Scxi-1349 versions

Hallo all, I have a doubt.
In the past, I'm sure I have seen a document (on NI website or Devzone, but I can't find it now easily), where I read that it is necessary to choose different versions of the SCXI-1349 module, when you use this adapter, connected by a 68 pin cable, with E-Series DAQ or M-Series DAQ. Is it true?
If that is the case, which is the association between the different types of DAQ Board and different versions of the Adapter?
And how can I recognize the version of the adapters I have bought in the past? Searching in some way with the S/N, or watching, for example, a label on the product?
Thank you for your help!

Hi Stefano.
SCXI-1349 is fully compatible both with E-series DAQ and with M-series DAQ.
If you use E-Series DAQ you must connect the card to the connector with SH-68-68-EP cable, indeed you must use SHC-68-68-EPM cable with M-Series DAQ.
For many infos you can chek the following links:

What is the difference between SCXI-1349 adapter and DIO-24 adapter(in SCXI-1353 assembly)

I have an SCXI 1353 cable assembly. How do I differentiate between these two adapters ?

Sasi,
Hello, the SCXI-1349 adapter is is used for connecting 68-pin MIO E Series devices to an SCXI chassis.
The SCXI 1353 (comes with two adapters) is used for connecting 100-pin MIO E Series boards to an SCXI chassis. The first adapter is identical to the SCXI-1349, while the second adapter routes the extended analog or digital signals to the SCXI digital modules or breadboarding modules.
Good luck with your application!

Connect signal to scxi-1349 male breakout connector directly

Dear all,
My hardware are pci-6259, scxi-1000, 3 scxi-1102b. I connect scxi-1000 to the connector 0 of pci-6259 for ai signal acquisition. It's works well. But now I want to get counter signal(encorder) too.
My question is whether I can connect counter signal to scxi-1349 male breakout connector directly use a connector made by myself or not.
I aleady try,but it does not work.
Thank you

Hi Alex,
I'm sorry you had to wait for an answer for quite a long time.
To be honest, I don't really get your question.
One AI Input for the Cable on the USB 6259 has the range for 16 Signals.
So you can't send 24 Signals in one cable, as long as you don't add the signals in diferrent frequencies
and seperate them afterwards programatically..
But if you just want to get the Signal in the normal way you would need 2 cables for that.
Regards

SCXI and Aquisition with Windows 7 x64

Our IT just updated our laptops and we received Windows 7 x64.
For data acquisition, we use SCXI hardware in the SCXI-1000DC chassis and a SCXI-1600 USB DAQ Card. In the process of getting my NI hardware configured on the new laptop, I discovered NI does not support Windows 7 x64 for the SCXI-1600. The other options to connect the SCXI-1000 to a laptop are the DAQcard-6062E and the DAQcard-6036E, neither which support Windows 7 x64. According to the information below, there are no plans to support x64.
What are my options to continuing using the hardware we have invested in with the laptop running Windows 7 x64?

For those USB devices, there are not currently plans to add support for 64-bit operating systems. This is due to incompatibilities between the USB design of these older devices and the USB implementation in 64-bit version of Windows.

You will need the NI SCXI-1349 connector block and the SH68-68-EP cable. The SCXI-1349 plugs in to the back of your SCXI module and the cable connects the 1349 to the USB M Series Mass Termination device. All of the rest of the setup is identical to any PCI/PXI E Series device. The USB M Series device will be the Analog-to-Digital converter for the system instead of the SCXI-1600.

SCXI 1112 and 1302 doesn't run at the same time

Hi,
I have SCXI 1112 thermocouple input module, SCXI 1180 feedthrough panel , and a SCXI 1302 terminal block connected SCXI 1000 chassis with SCXI 1349 adapter. I am trying to measure voltage by using SCXI 1180&1302, and temperature by 1112 module at the same time. When chassis is on SCXI 1112 runs without a problem; however, voltage reading coming through SCXI 1349 makes no sense (plus I can't run them at the same time, LAbview gives an error). While the chassis' power is off, it is the other way around, SCXI 1349 runs smoothly.
In addition to that, a radiometer, connected to a power supply, is wired to SCXI 1302 terminal block. When power supply is on, SCXI 1112 module's temperature reading is 4 times higher than actual value. In other words, power supply effects the readings.
Could you please give me some advice to solve this problem?
Thanks,
Azra

