content: I've got a ET5410Quite a nice feature set & performance. - good value for its power/performance.USB connection works, I have a 115200kbps terminal connection, but no info about communication.I have tried to get the command set and/or software from "East Tester" - but they do not respond to mail.I hope somebody here has some software from them? or knowhow about the command set.

content: I've got a copy of the ET5410 software command list from East Tester. Unfortunately, I am unable to upload it as it is in docx format. I also don't trust the manufacture so I am a little concerned with Enabling Editing and saving as PDF on my PC. If you need the doc still, I am happy to email it to you.I've attached a snippet from the manual.

content: Thanks for the command list, i've been looking for this!As a side question, has anyone figured out how to adjust the slew rate in the dynamic modes? The east tester website lists "Up/Down Rate" as configurable from 0.000~1.5 A/uS (http://www.easttester.com/a/Product_introduction/ET54_series_single_double_c/2018/0611/118.html) but i don't see any mention of how to set it in the manual nor inr the UI (nor in the software command list, which was the last place i could think of to look for it). I love the ET5420 in every other way, its's small, cheap, accurate, nice screen, 2 seperate channels makes it super flexible, USB control, etc. But the lack of configurable slew rate is something i realy miss testing and tuning SMPSs way harder. (FYI it seems like the default slew rate is very slow, ~1A/6.8ms in Trans mode from 1A~3A measured at 10%~90%. Or ~0.000147A/uS which is the very minimum of the control range in the link above)

content: I have the ET5420 but cannot communicate with it. The USB is connected and reports as COM5 and I am using Putty to connect to it at 115200. I can enter *IDN? all I like and there is no indication of error but there is also no response from the ET5420. All of my other devices work and respond perfectly (Korad, Agilent,Tek) Is there some secret information about it perhaps that East Tester is afraid to divulge. The manual is useless and there is no response from the mfr so I seem to have wasted my money. I have tried the so-called local/remote setting using Shift->Local but it seems to have no effect whatsoever. It doesn't change an icon anywhere or anything.I would much appreciate anyone who could help.

content: Quote from: gbatson on September 18, 2020, 06:25:07 pmEast Tester do not really follow the standard. Try using "*IDN?", i.e. using upper case letters.I had a lot of issues getting the ET3240 working, one was the case of the letters, another was the end of line.In my test the documentation was correct, but rather limited, i.e. the commands worked, but you had to issue them exactly the correct way.If you get it working, please consider doing a implementation for TestControllerhttps://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/The idea with TestController is to support a wide warity of both cheap and expensive equipment, i.e. making it possible to mix high performance/quality equipment with cheap equipment in a (automated) test.

content: Bit late to this thread (only had one a week), but after some faffing about, managed to get the ET54 to communicate with Windows PC (USB serial) using the DC Load SW app available from East Tester. Needs a CH340 driver, the NI-VISA download and (probably) the NI-Labview Runtime Engine. The NI-VISA was the final break through, which was installed after the Runtime Engine, so Runtime Engine may not be required. More details can be made available if anyone stumbles on this thread...

If yes please send it.sorry ,we have not new program about ET5410I repliedI am not satisfied with the instrument and probably will replace it with another brand.I am not satisfied with the rigidity of your answers, generally, those who produce instruments, accept the improvements proposed by users,example implement <*RST> command for reset instrument.furthermore I'll look for some colleague near me who has an ET5410 to try with my system and software.

content: Interesting SPAZIONICA..keep sharing your progress.Recently took the plunge on a ET5410..I reckon they were clearing stock at Banggoods EU warehouse as I haven't seem them cheaper here in Europe (144US delivered, & incl. 25% danish VAT) nothing came close on features & bang for the buck here regionally.My unit seems to have been produced at 1Q 2022 according to the incl. QC label, - it seems to fit as some of the inner parts are labelled at 4Q 2021Picture slide with also some videos' of the inner components & board revisions, (hardware model v1.03.21.36.003 / software 1.02.21.27.002) and also some tests up around 420watt and 40A load with LIPO's...quite impressed with the programmable features its packinghttps://imgur.com/a/WKpaEOsHave also tested some of my older 18650s and the old so-called Sony VC4 holds up very well and is one of the better above 20A.still missing to try out the ET54-series software, its seems its NI VISA mandatory - and you literally need that massive size-chunk..Will also try-out lygteinfo's Testcontroller. (HKJ)Overall, at first glance Im quite impressed with this unit (obviously with the price in mind) its simply stuffed with programmable features.. that ain't the norm in this low-end price ballpark.It's obviously a noise fellow when dumping a huge load into it.. it's around +100w or 200w it goes into jet mode, but that fanblasting goes without saying for a sinkload that your dumping this kind of heat into.

