How do I configure ports for PCI-1200 using LabWindows/CVI?

I want to use 2 ports of the PCI-1200 DIO ports as oup ports. Whenever I write to a port using WriteToDigitalPort, the other port will be reset.
Shoud I congigure the ports at the beginning of the program? If so How do I do it?
(LabWindows 5.5)

I would suggest using the lower level NI-DAQ functions instead of the Easy I/O functions. (You have a lot more flexablity this way.) To configure seperate ports use the function DIG_Prt_Config, then instead of using WriteToDigitalPort, use DIG_OutPort. Here is an example that writes to one port using these NI-DAQ functions. All you need to do to write to two ports is add two lines in; another DIG_Prt_Config and another DIG_Out_Port.
Good luck and let me know if this does not work for you.

Very simple question, how do you configure windows 8.1 to use a SF card as the default install location for software applications?

Very simple question, how do you configure windows 8.1 to use a SD card / external drive as the default install location for software applications? Primarily interested in apps installed from the windows store. This should be available in the settings
charm within the windows store. This must have been overlooked in the development of windows 8.1 or is a bug.

The registry method does not work with 8.1. I found this out the hard way. Doing it on 8.1 will leave you reinstalling the OS if you didn't do a SRP beforehand.

How to set "Configuration Variant" for a sales order item using function

Hello All,
I use function module 'SD_SALES_DOCU_MAINTAIN' to create Customer Indep. Requirements but how to set "Configuration Variant" for a sales order item.
Is their any idea or sample code?

Hi Zhijun zhang,
<u>http://help.sap.com/saphelp_nw2004s/helpdata/en/c0/98038ce58611d194cc00a0c94260a5/content.htm</u>
<u>http://help.sap.com/saphelp_nw04/helpdata/en/c0/980374e58611d194cc00a0c94260a5/content.htm</u>
A variant is simply an SAP report where the parameters for running the report have been set by the user and then saved with unique name. This allows future retrieval and execution of the report faster without reentering the parameters. As a convention the variant name should start with with the digits 50 so searchs for LHU variants is easier and quicker.
The first link will guide you by screen shot wise.
Award points if it adds information.

See Steve Newstrum's user tip "How do I use Port Mapping (Part I)". When it talks about giving your Mac a static IP address just substitute camera instead.

How to find COM port for a specific USB device

I want to automatically find the COM port for a specific USB device. I use the VISA find resource function but I can't get the manufacturer's ID. VISA says the device doesn't have this information. The find resource function does narrow my search (and often finds the port depending on what other usb devices are connected). In the case where it finds multiple possible ports, can I safely send a message to each port to determine if it is the correct device? I know it will work for my purposes but I don't know if I am asking for trouble by sending messages to unidentified devices. Any thoughts on how I can identify my device port will be appreciated. Thank you - Dave F

You can do it using WMI. I have C# code I am supposed to convert into LabVIEW foing something similar to what you want to do. In my case, I am testing a USB device and need to know which port on the hub is which COM port (the device creates a virtual COM port for communication). Using WMI, you can find the hardware path to the device and know that COM10 is USB hub Port 1 for example. Unfortunately, I cannot share the C# code.
You can download the WMI Code Creator tool from Microsoft, which should help you tremendously find the proper method of getting your info.
You basically want to look at all the W32_USB devices for the specific device you are looking for. Once you have that, you can look for the COM Port associated with it. I don't know when I will get to coding this up in LabVIEW, but will report back when I do, assuming you haven't found the solution by then.

How Do I Configure SSL for RAC Installation.

