After 3 times "Any help on this please !" and now "up", it´s may be time to change strategy.

Plan A: Use your brain, it´s a wonderful machine.
Plan B: Don't give up with Plan A.
Plan C: Don't give up with Plan B.

.....

Plan X: Open the device, do some measurements, post here pictures and results. The more you post the better it is. Do you have a scope and a DMM?
Plan Y: Contact Fluke for the service manual or information regarding those errors.
Plan Z: Buy a working unit, fixing the broken one by taking the good one as reference. After fixing the sutff sell the one you don't like as working device.

Hi,

I also have a DSP-2000 with the 232 error. Did anyone make any progress on this?

I have a few units, so will do some part swapping, but any pointers in the right direction would make it easier for me to get back to this post with better information for anyone else with this problem...

dinix · « **Reply #9 on:** December 11, 2019, 10:05:16 am »

pete1zed: i found this issue is related to a small hover board mounted near the monitor rj45 port.

one of my dsp2000 had that issue and was only a bad contact on the connection of the board. i disconnected, cleaned and connected and got fixed.
when that board is disconnected if you turn it on the error appears also.

Right now i'm trying to figure out other issues in my other units:
-the error: "overvoltage on input, disconnect cable" even with cables disconnected.
-No power up, waiting for an internal battery to try if it resolves.
-Some dsp4x00 units not booting, only shows the screen flashing, waiting to replace the internal battery also

pete1zed · « **Reply #10 on:** December 14, 2019, 03:55:17 am »

Wow, just like you said: I bent the connector housing on the floating board back to being straight, and the error went away.
Thanks so much.

I also ordered a USD$30 LCD screen from Aliexpress to replace the one it has, which was suffering from a few dead rows.

Total spend so far for a perfectly working DSP-2000 = $0.99 for the "not working" DSP-2000 on Ebay, + shipping, + $30 LCD screen

I upgraded the firmware to the latest version too.

With the cover removed, if you turn the rotary switch to a position only available with the cover removed, it becomes a Smart Remote.
The Smart Remote status is displayed on the LCD instead of Smart remote LEDs.

I have replaced some of the CR2450 batteries, but just soldering onto cheap $6 Energizer batteries from the hardware store means they heat up a lot during the process -- that may make them leak over time perhaps. I am going to experiment with soldering using a low temperature solder (Chipqick SMD1 kit from element14 melting point 85 deg C but is actually an SMD removal product, so failing that: Chipqick SMDIN100 which an actual solder, Indium with melting point 143C). That is more economical than buying lots of tabbed coin cells.

If you need any spare parts or help let me know. I have posted all I know here.

I would really love a copy of the service manual if any has one...

dinix · « **Reply #11 on:** December 14, 2019, 05:04:59 pm »

pete1zed: thank you, very good and organized data.
I'll see if a can find something to add.

The service manual seems to be unobtainium, maybe someone can help were

pete1zed · « **Reply #12 on:** May 08, 2020, 10:31:29 pm »

I have updated my servicing notes and other resources for the DSP2000 here, and there is also some firmware for that and the DSP4xxx models there too.

What is the failure of the equipment?

Hello, did the change of the internal battery solve the problem with the booting and the flickering display? Greetz

dinix · « **Reply #17 on:** February 03, 2021, 09:06:50 am »

no it didn't solve

mk247 · « **Reply #18 on:** April 09, 2021, 09:16:37 am »

Hello, has anybody a working firmware for the fluke dsp 4300 v.1925. Thanks

zeb · « **Reply #19 on:** June 14, 2021, 03:30:50 pm »

Hi. Sadly finding Fluke firmware for end of life equipment is very difficult but I do happen to have 1.925 for the 4300. Just let me know how you'd like to exchange the file. Somewhere I also have the latest standards file that includes patch leads (I happen to have the patch lead modules for mine).

@yppu: I also have a 4100 that failed its calibration. Unfortunately I don't have any way to read the flash chip. :-(

Zeb.

Looking for any suggestions as to why, after years of sterling service my Fluke DSP-4000 main unit suddenly just displays some horizontal bands when powered on...it was pworking perfectly when turned off the day before!

echomz99 · « **Reply #21 on:** June 22, 2022, 07:34:30 pm »

Hallo,
is there anybody with a working firmware file for DSP 4300 (1.925). There is no more support from FLUKE because EOL.

