    I've got an eDLT that needs a firmware update, but I can't seem to find any instructions on how to perform this. The eDLT is running 1.3.0, but I get a notice saying that there's a critical update available (1.5.0). I presumed I could simply connect the eDLT to a PC with the toolkit installed, wait a minute for the USB driver to be automatically installed and then proceed to update the firmware within the software.

    However, when I try this, I get the following error:

    I noticed that I don't get any additional devices appearing in device manager, so it looks like the eDLT isn't actually registering correctly with the PC. Am I missing any additional steps?

    Hi Ian
    You do need to have the eDLT connected to a C-Bus network as well as the USB connection to perform a firmware upgrade

    Thanks Colin. Do I need to install any drivers to get the eDLT detected on a Windows 10 PC? Nothing happens when I plug it in - i.e. nothing shows in device manager and no new devices are detected. I've tried 2 cables, but will also try a 3rd.

    Tried on a second laptop with a new cable - same result. Nothing appears in device manager when plugging the eDLT in (even if I manually install the drivers in the /firmware folder). The log doesn't show anything of interest, other than the device isn't detected.

    Am I missing a stage, or could there be a problem with the eDLT? It seems to work fine, apart from this issue.

    You need the
    • latest Toolkit installed,
    • CBUS (or 15v DC) power to the EDLT
    • USB connected AFTER EDLT has booted up from CBUS(/15v) connection
    If it's not being detected reinstall toolkit and there is an option to force the drivers in the install dialog

    Thanks, I'll re-install the toolkit and check that option to try again :).

    Another small but important note the usb leads you are using may not be suitable. Some leads of that design are used only to charge a device and only have 2 wires. Hence no comms.
    Just to double check you are plugging the USB lead into the side of the eDLT

    Can anybody help me. I was in the middle of a EDLT upgrade when the USB cable was accidentally bumped and the upgrade did not finish. The unit is now dead and I cannot re-install the firmware and the Toolkit software does not recognize the unit.
