Serial cable problem

serial cable working well but when i connected serial cable to my circuit board it can not take data from my my microcontroller in which i burn a program and that program should display on the lab view example basics serial read and write but it is not display the program on lab view i also replace microcontroller, max 232 ic bubber ic 74ls244 but it is no use please help me and thanks alot in advance.

I'm sorry, but I'm confused as to what you're saying now. You had said that it worked with HyperTerminal. Now you seem to be saying it doesn't. Let's keep LabVIEW out of this for the moment. Can you communicate with your board with HyperTerminal? That means you actually have the cable connected to your board and you're talking to it via HyperTerminal.

I need to use agilent34970A with serial cable;but i'm not able to build a routine.

Hi, i'm learning labview and i'm not able to build a routine to communicate with my Agilent34970A with serial cable only and to use the data. Anyone can help me? thanks. lucky

Are you using the driver from the LabVIEW Instrument Driver CD or that you downloaded from here? If you are, what problems are you having? Are there error codes generated and what are they? Have you verified that the serial cable is correct and the the comm parameters (baud rate, stop bits, etc.) are the same in the program and the instrument?

You can use this : http://www.macupdate.com/app/mac/51344/serial but let me tell you that last night I found the way to do it with Coolterm for free http://www.macupdate.com/app/mac/31352/coolterm
I think that the problem is the installation , you have to copy to sudo kextload /System/Library/Extensions/ProlificUsbSerial.kext or in my case I used this as reference, now it is working....

How i can connect the pci nican card with stoeber posidyn sds 4021 via serial cable

i'm trying to communicate the stoeber posisyn sds 4021 servo inverter and the pci ni-can card via serial cable. the problem is that 1 RxD and 2 TxD pins dont have any connection available on the can card.
it is important to connect these pins somewhere or can_l and can_h do all the job?
what about the v- terminal, it is possible to connect it in grnd and leave v+ with 8v?

In this situation it may be necessary to contact the manufacturer of this device. It is strongly recommended to use both CAN_H and CAN_L for CAN communication. The V- pin is used as reference ground. The V+ is simply for bus power.

V100 goes to ok when serial cable disconnected

Hi,
I have 2 V100's at work that I have connected to a one of our Dell servers. The V100's are connected via serial cables to com1 and com2 on the Dell. I have them constantly connected because I can get into the dell via Terminal Services if there are any problems (I am the only UNIX admin here and trying to walk someone through booting up or fixing a UNIX box is too much when I can just do it myself). So, here is m problem. Last night one of the windows admins reset the dell server and both of my V100's dropped to ok>. I assume they noticed a change in the serial connection and thought I wanted to do maintenance. I know it is easy enough to just go into each via hyperterminal and type go but I would like to stop this all together. Does anyone know how I can do this?
Thanks

In /etc/default/kbd, uncomment the following line:
#KEYBOARD_ABORT=alternate
This will hang BREAK sequence to "<RETURN>~^B" - Actually I'm pretty sure the <RETURN> isn't required but the docs say its part of the sequence. This will prevent your Sun's from going to the OK prompt when the Dell's drop.

My iPhone 4 is no longer recognised by my laptop, and no longer registers being plugged in to charge, even though it will charge slowly if plugged in and turned off. It's not a cable problem or a computer problem, as I've checked these.

Hey, over the past couple of days my iPhone 4 (GMS, Model A1332, EMC 380B - running on iOS 7.1.2) has begun inexplicably intermittently not recognizing being plugged in to charge or being connected to my laptop. As of today, it has complete stopped recognizing being plugged in to charge or connected to the laptop.
If I plug it in to charge, whilst it is on, nothing happens and the battery drains.
If I plug it in to charge and turn in off, it will charge very very slowly - though it will charge fully after a long time.
When I connect it to my laptop, nothing happens - it doesn't appear in iTunes, and it doesn't charge or recognize being connected to the laptop (there is no charging symbol, no noise from either phone or computer registering the connection as it usual did, or another sign of any connection between the devices, though, again, it will charge very slowly if turned off).
I've ruled out the possibility of it being a cable problem, by using a friend's cable and finding that didn't allow it to recognize being plugged into the wall to be charged either, or being plugged into the computer.
My friend's cable does work on their own iPhone (ie, when plugged into the wall with their cable, their iPhone acknowledges this and charges properly, and when plugged into my computer with their cable both my computer and their iPhone recognize the connection).
So, it's definitely a problem with my iPhone itself, but I don't know what.
As I say, it will charge very slowly, if it's switched off whilst it's plugged in, but it won't acknowledge being plugged in, and will only drain if it is turned on whilst being plugged in - and it will not recognize being connect to my computer.
Please help me figure out what is wrong with it, as this is beyond annoying and I'm literally banging my head against the wall - the iPhone is little over a year old.
Cheers.

try a reset of iPhone and then a restore,best, as new and if it then functions correctly try restoring with your backup

Aperture 2 install - serial number problem

Disclaimer: I'm pretty good on a pc. Absolutely terrible on Mac, never had so many problems with tech :/
So...I have my serial number from the back of the Aperture 2 "Installing your software" booklet. Checked that I'm entering "I's" not "1's." Got dashed between the sequences. Capslock on etc. Searched forum, quite a few posts on serial number problems. None matched.
Enter serial number. Second window pops up stating I've entered an upgrade serial number (I only have the expired trial version of Aperture installed), and requesting my "serial number."
I'm lost now. Checked my original docs, there's nothing on Aperture trial version. Fired up the trial and I see what looks like a license key (to Apple, not me) on the launch screen. That's not accepted by Aperture 2.
Any thoughts on this appreciated.

