Dropped commands via ethernet connection

Hello,
I seem to have commands dropped whenever I use ethernet connections as opposed to GPIB or RS232. I do not know if it is due to timing but depending on the instrument the more frequent the dropped commands occur. If I highlight the execution, I see the data flow as expected and commands. I have tried placing timeouts before and after/delays in between commands, even *OPC, to make sure the operation is complete before moving on to the next command.
This question is very general for very specific pieces of instruments but I am convinced it is due to the ethernet connection and my understanding of the timing of commands.
Thanks,
Christian

Some instruments just need time to process commands before they can accept any more. The Ethernet tends to send data faster, but also has a higher latency. You could be running into this latency issue. In general, you should have waits between commands just for allowing the instrument to process it, regardless of the communication bus.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

I want to transfer files from a Win XP PC to a Mac using Time Capsule via Ethernet connection. Is this possible?

I want to transfer files from a Win XP PC to a Mac using Time Capsule via Ethernet connection. Is this possible?

Sure.. the PC connects by SMB.. the Mac connects by AFP or SMB..
But you can simply share SMB directly from the Mac.. there is no need to copy files through the TC. Go to system preference, sharing, and turn on SMB for the folder you want to share files to / from on the Mac.
Make sure you have a common username and password also helps.
If you have a TC already can you copy files to it via the windows machine??

I want to connect a Windows PC to an existing Airport Extreme router via ethernet connection. Is there any utility required or can I just plug into the router?

I want to connect a Windows PC to an existing Airport Extreme router via ethernet connection. Is there any utility required or can I just plug into the router? The router is already set up and working with existing iMacs.

thanks for the info. I found apple utilty software on this windows 7 PC but I guess it is not required for sharing internet on exisiting apple extreme. Am I correct that I can remove this apple software?

AirPort Express Dropping Connection to AirTunes via Ethernet Connection

I connect to my AirPort Express via ethernet using iTunes and AirTunes. I am using Windows Vista. The device works great for roughly 15 or so minutes, and then seems to loose its connection with iTunes. iTunes continues to play the music, but there is no sound coming out of the audio device connected to the AEx. If I toggle the Computer Speaker/AirPort Express output selection in iTunes it reconnects successfully with my AEx and will work as expected for a period of time, and then will eventually drop the connection (or at least the audio stops) again. I've used my AEx successfully for a couple years now - something over the last few months changed as this behavior is new. I am using the latest firmware and the latest version of iTunes.
Anybody have any ideas? Are there known software/firmware compatibility issues?

See http://discussions.apple.com/thread.jspa?threadID=1949393&start=0&tstart=0
This might be the same problem you are having. There is no fix as of yet.

How can i connect/disconnect PPPoe via Ethernet connected time capsule??

I connected the time capsule with Ethernet.
I set connect to PPPoe with "Manual" option.
I could easily control "Connect/disconnect" pppoe using AIRPORT (in the menu bar). But I could not find a way to "Connect/disconnect" via ETHERNET. (No ETHERNET icon on menu bar anyway...)
Could somebody help? THanks a lot.

Have you consulted the printer's user manual for setting it up as an Ethernet printer? You will also need to delete your current printer in Print & Fax and when you Add the printer you will need to do so as an Ethernet printer. This means you will add it either as an IP printer using either LPR or IPP protocol - depends on what the printer supports. An Ethernet device requires an IP address that is either manually configured on the device or derived if the device supports DHCP. If the former then the IP address you configure for the printer must be within the range of IP addresses used by your router (typically 10.0.1.2-10.0.1.199 for an AEBS/TC.) This should be covered in the printer's user manual.

E2000 setup via ethernet connection for a Mac?

Hello!
I recently purchased a Mac and wanted to reset my wireless router and set it up using my mac. However, when I downoaded the software to set it up again, it said it was not compatable with my Mac OS (X Lion 10.7.4). I am sure there is a way to manually set it up via an ethernet connection, but I am at a loss as to how to do that.
The wireless router is working just fine, I am able to connect to the internet wirelessly and there's nothing wrong with my internet service, however the wireless router is not secured.
I have my Mac connected to the wireles router via an ethernet cord, but have no idea how to proceed from here.
Any and all help would be greatly appreciated!

