Is the RTSI bus cable interface a direct 1 to 1 pin connection?

I am using a straight ribbon cable to connect the RTSI bus between two boards (AT-MIO-16E-1 and PCI-6602), but I am not able to receive the signal on the PCI board. (I am using RTSI0 as a gate for the counters on PCI-6602).

yes,
for my understanding the RTSI bus is only as bus with a 1-1 connection usefull, also i build this cable in the past by myself (and it worked).
Have You checked the description of both cards, there might be a difference in using of RTSI and what is needed as source for gate?
good luck

How can I output a digital value (0 or 1) directly with a VI on the RTSI-bus?

The Device is a PCI-MIO-16XE10.
Thanks.

The RTSI bus is designed for sharing timing and control signals between boards. By timing and control we mean clock signals, digital triggers, etc. RTSI is not meant to pass I/O signals, even digital I/O signals. Thus, it is not possible to connect one of the digital I/O lines on your board to a RTSI line. A way to accomplish what you would like to do might be to toggle GPCTR0's Output and connect that signal to the RTSI bus. You would do this by configuring the counter to perform event counting and counting down from a specified number of pulses on the source pin and configuring the counter's output to toggle on terminal count. You could also configure the counter to perform pulse train generation or single pulse generation. To connect the output to the RTSI bus, yo
u will need to call the Route Signal VI from the DAQ Calibration & Configuration Function Pallette with Signal Name set to RTSIn and Signal Source set to GPCTR0 Output.

Synchronization of PCI devieces via the RTSI bus using the measurement studio for Viusual Basic 6

Hi everyone,
I would like to synchronize a NI 4474 A/D card with a NI 6733 D/A card via the RTSI bus. Is there any way of sharing the timebase using the measurement studio for VB 6.0? It seems like it could be possible using the traditional NI-DAQ .DLL but I would prefer to do it with the ActiveX API.
I am quite desperate, since all my attempts to use the CWDAQTools1.RouteSignal and CWDAQTools1.RouteRTSI command failed miserably :-(
Thank you very much in advance!
Federico

Thank you very much indeed!
Unfortunately it doesn't really work... I cannot use the DI options since my A/D card (NI 4474) does not support DI/DO... When using the other option (CWDAQTools1.RouteRTSI) I keep getting an error message that this command is inapropriate for my device (even though it does have a RTSI bus and allegedly it also supports time sharing...)
Looking forward to your answer!
Kind regards
Federico

Register level programing of the 6601 counter to connect signals to the rtsi bus

I have need for more than 4 clocks and have several 6601 counter boards. I would like to use an additional board for the extra clock but need to send signals to the this board from the other. The most efficent way seems to be to use the rtsi bus to connect the 2 boards together. I am programing the counter boards at the register level using a kernel module in linux. The register level porgramming manual explains how to connect different signals to the sourse pins of the clocks including the rtsi signals. I have been successful in doing this but can not find info on how to route the output signal of one clock to the input of another using the rtsi bus. Using web search I have seen ways to do this using labview and dqmx calls but nothing for programin at the register level. Thanks for any help on this problem.

When does a clock signal appear on a RTSI bus using DAQmx for a PCI NI-4472 DSA?

Hello,
I am trying to synchronize several PCI NI-4472 DSA boards over a RTSI cable using MATLAB. I have read that with DAQmx it is not necessary to use DAQmxExportSignal to put the clock signal on a RTSI line provided that the RTSI cable is registered in MAX and that the DSA cards are listed as being connected to the RTSI device. Apparently, the DAQmx drivers are supposed to route the clock signal between the cards as required….
So I have done the above and see in MAX, in the device routes tab for Dev1, that
/Dev1/ai/SampleClock uses RTSI6
/Dev1/ai/SampleClockTimebase uses RTSI8
Right now I am monitoring the RTSI lines on an oscilloscope in the hopes of detecting a clock signal on one of the three boards in the system while one board (the eventual master) is acquiring data using the Test Panels in MAX. I am getting nothing on the ‘scope (may be monitoring the wrong line – have just posted a request for RTSI pinouts for this DSA) and am wondering under what circumstances is the clock present on the RTSI bus.
My real problem is that MATLAB R14SP3 does not yet support a master card in a synchronization application but, oddly enough, seems to allow one to setup slave cards. I would like to continue using the MATLAB data acquisition toolbox to manage the DSA cards and the application and would rather avoid using calls the DAQmx dll library. (It's not clear how to integrate the functionality of the data acquisition toolbox with direct calls to the DAQmx library.) So I am looking for a workaround to get the clock signal on the RTSI bus so that I may try out the slaves.
Thanks,
Sebulba