One piece of the puzzle you left out is the DAQ card being used in the host computer.
Without looking at some specifics on the SCXI cards/connectors you are using, I will comment you must be careful when you are using an 1180 feedthrough module. Keep in mind, the SCXI chassis is Signal Conditioning -- it's nothing without the DAQ.
I would recommend you back up a few steps, simplify the setup and test each input channel from MAX -- making sure you aren't overlapping channels between the 1180 to the DAQ and the SCXI chassis. Remember, most data from the SCXI chassis comes in on a single channel of the DAQ through the 1349.
Hope this might help.

Hi Sadok,
For your application it doesn't sound like you will need relays. It sounds like you might need a high voltage attenuator like the TBX-1316. This would provide plenty of protection coupled with your 1125's isolation. This may not work if your small signals are on the same lines as the potentially large ones are. Let me know what you think about the attenuator.

Shoud i use them together to connnect to SCXI system?

if i choose SCXI-1520,SCXI-1540,SCXI-1102 as the signal modules,can i choose PCI-6023 as the DAQ device? and should i use R6868 Ribbon cable and CB-68LP I/O connect block together for connecting the SCXI system and the DAQ device? or do i have other more considerable choice?

Yes the 6023E can control an SCXI System. To connect the DAQ board to the SCXI modules you will need a chassis such as the SCXI 1000. You will want an SCXI 1349 cable adapter and I would recommend a SH6868 shield cable if you are measuring low voltage signals so you will have less noise introduced in the cable. When connecting signals to the modules the best solution is to use the corresponding SCXI terminal blocks that mount directly to the SCXI modules.

What equipment is required to calibrate PXI cards.

I need to know what all is required, hardware and software wise, for me to calibrate the following NI items in my cal lab:
PXI-1045, PXI-6508, PXI-6552, PXI-8331, and PXI 6251.
What I have now is an old version 2.0 of Calibration Executive and the software that came with these cards (NI-488.2, GPIB-VXI/C Legacy Documentation and NI-VISA Libraries Version 3.0). My software guy also has the NI Developer Suite from 2003. In the lab we have calibrators (5700,5720,4708,9500) and meters (34401,3458,1281,8508) and scopes (TDS) and PC controllers running XP with NI PCI-GPIB cards.
I realize I will need to get an upgrade for the Cal Exec, I need to know what all else is required to decide if it is going to be justifiable to gear up for this capability. Any information, including prices, is appreciated.

Hi Poornima -
The SCXI chassis and equipment are used to condition signals sent to and from the DUT. After being conditioned, the signals are sent to your DAQ device to be digitized and read into the computer. As such, the SCXI chassis only needs to be cabled to the DAQ device. You can do this using a shielded E-series cable (SH68-68-EP) and an adapter block (SCXI-1349). These will connect the leftmost device in your SCXI chassis to your DAQ card, which must reside in the rightmost slot of your PXI chassis. There is detailed information about SCXI connections in the "SCXI Quick Start Guide", which can be found in the Start Menu documentation for DAQ.
The GPIB connections will be made in your PXI chassis. Either the embedded controller of the chassis or a PXI-GPIB card will have the port connections needed.
There are also detailed text instructions for making the connections in the "Calibration Executive Help" file, which you can find in the program's Start menu group. Inside this file, browse the tree to "Device Calibration Procedures » Modular Instruments » High-Speed Digital". The instructions given here explain step-by-step how to connect your equipment for both scenarios (combo chassis and separate SCXI chassis).

How do I use two DAQ cards in one Labview code? Current I'm getting error " error 200558 occurred at DAQmx Create Channel.vi. One task cann't contain multiple independent devices". Can someone help me?

The two DAQ cards are NI PCI-6070E & NI PCI-6052E. The Labview I'm using is labview 7 Express and the Window system is Window XP. I'm using NI SCXI-1000 chasis and SCXI-1102 & 1102B two modules plus a feedthrough SCXI-1180. 1102 is connected through SCXI-1349 cable to DAQ card 6052E while 1102B is connected through SCXI-1349 cable to DAQ card 6070E. SCXI-1180 is connected to 6070E through SCXI-1349 adaptor on the back of 1102B.