Hi there. True, for E2000 router, there is no update for Cisco Connect that is compatible for mac 10.7. And yes, you can do it manually to secure your wireless network. Good that you plugged-in your mac to the router. Open your internet browser (Safari or Firefox). On the address bar type in http://192.168.1.1 and press enter. It will usually prompt you for a username and a password. Try admin in both fields. If it will not work it means it has been setup to something else. If you have any notes already about router log-in password then use it. Usually, when admin works it will take you to the set-up screen. From there you click wireless on the black bar and go to wireless security subtab on the blue bar. You can select WPA/WPA2 mixed mode. After selecting it, you will see an empty box for passphrase and that is where you can type your wireless password (minimum of 8 characters, no special characters no space). Make sure to save it. Now open your wifi and connect to your secured network. It means connected when it has a tick or check mark before the name and that is after you typed-in the password.
If ever, admin did not work as well as your own password to log-in to the page of the router, reset should be the next step. Reset only for 10 seconds and wait for power to stabilize. Admin should be working by then for password. By the way, if you need to reset the router in the process, everything will go back to defaults but I have links below that you can refer to on how to set it up for internet again.

Configure Airport via ethernet connection

Hi everyone,
Is there a way to connect to and adminster Airport Extreme base station using a physical (ethernet) connection? I could have sworn I've done this before but cannot seem to do it now and when I try, Airport Utility simply says it cannot find any base stations (its obviously only looking over wireless).
The reason I ask is that the router is apparently 802.11n capable however whenever I set it to use Wireless N my laptop cannot detect the network. My laptop uses a Broadcom 43225 802.11b/g/n wireless card.
Because I can't get the PC and Aiport to speak to each other over a phyical connection, the only way to get back on the network is to reset the router using the reset button, meaning I have to reconfigure the network every single time.
Anyway I'm blabbing on but if anyone has any theories as to why I cant detect a wireless N network I'm all ears, but my main question is can I connect physically to Airport Base Station?
Thanks.

You must use the older version of AirPort Utility on a PC to administer the AirPort Express devices, if you do not have a Mac using a 5.x version of AirPort Utility.
When you say that your ISP changed your sign in credentials, we assume that you mean to say that you have a new name and password for your wireless network. Would that be correct?
If yes, then you will need to reset each of the AirPort Express devices back to factory default settings and then set them up again to join the new wireless network there.
Power off the Express for a few minutes
Hold in the reset button on the Express first, and keep holding it in for another 10 seconds while you simultaneously plug the power back into the Express
Release the reset button after the hold period, and allow a full minute for the Express to restart to a slow, blinking amber light
The Express is now ready to be reconfigured again to join your "new" network.
Open AirPort Utility, click on the Express, and then click Continue to follow the guided setup.
Reset and configure the other Express devices the same way.

Gpib commands via ethernet

how can i control my device through ethernet by passing SCPI commands or GPIB commands.
The device is standalone industrial PC has laser sources.I need to control sources. The IP address is 202.10.10.2.

You can use VISA to control an instrument with an ethernet interface. Open a connection using a resource name of TCPIP::host address and then you should be able to send your SCPI commands with VISA Write just like you would with a GPIB connection. You should also verify that it's on the LAN from MAX. Right click on Devices and Interfaces, select Create New and then select TCP/IP Resource and then follow the directions.

Mac/Apple TV Connectivity via ethernet connection problems

I am having a connectivity issue with my Mac and Apple TV. I am connected to the internet via cable modem and ethernet lines. I have my Mac, Apple TV and cable modem all connected via a Netgear 5-port ethernet switch (10/100 Mbps). I am able to connect to the iTunes store (internet) with either my Mac or Apple TV by unplugging my cable modem and reconnecting with one device "on", but in order to switch from Mac to Apple TV (or vice versa) it is necessary to sleep the one device, and reconnect with the other. I am unable to communicate from the Apple TV to my Mac iTunes without a direct ethernet cable between them.
I suspect there's something in the system preferences that I'm not doing. All devices seem to work OK in isolation but not together.
Any ideas?

