with 2 ports each, and ALL of the ports have the same symptoms. All of the usb devices have the connect tones when inserted to any of the rear ports. I have not tried the USB3 port for the front because I do not have the wiring and related header connector. My phone, (Samsung GS4) when connected to the rear ports always opens an explorer window showing the Ext SDCard and the Internal memory. when I connect to any of the front panel ports, no sound, no pop-up of explorer, but I do see the device when I manually open explorer and can open the connection manually.
I am at a loss as to what is not right and how I can make it work correctly. If anyone can give me any information to correct this, I'd be very grateful. (Tech Support was no help)
Thank you, and Aloha From Hawaii!

Thank you for your reply.
I have an older Antec Case and I have tried a brand new front panel connector I got from Frys and it acts the same Way. the only difference is that the connector is a one piece assembly that connects directly to the mobo header pins. the one in the case has individual pin connectors. both systems end up with the same scenario. When I plug in a thumb drive, there is no connect or disconnect sound and I still can manually open explorer and access the thumb drive or my phone but nothing pops up to signify any port access.BTW, I am a systems engineer and have spent the last 13 years building machines for a transportation company (bus) My previous board in the same case used the front panel connection and it worked just fine, but since the board died and was only supportive of XP I decided to upgrade to Win 7 64bit and have 16gb ram. All the rear connectors work just fine, but I need all of them so have to use the front panel connection for phone, and thumb drive access. I suspect the mobo has a design problem. The tech support person had no suggestion to correct this problem too! :<(

K8N Neo Platinum + Sonata Front Panel Audio Problem

Hello,
The front panel audio speaker output is reversed when using headphones on my K8N Neo Platinum and Antec Sonata case. If I swap the left and right front panel audio output signal connectors, the headphone speakers are fine, but then my normal front speakers are reversed. All other connectors seem to be plugged in correctly. I've tried using nvswap, but doesn't seem to work on nForce3. Currently using Realtek driver version 5.10.0.5620 (had the same problem with the drivers included on mb cd) on WinXP Pro SP1 and 5.1 speaker setup (would like to use FPA for mic/headphones while gaming).
Let me know if you need any additional info.
Thanks.

I am having the same problem as well. Was able to correct front output jack by switching the connections. But rear audio is still backwards. I havent tried any sort of 5.1 or 7.1 channel audio setups

MSI K9A2-CF front panel audio problem

Just rebuilt a computer using the board. Please note, I have not updated the BIOS at all and I am using XP Pro. Anywho, I've tried everything under the sun, so far, aside from previously stated, to get this sucker to work. I have it connected properly, I've installed every audio driver on the motherboard CD. I can't find a setting in the BIOS to turn on front panel audio either. Everything else works fine though. USB's, HD audio connections in the back, etc. The program in windows will detect all inputs except for the front audio in and out.
I'm a bit stumped. Any suggestions?

Quote from: Bas on 17-August-09, 22:22:14
You have to check the wires on the plug, looks like they are wrong or the case-module is broken somewhere.
You have to start checking and measuring with an Ohm-meter.
Remember, neither case front worked. I'm not saying it couldn't be the case, but I'll try to get my hands on an Ohm-meter. Where can I find out what values I'm looking for? I know next to nothing about testing to that extent.
Also, what if it's the motherboard itself? Isn't there somewhere in the bios and/or windows device manager that I can confirm whether or not the device itself is working, or not working, properly?
Thanks for your replies so far.
Mike,
I honestly don't know, but the case only has one audio cable, and the MB only has one audio plug-in for the front panel. I have both drivers installed. The on-board audio plug-in on the rear of the computer works fine. I can get sound, etc, no problem from the rear. Front panel only is not working.

Cd rom boot problems with MEGA 180

I recently recieved my MEGA 180 and have been unable to successfully install an OS because when I boot from CD, the computer freezes at various stages of installation. The point at which it freezes varies between the point at which the CD is initialized to anywhere in the windows xp setup process up untill the drive format. Occassionally the lockup coincides with an error copying a file, but this is not consistent. I have tried two different cd-rom drives as well as three different xp installation cds. Further I have run with 5 different sticks of ram (kingston and corsair). None of these changes have had any obvious effect.
Having read the warning labes regarding non MSI optical devices, I am tempted to think that may be the problem as I am not running on an MSI drive. However, the warning souned like it was about mechanical parts and thus I assume the ability of a drive to fit in the MEGA 180 case while opening and closing correctly.
I would appreciate any input you might have on this matter as I am finding this experience rather frustrating.

