• CAN transmit/receive same Port using USB-8473?

  Hi, I'm new to the CAN interface. I have a USB-8473 attached to my USB using Labview 11. I write labview routines to use the port, but since I don't have 2 of them, I thought just to transmit a data frame and read it on the same port for testing purposes. Currently I'm using transmission same reception Port.vi example, just to see, if it works, but when I run the VI and transmit data and then set the RTR bit to receive the rear frame, nothing is ever reported. Are there any additional settings I should do before using the device CAN 8473. I even tried setting the attribute of free reception as well and nothing ever gets the spokesperson. I use a baud rate of 125K on CAN0 flow. Can someone help me understand why it does not work?

  Thank you.

  No.... everything will be virtual (pass on 256, 257 reception). NI-CAN comes with two virtual ports internally interconnected. They are not exactly the same as a real port, but it can help you to carry out tests.

• Change in the ID of arbitration with the help of usb-8473

  Hello everyone,

  IAM using USB 8473 Receive messages on CAN Bus. For what Iam using CAN Receive.vi and Net Interface Logging.vi. IAM receiving messages correctly, but I have a problem in arbitration received IDS. If the current arbitration ID is 0 x 14FF0001 (Extended) then Iam receive as 0 x 34FF0001, and if the arbitration ID is 0 x CFF0127 then Iam receive as 0 x 2CFF0127. However, the channel in the frame information is correct. Can someone help me how to fix this problem. The first 2digits are 14 is dispalying 34 or if the first digit is C, it takes 2 c.

  Thank you

  Thanks for the reply Matt. I could find the solution.

• How to use USB CAN 8473, code for the basic example

  Hi all.

  I use NEITHER USB-8473 CAN transmit and receive data via CAN.

  I have traveled a lot a lot of pages related to this and realized that the API will not work for USB - CAN. Can someone tell me please how to use this USB-8473.

  Maybe an exaple program would help me. (It is not PCI it we USB,)

  Thank you.

  You will need to install NI-CAN, if you don't have already done.  This is the API that you can use with a 8473.  After installing, open Explorer Measurement & Automation and make sure that you can see the 8473 under your devices.

  Here is a sample VI (LabVIEW 2009) that I wrote for another developer to make the CAN communication basic tests.  You enter a package CAN as a series of hexadecimal bytes separated by spaces, and it will send it to you.  It displays every CAN packet it receives in the same format.

• The CAN bus activity: why can I not see my CAN bus activity using MAX and a NI USB-8473?

  I use an NI USB-8473 and Measurement & Automation Explorer on a CAN bus I know works.   He does not see as a traffic CAN bus.

  Any ideas on how to trouble shoot to find out why this material does detect any signals at all?

  DOH!

  We've all been there.  I'm glad you have work.

• USB-8473 BusMonitor error frame

  I use a USB-8473 to monitor messages sent by a 'new' module J1939.

  The BusMonitor that comes with the USB-8473 tells me that there are frameworks of the error on the bus.

  Most of the time I see 00 00 01 AA for the first 4 data bytes (although there are other messages of 4 bytes seen).

  Is there a list somewhere that tells me what it means?

  Thank you.

  

  
  

• CAN read Interface of USB-8473 programmatically

  Hello

  I'm looking for an example to get the name of my usb-8473 card BOX interface. I developed an application for his colleagues and I do not know CAN name of the interface they use (CAN0, CAN1,...). It will be great if I could read this name in my application, to set properly the name of the object of the communication CAN I setup and opening.

  As joined, an example that I started but I can't finish.

  

  Location of data in MAX:

  

  I work with:

  LabVIEW 2012 SP1 (12.0.1f3), 32-bit

  MAX 5.4.0f0

  NI-CAN 2.7.4

  Thank you

  If it were a XNET device it would be detectable in a similar method, but I * think * the only way I found to do this in the past is to provide an array of names of interfaces and use ncOpen.vi. Something like the following:

  

  Edit - you can easily try something similar to create a table of connected interfaces (if you have several devices)

  Hello

  Have you seen yellow errors such as exclamation points in Device Manager?
  If not, in this case it of not necessary to install all the drivers.
  Moreover, the operating system automatically recognizes the USB ports.

