VictronConnect and VeFlash does not find Multiplus on MK3 usb dongle

Hello Forum !
I do have an issue with updating firmware on Multiplus-2 device using the MK3 USDB-to-VeBus dongle.
Neither VeFlash nor VictronConnect apps 'find' any device connected to the 'other' side of that unshielded-factory made RJ-45 cable 'behind' the USB-to-VeBus adaptor.
The PC is a Win7 machine with SP1, the Multiplus is a 48/3000/35-32 230V, just purchased, SN HQ2207FYF69V.
When using the VeConfigure program on that same PC, same same cable, all works fine
(i.e. i can 'get' and 'send' the config for that multiplus without issues).
all the programs (VeFlash, VeConfigure, VictronConnect) are on the latest downloadable version ...

That exact same thing happens with my 'old' (2017) Multiplus built into the 'EasySolar' box.
VeConfigure is ok, neither VeFalsh nor VictronConnect 'finds' that device.

If there is anyone out there who could point me to some more in-depth troubleshooting steps
(logfiles of VeFlash or VictronConnect ? - those glorious completely useless errormessages starting with 'unable' or 'failed' are not helping at all ...) or has another idea howto upgrade firmware on the Multiplus-es - much appreciated !

thanks a lot ,
Martin

Hello Alexandra !

The older multiplus has Version 2620408 with MK3 Version 1170212and the newer machine is 2629492

VeConfigure version is 90.04.230, VeFlash 90.05.159, VictronConnect is v5.72,
CCGX version 2.89 , build date 20220715132032

While i was able to update the BMV700 and both MPPT chargers as well as the ColorControl,
the 2620 Multiplus displays "Not updatable (1342 )" on the VRM portal.

When i try to connect the new Multiplus to the Ve.Bus (with another factory-made, unshielded
RJ-45 ehternet cable), the Bus goes to Error 17 and Error 3 .
I also connected the new Multiplus to the ColorControl using the MK3-to-USB dongle, but the
ColorControl did not recognize that device there (USB on the CCGX is working ok, since the
MPPT150/45rev3 device's Ve.Direct plug is connected to CCGX using Ve.Direct-to-USB adapter).

Concluding: VeFlash and VictronConnect do have an issue finding devices using the MK3-to-USB adapter, and VictronConnect does not find any device (neither in 'Local' nor in 'VRM' mode, where i would suggest VictronConnect programmers to allow setting the VRM portal access parameters inside the application instead of redirecting to the browser ... )

hope, this helps - thanks & happy Wednesday !

The inky thing I can think of here is the driver is not working for the Mk3.

Have you tried downloading the driver from the software page?

And then not using the autodetect for the com port. I kind of remember i had an issue with windows 7 and the port detection but it has been a while and have forgotten how to sort it. There was something along the lines of go in ng into device manager and seeing what comm it was using and manually setting it from there.

The inverter on 2629492 should update over the VRM. The newest firmware there is 2629497 so not far away from the latest. It should update over the VRM

Is the colour control one of the older ones listed as not being able to update connected devices over VRM?

See limitations here.

a mk3 IS JUST FOR PROGRAMING THE Multiplus units, it does not connect to the VRM nor the Victron connect directly.

Make sure that you are selecting a com port to connect the mk3 too you select this in VE Configure Program and the VE-flash program, you may have to do a manual comport selection. or look up the created com port thats alocated by the computer when you plug the usb into it.

Thanks, Paul - this is acknowledged - it was a trial to check, what happens.

for VeFlash, i am able to select the ComPort, for VictronConnect, i did not 'see' the option where to select a specific ComPort - the app seems to try and find the port itself ?

To repeat my question: is there some 'verbose' switch or logging option to get more details on what the app is trying to do and where and why excatly it fails ?

best regards, Martin