Sarah, thank you for replying my question. It seems that I'm making progress everyday (smile). I'm able to run the test using both daq cards in my code now. But as I'm moving forward, I'm getting new questions too. How do I use one STOP button to control both tasks and how can I save data into one single file?
I attached my code here hoping you can get the specifics on my application by looking at the code. Thanks very much!

Can I use parallel and multiplexed mode?

Hi,
I have
a NI USB-6259 DAQ Module (Two Connectors with to Cables to two SCXI-1349, which connects the DAQ to the Chassis)
a SCXI-1001 Chassis
3 SCXI-1143 8 Channel Low Pass Filter Modules
and
a SCXI-1180 Front End Plate
As the DAQ has 16 diff. AI Channels, I would like to drive two SCXI 1143 in multiplexed mode(connected to Connector 0 at USB-DAQ via SCXI 1349) and one in parallel mode assigned to AI 8-15 (Connected to Connector 1 at USB-DAQ via SCXI 1349) .
The configuration is approved by MAX
But when I run it with the software I get an error saying that a simultaneous scan is possible Error -223835. And that the selected channel is not in the task Error: -200486.
Can one DAQ device(like NI USB-6259) be assigned with Channels 0-7 in multiplexed mode (multiplexing two SCXI 1143 8 Channel) and the rest of the channels in parallel mode for on SCXI card? NI-USB 6259 has to separate connectors but is it still seen as one DAQ card?
What does the error say? I thought I configured for a simultaneous scan.
Attached to this post is a picture:
Top Left: Back view of my NI USB-6259
Top Right: Front view of my chassis with three SCXI 1143
Bottom: Back view of my chassis. Two SCXI 1249 are connected to two Cards. One card should be run in parallel mode, two in multiplexed mode.

@ Lorenz-Mie
you are right that I need a new DAQ device, but as stated in the M-Series manual on page A-108:
"Use Connector 0 of your M Series device to control SCXI. NI-DAQ 7.4
and later supports SCXI in parallel mode on Connector 1."
Thats what I've done. I'll keep on trying.

Error-200284 for PXI-1010 MXI-3 fiberoptic connection to a PXI-6533.

In the instruction lab in which I work, we have two types of systems:
1)SCXI-1000 chassis connected by copper to a PXI-6035E card in a PC.
2)PXI-1010 chassis connected by fiberoptic from a MXI-3 to a PXI-6030E card in a PC. A PXI-6533 handles the digital I/O.
We have LabVIEW8.5.1 running on both types of systems. On the SCXI-1000 system, the LabView example Acq&GraphVoltage-IntClk-DigStart.vi runs just fine. It does not run on the PXI-1010 systems. Instead, I eventually get Error-200284. In both cases we use PFI0 or PFI1, and digital ground, for the triggers, connected to lines 38, 39, and 33, respectively, in the SCXI-1302 terminal block, which connects to an SCXI-1180 feedthrough panel.
I searched the forums and all ni.com for information on this problem, and have not been able to find any relevant information.
Joseph D. Rudmin

Hi Joseph,
I think I'm starting to understand the problem you are having. Unfortunately, since on a SCXI module, all channels are generally multiplexed through AI0, the PXI/SCXI backplane only shares the necessary channels i.e. one AI channel and any required timing signals. Therefore, even if though you are using the SCXI-1180 module with a SCXI-1349 communicating adapter, you will not be able to access the other channels on your PXI-6030E since there is no physical connections being made to those channels in the backplane. There are 2 solutions around this problem:
1. You can use an SCXI-1349 cable assembly to connect the front of the PXI-6030E module to the back of the SCXI-1349 adapter. This way the unused pins on the DAQ module can be accessed through the SCXI-1180.
2. You can decide not to use the SCXI-1180 and simply use a standard 68-pin terminal block with your PXI-6030E and connect your 5V sync pulse to the PFI pins. This will still allow you to sample off of the SCXI-1100 since those channels are connected via the backplane.
Here's a link to our online KnowledgeBase article which talks about this issue.

Power control switch for 115VAC wall outlet to operate resistance heating element.

