PXI Switch Module

How do I detect the Switch module present in PXI Controller. I am programming in lab veiw RT 7.0 version.
I also need to find the device number and the slot info of the device present in RT controller programmatically.
How do I achieve this. Is there are any issues programming switch modules in Real time .
Suresh Thangappan

Suresh,
Your RT controller should have NI-DAQ 7.3 or later installed. Once NI-DAQ is installed, install your switch modules and restart your controller under RT. On your host computer, expand "Remote Systems", and under the IP adress of your RT controller you will see all the switches you have installed.

Which PXI switching modules won't degrade RS-422 communications?

I am developing a PXI-based application where multiple RS-422 busses exist whose signals can be monitored or traffic injected onto them. As such, the lines need to be switched between RS-422 modules and actual units under test. I don't want to introduce so much capacitance that traffic is degraded and engineering will blame their system issues on our test equipment. Is there a special family of cards that should be used, assuming that the baud rate doesn't go above 115.2 kbaud?
Dan

Hi,
If you choose a switch with a bandwidth say double of your baudrate it should not be a problem. Beside that in a testsystem you work with short cables so there is not much load to see for the driver.
I have a RS-485 application. To reproduce faults from the field I sometimes try to get the interface to fail wil resistive and capacitive loads. Try it you will be amazed how long it will work.
If the design fails because of the load introduced by the switch then I don't think it is gonna work in the real world with bad cables and/or connected devices.

Topology of PXI switch

Hi,
I am try to use PXI2527 300Vrms multiplexer card. According to "NI switches help", this module can also be used in independent topology. Does that mean I can have 32 insolated SPST channels instead of 32x1 multiplexer, and use all these channels at the same time? How can configure the module as this in MAX or by API?
Thanks.

Hello,
Yes, you can use 2527 in Independent Topology. You can do this from your programming environment such as LabVIEW. For example, you can use niSwitch Initialize with Topology.vi in LabVIEW to modify the topology of the switch.
To set topology of "Terminal Block" for the switch in MAX,
Expand Devices & Interfaces >> NI-DAQmx Devices >> PXI-2527. Right click on the switch module and select Properties. Then select topology from Terminal Block/ Accessory as shown in picture.

How Do I Configure the PFI Lines as input in PXI 6713 module

Hi,
I have PXI 6713 module in my PXI 1044 chassis. I have configured PXI 6713 module to geneate certain analogue signals to my board.
Board inturn process this analogue signal and responds back the status signals through a status register on the board. In my application,the status bits in status register of the board are mapped to the PFI 0:3 bits on PXI 6713 module ( pins 11,10 , 42 and 43).
My query is how do i configue the PFI lines as input in PXI 6713 module to read these status bits ??
May be below explanation could give you little bit more information w.r.to my query.
When i use NI USB - 6008 module to read the same bits , since this device has 12 digital I/O lines, i could able to read the status bits in to the last 4 digital lines by configuring the those digital lines as input.
In PXI 6713 module i have only 8 digital lines. These 8 digital lines i have used to send the digital signals to the board. I am left with no digital I/O lines. Hence i couldn't use these digital lines. I am left with only one option to use. Theya re PFI lines. Moreover the status bits in the pin out of board are mapped such that the bits can be read through the PFI lines.
I am wondering do we have any example code to use inorder to read these status bits on the board using the PFI lines.
Please let me know if you need additional information to help me out.
Thanks.
Solved!

Hello There,
When using the PFI pin as an input, you can individually configure each PFI for edge or level detection and for polarity selection. This PFI information can be referenced in the DAQ Analog Output Series Manual on page 6-1 (http://www.ni.com/pdf/manuals/370735e.pdf). Unfortunately, the PXI-6713 PFI lines are only capable of timing input and output signal for AI, AO, or counter/timer functions. The option of creating static DI from the PFI lines is not available for the PXI-6713. However, some cards have this capability. Newer National Instruments products with PFI lines have the option of setting PFI lines as:
Static Digital Input
Static Digital Output
Timing Input Signal for AI, AO, DI, DO, or counter/timer functions
Timing Output Signal from AI, AO, DI, DO, or counter/timer functions
(http://digital.ni.com/public.nsf/allkb/14F20D79C649F8CD86256FBE005C2BC4)
When set as static DIO, the PFI lines are assigned to a different port (eg. PFI0-7 is Port1). More details about this can be referenced at:

I need to measure the frequency of a signal on Pin 39 (PFI 15) of a PXIe-6361 module.

I need to measure the frequency of a signal on pin 39 (PFI 15) of a PXIe-6361 module. All of the digital I/O pins are already assigned and in use. The signal frequency range is 50KHz to 500KHz. I have tried all of the sample programs for DAQmx Counter/Timer frequency measurement. If I modify them to use my hardware, I get run-time errors with conflicts with resources already assigned.

