Direct Serial logging

kutlee Wed Jun 27, 2018 1:46 pm

I am using a wideband from www.ecotrons.com. Product link below.
http://www.ecotrons.com/products/wideband_controller_alm-led/
They use rs232 adapter. I am using one as in the following link. (You can see the blue usb adapter in the ALM-LED wideband link as well.)
https://www.amazon.co.uk/adaptare-42103-USB-2-0-Adapter-RS232-COM-Windows/dp/B00594WPDW
Since there in no separate COM port(in the COM LPT of windows device manager) while i connect the wideband, i don't know what to choose in the neptune preferences for direct serial.
My ECU is shown up in the COM4 of the COM LPT windows device manager.
Is it possible to datalog through this type of USB adapter?

It should create a COM port and be usable if the device is working properly.

the device you linked to has a standard FTDI chip onboard, they are very standard and amazingly widely used, but are also a pain if you have certain other drivers installed. (it's close enough that windows uses it by default, but it does not work)
download the ftdi drivers from their site, update the driver to the new one (port and com) and it will show up as a COM port in device manager.

If the Demon shows up, so should it, as the Demon uses FTDI too!

Regarding Direct serial though, Neptune is only listed as support Innovate and PLX serial stream....
"Direct Serial Logging From LC-1, LC-2, LM-1, LM-2 (LM-2 USB Is Fully Supported on Windows), and PLX Wideband Products."

So even if you get that adaptor working, how will Neptune read the serial steam?

That is true and I'm assuming the protocol matches if he's trying, but to not see the COM port at all means he can't try!

I already have FTDI driver installed. I have the drivers installed which matches the windows OS 64 bit. So the drivers are correct. Anyways Neptune also uses FTDI chipset. But I am surprised that my wideband's USB adapter doesn't show a COM. This lead me to think that the particular a device that Ecotrons gave me, was another chipset for some reason. So I got a prolific chipset Serial to USB adapter and plugged that to my wideband. Now I can see a COM being created. But Neptune doesn't show any data on 'start direct serial' (although it turns to 'stop direct serial' which lead me to believe that Neptune is kind of 'receiving' some data). I did email Ecotrons for some help. But they can't say for sure anything beyond their GUI tool to set up the wideband parameters. Is there a way Neptune can be tweaked to read from USB without a COM interface? So some sort of virtual emulator or something of that sort.

It changes to stop when the port is open. If the datastream doesn't match one we support no data will likely be shown.

COM port is necessary other than Innovative which has their own plugin to manage USB.

I got reply from Ecotrons that the wideband uses KWP2000 protocol. I emailed FTDI for support and they said that their USB adapters don't support KWP2000 protocol.

found out that the wideband is HID usb device. so it converts KWP2000 to HID or something. I am not too technical here. So the device is not going to use a COM port. May be they did this for speed. I am not sure.
Can Neptune have some method to read HID data?

No, COM port is necessary like I mentioned. That doesn't sound like it's going to have a compatible protocol.