I am very new to LabView software as well as hardware
interfacing, so don't presume that I know anything. My problem seems
simple, I want to be able to control and automate via LabView software a resistance
heating element that can plug into a standard 115VAC wall outlet. I
searched through the Knowledge Base and found this comment:
http://digital.ni.com/public.nsf/allkb/855AF9CBDAACE3018625725A00638653
The PXI 2564 seemed ideal but I have no clue how to connect the serial port to
my heating element, or even if this is enough current (5A, do heating elements
need a certain wattage?) I had originally envisioned a simple surge
protector like device that had computer control options. Many devices
like this are available, however all the ones I have found are web-accessed via IP address
and I am unsure how to interface this type of device with LabView if it has its
own GUI. Obviously I have no idea what I am doing here so any help would
be much appreciated. The heating element requires 115VAC or DC it does
not matter, and all I need to do is turn the power on and off, no variance is
required, although that could be very useful. I have implemented a NI
CompactDAQ for other control and measurement (24VDC Digital I/O and Thermocouple) if this
could somehow play into my solution, but I believe the limits on voltage for
this device are much lower. Thanks!

Hi Anfu,
LabVIEW gives you the power to control and automate all National Instruments hardware using NI drivers (i.e. NI-DAQmx).  I have a couple of NI hardware suggestions, but it's up to you to decide on the hardware that will best fit your application. Even if you end up using third-party hardware, I think you will find LabVIEW is a great interface to control and/or automate your hardware.
The resistance heating element you want to control...you state it is powered via wall voltage, but you did not state the required current. This is important information you should be able to find in the heating element's data sheet. The amount of current you need at 115 VAC (or DC) will determine your desired relay characteristics. Once you know the voltage and current (or power) the heating element requires, you can calculate the hardware specifications that are necessary for your application - and can confidently select the correct hardware.
Starting from the fact you need to switch wall voltage, you will want a switch rated for Measurement Category II (CAT II). This classification ensures you will be kept safe from the high voltages being switched.  National Instruments has PXI hardware that can switch wall voltages, as you mentioned previously, and one of these switches is the PXI-2564.  Your computer would communicate with the PXI-2564 through its PCI bus, not its serial port. Several methods to connect your PCI bus to PXI is to purchase a MXI-4 card (this would fit in one of your computer's PCI slots) that cables to a PXI chassis (in which the PXI-2564 is located). Also, you can purchase an embedded PXI controller (then you wouldn't need a separate computer, as the embedded PXI controller houses a laptop-like computer). In total, you would need a PXI-2564, a PXI chassis, and either a MXI-4 or embedded PXI controller.
If PXI doesn't seem ideal, instead you could create a Plug-and-Play (PnP) SCXI system!  First, choose a SCXI switch module (such as a SCXI-1127). Then, you can purchase a USB-1357 to control the SCXI-1127 module from one of your computer's USB slots. In total, you would need a SCXI-1127 module, a 4-slot SCXI chassis, and a USB-1357.
Another option is the SCXI-1161. Unfortunately, the USB-1357 doesn't connect to the rear of the SCXI-1161, but there is there are two additional options available for controlling the SCXI-1161. One is to purchase a PCI DAQ module (or use one if you already have one) and connect it to the SCXI-1161 using the SCXI-1349. The other is to purchase a SCXI-1600 (which is a DAQ board, SCXI form factor) that you control via USB. In total, you would need a SCXI-1161, a 4-slot SCXI chassis, and a SCXI-1600 or a DAQ board and a SCXI-1349.
Either way, the PXI and SCXI options both give you the full functionality of a modular, LabVIEW-controlled switch. Upon purchasing the switch module, you also get the required drivers, getting-started and troubleshooting tools (such as the NI-SWITCH Soft Front Panel), and examples to get you up and running quickly.
In reference to the simple surge protector like device that has computer control options - I'm sure someone from the LabVIEW forum could assist you in communicating to one of these devices via the web. Don't worry, if the device can be controlled via the web, you're good to go.
Lastly, in response to your final statements, it is important to find out how much current or power the heating element requires because that will directly determine your required switch hardware specifications. You mention no variance is required, which is good, because the switch will simply turn on or off the power to the heating element. I agree a NI CompactDAQ option could be very useful for an application such as this, however there are no CAT II relay or switch modules for this form factor at this time.
Hope this helps!

