content: Hi all,I was wondering if anyone has any experience with one of these rack mounted keysight scopes. They're very hard to use without a network connection and I've been trying for ages to get one here to talk. I've tried standard ethernet cables, changeover cables and got nothing. I've tried using the autoIP system as well as connecting to a DHCP server on a router which doesn't even register it as a connected device. I've reset the LAN configuration back to default. There isn't any way to control locally as the USBs can't take any actual inputs.Any help would be greatly appreciated

(and lan cable connected to working router)

content: Quote from: egonotto on May 23, 2025, 02:34:31 amI think he may have a problem that after reset some of scopes need a change of setting to actually activate the remote access from another computer but if his is not reacting to USB mice it can really be a problem.

content: Hello,does the LAN lamp light up green?These devices have no controls other than a brightness control. And there is no mouse.The device tries to establish a LAN connection automatically after switching on.Initially, the LAN lamp is red. When the LAN connection is established, the LAN lamp is green. This can take some time.If I remember correctly, I had difficulties at the beginning with an old DSL Fritzbox. But that was the Fritzbox's fault.Best regardsegonotto

content: true they do have some problem with certain routers and switches but any more common used ones should work - Fritz is kinda specific and tricky hardware sometimes hehe (but usually good, not bad words on it)

content: he may need to use the so called crossed cable not usual straight one patch cable cause this scope is not auto MDI-X capable (reminder of old times when lot of things needed that)

content: I have a monitor connected through VGA, however it just shows the standard oscilloscope interface. The ethernet connection is indeed non auto-MDIX so I have got both a crossover cable I made and a standard cable for testing. I am not 100% sure what version of the ethernet wiring it wants explicitly. The USB interface is purely for storage and does not provide a mouse/keyboard interface.The LAN LED turns green after startup. I have connected it to a router with a DHCP server on it, however when checking the router, it doesn't register it as a device with an IP address from the router's interface.I have got a usb connection to the scope however this does not provide a GUI for controlling it.It is this oscilloscope:https://www.keysight.com/gb/en/product/DSO6104L/low-profile-oscilloscope-1ghz-4-analog-channels.html

content: I've tried using the hostname but that never manages to connect to anything. It seems to not be getting to the point where the computer can even recognise it.

content: Quote from: scarysparks on May 23, 2025, 10:43:12 amdid you connected trying it via router or straight to PC/via switch?In case you are using a router depending on its settings you can have those adresses not routed at allIn case of direct connection/via switch you need to set up your IP/subnet on your PC accordingly manually to be in "same network" as scope isThere is also the wireshark that you can run on PC to scan network traffic to pinpoint scopes traffic when it boots up and tries to handshake with router to get its IP.If everything fails you may sadly need to call Keysight for help and perhaps the scope may need a repair :/

content: Same s*it every time. Engineers which plays with LAN in some corpo for decades, but they can't spend 15 minutes to learn basics about TCP and IP(v4) protocols. Also Ethernet uses MAC addresses for devices to know who is who.IP is like note glued to MAC (basically a simple table). Also You have mask, which can make many networks in one physical network. For example, my scope which Im using right now has manual address 10.1.1.12 (long story why those exact numbers). I set a mask 255.255.255.0 on both sides, which means I can change last octet (last number after last dot) to whatever I want and I will be still able to communicate (unless there is some another barier like a computer with iptables rules or I have same IP). If I change mask to the 255.255.0.0, then I can change two last octets.https://en.wikipedia.org/wiki/SubnetIn simplified words, You have three layers:1. Physical which uses MAC as a addresses to communicate.2. IP layer, which translates IP to MAC.3. TCP, UDP, ICMP and sometimes other protocols. First two uses port numbers, but those are separate things. I can have web server working at TCP 80 and in same time some other thing at UDP 80. ICMP is used mostly to diagnose connections, like ICMP ECHO_REQUEST and ICMP ECHO_RESPONSE - those two are most known as ping.So You have to check everything in same order:1. Is there physical link registered in the system? I know how to check it on Linux, but on Windows, even if I knew, I wouldn't tell. There is a lot of idiots making CAT 7A keystones than can't handle 1 MHz of sine wave - because corpos like to make things cheap. Nobody asks stupid questions if that will work and for how long.2. Is IP address inside ofprivate networklist? If You have private network, in most cases You should use only those. Check mask and associated firewall rules if there is any. Eventually check routing table on both systems.3a. Use ICMP to diagnose any sign of life.3b.Check opened portson both sides. Eventually You can use tools to check it remotely, but those are often used to do bad things (especially on Windows and cheap xero machines), so sometimes other side can block You forever and ever (mostly something between 1h and 7d, since storing ip address of idiots can take huge gigabytes).Simple?

content: Quote from: kmoonwalker on May 23, 2025, 07:27:41 pmIf somebody is doing things with a method trials and errors, and he gave that "huge" amount of Information of this problem, we are just unable to help. If somebody world is candy-looking Windows, and he thinks that all he needs to know is IP address, most likely he will not consider learning anything. Just try and try and try until it will work. 5 minute job done in one moth, because he don't even know how to ask.Many years ago I was working as a technical help (call center) with ADSL based internet connection. More stupid and more unpleasant somebody was, I was trying harder to prove that fact to him/her, instead of helping. After 12 months I gave up - at the beginning I was spending more time on playing games at work than talking with clients. At the end it was the opposite and not only this.

content: we shall see - it maybe that he never used such scope or equipment before and purchased it on some offer and now trying to get it to workor maybe that scope is really brokenwe certainly need more info

content: I managed to get it to work.As stated, it is non auto mdix so i had to take a lan cable i had and repin it into a changeover cable, there's a few different arrangements that can be found on the Internet but I found that the standard one worked where1 -> 32 -> 63 -> 14 -> 75 -> 86 -> 27 -> 48 -> 5Checking wireshark, i could see that it was requesting ip address 192.168.0.21 and then creating a redirect with the hostname. I then set my ethernet port to 192.168.0.22 and using the hostname in the browser, i got the interface.Trying to get the remote control system to work required java which edge doesn't really support anymore. I installed Java and enabled Internet Explorer compatibility mode for that address, allowing java to run. This then threw up a java socket permissions error which was fixed by finding the java.policy file and editing with admin permissions. I added in " permission java.net.SocketPermission "192.168.0.21:5900" "connect, resolve"; ". After restarting the browser this then let me access the scope. These scopes have a10MHz reference input that can be enabled. If this is enabled and not connected, it will complain about it and the web ui does not register the ok button as an input so i found that you have to provide the 10MHz signal and can then turn this off in the options later.Thanks for the suggestion of wireshark, seeing it working on the low layer really was whatwas required to get this finally working