Hi
Both ports of a two port CAN board are handled by one processor and they use the same memory for alocating the necessary queues.
But, both ports if connected to different CAN buses have their own handle, own queues and error handling. That means if one Bus enters to BUS OFF, the second bus can still communicate. And you can stop and restart communication independently on both ports. Even the ncaction reset works on a single port at a time.

PXI-6682 read IEEE-1588 timestamp from 7953R over RTSI bus

Hi,
I am relatively new to LabVIEW
programming, although I have two years of hard experience using LabVIEW
FPGA tools.
So, I
have a PXI-1033 chassis, and I have plugged in an PXI-6682 IEEE-1588
card into slot 2 and a PXI-7953R card into slot 4. (Random selection
for slot 4) What I am trying to do is read the GPS timestamp from the
6682 card via the RTSI lines directly into the 7953R FPGA card.
Unfortunately, I have no idea where to start and what to read, and all
the examples (keywords: RTSI, IEEE-1588) that I find are for how to
read the IEEE-1588 timestamp inside the Host Operating system and
nothing tells me how to do it directly from the FPGA. My goal is to
build a machine that timestamps network packets that are being read by
the FPGA hosted inside the PXI-7953R card.
Can anybody point me in the right direction? I
basically want to learn more about RTSI, where the PXI-6682 outputs its
IEEE-1588 timestamp, and how data is transferred over the RTSI bus from
inside a PXI chassis.
Thanks,
John

Thanks for the response Alejandro,
I have a 7953R FlexRIO board with the Mimas Prevas Dual Gigabit Adapter Module (http://www.prevas.com/ethernet_simulator.html) plugged in. Ethernet packets enter the Mimas Dual Gigabit Adapter and then go directly to the FPGA as raw Ethernet frames.
From what you are telling me it seems like I cannot have a timestamp go from the PXI-6682 to the 7953R via the RTSI lines and to then be appended to the end of the ethernet frame before being retrasmitted out the other port of the Dual Gigabit Adapter. (With proper recalculation of the 32 bit CRC being done inside the FPGA of course)
I will do some more reading of the manuals and will then call NI Support.
Thanks again!

PCI-7833R RTSI Bus

I'm in the process of integrating a second PCI-7833R into my project (a towable wideband echo repeater for submarine target emulation).
The first board does the actual echo repeating (acquisition, trigger filtering, and detection, etc.)
The second board will do optional signal generation and transmit equalization.
Could I use the RTSI Bus as a data bus between the two boards? The project manager seems to treat them as general purpose IO.
Where do I find the pinout and function description for the RTSI Bus Connector as this info is not in the PCI-7833R documentation.
Thanks

Hi,
Yes, you can use the RTSI Line. However, you will need to connect the two 7833R board together through the RTSI connector using RTSI cable.
The user manual for 78XX describes how to access and use the RTSI line on Page 36 (RTSI Trigger Bus). This knowledge base entry also provides the RTSI connector pinout for National Instruments PCI boards.

Setting parameters for synching pci-6534 cards via RTSI bus

I have been performing high-speed,
buffered, looping output with one pci-6534 card. I am now adding
a second 6534 card that I need to sync to the first card via the RTSI
bus. I have successfully used the RTSI bus to see the master REQ1
and ACK1 signals on those channels of the slave (seen at a connector
block), using the "RTSI control" vi. I simply set the master and
slave as transmitter and receiver, respectively, over the RTSI bus.
The question is: Once I have used the RTSI control vi to share the
necessary signals, do I need to do anything in my "dio config," "dio
write," or "dio start" vi's in the looping output code for the 2nd 6534
card to let it know that its REQ, ACK, STPTRG, and CLK signals are
coming from the bus? For example, in the buffered pattern looping
output vi, the "dio start" vi has choices of "internal" or "RTSI
connection" for its clock. My master board's code simply uses the
internal. Does my slave need to be set to RTSI connection, or,
once I have shared the clock signal over the RTSI bus, is that
effectively the internal clock for my slave too?
I apologize it this question is confusing. Unfortunately, so is the issue.