I had the exact same problem when upgrading from a 2100+ Palamino processor to a 2800+ Thoroghbred one. The screen had already dissappeared due to powering up with no monitor plugged in, so I tried a reinstall of Windows XP. It kept falling over randomly during the install process. I then swapper the CPU back and had no problems at all. I have since lapped the heatsink and reduced the FSB to 157MHz in the BIOS, and have not had a problem with the 2800+ CPU. I have not tried installing windows again, but feel this will be OK too.
My test is to run FujiFilm Snapshot Slideshow, which sends the CPU temp rocketting. I have found that when it goes above 70 C it starts getting unstable. I throttled the FSB back to 157MHz and it does not get to 70 C any more. In normal operation it never gets above 60 C, so I don't know why the slideshow takes so much CPU power

Advice needed for buying an AGP card for MEGA 180

Since 1 year I have a MEGA 180 with a SEMPRON 2500 processor, 512 MB DDR RAM, Lite-On DVD-R/W, Hauppauge PVR-150 running MediaPortal 2.0.0.0.-RC4 and it rocks!
I am not so happy though about the TV-output of the integrated GF4MX that came with the nForce2 chipset. I would like to disable this and insert a low profile, passive cooled nVidia-6200 with 128 MB-DDR. I am a bit worried about the power requirements of the card and the juice that the power supply (200W ) can deliver. Is it safe to use this card or should I adjust my demands? I am using the system for media purposes only, e.g. recording and watching recorded TV, watching movies and playing music. MediaPortal requires a DirectX-9 compliant card, DirectX-8 also works but with video artefacts. Gaming is no requirement.
Can anyone please advice what to do ???
Thanks in advance, Leo

FRONT PANEL AUDIO PROBLEM

Ok i have a Hp pavillion m7480n and yesterday i bought a new graphic card (Nvidia geforce gt220) so i installed the card correctly and everything went well. When i restarted my pc the sound in the taskbar said something about HD. The graphic card has a HDMI out so i guess that after installing the card, the audio went to default HD wich i really didnt want to cuz i do not have a hd monitor.
then i downloaded, reinstalled, uninstalled, reboot, installed again the realtek hd audio driver cuz thats what i thought it was but nothing worked ! so now if i want to use my mic i have to plug in the device at the back of my pc wich is really annoying cuz i change alot.
i really tried everything from going to the bios setup to enable "onboard audio", reinstalling drivers, realtek sound manager options "mute rear output device, when a front headphone plugged in." "enable jack detection when device is plugged in".... so i dont know what else i can do about it... really need help ! and by the way i noticed that on my realtek HD audio manager the "Front panel" is grayed i cant click on both of the inputs heres a link to the screenshot
http://img267.imageshack.us/img267/9473/picyy.jpg
and on this screenshot i there is some level (green bars) on the mic but beleive me its not working.
i beleive that theres a possibility that a wire disconnected when i installed my graphic card but i want to be sure its not a simple driver problem or whatever else before playing with the wires inside.

had the same issue, its the graphics card since it has an integrated HD audio, it causes a conflict, what you have to do is restart the PC, hit either F1 or F10 to go to setup, then go to where it says sound, and you have to change it to onboard device
after that both should work

Front Panel USB3 solution for 990FXA-GD65?

I just got a 990FXA-GD65 and a case with front panel USB3. I assumed (incorrectly) that there would be a USB3 header on the MB. Is there any way to hook up the front panel USB3 male plug (20-pin I believe) to one of the back panel USB ports with some kind of adapter?
Thanks.

Yes they make those adapters and they make adapters for plugging those ports into the USB header on the motherboard. Then you can always put an add on card for USB3 connection.

Z87-G43 : JAUD1 front panel connector problem

Hi everyone,
I received this mb two days ago, everything was working fine until i decided to plug my headphones in the front panel jack of my Zalman Z12 plus...
There is like an "underwater" effect that makes the sound pretty bad. The rear jacks work flawlessly.
Any clues ? Any feedbacks ?
I've tried to :
- reinstall the latest realtek driver : still
- use another headset : still
Maybe the mb is faulty, maybe the case is...
Thanks.

Quote from: Ppgtjmad on 08-February-14, 20:42:32
Hello,
Thanks for the feedback. I found the culprit : broken front panel audio connectors on my Zalman Z12 Plus.
What case do you have ?
Glad to hear that you figured it out.