cuatro,
welcome to discussions.
Your issue is with the Netgear switch. It needs to be a router and also provide DHCP and NAT. It might be able to do this by re-configuring. In fact, as you describe it as a 5-port switch, it's very likely that one port is on the WAN side (internet) and the other four are LAN side (local). Which model switch is it ?
The issue start with the cable modem, which will only provide one Ethernet port and one IP address to access the internet. Your Netgear should really then put up a firewall and provide up to 4 local IP addresses (a LAN) for sharing access to the internet. It looks like it's not doing this, but just sharing the one IP address (supplied by your cable ISP) amongst all the attached devices. This can be a nightmare, as you are finding out.
Let us know about the Netgear and we can help.
Just in case the Netgear is unable to do what we want it to, does your G5 have more than one Ethernet port ? Is it physically possible to connect the cable modem directly to the G5 ? (are the cables long enough?) Is it physically possible then to connect the AppleTV to the G5 ? If not directly, then via the Netgear ?
It may be that you will have to spend about £30 on a router with firewall / DHCP / NAT / etc, or £40-£50 on a top-of-the-range wireless-n router, which your AppleTV will love. I'm almost certain that your existing Netgear is sufficient though.

Windows XP computers can't see Airport via Ethernet connection

I have a iMac G5 hooked up to a new Airport Extreme base station.
I have two other old Apples with which Airport Express Setup 4.0 doesn't work.
Therefore, I am trying to set up my two Airports using a Windows computer so that they can be used as remote music devices.
Neither of them are seen by the Windows computer unless I completely reset them. And even then, it is intermittent.
When starting Airport, I get the following message:
"Windows is not allowed to manage wireless networks on this computer." However, in Network Connections, properties of my wireless connection state Windows does manage them.
Following an Aiport reset, Airport Express Assistant asks me for the password for the network, "name not available," I enter "public," but then get the following error following the message, "Reading from Base Station..."
Cannot send Identify command to the base station. Bad Param Error (-4).
Attempting to access the Airport using Airport Admin Utility, I see the Airport, but when making modifications to the password and join an existing Airport network, I click UPDATE, the Airport restarts, only to be invisible again to both Airport Express Setup and Airport Admin Utility.
The same problem is happening on two different XP computers and with two different Airports.
Help!

Borrowed a Powerbook and used Airport Admin Utility, which resolved all problems with Airport.

Time Capsule to Extreme to Express via Ethernet Connection ?

Recently purchased all three to help simplify my Home/Business network but having issues connecting and communicating between all three.
Whole home is hard wired for ethernet in every room so I assume this would be the fastest method of linking all three together but would also like all three to broadcast wireless for full property coverage. I beleive I am using airport utility 5.6.1 for setup. I am working on Windows 7 machine.
Setup so far is:
Motorola Cable Modem with Charter Service to Wan Port of Time capsule (Seems to all work well)
Then in other room/level Airport Extreme with ethernet from time capsule to Wan Port of Extreme
and this is the point where I lose it... I haven't even gotten to the Express on the basement level..
Could anyone chime in with more understandable instruction on both hard wire configuration and software using
airport utility?
Or maybe point in right direction? What other info needed?
Certainly appreciate any help..

The roaming document explains adequately how to setup... at least the principle of it.
It isn't hard at all..
One device is the main router.. You create a wireless network from this router.
All other devices are bridged.. (that is router bridge not wireless bridge)
They all get IP address from the main router.
All of them create a wireless network..
if you want roaming you simply use the same name SSID (wireless name in apple speak).. same security setting WPA2 Personal = WPA2 AES and password.
But you can setup different networks if you want.
Channels are supposed to sort themselves out automagically.. but I don't believe in voodoo.. try voodoo first and if it fails, no biggie.. set manual wireless channels.. set simple short names no spaces pure alphanumeric.
It is perhaps new for you and the lack of html setup is a pain.. but it isn't hard to do. Apple have cut back the number of options to barest min to do the job.
Come back and ask specific questions if you run into trouble. We have some very clued up people here.. who spend their life energy answering the same question every day with a cheerful attitude.. never seen the like.. on a windows forum you would be told to RTFM.

Can I connect a NAS-based library and music files to an outboard DAC via ethernet

I am running iTunes via a Drobo Transporter NAS through an Airport Express using the analog output but would like to send the digital signal via ethernet to an outboard DAC. Is this possible? I haven't been able to get it to work. I am running a 2009 Macbook Pro 17", OS X 10.9.5, iTunes 11.4, Airport Extreme as router, ethernet connected to Airport Express. My network: internet from microwave tower to Airport Extreme via ethernet connection. Airport Extreme connected to 5-port switch which connects via ethernet to Transporter, outboard DAC, and Airport Express. My music files and iTunes library are on the Transporter.