Hello bwz,
When you are performing synchronization across the RTSI bus you need to specify that the slave device should get its clock signals from there. You would use the digital clock config VI to do this. If you look in the example finder, you will find synchronization example VIs that do the same kind of thing for analog input. To find the examples, open the example finder by going to Help >> Find Examples >> Hardware Input and Output >> Traditional DAQ >> Multiple Device.
If you are just getting started developing your application, you may want to consider using DAQmx. There are many more examples available to look at for this type of synchronization. To find these examples in the example finder go to Hardware Input and Output >> DAQmx >> Synchronization >> Multi-Device. To use your PCI-6534 with NI-DAQmx, you must have version 7.4 or later. The newest version is DAQmx 7.5. You may also want to look at this tutorial about synchronization with DAQmx.
I hope this helps!

Rtsi bus output on GPCTR0

I try to observe a trigger signal which comes from the RTSI bus with an GCPTR0 output (on a card PXI 6713).
I use the following function:
Select_Signal(idevice,ND_GPCTR0_OUTPUT,ND_RTSI_0,
ND_LOW_TO_HIGH).
Nothing happens. I don't understand.

Babat,
How are you monitoring the GPCTR0_OUTPUT pin? If you are using a scope, you need to be certain that you are sampling fast enough. Most of the trigger signals have pulse widths in the 25 to 50 ns range. To verify the present of the trigger signal on the RTSI line, you may want to route it to the SOURCE of the counter and perform event counting.
Good luck with your application.

I'm using Duet 2 Audio Interface with Garageband 09, when I connect my acoustic guitar to the combi jack I get a buzzing/humming sound. How can I eliminate this?

do you have any thing plugged into wall power? Audio interface, computer, speakers, amp for the guitar? if so are they all plugged into the same power strip? if so, have you tried another outlet?
Altertively have you tried a diffrent port on the combo jack? Have you tried a diffrent guitar cable? Have you tried a diffrent guitar or audio input device like a mic? Is the device directly plugged into the combo jack, or is it being routed throughs some thing?

Sample C code required to manage to GPIB controllers on the same bus

I am currently using a PC with LabWindowsCVI 8.5 and a GPIB-USB-HS interface to a rack of test equipment. I would like to modify my test software to hand control of the GPIB bus to a Fujikura splicer which can use the optical power meter already on the GPIB bus. When the splicer has finished splicing I would like the PC to get back control for the GPIB bus and carry on testing with the other instruments. The operator will click a continue button on the screen to identify when the splicer has finished. The splicer, power meter and all other equipment are all on the same GPIB bus as the PC.
Looking at the GPIB documentation I see that I should be able to grant CIC ( controller in charge) to the Fujikura and then get back CIC for the PC which I believe will be the System controller.
I have found the sendIFC() function which appears to get the control back to the PC can anyone tell me what the equivalent command should be to give control to the Fujikura? Also are there any standard checks I can do over the GPIB to check devices are ready to be controlled before carrying on testing?

Hi dcl9000,
The fujikura can be sent simple commands over a serial cable. Using this link we want to instruct it to make a splice with a given loss . To make this splice more accurate the fujikura can talk to an opm on the same gpib bus. When the splice is finished we need to use the opm and other equipment on the gpib bus from our test software running on a pc with the gpib-usb-hs interface. So the problem is how do we tell the equipment on gpib bus that for stage 1 the fujikura is in charge and for stage 2 the pc is in charge. If you have any ideas please let us know. Chris

Why has my native windows 7 Pro-64 network to a windows 7 Pro-64 VM has slowed to a crawl and freezes, after the new Arris cable modem was installed?