  But what USB device doesn't work? As far as I know if this external device needs more energy than the 500mA so it is possible that the operating system can not recognize this device.
  In this case you need an external power supply for this part or you try to use the USB hub.

  Good bye

• After the BIOS update can not startup Satellite C640 using USB key

  After upgrading my bios Toshiba Satellite C640-10F (PSC02E) to WIN 2.00, I can't boot the laptop using USB key, when I checked the BIOS with F2, I was stunned because the USB port connected to the laptop has been labeled as FLOPPY drive. Y at - there no possibility to downgrade the BIOS?

  Thank you

  Stand by.
  Set the BIOS to default and after restarting, use F12 to get into the boot menu.
  USB option is available there?

  Hello

  Yes, you can put any SDS/disc HARD SATA to USB HDD enclosure and you can use it as any HARD drive externally.

  Kind regards.

• Is is possible to access channels from a database in labview with NI USB 8473 s

  Hello

  I would like to know if it is possible to access a database BOX, which is downloaded through MAX, in labview.

  Specifically, I downloaded my CAN of database to the MAX and I want access to each specific channel in labview.

  IE according to the photo, I would like to have access to the canal of n_Motor_InsRpm of E1_L0_1 (motor speed) in Labview, in order to define and pass a value of speed via CAN. Would this be possible with the NI USB-8473 s? If so, is there a simple example in Labview?

  Thanks for your help

  Charis

  There are several ways to get information from database without the need of hardware. Here's one I made earlier.

• It is possible to contact PCA9548A (8-CHANNEL I2C SWITCH) using USB-8451?

  Hello

  Now, I'm doing a project related to the smart battery. Now, I read data from a stack using the USB-8451 by smbus. The next step uses the USB-8451 casing to read the data of several batteries through smbus. I chose the PCA9548A (8-CHANNEL I2C SWITCH) to achieve this goal. But when I check the specification of the PCA9548A, there is a fix I2c format to read data from it, I tried several times, but still no can tell me where is the error in my code, or maybe it's impossible to communicate with this chip using USB-8451?

  Here is the fix that i2c read format of PCA9548A

  Why are you usng the script live? Have you looked at the examples of delivery for the 8451? You just need a couple of nodes property to set the rate and the address, and then use the VI to write I2C.

• Digital output (0/5volts) using USB or RS232?

  Dear friends, I need to turn on and turn off a device using a few transistors... ect. I would like to turn on/off using USB or RS232 of Labview... I just need to provice was looking for 0 or 5 volts to... Please help me.

  Here's a little test vi

  

  Now take a DMM and check the voltage levels on the line DTR and RTS of the COM port you

  

  Should be 9 male pole D sub, careful of not to shortcut some ankles!

  measure between pin 5 (GND) and PIN 4 (DTR) or 5 & 7 (RTS)

  To light a LED, I would start with a LED of current low and a 10K resistor.   If you have the LED's operating replace by an optocoupler and resistance in order to limit your current below 5mA. (Say (12V_level - 1.8V_led) / 5mA-> ~ 2.2 kohms)

• How properly using USB 6251 to measure the DC voltage

  Hi all

  I have a problem as in the http://forums.ni.com/ni/board/message?board.id=170&message.id=404676&query.id=250408section.

  I'm sorry for the repetition of the subject, but I read all your advice and have not yet solved the problem.

  My task very simply: I use USB-6251, differential mode to measure battery voltage Energizer 1.5V. But result shows > 10V? Mean.VI shows greater 4V (see attached photo)

  I do not understand what happed with my task?

  Please help me!

  Thank you very much!

  Hello

  Please post on the Forums OR!

  How do you have your battery connected? Do you use polarization resistors? This could be a grounding problem and can be fixed if the polarization resistors are used. See table 1 in this document , and the differential configuration for a floating source.