Of course, it showed anything but correct readings! Mine displays 31.42V with a 30V input and no load.They won't tell me how to calibrate it and thought that I should spend my own money shipping a heavy electronic load from Sweden to China to have it fixed! Great support for a brand new unit - send it back to us at your own expense! We don't care if the shipping is more than you paid for the device in the first place!

content: Quote from: DaneLaw on July 06, 2022, 06:20:36 pmHi Danelaw, Have you since been able to use East Tester's "LOAD" software? I have it sorta working. But I've just naively installed it, hacked around with COM settings and can now send and receive from the ET. I've not installed anything additional, e.g. any National Instruments utililties (nor would I know how to). I'm guessing their software is some canned executable generated by LabWindows(but have almost no familiarity with LabWindows).i'm stumped at the point of getting the numerical data received from ET5410 to plot (i.e. Volts vs. Amp-hours) on their canned chart, aka "Figure", have you had any success?

content: Quote from: Curious on July 28, 2022, 07:36:32 pmI tried it yesterday.on one of the laptops, I recall I still have NI Visa on.It's a Win11 pro, but I'm pretty sure I'm doing something wrong, or it's not working fully..as the only thing I'm able to be more or less initialize it, and then I can turn on the load and turn off the load with the PC sw. by clicking down at the left bottom corner (with these 3 bars.. PC, Remote, CH1 on/off.) and jump between the different modes.I don't seem to be able to put any values onto the device..if I hit that numerical numbers and hit enter or turn that dial.. it simply does not resonate with the device, even though they clearly are connected but could be something as simple as a setting I'm lacking.I plugged in a USB3 cable. and choose the same 115200 baud as I recall were present from scratch on the unit.Could be something fundamental / obvious, I am missing as a novice - or perhaps it's down to win11pro or I need to run it in some combability-mode or maybe there is a basic feature I haven't activated on the unit-.In this state it seems broken at my end, and not useable in this state if you cant put values onto the unit, but it's very likely that I'm doing something wrong.but if you're able to send values to it, and the device adjusts to it on the display, then your way ahead of me..It seems it gives an error "000execution error, possible cause: load is on". (which it ain't if it's referring to the red active load-dot)It works fine choosing the different mode-settings, and the ET5410 display adjusts accordingly, but actually dialing in a given value by the 1-9 number + enter or using the big dial in the center' or some of the shortcuts ... it won't adjust to these values... I have tried to run the program in win7 combability and with admin rights.(it made no difference).Took a brief look on Youtube to see if anybody demonstrating this ET54 "LOAD" software and its abilities, in the hope I could get an idea of how it should run, but nothing pops up..https://i.imgur.com/792VdVF.mp4// some screenshots of advance/extensive battery testing feature (with around 250 log-levels), though' seems to be only valid, if you choose 485-seriel in the connection settings (x' in the above 485 connection screenshot pic4)...though not relevant for me, as I'm only connected with USB, and then these top banner-options don't figure' when you initialize with USB-com.- screenshot examples, if others perhaps would find it useful

content: Quote from: HKJ on July 29, 2022, 07:15:54 amHello, wow, that looks like a very powerful and widely applicable program! Big picture question at the moment though, how many hours/days do you think it will take for someone who just looked at the program and documentation today to get a reasonable Battery discharge curve (prefer Volts vs. Amp-hours)? I have only rudimentary programming skills, learning the scripting language seems daunting. I have an immediate need, have purchased a LiFeP04 battery that claims to be 36Amp-hours, but first battery test with ET540 at 0.1C shows ~30AH, needing to quickly get those results better documented to convince seller to replace or refund.

