Help with internal signal routing on a 6602
I need to do the following with a 6602:
GPIO (any) to RTSI0
4 Counter Outputs to RTSI1-4; doesn't matter which.
I have tried P0.0->RTSI0 and then CTR0-3 to RTSI4. But I get an error that the resources required for the last connection (CRT3_OUT -> RTSI4) are being used by the P0.0->RTSI0 route.
What are the rules? Acording to the routing chart, they are all possible, but I don't know how to keep them from bumping into one another.
Hi:
How is it that you are doing the routing? DAQmx eport signals? DAQmx connect terminals?
Can you give us a little bit more background on what you are doing?
Have you this article or this other?

Will an Airport Express help with the signal I am not receiving on my Smart TV?
Will the Express help with internet issue's I have with my new Smart TV?
If you already have another Apple AirPort router that is providing your wireless signal, then a new AirPort Express could extend that wireless signal to provide a stronger wireless signal to the TV....assuming that the TV connects using wireless.
Is this what you are asking?
Or, would the Express provide other services to "help"? -
Need help with internal HD memory problems when using Premiere Pro?
When using PP I keep loosing memory on my HD.
Now this seems strange to me since I have every thing, all my video and audio files on external HDs.
Each time I time I make a new project I end up with less space on my internal HD.
Information related to these projects is somehow remaining on my internal HD.
Anyone got any ideas about what I might be doing wrong?
DimitrijePremiere will slowly compile various files to help the project along, and the default place is usually your internal hard drive. Make sure your scratch disks are pointed to an external hard drive if that is what you want, also, make sure the Media Cache Files are being created on your external as well (and not the default location which is on your local drive).
Premiere Preferences > Media
Media Cache Files & Media Cache Database should be changed to an external disk if you don't want them created on your local disk. There are many tutorials and explanations about all of these aspects of Premiere on these forums and from other sources. Hope that helps! -
Hi, anyone can help me with my password for the WRT54G router. I am trying to reconfigure it, but is asking me for a password. I reset the back bottom, and I entered "admin", but still does not work. It does not go on with the set up.
Thanks, MaribelWelcome to the Cisco Home Community.
Type 192.168.1.1 on your browsers address bar.
When prompted for a password, leave username blank and type admin in the password field.
Enter your configurations.
Do post back for any updates.

Help with international settings - the menu bar flag is gone!
The flag no longer appears in my menu bar, nor does the "show input menu in the menu bar" check box in the international section of the System Preferences stay checked. I no longer seem able to type in Chinese, which is what I really need to be able to do.
Help? Thanks!Hi Crimsoncat and welcome to the forums!
Seems your Chinese has been taken away...
(Sorry, just could not resist!)
Now for solving your problem! When did this start happening? Have you tried a bit of maintenance, like:
Repairing permissions is an important part of regular maintenance, and should always be carried out both before and after any software installation or update.
Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
In First Aid, click on Repair Permissions.
This only takes a minute or two.
Background information here:
http://docs.info.apple.com/article.html?artnum=25751
and here:
http://docs.info.apple.com/article.html?artnum=302672
An article on troubleshooting Permissions can be found here:
http://support.apple.com/kb/HT2963
If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.

Hello,
I have tried multiple attempts at writing rules that absolutely block international spam. Seems most of it is in French. I've set rules to delete mail with certain characters, etc. Nothing seems to work. I just want the Mail application to delete each one, not even show up in my junk folder. Any help would be greatly appreciated.I haven't found a decent solution to foreign-language spam other than to use a bayesian anti-spam filter such as SpamSieve.

It's well worth the price, IMHO.

