MBL1660 reset to defaults now shows as MBL1330

Hi, my buddies and I are working with an MBL1660 and we had to reset the values. I clicked the Reset Defaults button on the Roborun+ control utility and now the controller shows as an MBL1330, we know it was an MBL1660 because we ran it with 48V and we had the profile saved, now it won't accept the profile and it does not change back to MBL1660. I've tried reinstalling the firmware update but still shows as an MBL1330. What can I do? our application needs to be higher and the device is less than a year old. Any help will be great.

Hello,

this does not make any sense, since whether the board is MBL1330 or MBL1660 depends on the presence of a resistance. When you reset to default this resistance is not affected.

- Send me the response of the ?trn query.
- Send me screenshot of the label under the board.
- If possible open the case and look for resistance R77. If it is not there you have MBL1330, if it is there you have MBL1660.

Off memory, since I've been trying for a while i can tell you the ?TRN command replies with TRN=MBL1XXX:MBL1330 FID=<current firmware download from the roboteq site>. The image of the labels are attached. I'll have to open the device and check for the R77 location. Thank you for your reply.

Hello,

The R77 seems to be damaged, thus the MBL is now seen as 1330 instead of 1660.

If you are familiar with soldering you can clear this spot and put a 10 Ohm resistance. If you do not want to take that responsibility then report the issue to customer service department (This email address is being protected from spambots.
