BNC-2110 entry limit is 5V?
Hello, I'm trying to measure the magnetic field by using hall sensor,
I created wave sin simulated with amplitude 10V
However, it seems that BNC-2110 is only measure up to +-5V?
Is it OK to switch to 10V so I can display + 10V range?
Thank you very much for your help!

I use BNC-2110 as interface to connect to the PCI-6280, I checked this interface card. I wonder if this curd can be used for current analog measing (I mean directly). It accepts input of current analog?
and one thing, when I open the module Measurement & Automation on my PC, I am not available to pinout of the BNC-2110, I see some channels and a weird pinout. I have to map this pinout to BNC-2110 card? If so, anyone know how I can do?
MiladAk has writtenoes it accept input of current analog?
# You can use resistance feel draft however. I = V/R. If you measure V and you know R, then you can easily calculate I.
Im a using a card of data acquisition of 6221 with a block of connection BNC-2110 connected to it. For the e/s digital terminal block provides an additional 5V input. Unfortunately I don't seem to find any information as to know if this provides additional current to the TTL signal or no training. Is there an internal pilot in the terminal block, or - if I need to connect external relays to the digital output - always connect a current driver in between?
Yes, you will need external circuits if the external relays require more current than can provide the DAQ card.
BNC-2110, 6023E PCI card and Labview V9.0: sensitivity of data acquisition (change more little detectable voltage) is 0.002V
Hi, I use the software/hardware above to read a voltage of a potentiostat world Precision Instruments No..
I'm trying to record changes in voltage as low as 0.0003V but using the wizard DAQ, I seem to be limited to a sensitivity of 0.002V. This is the limit of real sensitivity or have I missed something?
Any help would be greatly appreciated.
Thanks for joining the forums!
The PCI or 6023E has a 12-bit ADC. In other words, it can make the difference between 4096 (2 ^ 12) different levels within the range of cards. The card you have has a selectable range by ± 10 V, ± 5 V, ± 500 mV or ±50 mV software.
This means that the minimum detectable variation will be 4 mV, 20 mV, 244 µV or 24, depending on the chosen range µV.
You should be able to use the ± 500 mV or ±50 mV to get the least significant bit (LSB) value, you need, even if it means that your signal is located between these values. If not, then you need to consider other materials to the application, or the addition of external circuits across the signal.
I'm controlling current source of third parties using the connectors of analog output on my card PCI 6251 and BNC-2110.
The current source needs an input signal of 0.1V. I tested it using a battery, the potentiometer and the voltmeter, and by manually adjusting the voltage of power current works - current output with control voltage scales according to the specifications and is relatively stable.
The data acquisition card works too - when I connect a voltmeter to the AO0 AO1, the measured voltage corresponds to the target with great precision value.
But when I connect the current source of third AO0 AO1 data acquisition card, the measured output voltage drops and fluctuates. This applies to both channels of the AO.
I wonder what is the problem here. I suspect it could be a matter of the grounding - the current analog control of the source is an entry with two floating terminals differential. I tried to return the switches FS/GS on the BNC-2110, but that makes no difference.
Anyone knows similar behavior? Does anyone have any suggestions?
I want to read analog input using BNC 2110 as an interface connected to the PCI-6280. In the first step I want to use the Signal Express to see only the data, but when I choose one of the input and then string I want to see the connection, I get this message:
Connection scheme tool does not send the accessory on the connector 0 of your device:
Please select one of the following accessories to display the supported connection diagram:

What should I do in this step?
There is this sentence in the Manual "the BNC-2110 is only intended for differential analog input signals. The 16 channels HAVE on PCI-6280 are mapped to 8 connectors BNC AI0 - AI7 on BNC-2110. HAVE [n] with I [n + 8] represent a differential channel. This means that if you select channel differential AI0 in Signal Express with Terminal configuration it will also use AI8. These two channels is represented by a single BNC connector (connection central driver is positive = AI0, negative connection is shielding = AI8).
I have a vi that is 4 kHz of sampling data... At this rate, I would use the counter on my BNC-2110 for hardware DAQ BOF schedule rather than the clock on board... However, do not know how to obtain and use the data from the meter... I guess I need a thread linking some of the pins on the device (for example PF01, CRT0, etc., what are all these input/output pins for?) and the meter would be used in a certain type of setting to relax in vi code? I am beeing trying to figure this out for a while, but can't find anything which provids a nice simple description...
Any help would be greatly appreciated.
The sample clock is the clock that uses the A/D. The source is usually the internal clock on the DAQ hardware. You do not have access to the pc clock. Let the clock source inside and forget options for now.
I try to use the PXI-6250 by BNC-2110 relay 5V. Please advise if this is possible and how.
It is certainly possible, but there are some limitations. Are there current requirements for the 5V relay. If it is low current, you should have no problem controlling the relay with one of your PFI lines (they are located in the Terminal screw of the BNC-2110).
I use the VI 'Invite to user input' to enter a text in the field for the "text input box. However, I need to limit the number of letters of this entry. Someone has done this before?
P.S. You, of course, will need to create your own version of this Express VI. Just convert the Express VI into a regular VI (right-click on it and select "Open the front panel".) This will give you a copy of the VI that you can modify.
Hi, I have an acquisition of data PCI-6115 and BCN-2110 connector card I want to measure continuous analog voltage. Now I can permanently measure the intensity of light laser of photodiodes through channel 1 and get the reference through the 0. Then I can get the harmonic signals by the multichannel lock - DAQmx.vi. However, I also want to simultaneously detect another analog signal in channel of gold voltage 2. The problem is: Channel 2 voltage range is approximately 0.3 mV to 6 mV which is significantly lower than the other channel 2 (0 - 10V), how could put different prescription by channel continuously and simultaneously acquire all data?
I found that Dennis Knutson has provided the solution a year ago, which is listed below:
In the solution, it should be arrays of strings, lines, patterns, but I do not know how to apply it to my case. Is there a suggestion or another solution?
Thank you very much!
You have the autoindexed exit task and is not correct. Try the code below.
I have a problem with the map 6062E. This is my version of LabVIEW 2010. As is apparent from the attachment, MAX is able to find the device and his name is "Dev17". Also on LabVIEW control channel side found this device and channel a0. What is perhaps my current installation wrong because I get this error all the time?
I did some tests on the side of MAX and channels measure the voltage in a correct way.
Thanks in advance,