Help with simple interVlan routing on L3 switch
Hi all - I just can't get my head around this really simple interVlan routing issue. I have two VLANs (1 & 6) on a 3560 L3 switch. I simply need to route between them. Here is how I have it set up:
Firewall is the VLAN1 client's default gateway:
10.10.22.1 /255.255.255.0
3560switch config:
ip subnet-zero
ip routing
VLAN1:
(hosts on 10.10.22.x/255.255.255.0; gateway 10.10.22.1)
int vlan1
ip address 10.10.22.254 255.255.255.0
no shutdown
VLAN6: (hosts on 192.168.25.x/255.255.255.0; gateway 192.168.25.1)
ip address 192.168.25.1 255.255.255.0
no shutdown
ip classless
int gi0/31 (an available unused port)
no switchport
ip address ?.?.?.?
no shutdown
Is the issue that all my 10.10.22.x clients are going to 10.10.22.1 trying to find 192.168.25.x, when they would need to go to 10.10.22.254; then the switch should have an ip route of 0.0.0.0 0.0.0.0 10.10.22.1? Then give the router on gi0/31 the 10.10.22.254 address?
(as a side note, it would be easier for me to change the gateway's IP than to change each VLAN1 client's IP.)

Hi,
With the above configuuration vlan 1 users will be going to firewll and if they want to reach vlan 6 firewall should have rule to permit for vlan 6 subnet and route towards vlan 6 interface and which is not there is your network.
Just clarify few things you want firewall to come into picture for every traffic which goes between vlan or not and in interface gi0/31 you will be connecting router also is this router is sending traffic to outside world if yes then you need to change some design configuration to route tha traffic from vlans to outside world.
If you want only inter vlan routing between vlan 1 and vlan 6 via firewall then make another zone in firewall and place that in vlan 6 with ip address as given in vlan 1 so that vlan 6 users can point traffic towards vlan 6 interface of firewall and in firewall just permit the vlan 6 communication with vlan 1 and drop a route for vlan 6 towards switch vlan 6 interface.
and if between vlans you dont want firewall to come into picture then the best is create three vlan one for vlan 1,vlan 6 and outside vlan between router and firewall and drop a default route towards firewall.In this case inter vlan routing will be taken care by switch and traffic towards outside world will scaaned as per rule given in firewall.
Hope to help

I'm working with 1080i HD footage (captured from a Canon HV30) and output through an Intensity Pro PCIe card to a 1080p display while working on Final Cut Studio 2. I have two separate monitors outputing 1920 x 1080.
I'm working on a 2.8GHZ Quad-Core Intel Xeo Mac Pro with 10GB of RAM and a 320GB Hard Drive. Quicktime stumbles over 1080 footage from FCP, skipping frames, so I need to stripe some drives, internally if possible (there's three slots available for drives).
I already own an additional 1.5TB SATA hard drive, and am wondering...
What size drives would be ideal to handle 1080 footage? Would 500GB drives be enough, 1TB, or 1.5TB? Should the drives all be the same size?
Do I need a PCIe card to stripe these drives together or is the OSX Disk Utility sufficient?
Will I need to stripe three drives, or is two sufficient? Should I stripe together the main drive too or stripe the drives separate from the main hard drive?
Help on any one of these questions would be appreciated. Thanks for reading.Ok, now that you have freed up some space on your system HD, the next thing would be to do a little system maintenance.
First, shut down your Mac and restart it. Don't just log out. Shut it down. Power it off. Then restart. In System Preferences, turn off Time Machine if you have it running. Also put your system HD in the Spotlight privacy list (aka System Preferences > Spotlight > Privacy > Prevent Spotlight from Searching These Locations.)
Then, if you don't already have one, download a utility like Cocktail, Onyx, MacJanitor, etc. and run it. (You have Leopard, so make sure you download the appropriate version of the utility.) Make sure there are NO other applications running when you run the utility. When you run it, accept all the default operations and also check the option to clear the system cache; you want to clear the system cache. Also set it to shut down your Mac after running. (If there is no such option, you should manually shut down your Mac after the utility runs - and I mean shut down, not just log off.) The first time you restart after running the utility & clearing the system cache, your Mac will take longer than normal to boot; don't worry, that only happens the first time, as your system will be rebuilding the system cache.
Next, you should probably delete any render files that currently exist and re-render your video.
Then try exporting your video again, and see what happens. -
Routing Experts please help with below LAN routing issue with NAT
Hello Experts,
I have a weird situation and requirement.
The existing setup is -
We have email/ticketing server hosted in the LAN which is reachable on the publicly NAT'ed IP with respective port numbers of 89 & 443. We have LAN & servers on the same subnet. The internet is with public DHCP IP assigned by ISP (/29). We use linksys router GUI for NAT settings (attached).We are using the same public IP for the server NAT & user NAT.
We tried to refresh our network by separating the subnets for LAN users & servers. We used the Cisco 3845 router to create sub-interfaces in the LAN and configure respective subnets. Now both user subnet and server subnet are connecting to the Internet with same public IP (static NAT for servers & dynamic for users). We can connect to the server IP from the Internet and it resolves fine. However user LAN subnet cannot connect to the server if we try the URL. Users can access the Internet fine.
Please find attached short diagram and below configuration and please give your inputs to solve this.

