I'm trying to do the firmware update on a Fluke 8846A using the SW from Fluke.  I connect to ethernet, assign an IP address to the DMM, and connect to the same router as the PC.  I load the SW and try to connect to the DMM with the SW but it doesn't work.  I even did a PING and can talk see the DMM on the network.  So my IP is correct.  I do a telnet command to the IP address with the prescribed 3490 port #, and it says it can't connect.  I do a telnet to the IP address with no port #, and it connects, shows me the host name of the fluke meter and asks for a login.  I don't know what to put in the login.  I tried typing a variety of things including the factory default password "FLUKE884X" then it asks for a password.  But I can't type any passwords (or at least no echo to terminal).

So I see that I am connecting on the internet, but it seems like there may be a problem with the port number.  Maybe security in my internet at work is blocking port #'s or something.  I tried a variety of subnet mask values and default gateway values, but no luck.  I turn the DMM off and try a PING, and it times out (nothing there).  And with DMM on, I get 0% lost (100% make it through) on the PING.  So I am pretty definitely connecting.  Some more complex internet protocols are just a little over my head.

Any help appreciated.

Always best to use a stand alone computer with no anti-virus software or firewall and a crossover cable for your connection.

While on Kwaj. Had to build a special computer without all the Government/Army firewalls on it to do upgrades. It was never allowed to connect to the network.

We've been going through a similar problem with a Tegam 1830A Power Meter.  We also use a non-network computer for the calibration.  The manufacturer recommended a default gateway on the computer of 0.0.0.0 when doing the 1830A, maybe that would help in your case, hope so.

Thanks both of you for the inputs.  Does anyone know which pins to cross over to make a null LAN cable.  Am I correct that it is kind of like making a null modem serial cable, only with a CAT5 cable?  We have a bunch of CAT5 cables around.  I could just strip back insulation and swap TX and RX wires if that is the case.  I'll try looking it up on Al Gore's interweb when I get to work to see what the pinouts are, and make one.

Speaking of Tegams, I also have a Tegam system - one of my other projects coming up.  Maybe more on that later.

What firmware update? I have a large number of 8845's and 8846's in my cue. I did not see anything about an update on the website.   :? :|

My 8846A is older, and has very old firmware. There is definitely firmware updates which I had to search around to locate.  They were not to be found on the U.S. site.  I found them on the .EU Fluke website.  It is their firmware update package.  I'm not sure why its not on the U.S. site.

I have been told that the 8845A/46A firmware CANNOT be updated by the user; it must be returned to Fluke. I was also told that the availability of the firmware on the EU site was in error. Perhaps a quick call to Fluke can confirm or deny.

the fluke site states it is user downloadable.
"Everett, Wash. - Fluke Corporation has announced a user-downloadable firmware upgrade for the Fluke 8845A/8846A Precision Digital Multimeters that delivers even more functionality and value from these powerful instruments."

I have spoken with Fluke. It seems that it USED TO BE available for user upgrade on their website, but was pulled due to a few customers being unable to 'wake up' the instrument following the upgrade process. If the firmware is still on the site, it is a mistake (maybe that's why Hawaii596 only found it on the EU site), I was told.
