content: 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.

content: 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...

content: 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

content: 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 screenI 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.https://drive.google.com/open?id=1yVDiAwMg3zo4jIwa44o64lHkammTZvIUI would really love a copy of the service manual if any has one...

content: 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.

content: Quote from: davidwf on January 14, 2022, 05:48:26 pmI 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.

content: 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?

content: 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!

content: I have two broken Fluke DSP4300SR remote units. Unfortunately, I don't know their earlier history. I opened the devices, but can't find any damaged components on the PCB. I replaced the internal CR2450 battery because it was dead, I uploaded the latest firmware via LinkWare (the same version as in the main unit), I gave new NiMh batteries (Cameron Sino), but they still don't work. When turned on, all LEDs light up. LinkWare shows internal error 208:Boot 1.925 11/06/06 16:01:03 000000 008000Cal 1.921 11/29/04 16:01:05 008800 01b200Sdb 5.17 11/06/06 16:01:04 024800 00be00MainSR1.925 11/06/06 16:01:08 030800 043f00 **** FAIL ****serial num=0XXXXXXXhw lev=10cal date=010610Analog rev=100Digit rev=100Keybd rev=100Internal Errors:208 02/11/00 09:15:19I'm starting to suspect that the AT29LV040A-20TC microcontroller or Samsung K6X4008T1F-GF70 RAM may be damaged. The parts are no longer produced, but they can still be obtained, but the problem would be to get a memory dump from working unit.Has anyone encountered such an error, or has access to a service manual to check what this error means?

content: Hi,I recently got a DSP-4000 from my school for free, because it was broken and they were moving into a new building. It has the same issue described erlier wit the rolling bars on the screen and is not beeing recognized by the LinkWare software. The remote unit actually behaves the same as the main unit in my case, with it not turning on and it not beeing recognized by the PC.How hard would it be, to flash new roms for both units with the rom images, and what specific chips do you need for the two units? Is it even worth it to repair the analyzer, or would it be smarter to just sell the analyzer and the accesories as is?

content: I've looked around for more information regarding this fault.A repair center confirmed that the issue for the "flickering screen" is likely caused by the dead EEPROM.The same repair center would charge more that 1000$ to "reload the firmware with the serial port".On this board there are 2 undocumented "ports" that could resemble JTAG ports / Debug Headers.I've already replaced the dead ROMs with MX29LV040CTI-70G ( identicall to ATMEL Originals)How would you tackle the firmware restore for this unit?