DeepakOne more thing I should clarify the route I am putting into the 10.10.1.9 server is
route add 10.1.6.0 mask 255.255.255.0 10.10.1.250 which tells the server to bypass the ASA and go directly to the ISP router.(then i can successfully tracert everything). The big question here is how to make the inside ASA connection 10.10.1.1 to force all traffic to 10.10.1.250.
Thanks in advance. -
Help with Internal table - Urgent Please
I had an internal table declared as below:
DATA: BEGIN OF i_results OCCURS 0,
pernr like p0014-pernr,
begda like zhrccroll-begda, "Cost center roll out begin date
endda like zhrccroll-endda, "Cost center roll out end date
aedtm like p0014-aedtm,
uname like p0014-uname,
kostl like p0001-kostl,
ittype(7),
END OF i_results.
And my SQL to populate the table based on some other results:
select t1pernr t3begda t3endda t1aedtm t1uname t2kostl
appending corresponding fields of table i_results
from pa0014 as t1
inner join pa0001 as t2
on t1pernr = t2pernr
inner join zhrccroll as t3
on t2kostl = t3kostl
for all entries in i_it01
where t1~pernr = i_it01-pernr
and t2~kostl = i_it01-kostl
and t3~kostl = i_it01-kostl
and t3~syst = 'STAFF'
and t1~aedtm = p_date
and t1~uname in so_name.
Everything was working great and now user wants to see additional dates on the report so I have to add couple of dates to internal table but unfortunately they have same names (begda, endda), Now I need internal table like this:
DATA: BEGIN OF i_results OCCURS 0,
pernr like p0014-pernr,
begda like zhrccroll-begda, "Cost center roll out begin date
endda like zhrccroll-endda, "Cost center roll out end date
aedtm like p0014-aedtm,
uname like p0014-uname,
kostl like p0001-kostl,
begda like p0014-begda, "infotype begin date
endda like p0014-endda, "infotype end date
ittype(7),
END OF i_results.
I cannot have duplicate declarations in internal table and also my SQL would not work. The new SQL would be:
select t1pernr t3begda t3endda t1aedtm t1uname t2kostl
t1begda t1endda
appending corresponding fields of table i_results
from pa0014 as t1
inner join pa0001 as t2
on t1pernr = t2pernr
inner join zhrccroll as t3
on t2kostl = t3kostl
for all entries in i_it01
where t1~pernr = i_it01-pernr
and t2~kostl = i_it01-kostl
and t3~kostl = i_it01-kostl
and t3~syst = 'STAFF'
and t1~aedtm = p_date
and t1~uname in so_name.
This is not working either.
Could comeone please help me how to acheive the desired result. I am trying to get all the data in one shot, and that is why I have the SQL above. Any ideas you could provide would be greatly appreciated.
Thanks in advance.
MithunHI Mithun,
To add to vishnu do not use "appending corresponding fields of"..
1) if you are reading this data again and again then use
"appending table itab"
2) if it is triggered just once then use
"into table itab"
And also define ur itab as:
DATA: BEGIN OF i_results OCCURS 0,
pernr like p0014-pernr,
ccbegda like zhrccroll-begda, "Cost center roll out begin date
ccendda like zhrccroll-endda, "Cost center roll out end date
aedtm like p0014-aedtm,
uname like p0014-uname,
kostl like p0001-kostl,
begda like p0014-begda, "infotype begin date
endda like p0014-endda, "infotype end date
ittype(7),
END OF i_results.
and your select statement as:
select t1pernr t3begda as ccbegda t3endda as ccenda t1aedtm t1~uname
t2kostl t1begda t1~endda into table i_results
from pa0014 as t1
inner join pa0001 as t2
on t1pernr = t2pernr
inner join zhrccroll as t3
on t2kostl = t3kostl
for all entries in i_it01
where t1~pernr = i_it01-pernr
and t2~kostl = i_it01-kostl
and t3~kostl = i_it01-kostl
and t3~syst = 'STAFF'
and t1~aedtm = p_date
and t1~uname in so_name
I am sure you need to tweak and twist the above statements a bit..
Hope this helps..

