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.

Problem with front panel USB connector

Motherboard: MS-6750
I have a problem with my front panel USB connector JUSB2 not working.
I have checked the connection to be sure that it is oriented correctly.
I also made sure that it was enabled in the BIOS.
Still no luck. There is not any voltage on this either.
I see a jumper or pin labeled JGS1 just below the JDLED1...do not know what this is and cannot find it in the manual.
Any ideas on what this is and how I might trouble shoot the USB connector?

Which 6570 MB do you have, if its the K7N2 Delta 2 Platinum and came with the Dled bracket try plugging that into that port on the mainboard and see if those usb ports work as it could be the usb hub itself not working on the front. Hope this helps Dok

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.

~~KT4V~~ Front Panel Pin Connectors (USB + Audio)

Hello All
I have a few questions on setting up the front panel pin connectors from my case to my new KT4V board.
First question: USB
My case is usb 2.0 (Raidmax Scorpio)it has two seperate pin connectors a 4 pin and a 4 pin + GND pin on the second wire. I assume I put the GND in the JUSB1 #10 slot which is marked (USBOC) in my manual. Is this correct?
Second Question: Front Audio (Microphone, Headphones)
The front panel Audio Connector: JAUD1
The four pin connectors that my case has labeled is:
1. MIC DATA
2. MIC GND
3. EAR R
4. EAR L
I am pretty sure MIC DATA goes in pin #1, and MIC GND goes in pin #2. As far as both EAR pins, I am not sure and would appreciate some help in this.
Thanks in advance.
ncarme :D

I know, I have the book in front of me. But the names on the board and my case are different. Thanks for the info on the usb, how about the audio inputs.
Thanks.

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.

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!

MS6117 Front Panel Pin Connectors

Can anyone help me? I have a old MS6117 MOBO and I need to connect the front panel connectors. I looked for a manual but could not find one. I know where the pins are located in the board but no idea which are the pwr switch pins etc. (The MOBO has no markings as to what pins to use for what) . Thankyou

Hello! Welcome to the forum!

About Front Panel Audio Connector: JAUD1

In the User Manual for the K9N6PGM2 nVIDIA chipset mainboard, you are advised that pins 5, 6, 9 & 10 must be jumpered if you do not want to use the front panel audio but you want to use the back panel Line-Out instead, otherwise it won't function.
My question is (sorry if this is a silly question, only I'm new to building PC's ), if you want to use both the front and back panel audio slots, as I do for my current system that I want to replace, will the Line-Out at the back work automatically (i.e. connecting up the front panel audio is enough), or do you have to set something else in addition.

Of course, silly me Thanks for clearing that up

32AV502U Front Panel LED Flashing, No Video/Audio

We had a short power outage last night and ever since my 32AV502U set will not turn on. Instead the power LED just flashes on and off in a patter of long, short, short. I have tried leaving it unplugged for hours and still no luck. I held the power button down while it was unplugged too, but couldn't get it to do anything other than just have the LED flash.
I was wondering if anyone knew of a way to fix this.
Thanks

I've got the same issue. I found this TV at the electronics recycling area of my local landfill, so I have nothing invested in it so far, except a bit of research time. I tried calling Toshiba Customer Service to see if they would tell me what the long short short flashing light means, but since it's out of warranty, they wanted to charge me $35 to answer the question. It looks like someone tried working on it already. I got Toshiba's Service Material and reference Tips document for this TV, and followed the section for Dead Set on page 5. I do get the standby 5 volts on the P802 connector, but following the flowchart to the next step, I do not get 4.3 volts on pin 13 when the on/off button is pressed. The next step at pin 14 showing less than .07V also fails. That results in a "Suspect a problem with the power supply module. There's no further module level troubleshooting that I could find.
None of the capacitors are bulging, so that takes away an easy check. There hasn't been much in the way of component level troubleshooting that I could find.

How do I derive front panel led's from kstat?