Hi Julia,
Thanks for the response. As I stated before, I have tried all of the examples available that apply. There are only three and one of those uses two counters. The two I have tried are:
Examples/Hardware Input and Output/Counter Measurements/Digital Frequency/
DigFreq-Buff-Cont-ExtClk-ArmStart.prj and
DigFreq-LowFreq1Ctr.prj
These examples default to using what appears to be traditional DAQ hardware (Dev1/ctr0 and /Dev1/PFI0). I changed the counter to mine (/PXI1Slot3/ctr3) and directed my signal source (PFI15 on pin 39) to the counter. No matter what I tried would not run. They would always compile but gave run-time errors ranging from resources already in use to “external trigger required”. I have no external trigger source and, if I did, there is no indication of how to assign it to the counter. NI has a very good X Series Users Manual that tells all of the great things you can do with the hardware, but there is NO CLUE how to do any of those things!!!! I know that some NI DAQmx functions use hardware resources that they never tell you about. I discovered that when trying to produce a single output pulse from a timer using counter #0. (Which, by the way, no one at NI could tell me how to do it.)
Measuring frequency should be very simple. The unknown signal is routed through a precise gate to a counter, and then the counter is read. NI DAQmx uses the opposite approach of using my signal as the gate and counting their internal source. However, the examples would not let me use the internal reference sources.
To answer your other questions, I am not performing any other measurements at the same time and the counter is not being used for anything else, period.
Any help would be greatly appreciated. Thanks again.

BUG: Ctrl+Alt+ number to switch modules only works with number pad

Really annoying, since this worked nicely in the beta. If, for example, you hold down Ctrl+Alt+1 (pressing 1 on the top row of the keyboard) to switch to the Library Module, it doesn't work. If you use 1 on the numeric keypad, it works fine. What's the big deal, you ask? Well, try using the number pad on a laptop - you either get to use the number keys or the regular keys, so this shortcut is essentially useless on anything other than a full-size keyboard.

Windows treats Ctrl + Alt shortcuts as special. They are used as hotkeys for desktop icons, and if a key is used for that purpose, it overrides any use within a program. I did a little research, and setting a desktop hotkey to 3 will cause your LR symptoms, where you can't used the normal numbers and have to use the keypad to switch modules. On the other hand, you'd probably be seeing the effect of using the non-number-pad keys (they'd launch a program), so it's a mystery.
In my testing, I noticed that the Firefox browser uses that key combination to switch between its tabbed sessions. If you're running that program, you could test to see if it exhibits the same symptoms.

Can a broken Display Switch module cause my screen to not turn on or be recognized?

Hi All,
I have recently been having some issues with my LCD screen in my HP Pavillion dv9700. Ever since I replaced the left hinge on my notebook, I have had to fiddle with my screen by closing and opening it during booting to get it to turn on. This only happened when booting into linux. When booting into vista, the screen would turn on without a problem. This morning I was so fed up with this, that I thought maybe some switch was not getting pressed to tell the notebook that the lid was opened. After looking at all the cables and putting everything back together, my screen now no longer turns on no matter how much I open and close the lid. It wont even turn on in vista. I am however able to connect a vga cable to my notebook and use an external monitor without any problems. I opened up the nvidia control panel in both windows and linux and it does not recognize my notebook monitor, only the external monitor shows up. Could this be caused by a broken display switch module? How can I diagnose this problem? Is there a way to bypass the display switch module by jumping two wires?
Any ideas are appreciated,
Thanks in advance
OS: Latest version of Ubuntu Linux 11.10 dual booting with Windows Vista
Problem: LCD Monitor not turning on / being recognized
possible cause: LCD Display Switch Module

Update:
I just figured out that it cant be my display switch module because when i close the lid to my notebook, the external monitor shuts off and the computer goes into standby mode. I now think this might be an issue with the ribbon cable. Is there anything else which might be causing this problem which I am overlooking?

CSM-Content Switching Module

Hi All,
How to shutdown Content Switching Module in Cat 6500 switches ? I want to shutdown only CSM-Module without disturbing Chassis.
Can anyone please send me the command on that ?
Highly appreciate your valuable reply.
Thanks,

Hi,
Assuming you are using IOS, you can power-down a module in a 6500 chassis using the command
"no power enable module " in global config mode where is the slot number of the CSM.
If you are using CatOS then the command would be:
"set module power down "
The CSM should be hot-swappable so you should be able to just pull it out of the chassis, but I think that is a bit vicious if you only want to shut it down.

Function not found in library? 1127 switch module

I am trying to control individual relays in an 1127 switch module with a 1331 attached. Whenever I try to connect to it through the block diagram (or through example programs) I get an error stating "Function not found in library" or sub vi not executable. However when I try to control it from the switch executive front panel it seems to work correctly. When I follow the sub vi error chain I eventually arrive at the library node and I am told to configure it. However when I click configure I get options that are phrased slightly differently than the original sub vi name. How do I get the example code / control over the 1127 installed in an scxi chassis.

