Pieta Posted April 2, 2018 Share Posted April 2, 2018 Hi Gabriel Check in device manager if Communication Port is selected to Port 1? Gabriël 1 Quote Link to comment Share on other sites More sharing options...
Pieta Posted April 2, 2018 Share Posted April 2, 2018 These serial to Usb Devices usually select higher Port numbers when installing and if installed to a higher port number it might not be seen when you select Port 1? Quote Link to comment Share on other sites More sharing options...
ebrsa Posted April 2, 2018 Share Posted April 2, 2018 @gabriel I just run the updater from a Windows 7 laptop as a user and all works well. This is the same problem I had last time. Go to Control Panel on the laptop and open Device Manager. Look under Ports and see which COM port the USB to Serial converter selected. Mine selected COM2 last time. Then set the update program accordingly and try again. There is always a nail biting wait from the time the update program detects the COM port before it starts to upload the new firmware so just be patient for a minute or two. Make sure the firmware is 73.00b or you will have to upgrade again as I will have to do because only 73.00a was available when I updated about 3 weeks ago.

ebrsa Posted April 2, 2018 Share Posted April 2, 2018 Noticed your comments after I had posted mine @Pieta and we are telling the same story. The update program will certainly not see the COM port if you entered the wrong one. Good luck @gabriel. I hope all works well.

Gabriël Posted April 2, 2018 Author Share Posted April 2, 2018 hi pieta and ebrsa, there are no com ports listed under device manager [show hidden devices is ticked] and when i manage to install one it gives me error 34 and the axpert ignores it - i even tried a driver update from the manufacturer lenovo.... the search continues Quote Link to comment Share on other sites More sharing options...

Until you see a comm port in device manager, the reflash tool certainly won't find it. Windows can be prickly about device drivers, sometimes disabling it if it detects a few errors, and sometimes replacing the manufacturer's driver with one of its own, which doesn't work, all at no extra cost :-O I find the Prolific ones to work well, although a few years ago there was a hassle with clones using their drivers or something, and basically everyone had to buy a new one if they upgraded Windows. That should all be in the past now. But I don't know the supply situation in South Africa. I seem to recall some forum users posting what brands of usb to serial adapters they found to work properly. Good luck with it. Quote Link to comment Share on other sites More sharing options...
___ Posted April 3, 2018 Share Posted April 3, 2018 9 hours ago, Coulomb said: I find the Prolific ones to work well Interesting. On this side of the fence we kinda hate the prolifics and prefer Ftdi. But even there I've had a lot of fun. The software that comes with my Epson printer (for example) installs its own usb-serial driver that actually works, while the driver that ships with Victron's veconfigure stubornly refused to work on a new install, but the reference driver from ftdi itself worked perfectly. In Linux land, strangely enough compared to the early years, driver issues are largely unheard of these days. As long as it's not for something made by Nvidia you're good.

ebrsa Posted April 3, 2018 Share Posted April 3, 2018 @gabriel I opened Device Manager on my Windows10 PC and checked the Ports. I had 2 COM ports active. Then plugged my Unitek USB-Serial converter into a USB hub connected to the PC and immediately it was recognised as Prolific USB to Serial Converter (COM4). I bought it from https://scoop.co.za/ in Montague Gardens, just off the N7 turnoff at the refinery but in a side street to the right. Or perhaps you can mail order it. Look under Manufacturers > Green Connection where a USB-Serial converter is listed although not Unitek but Green Connection. As a first effort I would suggest that you try and find the right driver for the converter that you have. However from information on the Internet it would appear that some of these converters just don't work properly as they use a copy of the Prolific chip. The last thing you want is an unreliable connection to your Axpert when flashing firmware. Which brand is your Axpert. Mine is branded Proline from Pinnacle and since I have never had any problems in flashing the firmware, I am confident it is a rebranded Voltronics Axpert. Hopefully yours is also the genuine article, otherwise it may not be a good idea to try flashing the firmware as @Coulomb has often warned. Good luck but don't hesitate to request help if things remain troublesome. Gabriël 1 Quote Link to comment Share on other sites More sharing options...
Gabriël Posted April 3, 2018 Author Share Posted April 3, 2018 hi @Coulomb, @ebrsa, @Pieta and @plonkster, first off, thanks for the tips and warnings. the laptop in question shows no ports at all in dm [win10 home], so i have a friend's pc with a serial port and will try later today. from what i read usb to serial converters are not all the same, so even if the serial com port had existed on the laptop device manager i might have run into complications with the cable. with the pc's serial port i may succeed. some posts, even on this forum, lead me to believe that updating firmware to clones will not be possible in order to inter alia protect proprietary software/hardware. apart from the latter i can find no way of ascertaining whether the unit you have is a clone or the real maccoy. my installer said he can't update the firmware - 'a specialist' has to do it; not that i want my installer involved, but its a matter of warranty, which only lapses on 19 april [i'm at least keeping him in the loop, you'll understand if i mention i found out he's a fly-by-nite without a wiremen's certificate but is pretty active on the west coast]. if the 'specialist' brick's the axpert, well, so be it, then it has to be replaced. any thoughts?