Please appreciate the details, so the complete situation can be visualized:
The office network:
New Mac Mini PC running Win 7Pro 64, (in boot camp), networked to an iMac running the same Win 7 Pro 64, VM, UNDER Fusion 7Pro.
To review: My treatment rooms former dell PC/running vista business/ running the server and network versions of my Dental practice mgmt & X-ray capture apps, had no probs WLAN to the front desk iMac running the same PC client dental network apps under the same vista business, & Fusion 4. The dell slowly fried its power supply .
I could not wait to replace it with a Mac mini/ boot camp/ win7 pro 64 bit, as it has to run natively to capture X-rays. The front desk iMac was also upgraded to os10.10.3/ Fusion 7pro/ and its own matching Win7 pro 64bit. The iMac is wired and WLAN connected to a netgear d600 router and a Time Warner Cable modem. The modem then failed and was replaced by an arris modem. As the Arris was configured out of the box, the network ran much slower slowed, as compared to the original modem. BUT- The Vonage 2 line phone system stopped working- no incoming or outgoing voices could be heard after it rang. Then twc remote configured it and the phone now works, but the network iMac slowed to a crawl, and now freezes when accessing the Mac Mini PC dental server to edit or enter data. The Mini perfectly accesses the internet via wifi. It accesses the front desk canon printer by wifi, and can print share they the iMac that is wired to the printer, as well, BUT, the network connection is a spinning pinwheel. The front desk imac easily finds the Mac Mini PC server on the network. It connects easily by entering the servers IPv4 address SHOULD THAT last value change. But if data isn't entered in slow motion, the window and app freezes, and has to be force quit by Task Manager!
Cause:
1. I think TWC switched the cable modem from the default- Non Bridged, to Bridged mode. Could this be the cause?
2. The network setting in fusion, on the iMac is auto detect, a setting that always worked with vista and with the new Win7 system, before TWC installed the new arris modem. 3. Switching to NAT does not work at all is there a different setting to use?
3. Does the Netgear Router have to have a port or pref configured so as not to block the Server.
4. might in need an Access Point (I have an extra netgear wdr3400) ).
5. Do I need an Extender that plugs into the AC LINE?
I hope this info helps.
PS:(some addtl info:
1. File sharing works fine between the minis -Mac and boot camp sides and between the iMacs- Mac and VM sides and between eother side to or from either of the 2 computers! 2. Also either office computer and all of my my home macs , (& my iPad, & iPhone), can access each other instantly and flawlessly, with splash top streamer and jump desktop remote apps, as controller or as client! In fact, the front desk iMac can remote control the mini PC AS IF YOU WERE DIRECTLY ENTERING INFO I TO IT!
SO I think it's either a misconfiguration in the TWC cable modem &/or some additional pref to config in the router? Thanks so much for your help, (been using VM's since VPC1. & Win95 in a iMac, 1999, DV MODEL! (TWC BLAMES VONAGE FOR NOT OPENING SOME PORTS IN THE TELE MODEM. Vonage blames TWC FOR NOTopeningj ITS PORTS IN THE CABLE MODEM, when they meant the ports on the Netgear. They have passed the buck for 6 weeks with not even a guess at what to do. VERY FRUSTRATING! Again, thanks to all!

Okay Saint Steven, I'll bite:
I read your description multiple times, very carefully, and I am still confused. May I suggest the following:
* Follow basic troubleshooting procedures. Isolate each individual problem. Don't try to get everything working at once. Make one change at a time.
* If I read your description correctly, the Netgear D600 (??) Router is the office LAN (not WLAN). Connect each piece on the LAN separately one-by-one, and test each piece individually. Get your LAN and its devices working first. Forget about the Vonage and the Arris Cable modem.
* Next, look at your Internet connection. Again, try each piece separately. Depending on how the original cable modem and the new Arris cable modem are configured, you may also have to adjust the configuration of the Netgear D600 Router.
* Finally, if you are still having problems, try to organize your thoughts and presentation before you post again. List each element in your network. List how each element is configured. Be systematic.
"Arris cable modem" does not help much - some are simple bridges, others are routers, etc.
To answer your questions:
1. I can't tell from your confusing description, but I don't think so. It seems like the problems are associated with the system changes you made (replacing Dell, etc.) and the problems seem to be isolated to the local LAN.
2. Auto detect should work, but it is easy to change and test, as long as you change one thing at a time.
3. No. The Netgear router should allow all communications on the local LAN. Could you have put the "server" in the DMZ?
Note: I could not find a Netgear "D600" model in a web search. Do you mean N600?
4. No. I doubt that you need an additional access point. Based on your description, everything appears to connect to the LAN.
5. No. See 4.
To repeat myself:
* Do careful, systematic troubleshooting.
* Provide carefully written, detailed description of your network and system configurations when you ask for help.
Good luck!

