I have a Topcon MR-2 modular receiver that I recently updated the firmware on. Getting the firmware file was quite a process, as the serial number would not register on the Topcon website (My Topcon). After many emails to the Topcon people I was told that the serial number was for a prototype unit that would not register in their system ???? They then referred me to my local dealer.
After even more e-mails to the dealer, (3 hours away) they finally sent me a firmware file for the receiver in question. The update process went smoothly and I received a "firmware has been successfully updated" message after only a few minutes. A quick check in TRU confirmed the firmware update, however, I also lost ALL the OAF options that had been activated on the receiver.
The dealer now says that they can no longer help me remotely, I need to send the unit in. The minimum charge would be several hundred dollars to run "diagnostics". Obviously I am hesitant to rack up a labor bill on this, and then possibly be told that I would need to spend thousands to reactivate the OAFs. I would not spend that much on this receiver.
According to the operator's manual, updating the firmware is a straightforward process and is intended to be able to be done by the end user. It also states that "the OAFs are stored in NAND memory and persist through firmware updates etc..." The dealer says they have never seen a firmware update erase OAFs.
The MR-2 receiver has the Topcon B125 GNSS board. This board is also used in the Hiper VR and also in at least one model of Sokkia receiver. It is a current model and is still available through Topcon/Sokkia.
I went from firmware version 5.1 to the current version of 5.5 in one step. Maybe this should have been done one version at a time. The dealer says they only have the file for the current version???
So my questions today are: has this ever happed to anyone else and how did they remedy it?
might the OAFs still be on the receiver, and the firmware somehow failed to extract/find them?
if so, is there a command that can be sent to the receiver to extract them?
would going back to firmware version 5.1 help, and does someone have the file?
Thanks in advance to anyone for any advice