ebrsa Posted April 3, 2018 Share Posted April 3, 2018 Hi @gabriel, the problem is that if the "expert" bricks your inverter, he may turn on to be an even more agile fly by night and simply disappear, leaving you with the expensive brick. What brand name appears on your inverter or perhaps you could post a photo or two so folks can see if it can be identified. I for one would be really interested to see what is being sold whether the genuine article or not. My USB-Serial converter has worked flawlessly thus far and I have flashed several versions of the CoulombWeber firmware to four inverters at several times without mishap. That includes flashing the version 4.1 of the SCC firmware. I hope the computer with serial port does the job for you. It seems to me that the real experts are to be found on this forum and advice is always forthcoming when one posts a question. Best policy is to learn from these fellows rather than some off the street "expert" recommended by an installer about whom you already have reservations. Best expert is always oneself because it is your pocket that will be hammered if things go wrong. Chris Hobson and Gabriël 1 1 Quote Link to comment Share on other sites More sharing options...
Gabriël Posted April 3, 2018 Author Share Posted April 3, 2018 hi @ebrsa, my hahaha to your comment is aimed more at myself then the situation, i.e. the only way i can resolve chaos at times i attach some images, i can see the brand of the internal fans is adda... genuine.pdf Quote Link to comment Share on other sites More sharing options...
ebrsa Posted April 3, 2018 Share Posted April 3, 2018 @gabriel yours is a Rectron rebranded Voltronics, RTC being the Rectron logo. Since Rectron is a subsidiary of Mustek with their Mecer brand, it is virtually 100% certain that it is a Voltronics rebrand. My first inverter was an RTC 3KVA which I sold and upgraded to 2 x Proline 4KW units in parallel, mainly because I did not fancy having the house rewired to keep the lights, TV and computers going during the time of Eskom rolling blackouts, even though I made provision for installing additional cables when the house was built. Just too much work and the 8KW capacity I have now has only tripped once, due to overload, during the past year or so. I guess one could expect that you should not encounter firmware upgrade problems but who can tell with the lack of integrity of some suppliers locally. I doubt that Mustek or Rectron would put their reputation at risk by selling inferior clones thoug,h since to my knowledge they did sell the genuine Voltronics units in the past.

Actually, if you don't have the genuine article, I have two pieces of advice. 1. Try really hard not to buy non-genuine in future. Of course Voltronic don't make it easy for you to know which is which. Maybe they'll try harder in future. 2. Stop running either 73.00 or 73.00a firmware. I hate to say it, but if you are running either of these, you might have as little as a few days to save your machine from brickdom. I literally found out I had 109 hours before my machine would have stopped working. Fortunately for me, just stopped, not bricked; as mine is definitely genuine. I suspect that many people will get caught with this one over the next month or so.

ebrsa Posted April 3, 2018 Share Posted April 3, 2018 Thanks a great deal for the warning @Coulomb. I will definitely upgrade my Axperts to 73.00b in the morning. Is there a relatively easy way to find out how much time remains before catastrophe strikes. Quote Link to comment Share on other sites More sharing options...

ebrsa Posted April 3, 2018 Share Posted April 3, 2018 @gabriel why not give Rectron in Montague Gardens a call and ask them to confirm that the unit they sell is a genuine Voltronics for absolute peace of mind.I have not dealt with them for years so you may have to try Mustek in Cape Town if you cannot find a telephone number for Rectron.

Gabriël Posted April 3, 2018 Author Share Posted April 3, 2018 ok gents, with all your good advice etc and a call to rectron [cape town, keith is the man] i established the following: the unit is genuine it is still under warranty [2years from purchase] the firmware update must be done by them in jhb, i.e. i've got to take it off the wall, 'un-cable' it and take it to rectron cpt from where they send it to jhb etc. so now, if it get's bricked its on them Quote Link to comment Share on other sites More sharing options...
ebrsa Posted April 3, 2018 Share Posted April 3, 2018 @gabriel I would be surprised if they flash it with @Coulomb and @weber firmware. At best probably the Voltronics 73.00 version with all the flaws fixed by Coulomb and Weber. However if it is still under guarantee for some time, perhaps it is best to carry on until the guarantee runs out before flashing with whatever is the latest Coulomb/Weber firmware.

Gabriël Posted April 3, 2018 Author Share Posted April 3, 2018 hi @ebrsa, you've got a point there! the warranty will expire next month and then i have to update again and schlepp to capetown and back twice and sit without solar for maybe two weeks... hmmm... its a no-brainer. i'll rather harvest some skywatts and do something productive in the meantime - like preparing for the big rain and cometh the hour flash with 73.00b from down under, voila, fixed Pieta 1 Quote Link to comment Share on other sites More sharing options...
Pieta Posted April 5, 2018 Share Posted April 5, 2018 Gabriel sure if you can sort out the comms problem you would be able to reflash it yourself without getting it bricked by an "a"xpert! Always nice to learn by doing it yourself and there is really very good reading material on this forum to help. After all the prep work for the big rains you might still have some time to sort it before the warranty expire! Gabriël 1 Quote Link to comment Share on other sites More sharing options...
