Distortion with dual 2ghz optical input using external instr

I am using the external instr. feature in logic to input a synth via the optical in on my G5 dual 2ghz. I get really distored recording from this. is this a known problem? i think i read somewhere that the optical ports on the G5 have problems with distortion.

no in principle there should be no problem. i use the optical i/o on a G5 dual 2 gig all the time, distortion has never happened. it's more likely that there's a problem with sample rates or sample sync going on.. how exactly are you connected? directly from the synth? if so, what kind of digital output does it generate? also check in audio midi setup that your sample rate matches up with what the synth is outputing.

How do I count parts with a fiber optic sensor using the NI-1772 and VBAI 2011?

I'm inspecting parts using the NI-1772. Just after the camera, bad parts are ejected when they pass by a fiberoptic sensor. I want to use another sensor after that to verify the number of good parts, so that I can be sure the bad parts have been ejected?
I've tried using the READ/WRITE I/O step to read falling edges in sequence with a calculator step to increment the counts for each inspection iteration. I get a few counts at start up, and then the counts stop. It's as if the inspection has looped back to the Acquire Image step before or after the cap is present at the sensor.
Once this is figured out, I want to reset the count when a preset is reached.
Thanks,
Rob

Hi Brad,
It seems that the ISO Input is reading all of the falling and rising edges based on the LED, and that the Read/Write I/O step counts all of the falling edges when in configuration mode. I believe the signal stays low for about 10ms. (It might be important to clarify that I'm not using the camera trigger input for this. It is a subsequent sensor downstream of the camera.) I've attempted to attach a section of my inspection.
Thanks,
Rob

What is "best practice" to set up and configure a Mac Mini server with dual 1 TB drives, using RAID 1?

I have been handed a new, out of the box, Mac Mini server. Has two 1 TB drives in it. Contractor suggested RAID 1 for the set up. I have done some research
and found out that in creating the software RAID, this takes away the recovery partition, so I have been reading up on how to create a recovery "disk" using a thumb drive. this part of the operation I am comfortable with, but there are other issues/concerns that I have.
Basically, what is the "best practice" to setup the Mini, configure the RAID and then start the server. I am assuming the steps would be something like this:
1) start up the Mini and run through the normal Maverick setup/config - keep it plain and vanilla
2) grab a copy of the Server app and store it offline in a safe place
3) perform the RAID configuration / reinstall of OS X Maverick using the recovery tools
4) copy down and start the server app
This might be considered a very simplified version of this article (http://support.apple.com/kb/HT4886 - Mac mini server (Late 2012 and Mid 2011): How to install OS X Server on a software RAID volume), with the biggest difference being I grab a copy of the Server App off of the mini before I reinstall, since I did not purchase it from the App store, but rather it came with the mini.
Is there a best practice / how-to tutorial somewhere that I can follow/learn from? Am I on the right track or headed for a train wreck?
thanks in advance

I think this article will answer your question. Hope this helps: http://wisebyte.blogspot.com/2014/01/best-configuration-for-mac-mini-server.html

How to generate a pulse of 5 V -ve polarity in synchronisation with a 10 v input using PCI 6251 DAQ board

HI
I want to generate a 5V -ve polarity pulse to trigger my IEEE 1394 camera using an PCI 6251 (scb68 pin E) device, furthermore I am reading a standard Vsync signal from a SVGA port which is 10 v.
Now I want to synchronise the image capture of an IEEE 1394 camera with the Vsync signal so that camera is triggered to capture at every 4th Vsync signal (which is 50HZ.). Presently I am able to read the Vsync signal and also generate the -5 v signal But the Daq board generates a continues -5v signal while I want a 1 ms pulse (for every 4th Vsync).
Also this 5 v signal is generated even if the vi is stopped running.
Can anybody guide me so this problem can be solved.
Thanks a lot in advance
Shri