Thanks

Alex

Hi,
You need it?

Tomcoli · « **Reply #23 on:** August 09, 2022, 02:35:55 pm »

Hi Asia

Would you have the patch cord standards for a dsp-6s? Thanks

VincentK · « **Reply #24 on:** September 01, 2022, 03:39:07 pm »

Hi David, did you managed to fix it? Was there LCD screen? Or was something else. Mine started behaving same way last week.

I have multiple 4100 units like this, i have checked the whole board and seems nothing wrong. I pulled both U17 & U18 AT29LV040A off the board and read in programmer but both modules are dead, i have new ones but unsure of how the flash should be done, the remote unit firmware is less than 4mbit so i have flashed onto both chips and replaced but remote unit still not booting.

The address lines of the 4mbit eeproms goto the MC68307V so it's likely i guess that the firmware is motorola assembly.

I have a DSP-4300 not booting, The U17 is damaged. Can anyone read the this chip?

Ned70 · « **Reply #27 on:** January 25, 2024, 10:07:26 am »

Hi Asis,
I’ve just been searching through form posts looking for firmware and standards files for my DSP-4300. I know considerable time has passed, but do you still have 1.925 and do you have the Standard 5.17 file? I look forward to hearing from you.

asis · « **Reply #28 on:** January 25, 2024, 12:23:40 pm »

Hi,

I'm already retired and don't work with these TDRs, but there are some files in the archives on the old PC.
Tell me what you need and give me a link to a file hosting service to which I will try to upload.

The1 · « **Reply #29 on:** January 25, 2024, 12:53:28 pm »

Thanks for taking the time to post, we already have those files, what we need is a read of the internal eeproms from a working unit. To restore the bootloader.

Swap007 · « **Reply #30 on:** April 03, 2024, 07:16:06 am »

It is someone who can give me a firmware or database with some instructions for DSP-4300? I bought another remote for the main, but he arrived with 5.17 standards and older firmware, I found the firmware but database standards it remain at 5.17 and I must have 5.19c.
Or is good to downgrade the standard on main unit from 5.19c to 5.17? With another firmware write to main unit?

asis · « **Reply #31 on:** April 03, 2024, 09:52:16 am »

.. see PM

Hi,

same problem here. 4100 and flickerig screen on bootup. seems like U17 & U18. Does anybode have files in the meantime and managed to program them?

AmishThunder · « **Reply #33 on:** April 11, 2024, 05:09:41 pm »

Just signed up for EEVBlog Forum so I could say THANK YOU for posting that all over on your Google Drive, pete1zed!

I have a few DSP-100s that had mis-matched firmwares, and so they wouldn't work together. Although you don't have the -100 FW posted, you pointed me in the right direction with the wayback links.

Now some extra info for those struggling with LinkWare 6.2, and the info is probably useful to those that have a DSP-2000:

-Yes, LinkWare 6.2 installs and runs fine on Windows 11.
-Yes, Using a USB to Serial adaptor works fine (as long as it's in a null modem configuration, and correct drivers are installed on Win11).

For my first attempt at upgrading the firmware of the DSP-100, it appeared to be successful, but the DSP-100 wouldn't start up. It just made one beep, then the screen stayed blank. I thought I'd bricked it, but luckily Fluke made it so that even in that state I could just initiate another firmware update from LinkWare. The unit being upgraded must be in the Auto Test position, and even though the screen is blank, it's actually on and ready to accept firmware.

After firmware updates, you will need to do a self-calibration, and that WILL require either another DSP (with display) or a Smart Remote (no display)...Both the DSP and SR must have the same firmware. FYI, the update process for the remote is the same as the DSP: Turn on, connect serial, initiate an update, but instead choose the file beginning with "SR".

Hope the above helps someone, and thanks again pete1zed for your posts and files. I've had this DSP-100 since 1999, and although it isn't useful for qualifying any modern ethernet standard, it still is useful in many other ways. Glad it's a part of my kit!

CM · « **Reply #34 on:** April 21, 2024, 10:52:10 pm »

The internal battery on my DSP-4100 is dead. Does anyone know the part number for a "drop-in" (solder in) replacement, or where I can get a CR2450 with the same pin configuration?
