Error message

[Aqualab]

I keep getting this error message below while trying to download firmware version 500m. Profilux Plus II

Error while transmitting firmware!: flasherase - no response - 8


I am using software version V50010.

Issue?

[Matthias]

many thanks for the hint!

should be solved with today's update

please let me know if it working now for you

[Aqualab]

Your'e welcome.

I downloaded firmware version 500m just now and it loaded successfully. But now I can't connect - error message 28! I am using version 5.0.0.9 software because 5.0.0.10 hangs up on me.

[Aqualab]

Installed version 5.0.0.11 to see if it makes any difference - did not. Continue to get error code 28 when trying to connect via USB.

[Matthias]

please check the connection settings, maybe they got lost during update 5.0.0.9 -> 5.0.0.1x

[Aqualab]

Checked the settings immediately after download - no changes.

Remember:
if you take a different USB port on your computer it can happen that your computer assigns a different com port. Then you need to update the connection details.

in my case I get either com 4 or com 9 if I take 1 or the 2 usb on the front of my computer.

[Aqualab]

I have used just one USB port throughout initial install and upgrade process - kind of dedicated it. It is still coming up as com port 6 in the GHL program and in the device manager. Just won't go through, gives the error message.

[Matthias]

are we talking about PLM-USB or a third-party USB-converter?

[Aqualab]

It is a PLM-USB

[Matthias]

is this the newest USB-driver from our site?

there is no reason why it should not work - if the ProfiLuxControl communication settings match the windows harwdare manager settings it must work

do you want to post some screenshots?

[Aqualab]

Yes, latest driver. I have windows 7 on my laptop. The CD that came with the GHL USB module did not have a windows 7 driver on it.

[Aqualab]

I noticed that the PLM-USB windows 7 driver says Prolific USB to serial comm port (Comm 6) Port_#0002.Hub_#0005 in my device manager? Shouldn't it be USB to USB? The device manager also says Comm 6 but when clicking on the general tab I see it says Port 2? Shouldn't it say Port 6 also? Bottom line is it worked fine until firmware version 5.00m was installed.

[Aqualab]

I tried using a different USB port on my laptop - recognized as comm port 7 in manager. Profilux control started to communicate (green bar moving very slowly) after a long time it said comm established but the menu still only showed general and email notification. I waited.................. nothing so I closed out and restarted profilux control - now no comm again error 28. Tried multiple times. I then rloaded ver 5.09 and tried same thing - no comm error message 28. Adjusted baud rates, still no connection.

[Aqualab]

I set baud to 9600 for the USB device in manager and the connection speed in control manager - starts to connect (green bar slowly moves to right) then it freezes, i get a not responding message at top of control manager. Getting ********** again with profilux.

[Aqualab]

it finally connected - very slow to connect - menu is slow, whatever I select is slow to pop up. What is causing this?

[Aqualab]

I went back to 5.08 and it works fine, not slow, connects quickly. So i am now using 5.00m and 5.08. So I have established that the problem is not with my laptop but with the upgrades. Guess I will stick with 5.08 unless you can tell me why the upgrades are causing so many problems?

[Matthias]

Prolific USB to serial comm port is correct

there must be something wrong with your system - the things you described are not normal

Firmware 5.00o and ProfiLuxCOntrol 5.0.0.11 work great together

maybe you try another COM-port - change it in the device manager to something else, e.g. 4 and change the setting in ProfiLuxControl accordingly
sometimes there are conflicts between several USB-devices, they can be solved when assigning other numbers