/* compile with cc enclosure.c -lkstat */
#include <stdio.h>
#include <stdlib.h>
#include <kstat.h>
#include </usr/platform/sun4u/include/sys/envctrl.h>
main()
kstat_ctl_t*kc;
kstat_t *kp;
envctrl_encl_t *enc_info;
int i;
/* initialize the kstat interface */
kc = kstat_open();
if (kc == 0) {
perror("kstat_open");
exit(1);
/* find the inode cache link */
kp = kstat_lookup(kc, "envctrl", 0, "envctrl_enclosure");
if (kp == 0) {
fputs("Cannot find envctrl.0.envctrl_enclosure\n", stderr);
exit(1);
/* read the ks_data */
if (kstat_read(kc, kp, 0) == -1) {
perror("kstat_read");
exit(1);
printf("there are %d instances\n",kp->ks_ndata);
enc_info = (envctrl_encl_t *) kp->ks_data;
for (i=0; i < kp->ks_ndata; i++){
printf("loop value : %d\n",i);
printf("instance : %d\n", enc_info->instance);
printf("enclosure type : %d \n", enc_info->type);
printf("enclosure value : %d \n",enc_info->value);
printf("********************\n");
enc_info++;
kstat_close(kc);
return 0;
Returns...
There are 7 instances
enclosure value : 208
or
enclosure value : 192
depending whether one of the lights is flashing or not. I need to know how to tell if an error light is on.
How about the disk led's?

You don't actually need to pass anything to the Sub-VI.
Within the Sub-VI you can call up the chain of "higher" VIs, i.e. the VI call chain leading to the sub-VI in question being called. From here you can wire simply the text of the VI you require to an "Open VI reference" function, get a list of the controls or indicators and initialise them as you wish. I used this a few times for a custom "Print Parent Panel" VI.
Here's a pic of an example (LV 6.1)
Hope this helps

Front panel firewire/USB connection problems

I've connected all the wires from the front of my case to the appropriate slots on my mobo (K8N Neo Platinum), but none of them seem to be working. I rechecked the firewire pin positions, but to no avail. Maybe the wires are incorrectly labeled? I don't know what else to do.
thx

Check your pinouts. Apparently, Antec is one case manufacturer that includes an "extra" ground pin which can cause USB ports to fail (not recognized, intermittently recognized, causing the D-bracket to fail, all kinds of mischief).
I'll check it out later this evening and post the results.

This link says that grey is an USB+ and blue is a GND wire, yet they were switched in my connector, blue at the USB+ pin and grey at the GND pin... so I switched them back.. checking how they work first with a little something that only takes the power from the usb ports so I won't screw up something in them

MCS 7845-H2 Front Panel LED's

Trying to find some sort of support document for this server model to get an understanding of what the LED's mean, as one of them has just turned amber (which according to this ( http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/product_data_sheet0900aecd80572766.html ) it indicates an internal component failure.

There's no setting to adjust the brightness of the LED.
Next time you are near an office supply store, pick up a box of 3/8" or1/2" round, white labels/stickers.
Place one or two over the LED and it will dim the LED. Add more to adjust the brightness level you want.
The white stickers are virtually invisible once you move back 3-4 feet from the AirPort Extreme.
Looks much nicer than a piece of tape.

The VXI-1394/G front panel GPIB connector is supported under WindowsNT4.

Does it been supproted under Windows2000?

IEEE-1394 is not native to Windows NT. Because of this, there are a few 3rd party 1394 device drivers for Windows NT out there. However, there are frequently issues that arise because Windows NT does not support 1394. The NI-VXI driver included a 3rd party PCI-1394 driver to allow the VXI-1394 to be used under Windows NT.
Currently, the only NI-488.2 driver that supports the GPIB port on the VXI-1394/G is for Windows NT. R&D has considered making the investment of developing a new version of NI-488.2 that will support Windows 2000. However, I do not believe a decision has been made at this time. Since a PC is already a part of your system solution, we recommend using a PCI-GPIB card installed in the PC. There are also other GPIB so
lutions, such as the GPIB-ENET and GPIB-USB.