Experts,
Requesting your inputs on configuring SSL for my RAC environment.
- Oracle DB version is 11.2.0.2
- RAC is with two nodes.
- Two nodes are : rac1.oracle.com and rac2.oracle.com
- RAC setup has SCAN feature configured. SCAN FQDN : racscan.oracle.com
- All clients talk to RAC DB using SCAN feature as shown below.
client applications -> racscan.oracle.com ---> rac1.oracle.com
---> rac2.oracle.com
- tnsnames.ora file on both RAC instances has hostname as "racscan.oracle.com" instead of their individual phyiscal host names.
How do I configure SSL for RAC:
1. Do I need to generate certificate request for individual hostnames or only for SCAN hostname ?.
2. If I generate a certificate based on SCAN hostname, how does SSL work since SCAN hostname is not a phyiscal host name ?
3. What is recommended strategy for configuring SSL for RAC environment ?
Thanks

The documentation on the creation of Oracle Wallets is not specific to RAC, and the RAC SCAN instructions for TCPS are very vague on the specific requirements for the certificates required in the wallets for proper operation. I too am struggling to get it to work. Does anyone have a more technical guide to the specific configuration of the certificates needed and what specific configuration file changes need to be made?
Also, the self signed documentation is getting REALLY old. Oracle, please stop giving instructions that demonstrate irresponsibility and show the proper method of certificate requesting and importing to wallets.

How to uploade multiple flatfiles for single transaction using BDC?

How to uploade multiple flatfiles for single transaction using BDC?

Hi,
You need to upload all data files into an internal table first either using OPEN DATASET (application server files) or GUI_UPLOAD (PC files).
Then loop at the internal table and call BDC transaction to process the data.

12VDC for Limit and Home Signals for PCI 7334 using UMI-7764

Can 12VDC be used for Limit and Home Signals for PCI 7334 using UMI-7764.
Can the UMI 7764 be damaged if over voltage is supplied to it. If so can it be repaired or it has to replaced.

Specifications for the Limit Switchs (home, forward, reverse, etc) is
determined by the specifications of your NI motion controller PCI
board. The UMI functions only as a pass through and breakout for the
board .
The valid limit swich voltage for the PCI-7334 is 0 - 5 V. You will have to divide down a 12 V input before running it to
the UMI and to your board. The 3.3k pull up resistor is only used to
pull floating voltages to TTL levels and does not protect for high
voltage signals.
Please note that the UMI-7774 provides optical isolation for limit switches and extended input levels (e. g. limit switch voltages: On = 3.5 to 30 V, Off = 0 to 2 V).

Configure PXI-2567 to Trigger on Rising Edge using LabWindows/CVI

I need some help configuring the trigger edge for a PXI-2567 using Labwindows/CVI. I have been able to successfully create and execute a scan list using both the ni-switch and daqmx APIs. However, currently the PXI-2567 triggers on the falling edge of an input trigger. I need to configure it to trigger on the rising edge of an input trigger. Every function I could find in the daqmx API for configuring the trigger edge gave a non-fatal runtime error, and I could find no such functions in the ni-switch API.
Any help configuring the input trigger edge on the PXI-2567 using Labwindows/CVI would be appreciated.
Thanks

Hi JonRice,
You can configure the scan list to execute on the rising edge of an input trigger. Here are the Labwindows/CVI and LabVIEW functions you would want to use to retrieve, specify or verify the edge of a digital signal that advances to the next entry in a scan list.
NI-DAQmx C Property: More >> Advance >> Digital Edge >> Edge
You can get/set/reset this property using:
DAQmxGetDigEdgeAdvTrigEdge
DAQmxSetDigEdgeAdvTrigEdge
DAQmxResetDigEdgeAdvTrigEdge
NI-SWITCH C Attribute: NISWITCH_ATTR_TRIGGER_INPUT_POLARITY
You can get/set/check this attribute using:
niSwitch_GetAttributeViInt32
niSwitch_SetAttributeViInt32
niSwitch_CheckAttributeViInt32
NI-DAQmx LabVIEW Property: More:Advanceigital Edge:Edge
DAQmx Trigger Property Node
Short Name: Adv.DigEdge.Edge
NI-SWITCH LabVIEW Property: Trigger Input Polarity
niSwitch Property Node
Short Name: Trigger Input Polarity
Hope this helps! Let me know if you have further questions.