Help with RV042 Static Routing
I just purchased an RV042 Dual WAN Router. Both WAN's are connected from different ISP's. I have a PBX phone server connected to this router and want all traffic to and from this phone server going out strictly on one WAN and all the computers and the rest of the traffic on the other WAN. If I understand correctly, this needs to be set up in static routes? If that's the case, how would I do that? If not, the question still stands. Please help.
Hello Vitaly,
What you are looking for is Protocol Binding. By setting this up you will be able to control what traffic goes out which WAN port. Protocol Binding can be done for certain traffic types or for certain IP addressess. -
I need the address that you go to for setup on the router. Can you help?
This is to be done on a PC wired to your router :
Click Start >> All Programs >> Accessories >> Command Prompt...A black box will appear(Command Prompt)...In the Command Prompt window type ipconfig and press 'Enter'...Look for Ethernet Adapter Local Area Connection IP Address , Subnet Mask and Default Gateway...The Default Gateway is the IP Address to go to the set-up page of a router... -
i have a scaled input from the daq device which varies from 0-200.
i need to detect sudden signal falls.
but the signal is fluxuating and is read every 100ms. but its fluxuating values limit me from using Peak detector vis.
i made a vi which detects sudden fall of values. it monitors last 5 points and if the difference negative, it's considered as a signal fall.
please have a look at the vi attached.
Kudos always welcome for helpful posts

I need help with my WRT54GS router.
My WRT54GS linksys router is acting up pretty bad. For example, i am just surfing the web and i have a program Ventrilo going talking to some friends, then all of a sudden i get disconnected from it and my internet just suddenly halts and then reconnects in a mere second or two. it also does this in the middle of me playing my online games. I have done every solution that i thought would remedy this problem, getting an ethernet cable, reinstalling Linksys, restarting my modem and router, changing my internet's security, reinstalling vista on my computer, EVERYTHING. I am not alone in this, my brother, plays the PS3 online, and my other brother plays a computer game on his computer. Anyway, while we are all doing our things on our own computers, we all get disconnected from the internet at the same time and it happens pretty frequently about once every 10-12 mins or so. Is anyone having the same problem, or does anyone have any ideas/solutions to this problem?
Message Edited by Vaun1992 on 02-23-2009 03:02 PMYou need to reset and re-configure your router to see if that makes any difference...Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
If you still face the same problem you should try to upgrade your router's firmware...
Download the Firmware from here ,
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
If you still face the same problem you should connect one computer straight to the modem and check if you have stable internet connection or the same problem re-occurs... -
Help with digital signal processing app
I have been programming in CVI for nearly 7 years now, using general purpose
National Instruments DAQ boards.
I have an application where I need to mimic an analog processing stage digitally,
obtaining the same results as the analog processing. The analog process
is a simple filter, but I'm not sure the best approach: a filter or perhaps
an FFT? If a filter, which type? The digital processing needs to be done
in real time, during the acquisition process.
Thanks!Thanks KlausJJ, my program can now identify frequency magnitudes of a sound. I struggled a bit with the FFT, then i changed the FFT code i had mentioned earlier, and used another one, and it's working fine.
I now have another important question. I want to identify a clap sound. I'm not sure how to do this. I'm not sure if i should use FFT or not. If i want to compare a sound patterns produced by a clap, do i compare the frequencies or simply the clap waveforms. I'm thinking i can compare the frequency magnitudes of the claps for the frequency ranges. What i wanna do is get the 20 highest frequencies of a clap, and see if another sound is a clap by looking at its 15 highest frequencies. If those 15 freq ranges are present in the original clap's 20 highest frequency ranges, then i confirm that it's a clap. Or maybe i should compare the 15 highest and lowest?
Is this method effective? Or is there a better way of comparing patterns?
Thanks.
