That does not appear to be the case. If it did a reset the DAC should have gone to the InitV eeprom setting of 2.800V, but instead mine spiked to 0.308V which is not close to the InitV or the last known DAC values.

I emailed Trimble on the off chance they might have a firmware upgrade. They sent me an email which covered some units that rolled over in Feb. 2016 for which they say they have no upgrade. I sent them all the information on the label stuck to the outside of my TB (one of the group buy set), to see if there's any hope ... I'm not optimistic, but if you don't ask, you don't get.

Hi Trimble, even on supported products, is pretty firm about a service contract being in place for updates. The only exception seems to be security related patches. There have been a lot of examples of this over the years ….AFIK, there isn’t even a “public” firmware loader for the TBolt. Indeed, you might get lucky. Bob > On Jul 31, 2017, at 5:27 AM, David C.

> Unfortunately the unit that you have does not allow for a fw update. Oh well it was worth asking.