PFI 10

Hi,
I am trying to use cntr0 in my USB 6251 Mass Term, but it seems that only Ch. A is getting pulses. I have checked the entire wiring from my quadrature encoder all the way through SCXI 139 connector and to the 6251 terminal. Everything is OK. When I connect my encoder to cntr1 it works fine, but I need two counters for two different tasks. I also tried to monitor PFI lines individually as digital inputs. I could check PFI 8 (Ch. A, cntr0), PFI 3 (Ch. A, cntr1) and PFI 11 (Ch. B, cntr1) successfully, but when I tried PFI 10 (Ch. B, cntr0) the Measurement and Automation Explorer gave me error that PFI 10 is reserved for another task! I don't run any other task.
Do I need to do some initializations or configurations to have access to cntr0 or PFI 10?

Hi Javad,
PFI 10 and several other lines are reserved by SCXI: Using the Digital I/O Lines on an E or M Series DAQ Board While Controlling an SCXI Chassis
Through the DAQmx API, you can specify a different B terminal for your encoder task, such as PFI12: use a DAQmx Channel property node to set the CI.Encoder.BInputTerm property. Unfortunately, I don't think the DAQ Assistant supports this.

Configuration check request

we need test 10 pieces of thermocouples ,3 LVDT signals and 3 strain guage at one time.we both want the configuration of the signal conditioning and DAQ device meet our requirements and the low cost,so we select the following configuration:
SCXI-1000
SCXI-1520
SCXI-1330(instead of SCXI-1314)
SCXI-1540
SCXI-1330(instead of SCXI-1315)
SCXI-1102
SCXI-1330(instead of SCXI-1300)
PCI-6023E(12 bit is enough)
SSH6868
SCXI-1360,SCXI-1361
we hope these selections can make a whole DAQ system,could you check the configuration and please tell us if there is existing any mistake,and welcom better configuration. thanks

Instead of the SSH6868, you will need a shielded cable assembly to connect your 60xxE (E-series card) to the SCXI chassis. You will require the SCXI-1349 cable assembly. It has two parts 1)SH6868 cable and 2) an adapter to connect to the SCXI backplane.
As for the choice of the DAQ card,you may find the low cost approach severly limits the system bandwidth and overall accuracy. The low cost E-series boards only have 512 samples of onboard memory, as opposed to 8192 for the regular E-series. This makes controlling buffered analog input more difficult. In addition, you need to understand that the rated sampling rate for the board is based upon a single data channel. As you have 16 channels, your "best" sampling rate would be approximately 12.5 KHz per channel. The actual rate will be less. You have made no mention of the type of data you want to acquire (steady-state, dynamic, time domain, frequency domain), so, I can not give any better insight into the "best" sampling rate you could achieve.
Now, considering that you are mixing thermocouple (TC) readings with other inputs on the same DAQ call, you may find the 12-bit selection aggravates your data quality. When you acquire data using a multiplexer, the quoted accuracy for the device assumes that all of the voltage levels on the various channels are very near the same value. This allows a relatively uniform settling time for the input signal. It is quite possible that the TC inputs will be on the order of 2-10 mV while the other signals could range as high as 0.5 volts. Such a difference in input levels can lead to settling errors that are not obvious to the user, but can cause gross errors in the measured data levels. If you set the input range (only 4 for the low cost e-series) to +0.5/-0.5 volts, your resolution for the TCs will be about +/- 0.24 mV or about 6-10 degrees of error. (ouch!!). So you will be required to set different input ranges for the different input channels (0.05/-0.05 for the TC and +5/-5 or +.5/-.5 for the remaining channels. These multiple range calls can further limit your bandwidth by slowing down the "round-robin" interval between the data range changes. I know that your goal is low cost; however, you may find that the data quality is unacceptable. You will want to consider, at the very least, upgrading to the 6034E board. It is a 16-bit device (still only four input ranges); however, if you configure the board for only 1 input range, +0.5/-0.5 volts, your bandwith will improve and the TC resolution will improve by a factor of 16 times to approximately 0.015 mV (under 1 degree).