Thanks, Niel! As it turned out, I had a LaCie rugged drive at my place which had both Firewire 400 and Firewire 800 connections and cables. So I hooked it up to the old iBook, pulled my sister's stuff onto it as instructed in the ppc to intel thread, and then hooked it up to the Macbook Pro. Problem solved! - almost. We did have two issues:
1. My sister has a lot of music - more than 12 gigs were on the iBook's hard drive, but only about 6 made it onto the Macbook Pro. Why is that? I also got a message, when I was trying to move the music folder from the old library onto the new one, that OS X needed this folder and it couldn't be modified. Again, why is that? How, then, do you move files from a PPC to a machine running Lion? Again, a lot of her music files did make it over, but not all of them.
2. All her photos did seem to come over - in duplicate, maybe even in triplicate. That is so annoying! The same thing happened to me when I was migrating between my old eMac G4 and my iMac G5. Why on earth does iPhoto do this, and how can we make it stop?!
But we did manage to get a lot of her stuff onto the new machine. When we get the adapter, she'll be able to add the files that are on the Verbatim drive. You've been very helpful!

Need to connect G3 (8.6) with a G5 (10.4.6) via ethernet

need to connect G3 (8.6) with a G5 (10.4.6) via ethernet.after upgrading G5 from 10.3 to 10.4 ,i lost server connection. to connect to server or browsing for server, G5 cant find G3. manually input of server ip adress of G3 doesn't do it either.apple talk is active and computers are via ethernet connected.anybody can help?!

I know that this one is already solved, but another solution is to just copy/install the AppleShare Client 3.8.8 to your older equipment that is having trouble connecting to 10.4 servers.

My Airport Extreme and iMac appear to have the same IP address as a result of installing a new ATT modem via direct ethernet connection. How can I reset the Airport IP without disturbing the iMac setting if the iMac can't reach the Airport?

My provider's (ATT) modem recently went bad and though I usually use an Airport Extreme connection to the modem I had to start up their new modem via a direct ethernet connection from my computer to the modem. In trying to restart my Airport to modem via ethernet connection I was told that my computer IP and Airport ID are the same and so now my computer will not connect to the Airport. How can I best get out of this situation?

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Airport admin can see Base Station, but only via direct ethernet connection

After resetting my snow (dual ethernet) base station, everything went well with the Airport Admin Utility reconfiguration. But after unplugging the ethernet cable between my computer and the base station, I'm not able to detect the base station wirelessly. Searching for "other" networks won't work. I've tried changing passwords, base station names, location names, network names, using the hex password. I hope I'm missing something obvious. Thanks in advance for any help!

Yes, the wireless network name (currently Apple Network xxxxxx), does not appear in the list. My iBook and Snow Leopard iMac cannot detect it, nor can two iPod Touches in the house. Nor can our Wii. All of which used to before all this. All these are able to detect other networks -- basically, all of my neighbors and then some that come and go.
I have not tried bringing the base station to another building. That’s a good idea.
I have tried http://support.apple.com/kb/TA20683 and kept getting stuck at the configuration stage -- where it seems to reset the ABS, but after which the ABS does not appear in the Admin Utility window. Finally, after many, many attempts at a hard reset, I’m almost positive the whole config & software upload took. My only evidence is that with the ABS still connected to my iBook (OS X 14.11 running Admin Utility 4.25) I can finally double click on “Base Station” and see lots of setting options, the correct Apple Airport ID, etc. In other words, as you guessed, I can see “(and, presumably, change) the wireless network name in the AirPort tab of AirPort Admin Utility (the default is something like "Apple Network xxxxxx") when connected via Ethernet.”
What led to this? It all started when I was trying to get our Wii on to our wireless network. But the Wii wouldn’t log on. It gets foggy after that (I’ve tried so many things, I’ve lost track of the initial steps creating the problem). I might have tried changing channels or something from my Snow Leopard computer, having forgotten that my Snow Leopard computer can’t administer my dual ethernet ABS. It’s possible it really started with turning on and off my DSL modem, which forced me to reset my DSL password with ATT.
Come to think of it, that might have been how this all started. After turning my DSL modem on again, ATT wanted me to download special software for me to reset my password. That wasn’t working (whatever it was would never load. But, I found a way to do it online. Otherwise, my browser kept spitting me back to ATTs password creation page.) By the time I went to my iBook to get into my ABS, remembering that was how I needed to tinker with it, to get back to the original Wii issue, I had lost all connections to my ABS.
Until now, where I can at least see the ABS again in the Airport Admin Utility -- via ethernet connection only.