You can use the Write function, that is you can use the 10 volt signal as a trigger for the task, and when you get this trigger, the task starts and generate (writes) a waveform you defined in an array ("data", in the example).
Something like this..
DAQmxCreateTask("",&taskHandle);
DAQmxCreateAOVoltageChan (taskHandle, clokSource, your_sampling_freq, -10.0, 10.0,
DAQmx_Val_Volts, "");
DAQmxCfgSampClkTiming (taskHandle, clockSource, SAMPLING_RATE,
DAQmx_Val_Rising, DAQmx_Val_FiniteSamps,
samp_to_read);
DAQmxCfgAnlgEdgeStartTrig (taskHandle, input_channel, DAQmx_Val_RisingSlope, 9.0);
DAQmxWriteAnalogF64 (taskHandle, 1000, 0, 10.0,
DAQmx_Val_GroupByChannel, data, //data contain a pulse
&samp_per_channel, 0);
DAQmxStartTask(taskHandle);
// and then you create a loop....
For example you can specify data to be like this:
data[0] = -5;
for(i=1;i<1000; i++){
data[i] = 0;
Tell me if you need more help.....

Current uses for a G5 PowerPC dual 2GHz

Hi guys. I just undercovered an old silver G5, think it has 10.4 or 10.5 on it, with dual 2GHz PowerPC processors in it. I know it's real old and can't really do much, but what would be some practical things I could use it for in a business environment. Would it run a USB scanner? Or what else can you think of? Hate to just let it rust up sitting in storage.

Hello,
I use a G5 as my main computer at work still.
If the Scanner doesn't have drivers for your OSX version there's always VueScan...

TenFourFox is the most up to date browser for our PPCs, they even have G4 & G5 optimized versions...

G5 dual 2GHz wont see external 4Tb

Can anyone confirm how to get G5 dual 2GHz to recognise an external larger than 2Tb. Was thinking of Sonnet range - Tempo SATA E2P card?
Thanks

Yes, it will recognise externals apart from anything over 2Tb capacity.
Thanks

Using EXTERNAL INSTRUMENT plug normally has latency BUT NOW FULLY SOLVED ???

Hi,
I use alot of outboard synths and I use the EXTERNAL INSTRUMENT plug from Logic9 for this.As MIDI destination I choose my synth (Elektron Monomachine) and as AUDIO INPUT 11-12 , nothing spectacular there.
When I play this external instrument in Logic by hand using my usb controller keyboard everything plays in sync,but when I record it it has latency...Again this is normal (I think??) because I browsed alot of Logic groups and came to the conclusion that the EXTERNAL INSTRUMENT-plug isn't delay compensated,am I right? Even after rigid quantizing the recorded midi sounds a bit late,sluggish.
So the recorded midi has a delay,but THEN I FOUND OUT THIS : If instead in the EXTERNAL INSTRUMENT-plug I choose GM-device (don't know how this got in my midi destination list) instead of Elektron Monomachine as MIDI destination the midi is SPOT ON !!!! (playback)
Can somebody clarify this,this is very strange....the only downside to this is the fact that when I use the GM-device the midi is send to all my midi-synths at the same time....But what the heck,if I can record without almost no latency :-)
What am I missing,I feel like an idiot :-)

I've always used External MIDI tracks to control outboard instruments - it used to work perfectly for me, mostly using an Akai Z8 sampler and various synth modules. I'm becoming more inclined to doing everything in my computer though, these days.
The I/O plug-in has a Ping function - in other word, its sends a small packet of data to your external device and measures the amount of time it takes to come back, if you've got connections going both ways - I haven't used it, but I suppose that may help you with the latency problem, but using external MIDI tracks gives you all the basic stuff you want to do.

