content: HiI am trying to connect Fluke 8846A digital multimeter to the computer using the ethernet port.I have tried whatever that was given in the programmers manual about the LAN connectivity, but to no success. I know I am doing something wrong, but I am unable to figure out what. It could be kind enough of those here who have had experience with this device to help me.Thank you.

content: Are you using a hub, a direct connection or what? If you have a hub is the link light coming on when you plug in the cable?

content: Hi,i got 8846A.. and may be at help, but.--if you told us exactly what you are doing, step by step, and whats result that give step by step, its easier for us to find out whats happening and what you do wrong.

content: With no details it is impossible to tell, but 90% chance the problem is either:1) you have connected the fluke directly to a dedicated ethernet port on your computer but have DHCP enabled. Manually configure the IP and subnet on both the host PC interface and the fluke.2) You have connected the fluke to an existing LAN but have a static IP configured that isn't part of your local subnet. Turn on DHCP so that it can get a legal address from your subnet.There are any number of other problems you could be having: You aren't connecting correctly, you aren't sending legal commands, your EOL string is wrong (I don't remember how picky the 8846 is on this), or you have a misconfigured firewall, or you have it set up to listen on on of the other interface ports.

content: @ericone more source of probem is the type of cable he might be using.straight-through or cross crimp.if i remember right he ll need a cross crimp for a direct to PC connection and straight through for a hub.@tenalias all the above mentioned. you have not given any data to help us help you.Be a little more specific.what is given - what you tried - what you expect - what happened/did not happen.in that sequence.

content: Hubs have long been replaced by switches. Almost all (gigabit) NICs in PCs support auto-MDIX these days. My initial guess would also be that it's IP addressing related, but without sufficient information there is really no way to tell.

content: A ping to the meter should show and tell a lot about the problem (give that you set a IP adress first, that is free- not used by any other on your nettwork), plus be sure that the meter is set to IP communication..

content: Sorry to reply so late.Right now, I do not posses the multimeter (8846A).I am not well versed with the know-how of how to connect any instrument with a computer.What I did was as follows:I directly connected a lan cable from the PC's lan port to the fluke meter's lan port.I went to the PORT IF settings of the meter and changed the IP settings etc., as shown in the manual.Then I tried to communicate with the meter from the PC using telnet.The connection failed.Currently I am not in possession of the device. I will try whatever you guys tell me as soon as I get my hands on the device again.

Its when I couldn't get it working even after following the instructions in it, that I asked my question here.I will try to get a switch.I did start off with the programmer's manual. Its when I couldn't get it working even after following the instructions in it, that I asked my question here.I will try to get a switch.Edit: I couldn't get a switch. What I got was a crossover ethernet cable.Then I followed the instructions given here:http://assets.fluke.com/software/bench/readme.pdfStill no luck.There was slight confusion while following those instructions.After "ipconfig", I get this:Code:Windows IP ConfigurationWireless LAN adapter Wireless Network Connection 3:Connection-specific DNS Suffix . :Link-local IPv6 Address . . . . . : fe80::dcf6:3285:a7f4:5d32%17Autoconfiguration IPv4 Address. . : 169.254.93.50Subnet Mask . . . . . . . . . . . : 255.255.0.0Default Gateway . . . . . . . . . :followed by:Code:Ethernet adapter VirtualBox Host-Only Network:Connection-specific DNS Suffix . :Link-local IPv6 Address . . . . . : fe80::31d6:1c60:4cee:b3e8%26IPv4 Address. . . . . . . . . . . : 192.168.56.1Subnet Mask . . . . . . . . . . . : 255.255.255.0Default Gateway . . . . . . . . . :with multiple lines of "Media Disconnected" in between and around.Now the manual states to select an IP, and change its last three digits, while entering it in the 8846A.The programmer's manual cautions about the following:When addressing some LAN addresses, computers will often interpret 0's inthe IP address as OCTAL values. As anexample, if you configure your IPaddress from the front panel as 129.196.017.023 and then attempt toestablish a connection to the meter, you should connect using the IPaddress 129.196.17.23. Attempting to establish a connection to129.196.017.023 may result in a connection request to 129.196.15.19.I am wondering if I am doing this mistake.Thanks for tolerating me.

content: Quote from: TenaliRaman on September 30, 2012, 07:02:27 amImpressive .....So you can connect to a Fluke without a cable ?I'd say you might if you configured the fluke for dhcp , and connected the fluke to your wireless router. And configured your PC's wireless for dhcp , and connected that one to your wireless router./Bingo

content: Regarding cross or patch cable (strait) - it is also depending of port configuration. Most of current computers and switches has automatic detection. Network card detects which cable is used and reconfigures themselves. Most problematic is DHCP and correct address settings. For checking communication and basic operation you can try this software:http://www.elso.sk/softver-a-prepojenia/1873-elso-lan-measure.html