content: Quote from: DaneLaw on July 29, 2022, 12:51:25 amI just installed the LOAD.rar, which installed a bunch of scary NI-VISA stuff. No NI stuff on my Windows10 PC before this. I'm able to immediately update ET5410 current setting by either the (eccentric) knob or the 10 digit entry. Setting updates after "enter" with 10digit and immediately with knob. I havent found any effect of the lower left switches Local/Remote/PC, except that some combos don't allow usage of ET5410 controls.FYI, link to Video of ET5410 and PC screens while changing current settings in CC mode...(hopefully link works, how are you embedding mp4 files in your post?)https://drive.google.com/file/d/1--QffWxmANQ0icvfqkUkX05nT-Jefmet/view?usp=sharingSo at this point for me with vendor's "LOAD" software: 1. control of ET5410 from PC is working, 2. rudimentary feedback from ET5410 so LOAD software showing Volts and Amps on the main window, 3. NOTHING working on the "Figure" window, which includes datalogging, exporting, plotting.

content: Quote from: Curious on July 30, 2022, 05:48:20 pmIt do not require any training or anything else to use TestController for discharging a battery (Use Popup Log Event), but controlling it from a script and formatting a chart with annotations do require some smarts. Note: TestController can generate scripts for a lot of stuff, but the example I showed requires some understanding of programming to setup TestController to do it automatically.You can do a lot of stuff from the popups, but if you want to do it automatically it requires a script. This is only relevant if your want to do the same test multiple times on different devices (Here batteries).

content: I have a ET5420 with a USB interface on the back - and so far trying to communicate to it has been a failure. I have 2 types of USB to DB9 converters - both work on my linux PC using a terminal program and shorting TX/RX together. One of these converters apprently does not work on the 5420 - I have no voltage on TXD - the other converter I do - so I'm using that one to connect to the 5420. I'm using a DB9 to DB9 "null modem" - since I'm connecting a DTE to a DTE - and also a gender changer. So far zippo. I tried using East Tester software (using a Window VM in Virtualbox running on a host linux system) - the java based Test controller via linux - an async terminal program (linux) - I can't seem to get an response from the 5420. As I mentioned one USB to DB9 converter definately did not work - the other one seemed to work (at least I had an RS232 signal on TXD when I connected). Does anyone have a USB to DB9 vendor specific dongle that they have successfully used? Or any other suggestions?Thanks...EDIT: I think there may be some issue with the VCC/Grn power on the USB interface. From pin 1 and 4 Ion the USB interface should see (from what I read) 5VDC - I see 2.6VDC. I traced the connections back to the PCB mounted on the front - and it also shows 2.6VDC on the connectors. At this point in time unless someone has any suggestions I'm stuck. What would be really nice if they still had a RS232 interface on the board somewhere - there is a DB9 cutout on the back of the case that would be easy to wire up. Anyway comments/ suggestions would be appreciate - otherwise I'll mark this science project incomplete but done :-)2nd Edit: OK....so there is a RS232 interface chip on the front PCB board...I connected TXD/RXD/Grd from that chip to a DB9 interface - and I can at least (partially) able to communicate to the 5420. On the Test Controller software this is the message I get:Physical Port S0 (ttyS0) Device ET5420 do not match: ÿÿÿÿÿÿÿ,V1.02.2127.002,09422132071,V1.03.2136.003It's able to pull the software version from the unit. Any suggestions where to go from here?Edit 3: I modified the Device file so that the idString now has ÿÿÿÿÿÿÿ and I can get by that error message. On my until - in the SYS INFO area - the PRODUCT MODEL field is blank - the software/hardware versions are there - and that info was able to be pulled. I just verified that the native program from East Tester also now works (under a Virtualbox VM)...

One thing I advise all owners of these units is to check connection on the binding posts. Most of them come loose and if that's the case you will get voltage drop readings deceiving you on the real results. I own both ET5410A and ET5420A and they act defective because of that. After tight good all binding posts this units are working fine.

There is ways to modify the actual definition conditionally based on the #metadef used as can be seen in a lot of the definition files.If a file do not have a #metadef, it is easy to add.Before the first line starting with # add #meta and somewhere before that add a #metadef, then other #metadef can be added before that.