Thanks, think you solved this Wish the label said something like that, the box only says Aperture 2, not upgrade license. So I'm guessing I have to pay $199, and keep this $99 package to upgrade it? I hope not. I'll ask at the store.
There is a tiny label on the bottom edge of the box. Mine says "Aperture 2.0 Retail". The tiny label on my box for Final Cut Express 4 says "Final Cut Express 4.0 UPG". Does yours not say "UPG" on that little label? If not, you should be able to return it for the full version (plus pay the difference, of course). If it does say "UPG" you might be out of luck as most open software can't be returned.

Thunderbolt display video died-Cable problem??

My TD (paired with a Retina) video seems to have lost its video. Audio working fine. Could this be a cable problem?

I can confirm that the Thunderbolt Display will work when plugged in to the 2011 MacBook Pro 15" and a 2011 Mac Mini Server connected via Apple's Thunderbolt cable. When both systems are connected to the monitor, the display will always prefer the system connected to its display port, when it sleeps or is powered down, the other system detects the available display and connects to it automatically. I can't imagine a more ideal sinerio!
Thank you Apple!

Solaris 8 says: "Link down, Cable Problem?"

I have these on my home LAN:
1. Sun Ultra 5 Solaris 8
2. Win 2000 PC
3. Win NT laptop
They are all hooked into a LinkSys Router.
The Router is hooked into my Motorala Cable Modem.
Here's the problem:
The PC and the laptop can see each other on the LAN.
The Solaris 8 is only visible on the Lan INTERMITTENTLY.
The lights on the Router for the PC and laptop are always ON.
When I reboot the Solaris box, the lights on the Router sometimes come ON, and sometimes they stay OFF. When they stay OFF, I see the message: "Link down, Cable Problem?" during reboot.
I have tried different cables, and tried various combinations of the 4 avalable ports on the back of my Router.
If I plug in the Sun box DIRECTLY into my cable modem, then I don't see the above message. (but then I don't have a LAN anymore)
Please help, I've been struggling with this for a while now.
Thanks,
Irshad Ahmed (I am relatively new to Sun)

Hi
You have not indicated if you have the router ethernet ports working
at 100Mbps or 10Mbps. Depending on this sometimes, Sun systems may
not be correctly auto-negotiating their ethernet port settings.
You may set these parameters to force Sun Ultra 5 to a 100Mbps mode or a 10Mbps mode.
For forcing it to 100Mbps, Full Duplex mode and disabling the auto-negotiation, put these entries in /etc/system:
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0
Conversely, if you want to force your Sun to work on 10Mbps, Full
duplex mode, (if your router does not support 100Mbps) in the same
/etc/system file, put the following entries :
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=0
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=1
set hme:hme_adv_10hdx_cap=0
One of these should solve your problem. You need to reboot the system
after putting these entries.
You can also check the port at the OK prompt using the command
"watch-net". This test the onboard ethernet interface.
You may also apply the hme patch released by Sun that fixes many
known problems with hme ethernet driver. The patch id is 108981-03.
It is available from the site :

Serial-to-serial cable. Does it exist?

I would like t interconnect two cisco routers for testing purposes, using their serial ports, but still can not find serial-to-serial cable (60-pins each side).
Should i make such cable by myself? And where can i get pinout for the cable like this?
Thanks!

HI Seri,
You can connect 2 routers via back to back connection using srial ports. Need to have DTE to DCE connection.

Hme0: Link Down - cable problem?

i've a problem i've buyed an ultra 10 (used)
i've reinstalled solaris 10 01/06
when it boot the o.s. it give this error message "hme0: Link Down - cable problem?"
and network don't work.
i cannot ping my router but i've gave to my sun an ip of the same netmask (sun ip 192.168.1.88 router ip 192.168.1.1)
i've checked the cable and it's good (it work with a normal pc)
the led on the switch is on (it's green)
maybe i need some patch
how can i do?

gio,
You didn't necesarily do anything wrong.
You do not necessarily have any broken equipment.
There may just be somthing that is incomplete in the setup.
Begin by checking if your network settings were set up correctly by running:
# ifconfig -a
(it's usually best to troubleshoot while you are root user)
If the output from the ifconfig command seem to be complete, you could always think about reconfiguring the NIC all over again.
If you are not sure, then just paste the entire output results back here.
Also, use the forum search function, using keyword sys-unconfig.
Next, read the Solaris man pages for sys-unconfig.
That command will force you to repeat the setup of the connection.

Howto Link Down-Cable problem?

Hi,
I am having a Ultra Sparc 5 with a hme interface and a quad card. When the machine boots it checks at boot prom level all 5 interface and reports for all qfe interfaces "Link Down-Cable problem?". All qfe interfaces do not have a ethernet connx but I also do not want to deinstall the quad card. Is there any possibility to turn thoose "interface checks" off.
Thanks Marcus

Never mind I just figured out that thoose checks just run after the boot cdrom command.