Raaron,
The SCXI 1127 is a Matrix / Multiplexer card. If we wanted to try to make it function similar to an SPDT, you will limit the number of "SPDTs" you can create. With the 1331 that can only be configured as a multiplexer and essentially used for a single "SPDT" [com(SPDT) = com (Mux), NC(SPDT) = Ch0 (Mux), NO(SPDT) = Ch1 (Mux)] . If you use the 1332 you have a 4x8 Matrix and can make it into 4 "SPDTs" [com(SPDT) = r0(Matrix), NC(SPDT) = c0(Matrix), NO(SPDT) = c1 (matrix)]. Both of these configurations will not really be normally closed, and you would have to configure it in software to close when you are using it.
If you are looking for a true SPDT I would look at the 1160, 1161 and 1166.
I am glad that it is working now, but I am still confused as to how you were having SW issues though. Maybe the device was being set up as a Traditional DAQ device and was installed on an OS that does not support Traditional DAQ? Resetting the device [for DAQmx use] may have fixed this? I am unsure without further information.

1800 series switch module IP address

Newbie question, can the switch module on the 1800 series router be assigned it's own IP range like any other interface?
Cheers

You define vlans on them, and each vlan can be configured with an interface.
Or to each port you can say no switchport and configure each port as a layer 3 interface (with ip address).

WAE Inline Deployment on a router intergated switch module

Hi,
Is it possible to simulate an inline WAE deployment on a router with an integrated switch module?
Thanks.
Ed.

Ed,
Unfortunitely you have to use WCCP or PBR with NME-WAE. Inline is only possible with the inline card on an appliance.

Can you Connect Cisco switch modules for to N2K?

I have not seen anything about connecting Cisco Switch modules for Blade Chassis to fex. Does anybody now if you can do that?
thank you.

thank you Lucien.
I think you got a right name for N2Ks, a NIC card extender. In my opion N2K should be able to support Blade switches. Not every company has just rack mount servers, most enviroment is mixed. In my case, I run out ports on N5K, but plenty available on N2K. I want add two more blade centers with gig switch modules in them. now I have to buy a N5K!!!. I'm sure Cisco can make N2K to support switches too.

IP changes on a Cisco Switch Module for IBM BladeCenter

Hi everyone,
I was just wondering if anyone out there is using the MDS modules for IBM BladCenters and if so whether you had had any problems changing the IP details through the BladeCenter management interface. I needed to change a subnet mask but since making the change I've lost all IP connectivity to the module and it shows Status: Disabled under the new IP Details.
I've tried resetting the module to factory defaults and whilst this seems to have had some effect (e.g. the fc ports have all gone down) it has given me any IP connectivity or allowed me to set up a new IP address.
Has anyone else seen this and if so, how did you get round it.
Thanks,
David

Hi Mike,
I saw that it doesn't allow you to change any of the IP config through the CLI, hence why I moved on to trying the MM.
Fabric manager can't connect to the module on it's address (I was just correcting the subnet mask) and it is not pingable from anywhere on the network, so it seems to me that the IP path out through the MM isn't working.
I tried the same process on one of our test chassis and the same thing has happened there.
Configuration for that slot looks like this on the MM:
Bay 3 (Fibre SM)*
Current IP Configuration
Configuration method: Static
IP address: 172.20.221.9
Subnet mask: 255.255.255.0
Gateway address: 172.20.221.3
New Static IP Configuration
Status: Disabled
To change the IP configuration for this switch module, fill in the following
fields and click "Save". This will save and enable the new IP configuration.
IP address 172.20.221.9
Subnet mask 255.255.255.224
Gateway address 172.20.221.3
How does the MM communicate with the module (telnet/snmpv1/snmpv3/ssh?) and with what credentials. I'm thinking that there must be something in how we've configured the switches that is breaking this in some way (we've enabled aaa auth for login, removed some default SNMP details, and disabled the telnet server).
There seems to be rather a lack of docs on these modules, is there anywhere to find out more detail on how they all hang together.
Thanks for your interest and help,
David

Cisco 2951 poe limitation for switch module ?

Hi , i have cisco 2951 router with switch module :
SM-D-ES3G-48-P
there are many poe devices connetced to the switch module .
the problem we face is , sometime the poe devices get down and up (flapping)
after investigatipon by command
show power inline police
i found the devices is getting about 60 Watt , and there is remaining power about 200 watt.
the question is , how to investigate and troubleshoot this issue ?
is there any limitation in the power for that platform ?

Hi ,
thanks for reply
the issue is :
interfaces get down , then up
some times it still down and take long time to be up agian !!
exactly if i did shutdown , then no shutdown
thats the problem that we face !
sorry cant access the swith now , if i can i will post the config i have.