This is first time I am doing data acquisition and the BNC-2110 present can be connected to PCI-6010. How to make a Board for it?
I'm not sure what you mean by "some"; The BNC-2120 exposes all channels HAVE and AO on connector 0 of a standard feature of E, M or X series.
- Eight BNC connectors are for eight differential channels of I. For example, for the BNC connector labeled 'I 0', the Center connects to the 'I 0' pine and the outside connects to pin 'HAVE 8'. (The BNC-2120 probably would not be a good choice for someone who wanted to use the channels in unbalanced mode).
- Other two is for the analog output; the centres are ' AO 0' and 'AO 1' and transmissions are related to "AO GND".
- There is another connector BNC for PFI 0; all other PFI (with the exception of the 10, 11 and 15) are broken down as screw terminals.
- Other BNC connectors connect what either directly (the unit is powered by the + 5V line but otherwise works autonomously, and the "user defined signals' are connected to terminals to adjacent screws).
It seems like it wouldn't be difficult to have a cable that was going on a PCI-6010 the 37 pins on the connector 68 pins on the BNC-2120. I'm a little curious as to why we do not have one. Possible reasons off the top of my head which may explain why not:
- cards PFI/description would be a mistake (for example, on a series of E/M/X ' CTR 0 SRC "PFI 8; on the 6010 is PFI 0.)
- No digital lines (E/M/x series P0.0 P0.7 via are independent; on the P0.0 6010 P0.5 and P1.0 by P1.3 are shared with PFI lines)
- Confusion about being able to connect to other devices that we sell with connector d - SUB 37 pin, but who do not use a compatible pinout (for example, the PCI-6239, PCI-6510 or the NI 9237). Here again, a PCI-6703 also uses a 68 connector pins, but has a completely incompatible pinout as well.
But it seems that those who would be pretty easy to deal with, because it is useful to be able to connect to the BNC-2010. Maybe it's an idea for the Exchange of ideas information Acquisition?
Anyway, if you want to have pushed BNC for everything on your Board of homebrew will need you:
- 8 or 16 BNC connectors to HAVE, depending on whether you want single-ended or differential. For differential, the centres are GOT by AI 7 0, and transmissions are AI by AI 15 8. For asymmetric, the centres are HAVE 0 through 15 AI and transmissions should all connect to GND AI.
- HAVE a sense (I think that you only need this if you use channels Nonreferenced Single - Ended (NRSE). See also: noise considerations for analog signals and field wiring.)
- Two for AO (centers are AO 0 and 1 AO, outers times connect to AO GND).
- Ten for PFI/digital lines. Outers will connect to GND D.
Up to a maximum of 29. You want maybe less, depending on your application.
Limits of data located in the property entry seem to have no effect on data entry. A value written to a property node limit the contribution of the increment of buttons but not the data which are entered in the control. How to stop digital control to accept out of desired range values? In the attached example, why I can type in any number for control and data entry limit is ignored?
In the Properties window of data entry for the digital control, you have the "answer of value out of range" ignore the value. Change it to compel.
I use NI BNC-2110 adapter and NI USB-6251. I wonder if the BNC multiplex channels at the same time or separately and what is the stage of late (speed switch) so he can switch from one channel to another when I acquire data from several channels. Is the speed of switch function of the rat sampling or fixed if the channels does not collect data at the same time? There are shifts of time between signals from different channels in my test.
And I'm confused about how to set different sampling frequencies for different channels and creat local virtual channels pointing to physical channels. It is said in the following link if the channels have a common divisor, I could implement your task.
Thank you very much.
The USB-6251 case will use a multiplexer to sample multiple channels, which means that there will be a delay without a sample. The actual amount of delay will change depending on your configuration, but I included some items of knowledge base describing the delay and also have the formula to calculate your delay. The rate at which the multiplexer is switching comes from the clock to convert.
The article you mentioned describes a way to configure your acquisition to taste a channel more often than another channel based on the same clock. As shown in the example, you can enjoy the 1 three times and channel 2 times for a single edge of your sample clock. The question is that if you're levy channel 1 three times, samples are taken with a delay based on the clock to convert, not a sample clock. The picture in the article shows how samples are scattered, is not the same at a clock frequency sampling more quick example based on the time between samples.
What the clock Convert (channel) rates determined in NOR-traditional DAQ OR DAQmx?
Difference between the sample clock (clock scan) and convert (channel clock)
Hi everyone, I am working in a project where I'm forced to use both a PCI-6723 connected to a BNC-2090 case has... In the datasheet of the 6723 only to versions of the BNC-2110 and 2115 are suggested. Anyone know if I can still use the one I have no problem? I mean, it is, is always compatible 2090, do I have to make some adjustments to the hardware/software, or this is just a desperate mission?
Boards are good, thanks for the help.
Has BNC-2090 is specifically designed for the X-Series, E-series, M-series and S-series.
The PCI-6723 belongs to the series of analog output and for this reason BNC-2090 has not supported this Commission.
The best connection BNC block for this is the 2110. This connection block lists the series of analog output as a series of supported.