I use a 2003 FW800 MDD desktop, with dual 1.25 GHz processors, and OS10.4.11, and with native Bluetooth card, won't recognize a newer Bluetooth Headphone set as an Input or Output device in System Preferences

I use a Mac 2003 FW800 MDD desktop with dual 1.25 GHz processors, 2 GB memory, and a native Bluetooth card installed. I use OS10.4.11. The FW800 was the only MDD that could use Bluetooth natively, as an optional installation. I use the installed Bluetooth to run an Apple Aluminum Keyboard, and would like to use it with a new (2010) Samsung SBH-600 Bluetooth Headphone set, but, although the set will pair with the computer, and is recognized in both the System Profiler, and the Bluetooth section of System Preferences, it is not recognized in the Sound preferences section of System Preferences as either an Input or Output device. Only the installed external Apple speakers are recognized. I'd like to know if there is anything that can be done to make the Bluetooth system installed work with these headphones - either something that can be changed in the computer settings, or an added external Bluetooth device with different Bluetooth capabilities.

It it may be that you are running either an outdated BT software or the firmware of the card is not up to date.
What version is your BT software? Is it later than 1.5?
http://support.apple.com/kb/DL1209
Firmware:
http://support.apple.com/kb/DL354
Along with the firmware, it is likely that the headphones require a later BT revision than you are running. The headphones need rev.2.
You may need to move to Leopard for support.
http://support.apple.com/kb/DL889
It also may be that headphone support is limited to iChat or the like in Tiger.....
If you go to a USB BT dongle, D-Link often gets the nod as having native compatibility in OS X.

Starting and stopping timer using external inputs interfaced with labview

hello,
I have trouble finding how to start and stop the timer using external voltage or current pulse. we are interfacing a circuit to labview. so for that we need to count the time it takes between the two external voltages. We have to keep on comparing the voltages to some reference voltage. And when the external voltage crosses the reference voltage we have to start the timer and again we have to stop the timer using tha same logic. We need it for time calculation between the triggers.
hope you can help.

https://decibel.ni.com/content/docs/DOC-23334 is agood example to start. You need to modify it to include stop trigger.

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?
I use a Mini as the family media center and would like to have 5.1 or 7.1 sound for films but don't want a huge piece of eletronic equipment (I have one of those, but it isn't hooked up because it doesn't fit on the bookshelf). Years ago I used a PC and still use the Creative Audigy speaker system (Jimmy rigged to the Mini) that I ran from the PC. The Audigy PCI sound card obviously doesn't work on the Mini, so I just have two chanel plus sub. That has been fine since I switched to the Mini in 2007, but am updating to a new Mini in the summer and would like to upgrade my sound as well.
I also wouldn't be opposed to a USB soundcard that can drive the speakers. In fact, my wife would prefer smaller and less visible, ergo USB card hidden in the back.
Suggestions?

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

Welcome to the Apple Community.
Are you sure the content you are playing has Dolby Digital.

How do I use optical input for recording in Garageband 9?

Hi,
I'm trying to use the Optical Line Input on my G5 for recording in Garageband, using a MOTU 828. I have the 828 optical output connected to the optical audio input on the G5, and I have Digital In (Optical digital-in port) selected in system preferences/sound. But in Garageband preferences, optical or digital input is not among my choices. If I select system setting or built-in audio 2, I get no signal. If I select MOTU 828, it defaults to the analog master outputs on the 828.
I am a Logic 8 user, and I'm able to select the optical input in Logic with no problem. I have my MOTU audio setup set so that the optical output is the default output, but Garageband still seems to use the analog output. I can tell by the record level, which is considerably louder for analog than for optical.
Any suggestions?
Thanks!

Burn in itunes using external optical drive imac 2009

My Matsushita optical drive (2009 iMac) no longer works. Is there an external optical drive that I can purchase for burning music CD's?. I already have Maverick, but I believe the operating system is not the problem. The external optical drive has to be compatible with hardware that already has an internal (non-functioning) drive.