Software needed for the USB device, "USB Interface Controller TEST2.0"

My mother recently acquired a digital camera. She acquired it from a second-hand store, which did not include an interface cable or software. The manual (and the USB port on the camera) indicates that a male-male USB cable is necessary for photos to be copied to the hard drive.
I was not successful in locating such a cable at any local electronics store (I assume such a cable is now out-of-date). I purchased one from a seller on eBay. The brand is "e circuit electronics".
Upon powering up the camera with the cable connected to it and the computer, the following message appeared:
"Software needed for the USB device "USB Interface Controller TEST2.0" is not available. Would you like to look for the software on the Internet?"
I clicked "Yes". After an approximate two-minute wait, another message appeared stating:
"Software Update is not able to connect to the Internet. Please check your configuration and try again."
I deleted, "Software Update Preferences" in the Preferences folder inside the System Folder, without solving the problem. How do I solve the issue of allowing Software Update to connect to the Internet?

Thank you for your continued assistance, BDAqua. Unfortunately, the driver you linked to does not seem to be compatible with the camera. It is a driver for the V20 model, whereas my model would correspond to be a V2755, as referenced from a list of other Vivicam models when during a search at the Open Drivers web site.
From the system requirement about the card reader you gave me, it will not work, as this system is running 9.1. I am hesistant to upgrade this computer to 9.2, as I have experienced system unstability with that version, with even the 9.2.2 update applied.
In the mean time, I have e-mailed Vivitar regarding this issue, but have as of yet received a reply.
I am not certain as to other specifics to give you, in order to solve the Software Update problem. Please elaborate.
Yes eww, the computer in question is able to fully connect to the Internet for all that I need. I am fully aware of the difference between a computer connecting to the Internet, and a computer connecting to a digital camera. I have 15 years of Macintosh experience.

What is the PCI bus performance of the 1422?

I'm currently using an IMAQ PCI-1422 to acquire images from a camera. The image size is 1280x1024 @ 8-bits a pixel. Currently the camera can only run freely at 20 fps. So this data rate is roughly 26 MB/s. The IMAQ card seems to be able to acquire these images at that rate. However, I need to be able to retrieve these images into system memory at the same rate. At this time, I've only managed to retrieve the images at around 12 fps which is about 16 MB/s. Is this all I can reasonably expect from this card? There is no other activity along the PCI bus except for perhaps minor updates to the video display.
I'm acquiring images using a Grab. I use a callback on the Buffer Done signal to trigger an acquisit
ion running in another thread. Actually, I'd prefer to the acquisition in the callback itself, but I am uncertain as to how the callback is implemented and what I can and can't do in a callback. Is there documentation somewhere that I'm missing?
Oh yeah. I'm using MSVC++ and Windows 98.
Thanks

I tried the example and removed the clipping the ROI to the size of the canvas and also took out the image plot to make sure we would get accurate times. I get the same frame rate with that example as I did with my own code (around 12 fps). Also, I neglected to mention that for my own code I placed calls to timers just before and just after the call to imgGrab, and the time difference is what you would expect: about .083 seconds (average) to retrieve one frame.
I know nothing about the internal structure of the PCI-1422, but considering that we are retrieving images from the same SDRAM memory that is being used to acquire images, are we seeing some sort of bus contention on the PCI-1422 itself? Also, the camera I'm using is an evaluation board, and I have access
to the schematics and should soon have access to the CPLD design. So I can verify the design of the camera itself. I'm glad to hear that you expect to be able to transfer at 45MB/sec. That probably means that there is something not quite right either in the camera interface or perhaps in the computer system being used. But if you have any other ideas, I'd be glad to hear them.
Thanks for the response.