I have a PIONEER DVD-RW DVR-XD09.
It's worked on systems with or without optical drives for me since 2009.
It was $69 at Bestbuy.
It has a USB/Power combo cable that uses TWO USB ports, but I got a 5v AC adapter for $4.99 and now it only needs one USB port to function. I've burned with it under 10.8.4, 10.8.5 and 10.9.0.
They've upgraded it since I got mine (Link here) so it can burn Blu-Ray now

Use of business partner functionality in combination with dual control

Is there a generally agreed upon procedure to use the business partner functionality in combination with dual control? The problem is that when you block a business partner, the customer/ vendor master data aren't blocked automatically. You can then still use them in transactions, which leads to problems.
So is there a way to make this work or a procedure to do this?
Niels Vanwingh

Thanks Masa,
I did notice the 'Add external supplier from' in create supplier or bidder option. However there is a small catch and your experience may help.
Let me explain the requirement and scenario here in SRM 7.
We are implementing the Registration of Supplier scenario; both ROS and SRM are in same client. When a potential supplier registers themselves in the registration system, a BP number is created (an Internal number range is defined for this). After accepting the potential supplier in pre-select screen the purchaser has two options to transfer the potential supplier from the ROS system to SRM
Option 1: He can select the accepted potential supplier from the supplier directory option and transfer the business partner to SRM. In this case the business partner number of the potential supplier is retained in SRM and a business partner with supplier and bidder tag is created. However the purchaser does not have any option to select which type of business partner he would like to create like supplier or bidder.
Option 2: Purchase can go to create supplier or bidder option and choose the u2018Add external supplier formu2019 from the ROS system and create the business partner. The ROS business partner details are copied to the create supplier screen, but the purchaser have to provide an external business partner number for the supplier. This is because we have defined external number range for business partner for the vendors that are replicated from ERP to SRM.
Objective is the ROS business partner should be retained in SRM with option to create as supplier and bidder and then manually create ERP supplier with same SRM BP number and map against SRM supplier.
Is there any way we can achieve this?
In SRM 5.5 with Manage business partner functionality we could achieve as system give us the option which business partner type we would like to create as well as retains the ROS BP number in SRM.
Regards
Sandeep

Full backup ( ~ 1 TB ) using external HD - speed USB vs. Firewire vs. eSATA - what are relative speeds - how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)_

    Hi All,
     I'm trying to resume regular scheduled Full backup ( ~ 1 TB ) of drives using external HD (to allow off-site redundant backup storage) .
     What are relative speeds of USB vs. Firewire vs. eSATA ?
     I suspect eSATA connection may be considerably faster … how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)?
      ( The quicker and easier backup protocol is, the more likely one is to use it to backup on a routine repetitive basis.)
Thanks

Adding a USB 3.0+eSATA PCIe card, which The hatter mentions, is the best solution that I've found. See http://eshop.macsales.com/item/CalDigit/FASTA6GU3/. The card is not cheap, but the USB 3.0 works flawlessly (which can't be assumed; ask me how I know) and the eSATA connection allows booting from the connected drive. Grant Bennet-Alder's point about HD speed is important to consider; in addition, the size of the individual files being backed up and where on the backup disk they're going will affect overall transfer speed. For example, using the USB 3.0 connection on that CalDigit card going to a Toshiba 3TB external, the transfer rate for a big file (say a virtual machine file) from an internal SSD boot drive was about 145 MB/sec while a bunch of little files might drop to 30 MB/sec and both rates decrease as an inner partition on the external is used. All told, a nearly 700 GB backup took under 1.5 hours. Using a HD as the source added almost an extra hour, though a WD external was used for that. Using a WD green drive plugged into this http://eshop.macsales.com/item/NewerTech/FWU3ES2HDK/ with an eSATA connection took about 2.5 hours also, but that was bootable whereas the USB 3.0 connection is not.
Another point to consider is that USB 3.0 is ubiquitous on PC's now so there's lots of price competition for externals; not so much for eSATA externals.
